Although the above air conditioner can control the temperature of each living room, there is room for improvement in reducing the initial cost required for introducing the air conditioner.

On the other hand, in order to reduce the initial cost, for example, it is conceivable to reduce the number of dampers. However, if the number of dampers is reduced, it becomes difficult to adjust the supply amount of air-conditioned air, and there is a problem that each living room cannot be controlled to a preset temperature.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide an air conditioning system capable of controlling the temperature of a space in a building while reducing the initial cost.

And a fan for supplying the conditioned air heat exchanged by the air conditioner to the inlet of the chamber, in the chamber, the conditioned air supplied to the inlet is inside the chamber. It is formed so as to flow in a predetermined first direction, and the outlets of the chamber supply the conditioned air to the first space and the conditioned air to the second space. The second outlet is provided at the downstream end of the chamber in the first direction, and the first outlet is more than the second outlet. The conditioned air is discharged on the upstream side of the first direction and in a direction intersecting the first direction, and the second outlet is an air path having a damper capable of adjusting the air volume of the conditioned air. The first outlet communicates with the first space without having the damper.

In the air conditioning system according to the present invention, the chamber may be a long body having a relatively large length in the first direction.

The air conditioning system according to the present invention further includes a control device for adjusting the damper, and the control device measures the air volume when the temperature of the second space reaches a preset target temperature. The throttle may increase the air volume of the conditioned air to the first space.

In the air conditioning system according to the present invention, when the damper is fully opened, the effective opening area of at least one second outlet of the chamber may be smaller than the effective opening area of the first outlet.

In the air conditioning system according to the present invention, the building may be a house, the first space may be a living room, and the second space may include a washroom.

In the air conditioning system according to the present invention, the chamber may include an opening / closing means capable of adjusting the opening area of the first outlet.

FIG. 1 is a conceptual diagram showing an example of a building (house) 2 using the air conditioning system 1. As the building 2, the case where it is a house is exemplified, but it may be a building or the like. The building 2 includes a first space 3 and at least one second space 4 having a volume smaller than that of the first space 3.

The first space 3 of the present embodiment is a living room 5. In general, the living room 5 tends to have a longer resident stay time than other spaces in the building 2. The first space 3 is not limited to the living room 5 as long as it has a larger volume than the second space 4.

The second space 4 can be appropriately selected as long as it is a space smaller than the first space 3. The second space 4 of the present embodiment includes a washroom 6. Further, the second space 4 of the present embodiment includes a guest room (Japanese-style room) 7. In general, in the washroom 6 and the guest room 7, the resident's staying time tends to be shorter and the heat load fluctuation tends to be larger than in the living room 5. The second space 4 of the present embodiment may include, for example, a bedroom, a children's room, or the like (not shown).

The air conditioning system 1 includes an air conditioner 11, a chamber 12, and a fan 13. In the present embodiment, the air conditioner 11 and the fan 13 are housed inside the housing 14, but the present invention is not limited to such an embodiment.

The housing 14 of this embodiment is installed on the floor. The installation location of the housing 14 is not particularly limited, and may be installed in a space under the floor (underfloor space 9) or in the back of the cabin, for example. Further, although the housing 14 is installed on the floor on the first floor, it may be installed on the floor on the second floor or higher (not shown), for example.

The housing 14 is formed in a box shape having a space inside. The air conditioner 11 and the fan 13 are housed inside the housing 14. The housing 14 of the present embodiment is provided with an air supply port (not shown) and an outside air intake port 16, but only one of the air supply port and the outside air intake port 16 may be provided. ..

The air supply port (not shown) is for supplying the air A3 circulating in the first space 3, the second space 4, and the like to the inside of the housing 14. The air supply port communicates between the space inside the building 2 and the inside of the housing 14.

The outside air intake port 16 is for taking in the outside air A1 (underfloor air A2) inside the housing 14. A duct 17 is connected to the outside air intake port 16 of the present embodiment. The duct 17 communicates the inside of the housing 14 with the underfloor space 9 (shown in FIG. 1). As a result, the outside air intake port 16 can take in the outside air A1 (underfloor air A2) into the inside of the housing 14 via the underfloor space 9 and the duct 17.

