Description

The present invention relates to an air conditioning system in a building containing multiple indoor spaces.

Background Art Conventionally, there has been proposed a central air-conditioning system in which a common air conditioner controls the temperature of a plurality of indoor spaces in a building. In a central air-conditioning system, for example, air whose temperature has been adjusted by an air conditioner installed in a machine room or the like is supplied to a plurality of indoor spaces through a plurality of ducts.

For example, Japanese Patent Application Laid-Open No. 2013-133945 (Patent Document 1) discloses an air conditioning system for air conditioning a plurality of living rooms and non-living rooms. In this air-conditioning system, a branch duct leading to the machine room is installed in the duct connected to the non-living room, and by supplying temperature-controlled air to the machine room immediately after the air conditioning starts, the efficiency of the air conditioner is improved. A technique to do so has been proposed.

In addition, in Japanese Patent Application Laid-Open No. 4-55653 (Patent Document 2), according to the temperature difference between the temperature of each indoor space and the set temperature, the opening of the damper provided at each outlet is adjusted and controlled. A method of controlling a harmonizing device has been proposed.

JP 2013-133945 A JP-A-4-55653

In the air conditioning system of Patent Document 1, air outlets are provided not only in living rooms but also in non-living rooms of a house, and after a certain period of time has elapsed from the start of air conditioning, temperature-controlled air is supplied to non-living rooms.

In summer, the temperature of living rooms and non-living rooms on the top floor of a house is higher than that of the first floor (lower floor). Therefore, by supplying temperature-controlled air (cold air) to the non-living rooms on the top floor, the temperature environment of the non-living rooms on the top floor can be improved. However, in the air conditioning system of Patent Document 1, the non-living room is air-conditioned in conjunction with the air conditioning of the living room both during cooling and during heating, so there is room for improvement from the viewpoint of reducing the air conditioning load.

Further, in the control method of Patent Document 2, a damper is required for each outlet provided in the indoor space to be air-conditioned. Also, each damper must be individually electronically controlled. Therefore, in the air conditioning system as disclosed in Patent Document 2, the size of the air conditioner itself is increased and the number of parts is increased, which poses problems of increased cost and increased power consumption.

The present invention has been made to solve the above-described problems, and its object is to improve the temperature environment of indoor spaces such as non-living rooms in houses without increasing power consumption. It is to provide an air conditioning system that can

An air-conditioning system according to one aspect of the present invention is an air-conditioning system for a building including a first indoor space and a second indoor space, comprising an air conditioner for adjusting the temperature of intake air, and temperature adjustment by the air conditioner. A first outlet for blowing the air after being adjusted to the first indoor space, a second outlet for blowing the air whose temperature has been adjusted by the air conditioner to the second indoor space, and the first outlet and the second outlet. and an opening adjustment mechanism provided at least one of the outlets for adjusting the opening of the outlet. The opening adjustment mechanism includes a shape-changing member whose shape changes according to the temperature of the air in the indoor space, and a position-changing member whose position changes according to the shape change of the shape-changing member, thereby changing the opening. .

Preferably, the opening adjustment mechanism is provided for both the first outlet and the second outlet. In this case, it is desirable that the shape-changing member at the first outlet and the shape-changing member at the second outlet have different temperature zones in which the shape changes.

Typically, the first indoor space is a living room and the second indoor space is a non-living room.

It is desirable that the minimum state of the degree of opening of the first outlet adjusted by the degree-of-opening adjustment mechanism provided in the first outlet is an open state between fully closed and fully open. On the other hand, it is desirable that the minimum state of the degree of opening of the second outlet adjusted by the degree-of-opening adjustment mechanism provided in the second outlet is the fully closed state.

The first indoor space and the second indoor space may be non-residential rooms located on different floors. In this case, the opening degree adjustment mechanism provided for the first outlet and the opening degree adjustment mechanism provided for the second outlet are such that when the first outlet is fully open, the second outlet is fully opened. It may be configured such that when it is in a closed state and the first outlet is in a fully closed state, the second outlet is in a fully open state.

Preferably, the degree-of-opening adjustment mechanism includes a windbreak member for preventing the temperature-adjusted air from hitting the shape-changing member.

The shape-changing member is typically a shape memory alloy, but may be a bimetal or a piezoelectric element.

