Summary of the Invention

Problems to be Solved by the Invention

[0004] When using a common space as an air-conditioned room and using a general-purpose air conditioner, a decrease in effective area and an increase in cost are suppressed as compared with the case of installing a dedicated air conditioner in a dedicated air-conditioned room. However, when using a general-purpose air conditioner, it is difficult to supply downwardly inclined blown air to each living room. Further, when using a common space as an air-conditioned room, the temperature difference between the common space and each living room becomes large, and the comfort level decreases.

[0005] The present disclosure has been made in view of such circumstances, and an object thereof is to provide a technique for suppressing a decrease in air conditioning efficiency even when an air conditioner is installed in a common space.

Means for Solving the Problems

[0006] To solve the above problems, an air conditioning system according to an aspect of the present disclosure includes an air conditioner installed on an indoor wall, which sucks indoor air from an air conditioning intake port and blows out conditioned air from an air conditioning outlet, and an adapter that communicates the air conditioning outlet with a ceiling opening provided in the indoor ceiling to suppress leakage of the conditioned air into the room. The adapter includes a leakage prevention bottom surface that curves downward from the air conditioning outlet and extends upward through the front of the air conditioner toward the ceiling.

[0007] Another aspect of the present disclosure is an adapter. This adapter communicates the air conditioning outlet of an air conditioner installed on an indoor wall, which sucks the indoor air from the air conditioning intake port and blows out the conditioned air from the air conditioning outlet, with a ceiling opening provided in the indoor ceiling, and includes a leakage prevention bottom surface that curves downward from the air conditioning outlet and extends upward through the front of the air conditioner toward the ceiling.

[0008] In addition, any combination of the above components, and those obtained by converting the expressions of the present disclosure among a method, an apparatus, a system, a recording medium, a computer program, etc. are also effective as aspects of the present disclosure.

Advantages of the Invention

[0009] According to the present disclosure, even when an air conditioner is installed indoors, a decrease in the efficiency of air conditioning can be suppressed.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Before specifically describing the embodiments of the present disclosure, an overview of the embodiments will be described. This embodiment relates to an air conditioning system that performs whole-house air conditioning in a house having a common space and a plurality of living rooms. In order to suppress a decrease in effective area and an increase in cost, the air conditioning system does not use a dedicated air conditioning room and a dedicated air conditioner. Therefore, the air conditioning system installs a general-purpose air conditioner in a common space such as a corridor and uses the common space as an air conditioning room. In addition, a transport fan is installed in the ceiling opening of the common space, and the transport fan transports the air in the common space to each living room via a duct. In such a situation, as described above, it is difficult to supply the obliquely downward blown air to each living room, and the comfort level decreases due to an increase in the temperature difference between the common space and each living room. To improve these problems, the air conditioning system attaches an adapter to the air conditioner that at least covers the lower side and the front side of the air conditioner and guides the air blown downward from the air conditioner to the ceiling opening.

[0012] The embodiments described below all show preferred specific examples of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement positions and connection forms of the components, as well as the steps (processes) and the order of the steps shown in the following embodiments are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the most general concept of the present disclosure are described as arbitrary components. Also, in each figure, the same reference numerals are assigned to substantially the same configurations, and duplicate descriptions are omitted or simplified.

[0013] Hereinafter, the embodiments will be described in the order of (1) overall configuration, (2) the adapter and its peripheral configuration, and (3) air volume control. (1) Overall configuration FIG. 1 is a top view showing the configuration of a house 500 in which an air conditioning system 1000 is installed, and FIG. 2 is a cross-sectional view showing the configuration of the house 500 in which the air conditioning system 1000 is installed. The house 500 may be a dwelling unit in an apartment building or the like, or a detached house. The house 500 includes a first bedroom 10a to a fourth bedroom 10d, and a common space 14, which are collectively referred to as a living room 10. The living room 10 constitutes a living space where people stay inside for a long time. The common space 14 is a space where people stay inside for a shorter time compared to living spaces such as passages like corridors and entrances, and storage spaces like closets, and is adjacent to the living room 10. Also, the common space 14 and the living room 10 communicate with each other in a ventilable manner, and air circulates from each living room 10 to the common space 14.