The duct 17 is provided with an outside air supply fan 18 for sending the underfloor air A2 (outside air A1) to the outside air intake port 16. The air volume of the outside air supply fan 18 can be appropriately set, and is preferably set based on, for example, the ventilation frequency required for the building 2. In the present embodiment, the outside air A1 (underfloor air A2) is taken in through the underfloor space 9, but the outside air A1 may be taken in directly from the outside.

As the air conditioner 11 of the present embodiment, a case where it is a general household separate type air conditioner is exemplified. The air conditioner 11 includes an indoor unit 11A and an outdoor unit (not shown) installed outside the building 2 as a set. The indoor unit 11A has a suction port 21 and a discharge port 22. The suction port 21 is for taking air into a heat exchanger (not shown) inside the indoor unit 11A. The discharge port 22 is for discharging the heat-exchanged conditioned air A4.

An air supply port (not shown) and an outside air intake port 16 are provided in the vicinity of the suction port 21 of the indoor unit 11A (above the suction port 21 in this embodiment). As a result, the air conditioner 11 can air-condition the air-conditioned mixture of the air A3 circulating in the space (for example, the first space 3 and the second space 4 and the like) and the underfloor air A2 (outside air A1). The inside of the building 2 can be ventilated and air-conditioned while circulating air inside the building 2.

The conditioned air A4 may be purified by a filter (not shown) provided inside the housing 14. As a result, the air conditioning system 1 can supply the purified air to the first space 3 and the second space 4.

The fan 13 is for supplying the conditioned air A4 to the inlet 23 of the chamber 12. Since the fan 13 of the present embodiment is provided separately from the air conditioner 11, the air conditioner 11 and the fan 13 can be maintained individually.

The fan 13 of the present embodiment supplies the conditioned air A4 to the inlet 23 of the chamber 12 via the duct 26. As the fan 13, for example, a sirocco fan can be adopted, but the fan 13 is not limited to such an embodiment. In the present embodiment, it is composed of one fan 13, but it may be composed of a plurality of fans 13. The air volume of the fan 13 can be appropriately set, and is preferably set based on, for example, the ventilation frequency required for the building 2.

FIG. 2 is a perspective view showing an example of the chamber 12. FIG. 3 is a cross-sectional view of FIG. The chamber 12 is formed in a box shape having a space inside thereof. The chamber 12 of the present embodiment includes an upper plate 12a, a lower plate 12b, and a side plate 12c connecting the upper plate 12a and the lower plate 12b, and is formed to have a substantially rectangular cross section. As shown in FIG. 1, the chamber 12 of the present embodiment is installed in the space above the ceiling (behind the cabin) on the first floor, but is not particularly limited, and is, for example, in the underfloor space 9. It may be installed.

As shown in FIGS. 2 and 3, the chamber 12 is provided with an inlet 23 and a plurality of outlets 24. The chamber 12 is formed so that the conditioned air A4 supplied to the inlet 23 flows inside the chamber 12 in a predetermined first direction D1. As shown in FIG. 2, the chamber 12 is formed in a long body having a relatively large length L1 in the first direction D1 in order to form a flow of the conditioned air A4 in the first direction D1. Is desirable. The length L1 of the first direction D1 of the present embodiment is the length L2 of the direction orthogonal to the first direction D1 (hereinafter, may be simply referred to as "second direction D2" and "third direction D3") and It is formed larger than L3.

As shown in FIGS. 2 and 3, the inlet 23 is provided on the upstream side of the first direction (direction in which the conditioned air A4 flows) D1 of the chamber 12. The inlet 23 of the present embodiment is provided on the upper plate 12a of the chamber 12, but may be provided on the lower plate 12b or the side plate 12c. As described above, the inlet 23 is connected to the fan 13 (shown in FIG. 1) via the duct 26. As a result, the conditioned air A4 heat exchanged by the air conditioner 11 is supplied to the chamber 12 via the fan 13 and the duct 26.

As shown in FIG. 2, the plurality of outlets 24 are configured to include a first outlet 24A and at least one second outlet 24B.

