Description

The present invention relates to a ceiling chamber is partitioned and formed to the indoor space by the ceiling panel having a large number of through holes, formed by arranging the air supply port for blowing out the return air inlet and the air conditioning air taking in return air The present invention relates to an air-conditioning system including an air-conditioning device and air-conditioning the indoor space by exuding air-conditioning air from a through hole of the ceiling panel into the indoor space.

As a conventional air conditioning system, a system is known in which air conditioning air after cooling or heating is supplied from an air conditioner to a ceiling chamber partitioned from an indoor space by a ceiling panel (see Patent Document 1).
In such a conventional air-conditioning system, a large number of through holes are dispersedly formed in the ceiling panel, and the conditioned air filling the ceiling chamber is configured to flow out into the indoor space through these many through holes. There is. Hereinafter, this outflow state may be expressed as "exuding" or the like. As a result, the indoor space is conditioned by the convection of the conditioned air exuding from a large number of through holes.

Further, in the air conditioning system described in Patent Document 1, a return air port for taking in return air and cooling air as air conditioning air are blown into the ceiling chamber (A) partitioned from the indoor space (B) by the ceiling panel (16). An air conditioner (14) is provided in which an air supply port for discharging air is arranged. With this configuration, the air conditioner (14) can take in the air of the ceiling chamber as return air, cool or heat it, and supply the cooled or heated air to the ceiling chamber (A) as air conditioning air (A). See FIG. 1 and the like in Patent Document 1).

During the heating operation of the air conditioning system described in Patent Document 1, the warm air supplied from the air conditioner (14) to the ceiling chamber (A) is formed on the ceiling panel (16) because its specific gravity is smaller than that of the indoor air. It stays in the ceiling chamber (A) without flowing out to the indoor space (B) through the through holes (16a, 16b). Therefore, the indoor space is heated by the heat radiation (G) of the ceiling panel heated by the retained warm air (see FIG. 6 and paragraph 0031 of Patent Document 1).
On the other hand, during the cooling operation of the air conditioning system described in the same document, the cold air supplied from the air conditioner (14) to the ceiling chamber (A) rises from the indoor space through the through hole because its specific gravity is larger than that of the indoor air. An amount (E) commensurate with the indoor air (G) will flow out from the ceiling chamber into the indoor space (B) through the through hole (see FIG. 2 and paragraph 0030 of Patent Document 1).

An embodiment of the present invention will be described with reference to the drawings.

In the air-conditioning system of the present embodiment (hereinafter referred to as “the main air-conditioning system”), as shown in FIG. 1, the air-conditioning device 10 is arranged in the ceiling chamber 1 partitioned by the ceiling panel 30 with respect to the indoor space 2. It is composed of.

That is, the ceiling chamber 1 is formed as a space partitioned from the indoor space 2 by the ceiling panel 30 which is laid separately below the slab 40 on the upper floor and constitutes the ceiling surface of the indoor space 2. The air conditioner 10 is configured as a so-called package type air conditioner having a return air port 12 for taking in the return air RA and an air supply port 11 for blowing out the air conditioning air SA after cooling or heating. The air port 12 and the air supply port 11 are arranged in the ceiling chamber 1 and supported on the lower surface of the slab 40 with respect to the ceiling chamber 1.

In the air conditioner 10, the return air port 12 is provided so as to open downward on the bottom surface of the main body, while air is supplied so as to open diagonally outward and downward at the boundary between the outer periphery of the bottom surface of the main body and the peripheral side surface of the main body. A mouth 11 is provided. Then, the air conditioner 10 takes in the air of the ceiling chamber 1 as the return air RA from the return air port 12, and heat exchanges the taken in return air RA with the refrigerant circulated between the outdoor unit (not shown). The air-conditioned air SA that has been cooled or heated is supplied from the air supply port 11 to the ceiling chamber 1.

By installing the air conditioning device 10 in the ceiling chamber 1 in this way, the air conditioning air SA is supplied to the ceiling chamber 1 from the air supply port 11 of the air conditioning device 10, and the ceiling chamber 1 is filled with the air conditioning air SA. As a result, the ceiling panel 30 is cooled or heated by contact with the air-conditioning air SA supplied to the ceiling chamber 1 to absorb or radiate heat to the indoor space 2, and the heat absorption or heat radiation causes the ceiling panel 30 to absorb or radiate heat. The indoor space 2 will be air-conditioned. The material of the ceiling panel 30 can be appropriately selected, such as a metal that is cooled or heated by contact with the conditioned air SA and can satisfactorily absorb heat or radiate heat. Materials can be selected as appropriate.

