Description

  The present invention relates to an air conditioning system for a two-family home.

  Conventionally, a two-family house in which a child household and a parent household coexist is known. In two-family homes, the privacy of each household is mutually secured by partitioning the living space where the child's household lives and the living space where the parent's household lives from each other. In addition, in a two-family house, in addition to the living space of each household, there may be a common space shared by each household.

  Patent Document 1 discloses a configuration in which a whole-house air conditioning system is provided in a two-family house provided with such a common space. The air conditioning system of Patent Document 1 includes two air conditioners, and the two air conditioners air-condition (cool and heat) a living space and a common space of each household. Specifically, in the air conditioning system of Patent Document 1, one of the two air conditioners (hereinafter referred to as the first air conditioner) performs air conditioning with the living space of the child household and the common space as the air conditioning target. The other air conditioner (hereinafter referred to as the second air conditioner) performs air conditioning with the living space of the parent household and the common space as the air conditioning target. According to this configuration, since the common space is included in the air conditioning targets of the first air conditioner and the second air conditioner, if any one of the air conditioners is in operation, air conditioning of the common space is performed. It is possible to do.

  Moreover, about the air conditioning system of patent document 1 in more detail, in the said air conditioning system, the 1st air conditioner and the 2nd air conditioner are each installed in the machine room adjacent to shared space.

  By the way, in the air conditioning system of Patent Document 1 described above, for example, when only the first air conditioner is in operation (i.e., one side operation), the air conditioning air supplied to the living space of the child household by the air conditioner is shared. It flows into the space and then flows (returns) to the machine room with the conditioned air supplied to the common space.

  Here, when the flow of air from such a common space to the machine room (as a result, to the air conditioner) occurs, the air in the living space of the parent household adjacent to the common space is drawn into the common space by the flow of air. There is a risk of In that case, since the air of the living space of the parent household drawn into the common space is air which is not air-conditioned (heated / heated) by the air conditioner, the air-conditioning efficiency may be lowered.

  This invention is made in view of the said situation, and makes it a main purpose to provide the air-conditioning system of the two-family residence which can suppress the fall of air-conditioning efficiency.

Further, the duct portion 92a is formed of, for example, expanded polystyrene such as polystyrene foam excellent in heat insulation performance, and its shape in plan view is square. The air conditioning duct 92 does not necessarily have to be configured to have a plurality of divided duct portions 92a, and may be configured by one elongated duct member.

  A blowout chamber 93 is connected to a side surface portion of the air conditioning duct 92 (specifically, the duct portion 92a). The blowout chambers 93 are provided at a plurality of locations in the air conditioning duct 92. In the blowout chamber 93, a blowout chamber 93a provided for the sanitary 45, a blowout chamber 93b provided for the bedroom 42, a blowout chamber 93c provided for the staircase upper space 74, and a shared living room 60 And a blowout chamber 93d provided for the These blowout chambers 93a to 93d are provided one by one for each of the spaces 42, 45, 60, and 74. The blowout chamber 93 d corresponds to a second blowout unit.

  Similar to the blowout chamber 83 of the first air conditioning system 80, the blowout chamber 93 is provided on the step wall portion 104 between the lowered ceiling 101 and the ceiling 102 of the normal height (see FIG. 5B). The blowout chamber 93 is provided in a state of being inserted into the opening 106 formed in the step wall portion 104. The blowout chamber 93 has a blowout port 94 for blowing out the conditioned air, and is provided in the step wall portion 104 in a state where the blowout port 94 is opened in a lateral direction.

  The conditioned air flowing through the air conditioning duct 92 is blown out to the sanitary 45, the bedroom 42, the stair space 74 and the shared living room 60 which are air conditioning targets from the blow out ports 94 of the respective blowing chambers 93a to 93d. Thus, the air conditioning (cooling and heating) of each of the spaces 42, 45, 60 and 74 is performed by the blown-out conditioned air.

  Further, in the blowout chamber 93d provided in the common living room 60, as in the case of the blowout chamber 83e, a plurality of (specifically, two) blowouts 94 are provided up and down. Air is blown out (see FIG. 5 (b)). On the other hand, although not shown, only one blowout port 94 is provided in the other blowout chambers 93a to 93c, and conditioned air is blown out from the one blowout port 94. However, a plurality of outlets 94 may be provided in these outlet chambers 93a to 93c.