The first outlet 24A is for supplying the conditioned air A4 to the first space 3 (shown in FIG. 1). The first outlet 24A is provided on the upstream side of the first direction D1 with respect to the second outlets 24B and 24B. Further, the first outlet 24A of the present embodiment is provided on the side plate 12c arranged in the direction intersecting the first direction D1 (in this example, the second direction D2). As a result, the first outlet 24A can discharge the conditioned air A4 flowing in the first direction D1 in the direction intersecting the first direction D1 (second direction D2). An embodiment in which the first outlet 24A of the present embodiment is provided on the side plate 12c is exemplified, but the upper plate 12a and the lower plate arranged in the direction intersecting the first direction D1 (in this example, the third direction D3). It may be provided in 12b.

The first outlet 24A communicates with the first space 3 without having a damper 30 as provided at the second outlet 24B. Therefore, since the number of dampers 30 can be reduced in the air conditioning system 1, the initial cost required for introducing the air conditioning system 1 can be reduced.

The first outlet 24A of the present embodiment communicates with the opening 33 of the first space 3 via the covering portion 34, but the first outlet 24A may be provided facing the first space 3. good. Since such a first outlet 24A can directly supply the conditioned air A4 to the first space 3, an air path such as a duct or the like between the first outlet 24A and the first space 3 (not shown). ) Does not need to be provided. Therefore, the initial cost required for introducing the air conditioning system 1 can be reduced. When the first outlet 24A and the first space 3 are separated from each other, an air path such as a duct may be provided between the first outlet 24A and the first space 3.

As described above, the first space 3 (living room 5 in this example) shown in FIG. 1 has a larger volume than each second space 4 (washroom 6 and guest room 7 in this example). The effective opening area of the first outlet 24A may be set larger than the effective opening area of at least one second outlet 24B so that a large amount of conditioned air A4 can be supplied to the first space 3. When a plurality of second outlets 24B and 24B are provided as in the present embodiment, the effective opening area of the first outlet 24A is set to be larger than the effective opening area of each second outlet 24B. .. Further, the effective opening area of the first outlet 24A and the effective opening area of the second outlet 24B can be appropriately set based on, for example, the volumes of the first space 3 and the second space 4.

The second outlet 24B is for supplying the conditioned air A4 to the second space 4 (shown in FIG. 1). In the present embodiment, two second outlets 24B and 24B are provided in order to supply the conditioned air A4 to each of the plurality of second spaces 4 (in this example, the washroom 6 and the guest room 7 shown in FIG. 1). Has been done. In addition, depending on the number of the second space 4 to which the conditioned air A4 is supplied, three or more second outlets 24B may be provided.

The second outlets 24B and 24B are provided at the downstream end 27 of the chamber 12 in the first direction (direction in which the conditioned air A4 flows) D1. The second outlets 24B and 24B of the present embodiment are provided on the side plates 12c intersecting the first direction D1, respectively. Such second outlets 24B and 24B can discharge the conditioned air A4 flowing in the first direction D1 inside the chamber 12 along the first direction D1. Therefore, the second outlets 24B and 24B provide the conditioned air A4 as compared with the first outlet 24A which bends and discharges the conditioned air A4 in the direction intersecting the first direction D1 (in this example, the second direction D2). It can be discharged smoothly. As a result, the chamber 12 of the present embodiment can prevent the conditioned air A4 from being preferentially discharged from the first outlet 24A having a large opening area.

The second outlets 24B and 24B communicate with the second spaces 4 and 4 (shown in FIG. 1) via air paths (ducts in this example) 28 and 28, respectively. Each of these air paths 28 and 28 has a damper 30 capable of adjusting the air volume of the conditioned air A4. The damper 30 of the present embodiment is, for example, an electric damper driven by an electric motor 30a, but is not limited to such an embodiment as long as the air volume of the conditioned air A4 can be adjusted.

The larger the opening degree (opening area) of the damper 30, the larger the supply amount of the conditioned air A4 can be. The damper 30 of the present embodiment is configured to be adjustable to at least a first opening degree and a second opening degree smaller than the first opening degree.

The first opening and the second opening can be set as appropriate. The first opening degree of the present embodiment is set to the opening degree (90% to 100%) when the damper 30 is fully opened. On the other hand, it is desirable that the second opening degree is set to a ventilable opening degree (for example, 2% to 10%) in consideration of the ventilation frequency required for the building 2 (shown in FIG. 1). As the damper 30, one that can be set to three or more opening degrees different from each other may be adopted.