Further, a large number of through holes 30a are dispersedly formed in the ceiling panel 30. The conditioned air SA supplied to the ceiling chamber 1 seeps out into the indoor space 2 as exuded air SA1 through these many through holes 30a. Then, the indoor space 2 is also air-conditioned by the convection of the exuded air SA1 exuded from these many through holes 30a.

On the wall surface of the indoor space 2, in addition to various setting operations such as setting temperature and mode switching of the air conditioning system, operation for performing output control of the air conditioner 10 based on the measured temperature of the indoor space 2 and other operation control. A control device 20 is provided. The installation location of the operation control device 20 can be changed as appropriate, such as being built in the air conditioner 10 or being installed in a management room or the like separate from the indoor space 2.

In this air conditioning system, as shown in FIG. 1, as a blower 25 capable of blowing air between the ceiling chamber 1 and the outside thereof, a perimeter capable of blowing air between the ceiling chamber 1 and the perimeter zone 2a (an example of the outside). An underfloor chamber blower 25A capable of blowing air between the ceiling chamber 1 and the underfloor chamber 4 (an external example) is provided.

The perimeter zone 2a indicates a space close to the window W in the indoor space 2, and a perimeter blower 25A is installed in a portion of the ceiling panel 30 corresponding to the ceiling portion facing the perimeter zone 2a.
On the other hand, the underfloor chamber 4 shows a space partitioned from the indoor space 2 by the floor panel 35, and the underfloor chamber blower 25B is connected to the portion of the ceiling panel 30 communicating with the underfloor chamber 4 through the vertical air passage 3. Is installed. Further, the vertical air passage 3 can be configured as an air passage constructed by a vertical duct provided along the wall surface of the indoor space 2, but in the present embodiment, the wall of the indoor space 2 has a double wall structure. The space formed inside the space is used as the vertical air duct 3.

Then, the operation control device 20 controls the operation of these blowers 25 to appropriately perform the air conditioning of the perimeter zone 2a and the air conditioning of the floor panel 35 side.
The air conditioning load of the perimeter zone 2a is high, such as when the perimeter zone 2a becomes high in temperature due to sunlight from the window W during cooling, or when the perimeter zone 2a becomes low in temperature due to heat transfer from the window W during heating. In this case, the operation control device 20 blows the air from the perimeter blower 25A toward the perimeter zone from the ceiling chamber 1 toward the perimeter zone 2a (in FIG. 1, the air is blown from the perimeter blower 25A in the direction of the solid line arrow). The operation of the perimeter blower 25A is controlled. Then, the conditioned air SA supplied from the air conditioner 10 to the ceiling chamber 1 is supplied to the perimeter zone 2a through the perimeter blower 25A, and the perimeter zone 2a is appropriately air-conditioned.

On the other hand, when the air-conditioning load on the floor side of the indoor space 2 is high, such as when the feet are cold during heating or when the feet are not sufficiently cooled during cooling, the operation control device 20 is a blower for the underfloor chamber. The operation of the underfloor chamber blower 25B is set as the blower state of 25B as the blower state toward the underfloor chamber from the ceiling chamber 1 to the underfloor chamber 4 (the state in which the blower is blown from the underfloor chamber blower 25B in the direction of the solid line arrow in FIG. 1). Take control. Then, the conditioned air SA supplied from the air conditioner 10 to the ceiling chamber 1 is supplied to the underfloor chamber 4 through the underfloor chamber blower 25B and the vertical air passage 3. Then, the floor panel 35 is cooled or heated by heat exchange with the supplied conditioned air SA, and the floor surface side of the indoor space 2 is appropriately heated by heat absorption or heat radiation of the cooled or heated floor panel 35. It will be air-conditioned. Further, the floor panel 35 is formed with a perimeter vent 37 located on the floor facing the perimeter zone 2a, a vent 36 located on the floor facing the other indoor space 2, and the like. Then, the conditioned air SA supplied to the underfloor chamber 4 flows out to the perimeter zone 2a and other indoor spaces 2 through these vents 36 and 37, and the outflow of the conditioned air SA also causes the perimeter zone 2a and Air conditioning on the floor side of the other indoor space 2 will be appropriately performed.

The above is the basic configuration of the air conditioning system. In the air conditioning system, the amount of exuded air SA1 from the through hole 30a of the ceiling panel 30 into the indoor space 2 is determined based on the indoor temperature of the indoor space 2. It has a configuration for appropriately adjusting based on the recognized air conditioning load and the setting operation for the operation control device 20 by the user, and the details of the configuration will be described below.