Further, the conditioned air supplied to the bedroom 42 from the blowout chamber 93b flows into the hole 41 through the vent portion 53, and flows into the sanitary cavity 45 through the vent portion 57 together with the conditioned air flowing into the hole 41. Then, the conditioned air flowing into the sanitary 45 flows into the machine room 95 through the vent portion 98 together with the conditioned air supplied from the blowout chamber 93 a to the sanitary 45. Then, the air conditioner 91 takes in the air that has flowed into the machine room 95 and generates conditioned air. Thus, like the first air conditioning system 80, the second air conditioning system 90 is a circulation air conditioning system that performs air conditioning while circulating air in the house.

  Next, the installation configuration of the air conditioning ducts 82 and 92 and the blowout chambers 83 and 93 in the ceiling portion of the shared living room 60 will be described in detail.

  As shown in FIG. 4, the first air conditioning duct 82 extends from the first building portion 15 toward the shared living room 60 in the ceiling-to-ceiling space 103 on the lowered ceiling 101, and its end (downstream end) Is located above the shared living room 60. More specifically, the duct portion 82 a disposed at the end of the duct portions 82 a constituting the first air conditioning duct 82 is located above the shared living room 60. In the following, the duct portion 82a disposed at the end is referred to as a duct portion 108 in order to distinguish it from the other duct portions 82a. In this case, the duct portion 108 corresponds to the first end.

  On the other hand, the second air conditioning duct 92 extends from the second building part 16 toward the shared living 60 in the ceiling-to-ceiling space 103 on the lowered ceiling 101, and its end (downstream end) is the shared living 60 It is located above. More specifically, the duct portion 92 a disposed at the end of the duct portions 92 a constituting the second air conditioning duct 92 is located above the shared living room 60. In the following, the duct portion 92a disposed at the end is referred to as a duct portion 109 in order to distinguish it from the other duct portions 92a. In this case, the duct portion 109 corresponds to the second end.

  The duct portion 108 and the duct portion 109 are both disposed above the second floor space 60 a of the shared living room 60. The duct portions 108 and 109 are both disposed at the same position in the long side direction of the shared living room 60, and more specifically, disposed near the boundary with the shared balcony 18 in the shared living room 60. Moreover, each duct part 108,109 is mutually spaced apart and arrange | positioned in the short side direction of the common living 60, and, thereby, equipments, such as a ventilation installation, can be installed between each duct part 108,109. An installation space is formed. The blowout chamber 83 e is connected to the duct portion 108, and the blowout chamber 93 d is connected to the duct portion 109.

  As shown in FIG. 5, the lowered ceiling 101 described above is provided below the duct sections 108 and 109. The lowered ceiling 101 is provided straddling the duct portions 108 and 109, and is disposed over the entire area in the short side direction of the shared living room 60. Further, in the ceiling portion of the common living room 60, the step wall portion 104 connecting the lowered ceiling 101 and the ceiling 102 also extends over the entire short side direction of the common living room 60. The step wall portion 104 is disposed with its wall surface facing the side of the skip floor space 60b, and divides the back-to-ceiling space 103 and the common living room 60 from each other.

  In the step wall portion 104, the blowout chambers 83e and 93d are respectively provided. Each of the blowout chambers 83e and 93d is disposed with the blowout ports 84 and 94 directed to the skip floor space 60b. Therefore, conditioned air is blown out from the blowout chambers 83e and 93d toward the skip floor space 60b (in the long side direction of the shared living room 60). Further, these blowout chambers 83e and 93d are all disposed at the same height position, and more specifically, are disposed at positions symmetrical to each other with respect to the center line in the short side direction of the shared living room 60.

  According to the configuration of the embodiment described above, the following excellent effects can be obtained.

  The air conditioner 81 of the first air conditioning system 80 is provided in the first building unit 15, and the air conditioner 91 of the second air conditioning system 90 is provided in the second building unit 16. In this configuration, during single-sided operation in which only one of the air conditioners 81 and 91 is operating, the conditioned air supplied to the shared living 60 by the air conditioner 81 (91) in operation is the same as the living room. It flows from 60 to the building part 15 (16) where the air conditioner 81 (91) in operation is provided. In this case, the flow of air can be weaker than the flow of air from the common space to the air conditioner, which occurs in the configuration of the prior art (the technology of Patent Document 1). For this reason, it is possible to suppress the flow of the air from drawing the air in the other building part 16 (15) not operating the air conditioner into the common living 60, and as a result, the drawing of the air is performed. It is possible to suppress the decrease in air conditioning efficiency associated with the