[0014] The air conditioning system 1000 includes an outdoor air inlet 100, an outdoor air intake duct 102, a heat exchange ventilation fan 104, an exhaust duct 106, an exhaust port 108, a heat exchange duct 110, a heat exchange outlet 112, a conveying fan 120, a conveying duct 130, a branch chamber 140, first to seventh branch conveying ducts 142a to 142g collectively referred to as the branch conveying duct 142, first to seventh outlets 144a to 144g collectively referred to as the outlet 144, an air conditioner 300, and an adapter 400. The outdoor air intake duct 102, the exhaust duct 106, the heat exchange duct 110, the conveying duct 130, and the branch conveying duct 142 are pipes for transporting air, that is, air ducts.

[0015] The outdoor air inlet 100 is installed on the wall surface of the house 500. The outdoor air intake duct 102 extending from the outdoor air inlet 100 toward the inside of the house 500 is connected to the heat exchange ventilation fan 104. The heat exchange ventilation fan 104 is disposed, for example, in the ceiling space 16 of the common space 14. The exhaust duct 106 is also connected to the heat exchange ventilation fan 104. The exhaust duct 106 extends toward the wall surface of the house 500 and is connected to the exhaust port 108 installed on the south wall surface. The heat exchange duct 110 is also connected to the heat exchange ventilation fan 104.

[0016] The heat exchange and ventilation fan 104 takes in outside air 200 from the outside air inlet 100 through the outside air intake duct 102. The outside air 200 sucked in from the outside air inlet 100 corresponds to the supply air. Also, the heat exchange and ventilation fan 104 takes in ventilation RA (Return Air) 202 from a ventilation opening (not shown). The ventilation RA 202 is the indoor air that has flowed in from inside the house 500, for example, from the interior including the living room 10 and the common space 14. The heat exchange and ventilation fan 104 performs heat exchange between these. As a result of the heat exchange, the heat exchange and ventilation fan 104 discharges the exhaust air 204 from the exhaust port 108 through the exhaust duct 106. Also, the heat exchange and ventilation fan 104 discharges the heat-exchanged supply air 208 (outside air 200) from the heat exchange outlet 112 via the heat exchange duct 110. The heat exchange outlet 112 is an opening provided in the ceiling of the common space 14. That is, the heat exchange and ventilation fan 104 blows out the supply air 208 (heat-exchanged supply air), which is the outside air 200 heat-exchanged with the ventilation RA 202 exhausted from the living space, from the heat exchange outlet 112 into the common space 14. If the heat exchange between the ventilation RA 202 and the outside air 200 is sufficient, it may be configured to connect the heat exchange outlet 112 to the conveyance fan 120 described later. With such a configuration, since it does not pass through the common space 14, the supply air 208 can be reliably sent to the conveyance fan 120.

[0017] The air conditioner 300 is installed on the wall (not shown) of the common space 14 instead of a dedicated air-conditioning room. An air-conditioning intake port 310 is provided at the upper end of the air conditioner 300. A heat exchanger air outlet 112 is provided vertically above the air conditioner 300, and the supply air 208 blown out from the heat exchanger air outlet 112 flows in. Further, the circulation RA206 flows into the air-conditioning intake port 310 from the common space 14 inside the house 500. The circulation RA206 corresponds to the supply air that has moved inside the house 500, similar to the ventilation RA202. The air conditioner 300 is a general-purpose air conditioner and performs air conditioning on the circulation RA206 and the supply air 208. The air conditioner 300 controls the temperature, humidity, etc. with respect to the circulation RA206 and the supply air 208 so as to reach the set temperature (hereinafter referred to as the "set temperature"). An air-conditioning outlet 320 is provided at the lower end of the air conditioner 300, and the air conditioner 300 blows out the air-conditioned air (air-conditioned air 210) from the air-conditioning outlet 320. That is, the air conditioner 300 sucks in the air from the common space 14 through the air-conditioning intake port 310 and blows out the air-conditioned air 210 from the air-conditioning outlet 320.

[0018] A ceiling opening 122 is provided in the ceiling of the common space 14. The conveying fan 120 installed in the ceiling space 16 sucks in the air-conditioned air 210 and the circulation RA206 (hereinafter, these may also be referred to as the "air-conditioned air 210") from the ceiling opening 122. The conveying fan 120 is connected to the branch chamber 140 via the conveying duct 130 and conveys the air-conditioned air 210 to the branch chamber 140.