According to the present invention, since the opening degree of the air outlet is adjusted by the opening degree adjusting mechanism including the shape-changing member, the temperature environment of an indoor space such as a non-living room in a house can be improved without increasing power consumption. be able to.

An embodiment of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are denoted by the same reference numerals, and the description thereof will not be repeated.

In the present embodiment, an air-conditioning system for air-conditioning a plurality of indoor spaces provided on the top floor (for example, the second floor) of a house will be described. The “indoor space” is a space defined by an outer wall, a partition wall, or the like, and includes living rooms and non-living rooms. A “living room” is a space that is regularly used by a resident, and includes a living room, a dining room, a private room (including a bedroom), and the like. A “non-living room” is a space used by a resident on a non-regular basis, and includes at least a corridor and an entrance that serve as passages between rooms. The non-living room may further include a washroom, a closet, and the like.

(About overview)
First, prior to describing the air conditioning system according to the present embodiment, a general known air conditioning system 101 will be briefly described with reference to FIGS. 13 and 14. FIG.

A known air conditioning system 101 provides air conditioning for the second floor portion 90 of the residence. In the second floor portion 90 of the house, private rooms 91 to 93, which are a plurality of living rooms partitioned by outer walls and partition walls, and corridors 94, which are non-living rooms adjacent to these private rooms 91 to 93, are arranged.

The air conditioning system 101 includes, for example, one air conditioner 102 provided in the attic space, air outlets 131 to 133 provided in the private rooms 91 to 93, respectively, and ducts connecting the air conditioner 102 and the air outlets 131 to 133, respectively. 121-123.

Air conditioner 102 is an air conditioner capable of both cooling operation and heating operation. A single remote control 111 is used to turn on/off the power of the air conditioner 102, select an operation mode, set the temperature of the air conditioner, and the like. Remote controller 111 is provided on the wall surface of private room 91, for example.

The air conditioner 102 adjusts the temperature of the taken air according to the set temperature set by the remote controller 111 . The air after the temperature adjustment is sent to outlets 131-133 via ducts 121-123, and is blown out from the outlets 131-133 into the private rooms 91-93. Each of the outlets 131 to 133 is not provided with an opening degree adjusting mechanism, which will be described later, and air after temperature adjustment is blown out from the outlets 131 to 133 at the same air volume.

In the known air conditioning system 101, the corridor 94 is not provided with an air outlet. In summer, the second floor is more affected by solar radiation than the first floor, so the room temperature on the second floor is higher than the room temperature on the first floor. Therefore, the second-floor corridor 94 in midsummer is extremely hot, creating a severe temperature environment.

Therefore, the air-conditioning system according to the present embodiment is designed to improve the comfort of the second-floor corridor 94 in the summer by providing an outlet in the second-floor corridor 94 as well.

FIG. 1 is a plan view schematically showing the schematic configuration of an air conditioning system 1 according to this embodiment. FIG. 2 is a diagram conceptually showing the air conditioning system 1 according to the present embodiment. The air conditioning system 1 air-conditions the second floor portion 90 of the residence including the private rooms 91 to 93 and the corridor 94 in the same manner as the well-known air conditioning system 101 .

The air conditioning system 1 includes one air conditioner 2 for adjusting the temperature of the sucked air, first outlets 31 to 33 provided in the private rooms 91 to 93, respectively, and a second outlet provided in the corridor 94. It has an air outlet 34 and ducts 21 to 24 connecting the air conditioner 2 and these air outlets 31 to 34, respectively. As described above, the air conditioning system 1 is significantly different from the known air conditioning system 101 in that the air after temperature adjustment by the air conditioner 2 is also blown out to the corridor 94 .

The air conditioner 2 is installed in a place different from the private rooms 91 to 93 and the corridor 94 to be air-conditioned, for example, in an attic space. The place where the air conditioner 2 is installed may be an underfloor space, a wall space, or the like, or may be a machine room provided separately.

The first outlets 31-33 are provided, for example, on the ceilings of the private rooms 91-93, respectively. The second outlet 34 is provided on the ceiling of the corridor 94, for example.

Here, in the present embodiment, each of the outlets 31 to 34 is provided with an opening adjustment mechanism. Specifically, opening adjustment mechanisms 41 to 43 are provided for the first outlets 31 to 33 respectively, and an opening adjustment mechanism 44 is provided for the second outlet 34 . In the following description, the opening adjustment mechanism provided for each first outlet is referred to as the "first opening adjustment mechanism", and the opening adjustment mechanism provided for the second outlet is referred to as the "second opening adjustment mechanism". Also called an adjustment mechanism.