  Since a part of the common living room 60 is a skip floor space 60 b having the lower floor portion 66, the common living room 60 can be made a space full of openness. Therefore, it becomes possible to plan communication of each household comfortably. Further, in the configuration in which the lower floor portion 66 is provided in the common living room 60, the air conditioning ducts 82, 92 are under the floor when the air conditioning air ducts 82, 92 are transported from the air conditioners 81, 91 to the living space and the common living room 60. If the air conditioning ducts 82, 92 need to be changed in the middle, the arrangement of the ducts 82, 92 may be complicated. In this respect, in the above embodiment, since the air conditioning ducts 82 and 92 are disposed not under the floor but in the ceiling, it is possible to dispose the air conditioning ducts 82 and 92 while avoiding such a problem.

  In any of the first air conditioning system 80 and the second air conditioning system 90, the blowout chambers 83e and 93d provided in the shared living room 60 are provided with a plurality (specifically, two) of outlets 84, 94 for the conditioned air. . In this case, even during single-sided operation in which only one of the air conditioning systems 80 and 90 (air conditioners 81 and 91) is operating, the conditioned air is blown out to the shared living room 60 from the plurality of outlets 84 and 94. Can. As a result, even during single-sided operation of the air conditioning systems 80 and 90, the shared living room 60 having the skip floor space 60b can be suitably air conditioned.

  The air conditioning ducts 82 and 92 are disposed in the ceiling space 103 above the lowered ceiling 101, and the duct portions 108 and 109 constituting the end portions of the air conditioning ducts 82 and 92 are respectively located above the shared living room 60 . And blowing chamber 83e, 93d is connected to the side part of each duct part 108, 109, and it blows out conditioned air from the each blowing chamber 83e, 93d in the long side direction (equivalent to the 2nd direction) of common living 60 did. In this case, the shared living room 60 having a rectangular shape in plan view can be suitably air-conditioned.

  The duct sections 108 and 109 of the air conditioning ducts 82 and 92 are disposed above the second floor space 60a, and conditioned air is directed to the skip floor space 60b from the blowout chambers 83e and 93d connected to the duct sections 108 and 109. I tried to blow it out. In this case, the skip floor space 60b having a large air volume can be suitably air-conditioned.

  Further, since the duct portions 108 and 109 of the air conditioning ducts 82 and 92 are disposed above the second floor floor space 60a, the ceiling 101 of the shared living room 60 is lowered relative to the ceiling portion of the second floor floor 60a. It is not necessary to arrange the lowered ceiling 101 at the ceiling portion of the skip floor space 60b. Thus, the air conditioning ducts 82 and 92 are disposed using the lowered ceiling 101, and the lowered ceiling 101 suppresses a decrease in the feeling of opening the shared living room 60 (specifically, the skip floor space 60b). be able to.

  In the configuration of the above embodiment in which the shared living room 60 is adjacent to the outdoor space and the shared balcony 18 (corresponding to the semi-outdoor space) on both sides in the housing depth direction (corresponding to the second direction), the shared living 60 in the housing depth direction There are no ceilings on which the air conditioning ducts 82 and 92 can be disposed on both sides of the housing. Therefore, it becomes practically impossible to blow out conditioned air from the side to the common living room 60, specifically, to blow conditioned air from the side in the depth direction of the house (that is, the long side direction of the common living room 60) . In that respect, in the above embodiment, in this configuration, the duct portions 108 and 109 are positioned above the shared living room 60, and the conditioned air is shared by the blowout chambers 83e and 93d connected to the duct portions 108 and 109. Since the configuration of blowing out in the long side direction is applied, it is possible to blow out the conditioned air in the shared living room 60 in the long side direction even with such a configuration.

  Even in a configuration in which shared living room 60 is adjacent to the outdoor space on both sides in the housing depth direction, and in a configuration adjacent to the semi-outdoor space on both sides in the housing depth direction, shared living 60 in the housing depth direction is Since there are no ceilings on which the air conditioning ducts 82 and 92 can be disposed on both sides of the sandwiching, air conditioning air can not be blown out from the side to the shared living room 60 in the long side direction. Therefore, the air-conditioning air may be blown out to the shared living room 60 in the long side direction by applying the above-described configuration to these configurations as well.