[0019] The branch chamber 140 is installed in the ceiling space 16, connected to the conveying fan 120, and also connected to the first branch conveying duct 142a to the seventh branch conveying duct 142g. The first branch conveying duct 142a is connected to the first air outlet 144a installed in the first living room 10a, and the second branch conveying duct 142b is connected to the second air outlet 144b installed in the second living room 10b. The third branch conveying duct 142c is connected to the third air outlet 144c installed in the third living room 10c, and the fourth branch conveying duct 142d is connected to the fourth air outlet 144d installed in the fourth living room 10d. The fifth branch conveying duct 142e is connected to the fifth air outlet 144e installed in the first living room 10a, and the sixth branch conveying duct 142f is connected to the sixth air outlet 144f installed in the second living room 10b. The seventh branch conveying duct 142g is connected to the seventh air outlet 144g installed in the fourth living room 10d.

[0020] The conveying fan 120 conveys the air-conditioned air 210 from the first living room 10a to the fourth living room 10d via the conveying duct 130, the branch chamber 140, the first branch conveying duct 142a to the seventh branch conveying duct 142g, and the first air outlet 144a to the seventh air outlet 144g. Each air outlet 144 is installed on the side wall surface or the ceiling surface of each living room 10, and discharges the air-conditioned air 210 sent from the conveying fan 120 into each living room 10. Since each living room 10 is connected to the common space 14, the air-conditioned air 210 blown out from the air outlet 144 also circulates in the common space 14. A part of the circulating air flows into the air conditioner 300 as the circulating RA206. Also, the circulating RA206 may flow into the conveying fan 120 from the ceiling opening 122. Furthermore, another part of the circulating air is taken in by the heat exchange type ventilation fan 104 as the ventilation RA202.

[0021] When the conditioned air 210 blown out from the air-conditioning outlet 320 of the air conditioner 300 diffuses into the common space 14, the amount of the conditioned air 210 sucked into the conveying fan 120 through the ceiling opening 122 decreases. As a result, the amount of the conditioned air 210 supplied to each living room 10 also decreases, so the efficiency of air conditioning decreases. In order to suppress the decrease in the efficiency of air conditioning, in this embodiment, as shown in FIG. 2, an adapter 400 is installed in the common space 14. The adapter 400 communicates the air-conditioning outlet 320 and the ceiling opening 122, and suppresses the leakage of the conditioned air 202 into the common space 14. When the leakage of the conditioned air 202 into the common space 14 is suppressed, the decrease in the amount of the conditioned air 210 sucked into the conveying fan 120 through the heat exchange outlet 112 is also suppressed. (2) Adapter and its surrounding configuration FIG. 3 shows the configurations of the air conditioner 300 and the adapter 400. Also, FIG. 9 shows the positional relationship among the air conditioner 300, the adapter 400, and the ceiling opening 122 in a side view, and FIG. 10 shows the positional relationship between the air conditioner 300 and the heat exchange duct 110 in a side view. As described above, the air conditioner 300 is installed on the wall of the common space 14. An air-conditioning suction port 310 is arranged at the upper end of the air conditioner 300, and an air-conditioning outlet 320 is arranged at the lower end of the air conditioner 300. Also, a heat exchange outlet 112 and a ceiling opening 122 are provided in the ceiling of the common space 14. For example, the heat exchange outlet 112 and the air-conditioning suction port 310 face each other. As shown in FIG. 10, the heat exchange duct 110 may be drawn out from the ceiling so that the heat exchange outlet 112 and the air-conditioning suction port 310 are located on substantially the same plane. In other words, the tip of the heat exchange duct 110 and the upper end of the air conditioner 300 may be brought into contact with each other. With such a configuration, the supply air 208 (heat exchange supply air) can be prevented from diffusing into the common space 14, and the entire amount of the supply air 208 can be air-conditioned by the air conditioner 300 and then supplied to each room.

[0022] The adapter 400 includes a leakage prevention bottom surface 402, a leakage prevention top surface 404, and a first leakage prevention side surface 406a and a second leakage prevention side surface 406b collectively referred to as a leakage prevention side surface 406. Leakage prevention The bottom surface 402 is arranged to cover at least partially the air-conditioning outlet 320 vertically below the air conditioner 300 and extends upward while curving toward the ceiling. Thus, the leakage-preventing bottom surface 402 includes not only a flat surface but also a curved surface. The leakage-preventing top surface 404 is arranged between the ceiling of the common space 14 and the air conditioner 300, facing the leakage-preventing bottom surface 402.