As shown in FIG. 2, the operation control device 20 changes the blowing state of these blowers 25 by executing a predetermined program, and the exuded air that seeps out from the through hole 30a of the ceiling panel 30 into the indoor space 2. It is configured to function as a seepage amount adjusting means 21 capable of adjusting the seepage amount of SA1.

The exudation amount adjusting means 21 sets the air blowing state of the blower 25 to a non-air blowing state for the ceiling chamber that does not blow air from the perimeter zone 2a or the underfloor chamber 4 to the ceiling chamber 1, and a non-blowing state for the ceiling chamber from the perimeter zone 2a or the underfloor chamber 4 to the ceiling chamber. It switches between the air blowing state for the ceiling chamber and the air blowing state for blowing air toward 1. Then, by switching the blowing state of the blower 25 in this way, the amount of seepage air SA1 that seeps out from the through hole 30a of the ceiling panel 30 into the indoor space 2 can be changed.

Here, the non-blowing state for the ceiling chamber is a state in which the air is blown to the outside from the ceiling chamber 1 as in the above-mentioned blowing state for the perimeter zone and the blowing state for the underfloor chamber (direction of the solid arrow in FIG. 1). In addition to the state in which the air is blown (downward), the state in which the air is stopped is included. On the other hand, the air blowing state toward the ceiling chamber is the air blowing state in which the air blowing direction is reversed from the air blowing state toward the perimeter zone and the air blowing state toward the underfloor chamber (the state in which the air is blown in the direction of the broken line arrow (upward) in FIG. 1). Become.

Then, when the blowing state of the blower 25 is switched from the non-blowing state facing the ceiling chamber to the blowing state facing the ceiling chamber, air flows into the ceiling chamber 1 from the outside through the blower 25, and the internal pressure of the ceiling chamber 1 is increased. It will rise. Due to the increase in the internal pressure of the ceiling chamber 1, the amount of exuded air SA1 from the through hole 30a of the ceiling panel 30 into the indoor space 2 increases, and as a result, the air conditioning of the indoor space 2 becomes the air conditioning of the perimeter zone 2a. And the air conditioning on the floor panel 35 side will be prioritized.

On the contrary, when the blowing state of the blower 25 is switched from the blowing state facing the ceiling chamber to the non-blowing state facing the ceiling chamber, air flows out from the ceiling chamber 1 through the blower 25, and the internal pressure of the ceiling chamber 1 is increased. Decreases. Due to the decrease in the internal pressure of the ceiling chamber 1, the exuding amount of the exuding air SA1 is reduced, or the exuding of the exuding air SA1 is stopped, and as a result, the air conditioning of the perimeter zone 2a as described above is performed. The air conditioning on the floor panel 35 side is prioritized over the air conditioning on the indoor space 2.

Further, when a plurality of blowers 25 capable of blowing air between the ceiling chamber 1 and the outside thereof are provided, the seepage amount adjusting means 21 changes the blowing state of at least a part of the blowers 25 to penetrate the ceiling panel 30. It is also possible to adjust the amount of exudation of the exuding air SA1 from the hole 30a into the indoor space 2.
For example, when the air blowing state of some of the blowers 25 is the air blowing state toward the ceiling chamber and the other blowers 25 are not the air blowing state toward the ceiling chamber, the total amount of air blown by the blowers 25 in the ceiling chamber facing state. However, when the total amount of air blown by the blower 25 in the non-blower state for the ceiling chamber is exceeded, the exuding air SA1 from the through hole 30a of the ceiling panel 30 into the indoor space 2 is exuded. Then, in this state, the internal pressure of the ceiling chamber 1 can be changed by changing the blowing state such as the blowing direction and the blowing amount of at least a part of the blowers 25 by the seepage amount adjusting means 21. The amount of exuded air SA1 can be increased or decreased.