  The duct portions 108 and 109 of the air conditioning ducts 82 and 92 are disposed at the same position in the long side direction of the shared living 60, and the blowout chambers 83e and 93d connected to the duct portions 108 and 109 are short in the shared living 60 It arrange | positioned in the position which becomes mutually symmetrical with respect to the centerline of a side direction. In this case, even when one of the air conditioners 81 and 91 is operated on one side, the shared living room 60 can be air-conditioned in the same manner.

  The present invention is not limited to the above embodiment, and may be implemented, for example, as follows.

  (1) In the above embodiment, the duct portion 108 (first end portion) of the air conditioning duct 82 is positioned above the shared living 60, and the blowout chamber 83e is connected to the duct portion 108. Good. For example, the duct portion 108 may be omitted in the air conditioning duct 82, and the blowout chamber 83e may be connected to the duct portion 82a in front of the duct portion 108. In this case, since the duct portion 82a is disposed in the first building portion 15, it is conceivable that the blowout chamber 83e connected thereto is disposed to blow out the conditioned air, for example, in the short side direction of the shared living room 60.

  Further, similarly to this, also in the air conditioning duct 92, the duct portion 109 may be omitted, and the blowout chamber 93d may be connected to the duct portion 92a in front of the duct portion 109.

  (2) In the above embodiment, in the first air conditioning system 80, the plurality of outlets 84 are provided in one blowout chamber 83e provided in the common living room 60, but this is changed to one blow in the common living room 60. A plurality of blowout chambers 83 having an outlet 84 may be provided. Also in this case, since the plurality of outlets 84 for blowing out the conditioned air can be provided in the common living room 60, the common living room 60 can be suitably air-conditioned even during one-sided operation of the air conditioner 81. Similarly, in the second air conditioning system 90 as well, a plurality of blowout chambers 93 having one blowout port 94 may be provided in the common living room 60.

  (3) In the above embodiment, the air conditioning ducts 82 and 92 are disposed in the ceiling underfloor space 103 of the second floor portion 12, but the air conditioning ducts 82 and 92 are changed, and the floor floor space of the second floor portion 12 (in other words, the first floor portion 11 and the second floor) An air conditioning duct may be provided in the space between the floor 12 and the floor 12). In that case, the blowout chamber is provided on the floor side, and conditioned air is blown out from the blowout chamber on the floor side. However, in the configuration of the above embodiment, since the floor height is different between the shared living room 60 to which the air conditioning ducts 82 and 92 supply air-conditioned air and the other space, the air conditioning duct is located under the floor. If it is going to arrange, it will be necessary to change the height of an air-conditioning duct in the middle, for example, there is a possibility that the arrangement aspect of a duct may become complicated. Therefore, in view of this point, it may be desirable to dispose the air conditioning duct in the space 103 behind the ceiling.

  (4) In the above embodiment, the machine room 85 of the air conditioner 81 is provided adjacent to the LDK space 35, but may be provided at another position, for example, provided adjacent to the hole 31 . In short, the machine room 85 should just be provided in the second floor part 12 of the 1st building part 15. As shown in FIG.

  In the above embodiment, the machine room 95 of the air conditioner 91 is provided adjacent to the sanitary 45, but may be provided at another position, for example, provided adjacent to the hole 41 or the bedroom 42. Good. In short, the machine room 95 may be provided on the second floor portion 12 of the second building part 16.

  (5) In the above embodiment, a part of the shared living room 60 is the skip floor space 60b, and a part of the remaining living space is the second floor floor space 60a. However, the entire shared living room 60 may be the skip floor space by changing this. Good. In that case, the shared living room 60 can be made a space more full of a sense of openness. In addition, the entire shared living room 60 may be the second floor space 60a. In that case, the number of outlets 84, 94 of the blowout chambers 83e, 93d provided in the shared living room 60 may be one.

  The shared space to be air-conditioned does not have to be the shared living room 60, and may be another shared space such as a shared dining room or entrance hall.

  (6) In the said embodiment, although the air-conditioning system of this invention was applied to the two-family house 10 which has the intermediate building part 17 (shared living 60) between the 1st building part 15 and the 2nd building part 16, The present invention may be applied to a two-family house 10 having a configuration other than the above. For example, it is conceivable that the present invention is applied to a configuration in which the shared living room 60 is provided straddling the building portions 15 and 16 on the back side of the first building portion 15 and the second building portion 16. In short, as long as the shared living room 60 is provided adjacent to the first building part 15 and the second building part 16, the air conditioning system of the present invention can be applied.