[0023] The first leakage-preventing side surface 406a and the second leakage-preventing side surface 406b are connected to the leakage-preventing bottom surface 402 and the leakage-preventing top surface 404 and are arranged facing each other. Further, the first leakage-preventing side surface 406a has a first notch portion 407a with an upper portion on the air conditioner 300 side missing, and the second leakage-preventing side surface 406b has a second notch portion 407b with an upper portion on the air conditioner 300 side missing. The first notch portion 407a and the second notch portion 407b are collectively referred to as the notch portion 407. Due to the notch portion 407, the adapter 400 is fixed with the air-conditioning suction port 310 exposed to the common space 14.

[0024] As shown in FIGS. 3 and 9, the space surrounded by the leakage-preventing bottom surface 402, the leakage-preventing top surface 404, the first leakage-preventing side surface 406a, and the second leakage-preventing side surface 406b is the air supply space 408, and the air supply space 408 is spatially independent from the common space 14. The downstream end portions of the leakage-preventing bottom surface 402, the leakage-preventing top surface 404, the first leakage-preventing side surface 406a, and the second leakage-preventing side surface 406b are connected to the ceiling of the common space 14 while surrounding the ceiling opening 122.

[0025] Further, the upstream ends of the leak prevention bottom surface 402, the leak prevention top surface 404, the first leak prevention side surface 406a, and the second leak prevention side surface 406b surround and cover the air conditioning outlet 320. In other words, the upstream end of the leak prevention bottom surface 402 is located below the air conditioning outlet 320, and the upstream end of the leak prevention top surface 404 is located above the air conditioning outlet 320. Also, when viewing the air conditioner 300 from the front, the upstream end of the first leak prevention side surface 406a is located to the left of the air conditioning outlet 320, and the upstream end of the second leak prevention side surface 406b is located to the right of the air conditioning outlet 320. With such a configuration, the conditioned air 210 blown out from the air conditioning outlet 320 is guided to the ceiling opening 122 through the air supply space 408. In other words, it is possible to suppress the diffusion of the conditioned air 210 into the common space 14. Note that the upstream end of the leak prevention top surface 404 may be configured to abut against the air conditioner 300 above the air conditioning outlet 320. With such a configuration, it is possible to further suppress the leakage of the conditioned air 210 guided to the ceiling opening 122 from the air supply space 408 into the common space 14. Also, the upstream ends of the leak prevention bottom surface 402, the first leak prevention side surface 406a, and the second leak prevention side surface 406b may also abut against the air conditioner 300.

[0026] The supply air 208 blown out from the heat exchange outlet 112 is sucked into the air conditioning suction port 310 of the air conditioner 300. Also, the circulation RA206 in the common space 14 passes through the first notch 407a of the first leak prevention side surface 406a or the second notch 407b of the second leak prevention side surface 406b and is sucked into the air conditioning suction port 310 of the air conditioner 300. Further, the conditioned air 210 blown out from the air conditioning outlet 320 of the air conditioner 300 is mainly guided to the ceiling opening 122 by passing through the air supply space 408.

[0027] The leakage prevention bottom surface 402 is designed with a streamline shape from the air-conditioning outlet 320 towards the ceiling opening 122 in order to quickly suck the air-conditioning air 210 blown out from the air-conditioning outlet 320 into the ceiling opening 122. Note that if it is possible to guide the air-conditioning air 210 to the ceiling opening 122, a shape other than the streamline design may be used. For example, the leakage prevention bottom surface 402 may be formed into a shape that is bent rather than curved. The leakage prevention top surface 404 can also be said to be an air duct separation plate for preventing the air-conditioning air 210 blown out from the air-conditioning outlet 320 from going to the air-conditioning suction port 310.