In the chamber 12 of the present embodiment, when the damper 30 is fully opened (set to the first opening degree), the effective opening area of at least one second outlet 24B is set to be smaller than the effective opening area of the first outlet 24A. ing. When a plurality of second outlets 24B and 24B are provided as in the present embodiment, the effective opening area of each of the second outlets 24B and 24B is larger than the effective opening area of the first outlet 24A. Set small. As a result, the air conditioning system 1 can prevent the supply of the air conditioning air A4 to the first space 3 from being lowered when the damper 30 is fully opened.

As shown in FIG. 1, the air conditioning system 1 includes a control device 31 for adjusting the opening degree of the damper 30. The control device 31 includes a calculation unit (not shown) composed of a CPU (central processing unit), a storage unit (not shown) in which control procedures are stored in advance, and a working memory (not shown) for reading control procedures from the storage unit. ) And are included. Such a control device 31 is installed on, for example, a partition wall or the like.

A damper 30 (electric motor 30a shown in FIG. 2) is connected to the control device 31. As a result, the control device 31 of the present embodiment can adjust the opening degree of the damper 30 by transmitting a signal to the damper 30. The target temperature of the space (first space 3 and second space 4) in the building 2 is input to the control device 31 of the present embodiment, for example, via an input means (not shown). The control device 31 adjusts the opening degree of the damper 30 based on these target temperatures and a predetermined procedure.

An air conditioner 11, a fan 13, and an outside air supply fan 18 may be connected to the control device 31. Thereby, the control device 31 can control these operations.

A temperature detecting means (not shown) for detecting the temperature of the first space 3 and the temperatures of the second spaces 4 and 4 is connected to the control device 31 of the present embodiment, respectively. As a result, the control device 31 transmits a signal to each temperature detecting means to detect the temperatures of the first space 3 and the second spaces 4, 4 and transmit the detection results to the control device 31. be able to.

FIG. 4 is a flowchart showing an example of a processing procedure of the air conditioning system 1 (hereinafter, may be simply referred to as an “air conditioning method”). This processing procedure is carried out based on the control procedure stored in the control device 31 (shown in FIG. 1).

In the air conditioning system (air conditioning method) of the present embodiment, first, the control device 31 starts air conditioning of the building 2 (step S1). In step S1 of the present embodiment, first, the control device 31 starts the operation of the air conditioner 11, the fan 13, and the outside air supply fan 18. In step S1 of the present embodiment, the set temperature of the air conditioner 11, the air volume of the fan 13 and the outside air supply fan 18, and the like are set based on the target temperature and the like input by the resident to the control device 31.

Further, in step S1, the opening degree of each damper 30 shown in FIG. 2 is set to fully open (in this example, the first opening degree). As described above, in the chamber 12 of the present embodiment, when the damper 30 is fully opened, the effective opening area of each of the second outlets 24B and 24B can be made smaller than the effective opening area of the first outlet 24A. Therefore, in step S1, it is possible to prevent the supply to the first space 3 from being lowered while preferentially supplying the conditioned air A4 supplied to the chamber 12 to the second spaces 4 and 4.

The volumes of the second spaces 4 and 4 are smaller than those of the first space 3. Since the conditioned air A4 is preferentially supplied to the second spaces 4 and 4, the conditioned system 1 sets the temperature of each of the second spaces 4 and 4 having a short staying time and a large heat load fluctuation. , The target temperature can be reached early.

Next, in the air conditioning system (air conditioning method) of the present embodiment, the control device 31 determines whether or not the temperature of the second space 4 has reached a preset target temperature (step S2). In step S2, first, for each of the second spaces 4, the difference between the temperature detected by the temperature detecting means (not shown) (hereinafter, may be simply referred to as “detection temperature”) and the target temperature (hereinafter, referred to as “detection temperature”). , Simply "temperature difference") is required. When the air conditioner 11 is in the heating operation, the temperature difference can be obtained by subtracting the detected temperature from the target temperature. On the other hand, when the air conditioner 11 is in the cooling operation, the temperature difference can be obtained by subtracting the target temperature from the detected temperature.