For example, the underfloor chamber while air-conditioning the perimeter zone 2a with the perimeter blower 25A being blown toward the perimeter zone (the state in which the perimeter blower 25A is blowing air from the perimeter blower 25A in the direction of the solid arrow (downward)). The air blowing state of the air conditioner 25B is defined as the air blowing state toward the ceiling chamber (the state in which the air is blown from the underfloor chamber blower 25B in the direction of the broken line arrow (upward) in FIG. 1). In this case, if the amount of air blown to the ceiling chamber 1 by the underfloor chamber blower 25B is larger than the amount of air blown to the perimeter zone 2a by the perimeter blower 25A, the air flow from the through hole 30a of the ceiling panel 30 to the indoor space 2 The exudation of the exuding air SA1 can be generated. Then, in this state, the exuding amount adjusting means 21 reduces the amount of air blown by the perimeter blower 25A or increases the amount of air blown by the underfloor chamber blower 25B to increase the amount of exuded air SA1. It can be increased, and conversely, the amount of exuded air SA1 is decreased or the amount of exuded air SA1 is decreased in the form of increasing the amount of air blown by the perimeter blower 25A or decreasing the amount of air blown by the underfloor chamber blower 25B. The exudation of the exuding air SA1 can be stopped.

Further, the air conditioner on the floor side of the indoor space 2 is set to the state in which the underfloor chamber blower 25B is blown toward the underfloor chamber (the state in which the air is blown from the underfloor chamber blower 25B in the direction of the solid arrow (downward) in FIG. 1). The air conditioner of the perimeter blower 25A is set to the ceiling chamber direction blower state (a state in which air is blown from the perimeter blower 25A in the direction of the broken line arrow (upward) in FIG. 1). In this case, if the amount of air blown to the ceiling chamber 1 by the perimeter blower 25A is larger than the amount of air blown to the underfloor chamber 4 by the underfloor chamber blower 25B, the air flow from the through hole 30a of the ceiling panel 30 to the indoor space 2 The exudation of the exuding air SA1 can be generated. Then, in this state, the exuding amount adjusting means 21 reduces the amount of air blown by the underfloor chamber blower 25B or increases the amount of air blown by the perimeter blower 25A, thereby increasing the amount of exuded air SA1. It can be increased, and conversely, the amount of exuded air SA1 is decreased or exuded in a form of increasing the amount of air blown by the underfloor chamber blower 25B or decreasing the amount of air blown by the perimeter blower 25A. The exudation of the exuding air SA1 can be stopped.

Although not shown, the outside air is introduced into the ceiling chamber 1, and the amount of the outside air introduced is calculated from the amount of air blown to the perimeter zone 2a by the perimeter blower 25A and the amount of air blown to the underfloor chamber 4 by the underfloor chamber blower 25B. It is also possible to generate exudation of the exuding air SA1 from the through hole 30a of the ceiling panel 30 into the indoor space 2 by increasing the size. In this case, the exuding amount adjusting means 21 changes the blowing state of each blower 25 while considering the amount of outside air introduced to raise or lower the internal pressure of the ceiling chamber 1, thereby increasing or decreasing the internal pressure of the ceiling chamber 1 from the through hole 30a of the ceiling panel 30 to the room. The amount of exuding air SA1 to the space 2 can be changed.

The operation control device 20 of this air conditioning system uses the heat of the air conditioning air SA supplied from the air conditioning device 10 to the ceiling chamber 1 to the slab on the upper floor during a time when the air conditioning load of the indoor space 2 is small, such as at night. It is configured to appropriately operate in the skeleton heat storage mode in which heat is stored in the skeleton of a building such as 40.
In this skeleton heat storage mode, the operation of the air conditioner 10 is continued while stopping the operation of the perimeter blower 25A and the underfloor chamber blower 25B. As a result, the heat of the conditioned air SA supplied from the air conditioner 10 to the ceiling chamber 1 is stored in the skeleton such as the slab 40 facing the ceiling chamber 1, and the heat stored in the skeleton in this way is stored. However, as the air-conditioning load of the indoor space 2 increases, it is radiated to the indoor device, so that it is used as an auxiliary for the air-conditioning of the indoor space 2.

Further, as shown in FIG. 3, the air conditioner 10 is driven by swinging a horizontal flap 15 formed so as to extend outward from the edge of the air supply port 11 on the return air port 12 side around the horizontal axis. A wind direction variable mechanism 16 including an actuator capable of changing the blowing direction of the conditioned air SA at the air supply port 11 is provided. Further, the horizontal flap 15 has a "dogleg" shape that further bends outward at the intermediate portion in the extending direction from the edge portion of the air supply port 11 on the return air port 12 side toward the tip portion.
Then, in the above-mentioned skeleton heat storage mode, the horizontal flap 15 is set to the upward swinging posture (the posture shown in FIG. 3), so that the conditioned air SA blown out from the air supply port 11 is of the horizontal flap. It circulates along the upper surface and is sprayed on the lower surface of the slab 40 on the upper floor. As a result, the heat of the conditioned air SA can be efficiently stored in the slab 40.