[0028] Figures 4(a)-(d) show the configurations of the air conditioner 300, the conveying fan 120, and the branch chamber 140. Figure 4(a) shows the configuration when the air conditioner 300, the conveying fan 120, and the branch chamber 140 are viewed obliquely from above. Figure 4(b) shows the sectional configuration when the air conditioner 300, the conveying fan 120, and the branch chamber 140 are viewed obliquely from above. Figure 4(c) shows the configuration when the air conditioner 300, the conveying fan 120, and the branch chamber 140 are viewed from the side. Figure 4(d) shows the sectional configuration when the air conditioner 300, the conveying fan 120, and the branch chamber 140 are viewed from above. The conveying duct 130, which has been omitted until now, is connected to the conveying fan 120 and the branch chamber 140, and guides the air-conditioning air 210 from the conveying fan 120 to the branch chamber 140.

[0029] The downstream end of the adapter 400 is fixed to the ceiling by the downstream end fixing portion 410. The downstream end fixing portion 410 is, for example, an L-shaped metal fitting and is fixed to the downstream end of the adapter 400 and the ceiling using screws or the like. Regarding the downstream end fixing portion 410, fixing to the ceiling is prioritized in order to prevent air from directly entering the ceiling opening 122 from the common space 14, but it may also be detachable.

[0030] The upstream end of the adapter 400 is fixed to at least one of the wall or the air conditioner 300 by the upstream end fixing portion 412. The upstream end fixing portion 412 is also, for example, an L-shaped metal fitting, and is fixed to at least one of the wall or the air conditioner 300 and the upstream end of the adapter 400 using screws or the like. The upstream end fixing portion 412 may also be detachable.

[0031] The upstream side of the leak prevention top surface 404, that is, the end on the air conditioner 300 side, is called the top surface upstream side end 416, and an inflow opening 414 is formed between the top surface upstream side end 416 and the air conditioner 300. The inflow opening 414 is an opening for allowing the circulation RA206 of the common space 14 to flow into the blowing space 408. When the air volume of the conveying fan 120 is larger than the air volume of the air conditioner 300, the load on the air conditioner 300 increases. The inflow opening 414 is provided to reduce the load on the air conditioner 300. Also, the inflow opening 414 is located below the top surface upstream side end 416 and the air conditioner suction port 310 in order to avoid the occurrence of a short circuit. Further, the leak prevention top surface 404 may be provided with an inflow opening adjustment portion for adjusting the size of the inflow opening 414. The inflow opening adjustment portion is, for example, a shutter that slides along the leak prevention top surface 404. In addition, when the load on the air conditioner 300 is small, the inflow opening 414 may be fully closed by the inflow opening adjustment portion, and the top surface upstream side end 416 may be brought into contact with the air conditioner 300.

[0032] The leak prevention bottom surface 402 is provided with an openable and closable opening and closing panel portion 420. By opening the opening and closing panel portion 420, the maintenance opening 418 in the leak prevention bottom surface 402 is exposed. The maintenance opening 418 is an opening for performing maintenance on the air conditioner 300 with the adapter 400 communicating with the air conditioner 300. For example, it is possible to clean the air conditioner 300 with a vacuum cleaner through the maintenance opening 418.

[0033] A first filter 422a is attached to the first notch portion 407a, and a second filter 422b is attached to the second notch portion 407b. Therefore, the first filter 422a is provided on substantially the same plane as the first leakage prevention side surface 406a, and the second filter 422b is provided on substantially the same plane as the second leakage prevention side surface 406b. The first filter 422a and the second filter 422b are collectively referred to as the filter 422. The filter 422 purifies the circulation RA206 sucked from the common space 14 to the air conditioning suction port 310 on the upstream side of the air conditioning suction port 310. With such a configuration, the inside of the air conditioner 300 can be kept clean, and the frequency of maintenance of the air conditioner 300 performed through the maintenance opening 418 can be reduced.