Next, in step S2 of the present embodiment, the control device 31 determines whether or not the temperature difference is smaller than the predetermined first threshold value. The first threshold value is for determining whether or not the temperature of the second space 4 has reached the target temperature. The first threshold value can be set as appropriate. The first threshold of the present embodiment is set to -1 ° C. By comparing such a first threshold with the temperature difference, whether or not the temperature of the second space 4 at the time of heating becomes higher than the target temperature, or the temperature of the second space 4 at the time of cooling is the target. It is possible to judge whether or not the temperature has become lower than the temperature. Therefore, the first threshold value can reliably determine whether or not the temperature of the second space 4 has reached the target temperature.

In step S2, when the temperature difference is smaller than the first threshold value (-1 ° C. in this example), the temperature of the second space 4 is the target temperature (“Y” in step S2). In this case, step S3 is performed in which the air volume of the conditioned air A4 to the second space 4 is reduced and the air volume of the conditioned air A4 to the first space 3 is increased.

In step S3, the control device 31 sets the opening degree of the damper 30 to be small. In the present embodiment, the opening degree of the damper 30 is set to the second opening degree (for example, 4%). As a result, the air volume of the conditioned air A4 to the second space 4 is reduced. In step S3, it is desirable that only the air volume to the second space 4 that has reached the target temperature is throttled out of the plurality of second spaces 4. As a result, the air volume of the other second space 4 that has not reached the target temperature is maintained, so that the temperature of the second space 4 can be reached to the target temperature at an early stage.

In step S3, the decrease in the air volume of the conditioned air A4 to the second space 4 can be applied to the air volume of the conditioned air A4 to the first space 3. As a result, the air volume of the conditioned air A4 to the first space 3 can be increased. Therefore, in the air conditioning system 1 of the present embodiment, even if the number of dampers 30 is reduced, the air volume of the air conditioning air A4 to the first space 3 and the second space 4 can be adjusted, so that the first space 3 and the first space 3 and the first space 4 can be adjusted. The temperature of 2 spaces 4 can be controlled.

As described above, since the volumes of the second spaces 4 and 4 are smaller than those of the first space, the target temperature is reached early. Therefore, in the air-conditioning system 1 of the present embodiment, after the temperature of the second space 4 reaches the target temperature, the air volume of the conditioned air A4 to the first space 3 can be rapidly increased, so that the first space can be increased. It is possible to suppress the decrease in the air conditioning of 3. Therefore, the air conditioning system 1 of the present embodiment can effectively air-condition both the first space 3 and the second spaces 4 and 4 respectively.

On the other hand, if the temperature difference is equal to or greater than the first threshold value (-1 ° C. in this example) in step S2, it is highly possible that the temperature of the second space 4 has not reached the target temperature (“N” in step S2). ). In this case, the control device 31 increases the air volume of the conditioned air to the second space 4 (step S4).

In step S4 of the present embodiment, the control device 31 sets the opening degree of the damper 30 to the first opening degree (for example, 100%). If the opening degree of the damper 30 is already set to the first opening degree, the opening degree is maintained. In step S4, it is desirable to increase only the air volume to the second space 4 that has not reached the target temperature among the second spaces 4 and 4. As a result, the air conditioning system can increase the air volume of the air-conditioned air A4 in the second space 4 until the temperature of the second space 4 reaches the target temperature, so that the second space 4 can be effectively air-conditioned. can.

Next, in the air conditioning system (air conditioning method) of the present embodiment, the control device 31 determines whether or not there is a stop command for the air conditioning system 1 (step S5). The stop command is input to the control device 31 by the resident, for example.

When it is determined in step S5 that there is a stop command (“Y” in step S5), the control device 31 stops the air conditioning system (air conditioning method) 1 (step S6). On the other hand, if it is determined in step S5 that there is no stop command (“N” in step S5), the control device 31 re-executes steps S2 to S5.

As described above, in the air conditioning system (air conditioning method) 1 of the present embodiment, the air volume of the air conditioning air A4 to the first space 3 and the second spaces 4 and 4 can be adjusted until a stop command is given. The temperature of the first space 3 and the temperatures of the second spaces 4 and 4 can be continuously controlled.