The first opening adjustment mechanisms 41 to 43 adjust the opening of the first outlets 31 to 33, respectively, and the second opening adjustment mechanism 44 adjusts the opening of the second outlet 34. . As a result, the first opening adjustment mechanisms 41 to 43 adjust the amount of air blown to the private rooms 91 to 93, respectively, and the second opening adjustment mechanism 44 adjusts the amount of air blown to the corridor 94. is adjusted.

(Concerning the configuration example of the first opening adjustment mechanism)
Configuration examples of the first opening adjustment mechanisms 41 to 43 will be described with reference to FIGS. 3 to 6. FIG. 3 to 6 representatively show the configuration of the opening adjustment mechanism 41 provided at the outlet 31 of the private room 91, but the outlets 32 and 33 of the other private rooms 92 and 93 are provided. The opening adjustment mechanisms 42 and 43 have the same configuration.

Referring to FIG. 3, the first opening adjustment mechanism 41 includes a shape-changing member 51 whose shape changes according to the temperature of the air in the private room 91, and a position which changes according to the shape change of the shape-changing member 51. and a position changing member 52 that changes the degree of opening of the first blowout port 31 thereby.

Shape-changing member 51 is typically a shape memory alloy. The shape-changing member 51 changes its length according to the temperature of the air in the private room 91 . Specifically, the shape-changing member 51 expands when it reaches a predetermined temperature or higher, and its length changes according to the temperature. The predetermined temperature at which shape-changing member 51 begins to react is 26° C., for example. Hereinafter, the state below the predetermined temperature is referred to as "initial state", and the state above the predetermined temperature is referred to as "reaction state".

The shape-changing member 51 is attached to the frame or the like of the outlet 31 by an attachment member 56 . The shape-changing member 51 is provided at a position that does not overlap the openings 31a to 31c of the outlet 31 in plan view. As a result, it is possible to prevent the temperature-adjusted air from being directly blown onto the shape-changing member 51 from above.

The position-changing member 52 is engaged with or connected to the shape-changing member 51 so that its own position is changed according to the shape change of the shape-changing member 51 . In the present embodiment, the position changing member 52 includes, for example, an advancing/retreating member 53 having an engaging surface 53a that contacts the distal end portion of the shape-changing member 51, and a plurality of opening/closing members 54 fixed to the advancing/retreating member 53. .

The advance/retreat member 53 advances/retreats in a direction crossing the length direction of the shape-changing member 51 . The engaging surface 53a is an inclined surface provided at the distal end of the retractable member 53. As shown in FIG. A spring 55 is provided at the rear end of the retractable member 53 to bias the retractable member 53 toward the shape-changing member 51 .

The blowout port 31 has a plurality of openings 31a to 31c spaced apart from each other, and each of the openings 31a to 31c extends along the direction intersecting the retractable member 53. As shown in FIG. The opening/closing member 54 is provided for each of the openings 31a to 31c and extends along the length direction of the openings 31a to 31c, that is, along the direction intersecting the advance/retreat member 53. As shown in FIG. The plurality of opening/closing members 54 are arranged at intervals along the length direction of the retractable member 53 . The openings 31a to 31c are opened and closed according to the position of the opening/closing member .

3 and 4 schematically show the opening degree of the first outlet 31 when the shape-changing member 51 is in the initial state. 5 and 6 schematically show the opening degree (maximum opening degree) of the first outlet 31 when the shape-changing member 51 is in the reaction state.

When the shape-changing member 51 is in the initial state, the openings 31a to 31c of the first outlet 31 are half closed by the opening/closing member . That is, in the initial state, the first outlet 31 is in a half-open state.

In summer, when the room temperature of the private room 91 reaches 26° C. or higher, the shape-changing member 51 begins to stretch. As the shape-changing member 51 extends, the retractable member 53 is pushed toward the spring 55 and retracts. When the advancing/retracting member 53 retreats, the plurality of opening/closing members 54 move parallel in the direction of widening the opening degree of the first outlet 31 . In this manner, the position of the position-changing member 52 is changed according to the shape change of the shape-changing member 51 .