[0034] A first ventilation gap 424a is arranged between the first filter 422a and the side surface of the air conditioner 300, and a second ventilation gap 424b is arranged between the second filter 422b and the side surface of the air conditioner 300. The first ventilation gap 424a and the second ventilation gap 424b are collectively referred to as the ventilation gap 424. The ventilation gap 424 is a gap for ventilating the circulation RA206 of the common space 14 that has passed through the filter 422 to the air conditioning suction port 310. Such a ventilation gap 424 ensures the effective area of the filter 422. The effective area is ensured. (3) Air volume control Hereinafter, the control of the air volume of the air conditioner 300 (hereinafter referred to as the "air conditioner air volume") and the air volume of the conveying fan 120 (hereinafter referred to as the "fan air volume") will be described in the order of (3-1) the first configuration, (3-2) the second configuration, and (3-3) the third configuration. Also, the control of the air volume of the conveying fan 120 and the air volume of the heat exchange ventilation fan 104 (hereinafter referred to as the "heat exchange air volume") will be described in (3-4) the fourth configuration. Hereinafter, as an example, one controller for controlling the air conditioner 300 and the conveying fan 120 is illustrated. If each air volume can be controlled, a configuration may be adopted in which a controller for controlling the air conditioner 300 and a controller for controlling the conveying fan 120 are provided separately. (3-1) The first configuration In the first configuration, the air conditioning air volume of the air conditioner 300 is adjusted according to the fan air volume of the transport fan 120. FIGS. 5(a)-(b) show the first configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 5(a), the air conditioning system 1000 includes a transport fan 120, an air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 further includes a room temperature acquisition unit 462, a fan air volume control unit 466, a fan air volume acquisition unit 468, and an air conditioning air volume control unit 472.

[0035] The temperature sensor 450 is installed in the living room 10 and detects the temperature of the living room 10 (hereinafter referred to as "room temperature"). The temperature sensor 450 has a communication function such as wireless communication and transmits the detected room temperature to the controller 460. The transport fan 120 transmits the set fan air volume of the transport fan 120 to the controller 460.

[0036] The controller 460 is installed in the house 500 shown in FIGS. 1 and 2. The controller 460 controls the entire air conditioning system 1000. The controller 460 is communicably connected to the transport fan 120, the air conditioner 300, and the temperature sensor 450 via wireless communication. At least a part of these may be communicably connected by wired communication. The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The fan air volume acquisition unit 468 acquires the fan air volume by receiving the fan air volume setting from the transport fan 120. Note that the fan air volume may be acquired from the transport fan 120 or from the fan air volume control unit 466.

[0037] The fan air volume control unit 466 receives the room temperature from the room temperature acquisition unit 462. FIG. 5(b) is an example of a table held in the fan air volume control unit 466. As shown in the figure, the room temperature and the fan air volume are associated with each other. The fan air volume control unit 466 determines the fan air volume by referring to the table based on the acquired room temperature. Returning to FIG. 5(a), at this time, when the determined fan air volume is smaller than the air conditioning air volume, the air conditioning air volume control unit 472 sets the air conditioning air volume to be equal to or less than the fan air volume. The air conditioning air volume control unit 472 adjusts the air conditioning air volume of the air conditioner 300 by transmitting the determined air conditioning air volume to the air conditioner 300. Here, "setting the air conditioning air volume to be equal to or less than the fan air volume" also includes making the air conditioning air volume equal to the fan air volume. By making the fan air volume acquired by the fan air volume acquisition unit 468 equal to the air conditioning air volume, the load on the air conditioner 300 can be suppressed while the conditioned air 210 can be conveyed to each room. (3-2) Second configuration In the second configuration, the fan air volume of the transport fan 120 is adjusted according to the air conditioning air volume of the air conditioner 300. FIGS. 6(a)-(b) show the second configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 6(a), the air conditioning system 1000 includes a transport fan 120, an air conditioner 300, a temperature sensor 450, and a controller 460. The controller 460 also includes a room temperature acquisition unit 462, an air conditioning temperature control unit 470, an air conditioning air volume control unit 472, an air conditioning air volume acquisition unit 464, and a fan air volume control unit 466. The temperature sensor 450 detects the room temperature of the room 10 and transmits the detected room temperature to the controller 460. The air conditioner 30 0 transmits the set air conditioning air volume of the air conditioner 300 to the controller 460.

[0038] The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The air volume acquisition unit 464 of the air conditioner acquires the air volume of the air conditioner by receiving the setting of the air volume of the air conditioner from the air conditioner 300. Note that the air volume of the air conditioner may be acquired from the air conditioner 300 or from the air volume control unit 472 of the air conditioner. The air temperature control unit 470 receives the room temperature from the room temperature acquisition unit 462. Further, the air temperature control unit 470 receives the set temperature of the air conditioner 300 from an operation unit (not shown). The air temperature control unit 470 determines the temperature of the air conditioner 300 (hereinafter referred to as the "air temperature") based on the room temperature and the set temperature. Any known technique may be used to determine the air temperature. For example, the air temperature is determined such that the room temperature approaches the set temperature. The air temperature control unit 470 adjusts the air temperature of the air conditioner 300 by transmitting the determined air temperature to the air conditioner 300.