In the air conditioning system 1 of the conventional embodiment, the opening degree of the damper 30 is two opening degrees (first opening degree and second opening degree) based on the temperature difference between the temperatures of the second spaces 4 and 4 and the target temperature. Although the case where the opening degree is set is exemplified, the present invention is not limited to such an aspect. For example, the opening degree of the damper 30 may be set to three or more opening degrees based on the magnitude of the temperature difference. FIG. 5 is a flowchart showing an example of a processing procedure (air conditioning method) of the air conditioning system 1 of another embodiment of the present invention. In this embodiment, the same configurations as those in the previous embodiments are designated by the same reference numerals, and the description thereof may be omitted.

In this embodiment air conditioning system (air conditioning method), when it is determined in step S2 that the temperature of the second space 4 has not reached the target temperature (“N” in step S2), it is based on the magnitude of the temperature difference. Then, the opening degree of the damper 30 is finely adjusted (fine adjustment step S7). FIG. 6 is a flowchart showing an example of the fine adjustment step S7.

In the fine adjustment step S7 of this embodiment, first, the temperature difference is compared with a predetermined threshold value (first threshold value to fourth threshold value) (step S71), and the opening degree of the damper 30 is finely adjusted. (Steps S72 to S75).

In step S71, when the temperature difference is equal to or greater than the first threshold value (-1 ° C. in this example) and less than the second threshold value (0 ° C. in this example), in step S3 (shown in FIG. 5). The third opening degree (for example, 33% to 43%) is set to be larger than the second opening degree (step S72). On the other hand, when the temperature difference is equal to or more than the second threshold value (0 ° C. in this example) and less than the third threshold value (1 ° C. in this example), the fourth opening degree (1 ° C. in this example) is larger than the third opening degree ( For example, it is set to 62% to 68%) (step S73).

In step S71, when the temperature difference is equal to or greater than the third threshold value (1 ° C. in this example) and less than the fourth threshold value (2 ° C. in this example), the fifth opening is larger than the fourth opening degree. It is set to a degree (for example, 69% to 73%) (step S74). On the other hand, when the temperature difference is equal to or larger than the fourth threshold value (2 ° C. in this example), it is set to the first opening degree (90% to 100% in this example) larger than the fifth opening degree (step S75). ).

As described above, in the fine adjustment step S7 of this embodiment, the opening degree of the damper 30 can be increased as the temperature difference increases. As a result, in the fine adjustment step S7, the air volume of the conditioned air A4 to the second space 4 can be increased, so that the second space 4 can be effectively conditioned. On the other hand, in the fine adjustment step S7, the smaller the temperature difference, the smaller the opening degree of the damper 30. As a result, in the fine adjustment step S7, the air volume of the conditioned air A4 to the second space 4 can be reduced, so that the decrease in the air volume of the conditioned air A4 to the second space 4 is transferred to the first space 3. It can be used for the air volume of the conditioned air A4. Therefore, the air conditioning system (air conditioning method) 1 of this embodiment can efficiently air-condition the first space 3 and the second space 4.

By the way, in the air conditioning system 1 of the conventional embodiment, the air volume of the first space 3 cannot be increased from the start of air conditioning of the building 2 until the second space 4 reaches the target temperature, so that the first space It may take time for the air conditioning of 3. Therefore, when a resident is staying in the first space 3, it is desired to quickly air-condition the first space 3.

In order to quickly air-condition the first space 3, it is effective to increase the opening area of the first outlet 24A (shown in FIG. 2) to increase the air volume of the air-conditioned air A4 to the first space 3. However, if the opening area of the first outlet 24A is always set to be large, there is a problem that the second space 4 cannot be preferentially air-conditioned. Therefore, the chamber 12 may include an opening / closing means capable of adjusting the opening area of the first outlet 24A. FIG. 7 is a partial perspective view showing the chamber 12 of another embodiment of the present invention. In this embodiment, the same configurations as those in the previous embodiments are designated by the same reference numerals, and the description thereof may be omitted.

In the chamber 12 of this embodiment, when the opening / closing means 36 is removed (not shown), the opening area of the first outlet 24A is the opening area of the first outlet 24A of the previous embodiments (shown in FIG. 2). Is set larger than. The opening / closing means 36 includes at least one shielding portion 37. The shielding portions 37 of this embodiment are formed in a plate shape, and a plurality of shielding portions 37 are arranged side by side along the opening surface of the first outlet 24A.