Although the opening degree of the first outlet 31 is changed by displacing (moving) the opening/closing member 54 of the position changing member 52, it is not limited to this. It may be realized by changing the (angle).

5 and 6 show the position of the opening/closing member 54 when the first outlet 31 is fully opened. The opening/closing member 54 in the first opening adjustment mechanism 41 has a half-open position (the position shown in FIGS. 3 and 4) in which the first outlet 31 is half-opened, and a fully-open state in which the second outlet 32 is opened. It displaces between the fully open position (the position shown in FIGS. 5 and 6). In the present embodiment, first opening adjustment mechanism 41 is configured such that first outlet 31 is fully opened when the room temperature of private room 91 is, for example, 30° C. or higher.

Note that, as shown in FIG. 10 , the first opening adjustment mechanism 41 includes a windbreak for preventing the temperature-adjusted air blown from the first outlet 31 from hitting the shape-changing member 51 . Desirably, member 57 is included.

The windbreak member 57 is attached so as to cover, for example, the portion other than the lower surface of the shape-changing member 51 (that is, the surface facing the private room 91). It is desirable that the windbreak member 57 have heat insulation. The windbreak member 57 is arranged without being in contact with the shape-changing member 51 so as not to hinder the shape change of the shape-changing member 51 .

In this manner, the first opening degree adjusting mechanism 41 includes the windbreak member 57, so that the amount of air blown from the first outlet 31 can be adjusted with high accuracy. Note that the windbreak member 57 may simply be implemented by a wind direction plate that guides the direction of the wind from the first outlet 31 to the opposite side of the shape-changing member 51 .

(Concerning the configuration example of the second opening adjustment mechanism)
A configuration example of the second opening adjustment mechanism 44 will be described with reference to FIGS. 7 to 9. FIG. The configuration of the second opening adjustment mechanism 44 is basically the same as the configuration of the first opening adjustment mechanisms 41 to 43 described above. The second opening degree adjusting mechanism 44 includes a shape changing member 51A instead of the shape changing member 51 in the first opening degree adjusting mechanisms 41-43. Therefore, the position changing member 52 in the second opening adjustment mechanism 44 is engaged with or connected to the shape changing member 51A, and its position is changed according to the shape change of the shape changing member 51A.

The shape-changing member 51</b>A changes its shape according to the temperature of the air in the corridor 94 . The shape-changing member 51A is made of the same material (shape memory alloy) as the shape-changing member 51, but has a different reaction temperature zone than the shape-changing member 51. As shown in FIG. In other words, the shape-changing member 51 at the first outlets 31 to 33 and the shape-changing member 51A at the second outlet 34 have different temperature zones in which the shape changes.

The shape-changing member 51A in the second degree-of-opening adjustment mechanism 44 starts to react at a temperature lower than the temperature (predetermined temperature) at which the shape-changing member 51 in the first degree-of-opening adjustment mechanisms 41 to 43 starts to react. The predetermined temperature at which the shape-changing member 51A begins to react is 24° C., for example.

7 and 8 schematically show the opening degree of the second outlet 34 when the shape-changing member 51A is in the initial state. FIG. 9 schematically shows the opening degree of the second outlet 34 when the shape-changing member 51A is in the reaction state.

When the shape-changing member 51A is in the initial state, the openings 34a to 34c of the second outlet 34 are completely closed by the opening/closing member 54. As shown in FIG. That is, in the initial state, the second outlet 34 is fully closed.

In summer, when the room temperature of the corridor 94 reaches 24° C. or higher, the shape-changing member 51A begins to expand. As the shape-changing member 51A extends, the advancing/retreating member 53 is pushed and retreats. When the advancing/retreating member 53 retreats, the opening/closing member 54 moves in a direction to widen the opening degree of the second outlet 34 . FIG. 9 shows the position of the opening/closing member 54 when the second outlet 34 is in the half-open state. The opening/closing member 54 in the second opening adjustment mechanism 44 has a fully closed position (the positions shown in FIGS. 7 and 8) in which the second outlet 34 is fully closed, and a fully open state in which the second outlet 34 is opened. fully open position.

In this embodiment, the second opening adjustment mechanism 44 is configured such that the second outlet 34 is fully opened when the room temperature in the corridor 94 is, for example, 30° C. or higher. Thus, the temperature (minimum temperature) at which the second outlet 34 is fully opened may be the same as the temperature (minimum temperature) at which the first outlets 31 to 33 are fully opened.