[0039] The air volume control unit 472 of the air conditioner receives the room temperature from the room temperature acquisition unit 462. FIG. 6(b) is an example of a table held by the air volume control unit 472 of the air conditioner. As shown in the figure, the room temperature and the air volume of the air conditioner are associated with each other. The air volume control unit 472 of the air conditioner determines the air volume of the air conditioner by referring to the table based on the acquired room temperature. Returning to FIG. 6(a). At this time, when the determined air volume of the air conditioner is larger than the fan air volume, the fan air volume control unit 466 sets the fan air volume to be equal to or greater than the air volume of the air conditioner. The fan air volume control unit 466 adjusts the fan air volume of the transport fan 120 by transmitting the determined fan air volume to the transport fan 120. Here, "setting the fan air volume to be equal to or greater than the air volume of the air conditioner" also includes making the fan air volume equal to the air volume of the air conditioner. By making the air volume of the air conditioner acquired by the air volume acquisition unit 464 equal to the fan air volume, the air-conditioning air 210 can be transported to each room while suppressing the load on the air conditioner 300. (3-3) Third configuration In the third configuration, the fan air volume of the transport fan 120 and the air conditioning air volume of the air conditioner 300 are adjusted together. FIGS. 7(a)-(b) show the third configuration of the controller 460 in the air conditioning system 1000. As shown in FIG. 7(a), the air conditioning system 1000 includes a transport fan 120, an air conditioner 300, a temperature sensor 450, and a controller 460. Further, the controller 460 includes a room temperature acquisition unit 462 and an air volume control unit 474. The temperature sensor 450 detects the room temperature of the room 10 and transmits the detected room temperature to the controller 460.

[0040] The room temperature acquisition unit 462 of the controller 460 acquires the room temperature by receiving the room temperature from the temperature sensor 450. The air volume control unit 474 receives the room temperature from the room temperature acquisition unit 462. FIG. 7(b) is an example of a table held in the air volume control unit 474. As shown in the figure, the air conditioning air volume and the fan air volume are associated with the room temperature. Here, the fan air volume is set to be equal to or greater than the air conditioning air volume for the same room temperature. The air volume control unit 474 determines the air conditioning air volume and the fan air volume by referring to the table based on the acquired room temperature. The air volume control unit 474 adjusts the air conditioning air volume of the air conditioner 300 and the fan air volume of the transport fan 120 by transmitting the determined air conditioning air volume to the air conditioner 300 and the determined fan air volume to the transport fan 120. (3-4) Fourth configuration In the fourth configuration, the fan air volume of the transport fan 120 is adjusted according to the heat exchange air volume of the heat exchange ventilation fan 104. FIGS. 8(a)-(b) show the fourth configuration of the controller 460 in the air conditioning system 1000. As shown in FIGS. 8(a) and 8(b), the air conditioning system 1000 includes a heat exchange ventilation fan 104, a transport fan 120, and a controller 460. Further, the controller 460 includes a heat exchange air volume storage unit 478, a heat exchange air volume acquisition unit 476, and a fan air volume control unit 466a.

[0041] The heat exchange air volume storage unit 478 stores the setting of the heat exchange air volume generated by the heat exchange ventilation fan 104. The heat exchange air volume storage unit 478 is set, for example, according to the size of the house 500 during construction. Stores the settings of the defined heat exchange ventilation fan 104.

[0042] The heat exchange supply air volume acquisition unit 476 acquires the heat exchange supply air volume by receiving the setting of the heat exchange supply air volume from the heat exchange ventilation fan 104. Note that the setting of the heat exchange supply air volume stored in the heat exchange supply air volume storage unit 478 may be received as shown in FIG. 8(b).

[0043] The fan air volume control unit 466a controls the transport fan 120 based on the heat exchange supply air volume received from the heat exchange supply air volume acquisition unit 476. When the heat exchange supply air volume is greater than the fan air volume, the fan air volume control unit 466a makes the fan air volume equal to or greater than the heat exchange supply air volume. The fan air volume control unit 466a adjusts the fan air volume of the transport fan 120 by transmitting the determined fan air volume to the transport fan 120.