Each shielding portion 37 is arranged so as to be inclined with respect to the opening surface 38 of the first outlet 24A. In this embodiment, it is fixed so as to be tiltable around the horizontal axis. As a result, the opening / closing means 36 (plurality of shielding portions 37) of the present embodiment is configured as a louver.

The opening / closing means 36 of this embodiment can be brought into the first state of covering at least a part of the first outlet 24A by reducing the angle θ1 between the opening surface 38 of the first outlet 24A and the shielding portion 37. .. In this first state, the opening area of the first outlet 24A is set to be the same as the opening area of the first outlet 24A (shown in FIG. 2) of the first embodiment so far. In this first state, as in the previous embodiments, the air volume of the second outlet 24B can be increased until the second space 4 (shown in FIG. 1) reaches the target temperature. Therefore, the second space 4 Can be preferentially air-conditioned.

In the present specification, it is assumed that slight variations (errors) in manufacturing are allowed for "same" dimensions and the like. Further, the opening area of the first outlet 24A of this embodiment is obtained as the total value of the areas obtained by multiplying the separation distance L4 of the adjacent shielding portions 37, 37 and the distance L5 in the width direction of the first outlet 24A. Be done.

On the other hand, the opening / closing means 36 (shielding portion 37) of this embodiment exposes the first outlet 24A more than the first state by increasing the angle θ1 between the opening surface 38 of the first outlet 24A and the shielding portion 37. The second state (not shown) can be set. In this second state, the opening area of the first outlet 24A is set to be larger than the opening area of the first outlet 24A (shown in FIG. 2) of the first embodiment so far. In this second state, since the air volume to the first space 3 (shown in FIG. 1) can be increased before the second space 4 (shown in FIG. 1) reaches the target temperature, the first space 3 is set. It can be air-conditioned quickly.

The opening / closing means 36 is set to be switchable between a first state (shown in FIG. 7) and a second state (not shown). The switching between the first state and the second state may be performed manually by the resident, or may be performed by a driving means (not shown) that switches according to a signal from the control device 31.

By switching from the first state (shown in FIG. 7) to the second state (not shown), the opening / closing means 36 can, for example, move the first space 3 that has not been air-conditioned until immediately before the start of the air conditioning system 1. , Can be air-conditioned quickly. On the other hand, by switching the opening / closing means 36 from the second state to the first state, the second space 4 can be preferentially air-conditioned as in the conventional embodiments. Therefore, the opening / closing means 36 of this embodiment can control the temperatures of the first space 3 and the second space 4 according to the request of the resident.

In the chamber 12, when the opening / closing means 36 and the damper 30 are fully opened, the effective opening area of at least one second outlet 24B may be smaller than the effective opening area of the first outlet 24A. When a plurality of second outlets 24B and 24B are provided as in this embodiment, the effective opening area of each of the second outlets 24B and 24B is larger than the effective opening area of the first outlet 24A. Set small. Further, in this embodiment, the fully open opening / closing means 36 indicates a second state (not shown). Thereby, the air conditioning system 1 of this embodiment can effectively increase the air volume of the air conditioning air A4 to the first space 3.

In order to prevent the first outlet 24A from being covered more than in the first state, a stopper (not shown) may be provided to prevent the shielding portion 37 from tilting smaller than the angle θ1 in the first state. As a result, it is possible to prevent the air volume of the conditioned air A4 to the first space 3 from becoming smaller than necessary.

The opening / closing means 36 of the conventional embodiments has been exemplified by an embodiment in which the shielding portion 37 is inclined with respect to the opening surface 38 of the first outlet 24A, but the present invention is not limited to such an embodiment. FIG. 8 is a perspective view showing an example of the chamber 12 of still another embodiment of the present invention. In this embodiment, the same configurations as those in the previous embodiments are designated by the same reference numerals, and the description thereof may be omitted.

The opening / closing means 36 of this embodiment is composed of a shielding portion 37 that can slide along the opening surface 38 of the first outlet 24A. The shielding portion 37 of this embodiment is guided by an upper rail portion 39 provided on the upper side of the first outlet 24A and a lower rail portion 40 provided on the lower side of the first outlet 24A, and is guided by the first direction D1. It is configured to be slidable along.

By sliding the shielding portion 37, such an opening / closing means 36 exposes the first state (shown in FIG. 8) covering at least a part of the first outlet 24A and the first outlet 24A more than the first state. It is possible to switch to the second state (not shown).