As shown in FIG. 10, the second opening adjustment mechanism 44 also has a windbreak for preventing the temperature-adjusted air blown from the second outlet 34 from hitting the shape-changing member 51A. A member is preferably provided. As a result, the amount of air blown from the second outlet 34 can be adjusted with high accuracy.

As described above, the minimum state of the degree of opening of the first outlets 31-33 adjusted by the first degree-of-opening adjustment mechanisms 41-43 is an open state between fully closed and fully open (for example, a half-open state). On the other hand, the minimum state of the degree of opening of the second outlet 34 adjusted by the second degree-of-opening adjustment mechanism 44 is the fully closed state. Also, the second outlet 34 starts to open when the room temperature in the corridor 94 reaches 24° C. or higher. Therefore, according to the present embodiment, the corridor 94 can be air-conditioned only in summer. This will be specifically described below.

(Regarding air conditioning in summer)
Air conditioning of the private rooms 91 to 93 and the corridor 94 when the air conditioner 2 operates in the cooling operation mode in summer will be described.

When the room temperature of the private rooms 91 to 93 is less than 26° C., such as when the temperature is relatively low even in summer, the first outlets 31 to 33 of the private rooms 91 to 93 are half-opened. When the room temperature of the private rooms 91 to 93 reaches 26° C. or higher during a time zone that is susceptible to solar radiation, such as midsummer daytime, the opening degrees of the first air outlets 31 to 33 are adjusted by the opening degree adjusting mechanisms 41 to 43. adjusted to be larger. Therefore, even if the resident does not operate the remote control 11 or the like, it is possible to adjust the air volume of cool air according to the room temperature.

The second outlet 34 of the corridor 94 is fully closed when the room temperature is less than 24°C. The second outlet 34 is opened. Therefore, the cooling of the corridor 94 can be started even if the resident does not operate the remote control 11 or the like.

In addition, similarly to the first outlets 31 to 33, when the room temperature in the corridor 94 is 24° C. or higher, the second opening adjustment mechanism 44 adjusts the opening of the second outlet 34 according to the room temperature. is adjusted. Therefore, even if the resident does not operate the remote controller 11 or the like, it is possible to adjust the air volume of cool air according to the room temperature even in the corridor 94 .

FIG. 11 is a graph showing the cooling effect of the second floor hallway 94 when the air conditioning system 1 is applied. The solid line in FIG. 11 shows the room temperature change in one day in high summer when the present air conditioning system 1 is applied, and the dashed dotted line in FIG. room temperature change.

As shown in FIGS. 13 and 14, in the known air-conditioning system 101, the second-floor corridor 94 is not provided with an air outlet, so the room temperature is always about 30° C. or higher. On the other hand, in the present air conditioning system 1, the second air outlet 34 is provided in the second floor corridor 94, and the degree of opening thereof is automatically adjusted. Therefore, according to the air conditioning system 1 , the room temperature in the evening can be lowered by about 2.7° C. (ΔT) compared to the known air conditioning system 101 . Therefore, according to the air conditioning system 1, it is possible to effectively alleviate the heat in the second floor hallway 94 when returning home.

In addition, although the room temperature varies depending on the orientation and outer skin area of the private rooms 91 to 93, or the position of the windows provided in the private rooms 91 to 93, in the present embodiment, according to the room temperature of each of the private rooms 91 to 93, the second The opening degrees of the one outlets 31 to 33 are individually adjusted within a range from half-open to full-open. Therefore, variations in room temperature among the private rooms 91 to 93 can be suppressed.

(About air conditioning in winter)
Air conditioning of the private rooms 91 to 93 and the corridor 94 when the air conditioner 2 operates in the heating operation mode in winter will be described.

The room temperature in winter is about 10° C. or lower when the room is not heated, and is about 23° C. or lower even when the room is heated. Therefore, the shape-changing members 51 provided at the first outlets 31-33 of the private rooms 91-93 and the shape-changing member 51A provided at the second outlet 34 of the corridor 94 are both in the initial state. . That is, the first outlets 31 to 33 of the private rooms 91 to 93 are half-opened, and the second outlet 34 of the corridor 94 is fully closed.