In the first state, the opening area of the first outlet 24A exposed from the shielding portion 37 is set to be the same as the opening area of the first outlet 24A (shown in FIG. 2) of the first embodiment so far. As a result, in the first state, the air volume of the second outlet 24B can be increased as in the conventional embodiment, so that the second space 4 can be preferentially air-conditioned.

On the other hand, in the second state (not shown), the opening area of the first outlet 24A is set to be larger than the opening area of the first outlet 24A (shown in FIG. 2) of the conventional embodiments. As a result, in the second state, the air volume in the first space 3 can be increased, so that the first space 3 can be quickly air-conditioned. The switching between the first state and the second state may be performed by the resident by, for example, a handle 41 provided on the shielding portion 37, or a driving means that can be switched according to a signal from the control device 31 (not shown). ) May be used.

In order to prevent the first outlet 24A from being covered more than in the first state, it is desirable that the upper rail portion 39 and the lower rail portion 40 are terminated at the position of the shielding portion 37 in the first state. As a result, it is possible to prevent the air volume of the conditioned air A4 into the first space 3 from becoming small.

Although the particularly preferable embodiments of the present invention have been described in detail above, the present invention is not limited to the illustrated embodiments and can be modified into various embodiments.

An air conditioning system having the basic configuration shown in FIGS. 1 and 2 was installed in the building (Example). The chamber of the embodiment is provided with a first outlet that communicates with the first space without having a damper, and a second outlet that communicates with the second space via an air path having a damper. The second outlet is provided at the downstream end of the chamber in which the conditioned air flows in the first direction.

For comparison, an air conditioning system with dampers in both the air path communicating between the first outlet and the first space and the air path communicating between the second outlet and the second space It was installed in the building (Comparative Example 1). Further, an air conditioning system provided with both the first outlet and the second outlet at the downstream end in the first direction was installed in the building (Comparative Example 2). The first outlet of Comparative Example 2 communicates with the first space without having a damper, as in the embodiment.

The air conditioning (heating) in the building was performed for the air conditioning systems of Examples, Comparative Example 1 and Comparative Example 2. In the air conditioning system of the embodiment, air conditioning (heating) in the building was performed based on the procedure of FIG. Then, the temperatures of the first space (living room) and the second space (washroom) were measured, and it was verified whether or not the temperatures of those spaces could be controlled.

FIG. 9A is a graph showing the relationship between the temperature and time in the first space of the embodiment, and FIG. 9B is a graph showing the relationship between the temperature and time in the second space of the embodiment. be. FIG. 10 (a) is a graph showing the relationship between the temperature and time in the first space of Comparative Example 1, and FIG. 10 (b) shows the relationship between the temperature and time in the second space of Comparative Example 1. It is a graph. FIG. 11A is a graph showing the relationship between the temperature in the first space of Comparative Example 2 and time, and FIG. 11B is a graph showing the relationship between the temperature in the second space of Comparative Example 2 and time. It is a graph which shows.

As a result of the test, in the example, since the conditioned air can be discharged in the direction in which the first outlet intersects the first direction, the conditioned air can be discharged to the first space as compared with the comparative example 2 in which the first outlet is discharged along the first direction. It was possible to prevent the air volume of the conditioned air from increasing. As a result, the measured temperature in the second space of the example (shown in FIG. 9B) is closer to the target temperature than the measured temperature in the second space of Comparative Example 2 (shown in FIG. 11B). I was able to.

Further, in the embodiment, by reducing the air volume of the conditioned air to the second space with a damper, the decrease in the air volume of the conditioned air could be applied to the air volume of the conditioned air to the first space. As a result, as shown in FIG. 9A, the example was able to bring the measured temperature in the first space closer to the target temperature.

As described above, in the example (shown in FIGS. 9A and 9B), similarly to Comparative Example 1 (shown in FIGS. 10A and 10B) in which dampers are provided in all the air paths, the embodiment (shown in FIGS. 9A and 9B) is similarly used. I was able to control the temperature of the space inside the building. On the other hand, in the example, since the number of dampers can be reduced as compared with the comparative example 1, the initial cost of the air transport path can be reduced by 67%. Therefore, in the example, the temperature of the space in the building could be controlled while reducing the initial cost.