Therefore, in winter, warm air is not supplied to the corridor 94, but only to the private rooms 91-93. The temperature of the second floor corridor 94 in winter is relatively higher than the entrance and corridor of the first floor, and the temperature environment is not so bad. Therefore, the heating load can be reduced by not air-conditioning the second-floor corridor 94 in winter.

FIG. 12 is a graph comparing the heating load when the second air outlet 34 with automatic opening adjustment is installed in the second-floor hallway 94 and the heating load when a commercially available air outlet is installed. Since the outlet of the commercially available product is always open, the heating load is larger than that of the air conditioning system 1 of the present invention. This simulation result shows that the air conditioning system 1 can reduce the heating load by about 7% compared to the case where a commercially available outlet is installed.

As described above, according to the air conditioning system 1, the second floor corridor 94 is air-conditioned in summer, so the temperature environment of the second floor corridor 94 in summer can be improved. In addition, since the second-floor corridor 94 is not air-conditioned in winter, the air-conditioning load can be reduced throughout the year.

In addition, since the opening degree adjusting mechanisms 41 to 43 are provided in the private rooms 91 to 93, respectively, the opening degrees of the outlets 31 to 33 are individually adjusted. Thereby, temperature unevenness among the private rooms 91 to 93 can be reduced. Therefore, according to the air conditioning system 1, the temperature environment of the private rooms 91 to 93 can be efficiently improved without the need for the resident to manually adjust the air volume balance. As a result, the resident can spend comfortably in the second floor portion 90 of the house including the private rooms 91-93 and the corridor 94. FIG.

In addition, since the air conditioning system 1 does not require a damper as disclosed in Patent Document 2, it is possible to reduce power consumption with a simple configuration. Also, since no damper is required, the initial cost and running cost can be reduced. Furthermore, maintenance and replacement of dampers and the like can be eliminated.

In this embodiment, the opening degree of the outlet increases as the shape-changing members 51 and 51A expand, but conversely, the opening degree of the outlet increases as the shape-changing members 51 and 51A contract. The opening adjustment mechanism may be configured as follows.

(Modification)
In the present embodiment, an example in which a plurality of living rooms (private rooms 91 to 93) and one non-living room (corridor 94) are targeted for air conditioning has been described. There may be two or more non-living rooms to be air-conditioned.

In addition, in the present embodiment, the first outlet that is always open is provided in the living room, and the second outlet that can be fully closed is provided in the non-living room, but this is not a limitation. For example, both the first outlet and the second outlet may be provided in different non-residential rooms. In this case, a first air outlet that is always open is provided in non-occupied rooms such as washrooms that are frequently used (long stays), and a first outlet that can be fully closed is provided in passage rooms such as corridors that are used infrequently. Two outlets may be provided.

Moreover, in the present embodiment, the adjustment range of the opening degree of the first outlet and the adjustment range of the opening degree of the second outlet are set to be different, but this is not restrictive. For example, the opening degree adjustment mechanism provided for the first outlet and the opening degree adjustment mechanism provided for the second outlet are such that when the first outlet is fully open, the second outlet is fully closed. state, and when the first outlet is in the fully closed state, the second outlet may be in the fully open state.

Specifically, a first air outlet and a second air outlet are provided in the entrance (non-living room) on the first floor and the corridor (non-living room) on the second floor, respectively, and these air outlets are used in summer and winter. Mouth opening may be adjusted in the opposite direction. As a result, the second-floor corridor can be air-conditioned only in summer, and the first-floor entrance can be air-conditioned only in winter. Therefore, it is possible to efficiently air-condition the entrance on the first floor and the corridor on the second floor.

Further, in the present embodiment, both the first outlet and the second outlet are provided with the opening adjustment mechanism, but only one of them is provided with the opening adjustment mechanism. good too.

Further, although the shape-changing members 51 and 51A are described as being shape memory alloys, they are not limited to this as long as they are members whose shape changes according to temperature when the temperature reaches a predetermined temperature or higher. For example, the shape-changing member may be a bimetal or a piezoelectric element.

In addition, in the present embodiment, the air conditioning system 1 is applied to a residence, but as long as it is a building that includes a plurality of indoor spaces, it can be applied to buildings other than residences (office buildings, nursing homes, hotels, etc.). can also For example, if the building to which the air conditioning system 1 is applied is an office building, the living room provided with the first outlet can be the office, and the non-residential room provided with the second outlet can be the corridor.