[0044] Note that the fourth configuration is mainly a method for controlling the lower limit value of the fan air volume, and is effective as a means for ensuring the fan air volume necessary to supply all the supply air 208 to each room even when the air conditioner 300 is stopped and the air conditioning air volume becomes zero during the intermediate periods of spring and autumn. Therefore, by combining it with each of the (3-1) first configuration, (3-2) second configuration, and (3-3) third configuration, it becomes possible to control the air volume of each device for performing necessary and sufficient air conditioning and ventilation throughout the year.

[0045] The subject of the device, system, or method in the present disclosure includes a computer. By executing a program on this computer, the functions of the subject of the device, system, or method in the present disclosure are realized. The computer mainly includes a processor that operates according to the program as a hardware configuration. The type of the processor is not limited as long as it can realize functions by executing the program. The processor is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or LSI (Large Scale Integration). The plurality of electronic circuits may be integrated on one chip or provided on a plurality of chips. The plurality of chips may be integrated into one device or provided in a plurality of devices. The program is recorded on a non-transitory recording medium such as a computer-readable ROM, optical disk, or hard disk drive. The program may be pre-stored in the recording medium or supplied to the recording medium via a wide area communication network including the Internet or the like.

[0046] According to this embodiment, since the adapter 400 communicates the air conditioning outlet 320 of the air conditioner 300 with the ceiling opening 122 provided in the ceiling of the common space 14 and suppresses the leakage of the conditioned air 210 into the common space 14, even when the air conditioner 300 is installed in the common space 14, a decrease in the air conditioning efficiency can be suppressed. Further, since the adapter 400 is used, even when a general-purpose air conditioner 300 is used, the downwardly inclined blown air can be supplied to each living room 10. Further, since the adapter 400 is used, even when the common space 14 is used as an air-conditioned room, an increase in the temperature difference between the common space 14 and each living room 10 can be suppressed. Further, since an increase in the temperature difference between the common space 14 and each living room 10 is suppressed, a decrease in comfort can be suppressed.

[0047] In addition, since the conveying fan 120 communicates with the ceiling opening 122 and conveys the conditioned air 210 to the living room 10, the adapter 400 can efficiently convey the conditioned air 210 from the air conditioner 300. Further, since the adapter 400 has a blowing space 408 surrounded by a leakage prevention bottom surface 402, a leakage prevention top surface 404, and two leakage prevention side surfaces 406, leakage of the conditioned air 210 into the common space 14 can be suppressed. Also, since the downstream end fixing portion 410 fixes the downstream end of the adapter 400 to the ceiling, leakage of the conditioned air 210 into the common space 14 can be suppressed. Moreover, since the upstream end fixing portion 412 fixes the upstream end of the adapter 400 to at least one of the wall or the air conditioner 300, leakage of the conditioned air 210 into the common space 14 can be suppressed.

[0048] In addition, since the adapter 400 is fixed with the air-conditioning suction port 310 exposed to the common space 14, the circulation RA206 in the common space 14 can be sucked into the air-conditioning suction port 310. Further, since an inflow opening 414 is provided in the leakage prevention top surface 404, the circulation RA206 is made to flow into the blowing space 408, so that an increase in the load of the air conditioner 300 can be suppressed. Also, since the size of the inflow opening 414 is adjusted by the inflow opening adjustment portion, the amount of the circulation RA206 flowing into the blowing space 408 can be adjusted. Moreover, since the air-conditioning suction port 310 is provided at the upper end of the air conditioner 300 and the inflow opening 414 is located at the upstream end of the leakage prevention top surface 404 and below the air-conditioning suction port 310, the occurrence of a short circuit can be avoided.

[0049] In addition, since the leak-preventing bottom surface 402 includes the maintenance opening 418 and the opening / closing panel portion 420, maintenance of the air conditioner 300 can be performed while the adapter 400 is attached to the air conditioner 300. Also, since the filter 422 is provided, the circulating RA206 can be purified. Further, since the ventilation gap 424 is provided between the filter 422 and the air conditioner 300, the effective area of the filter 422 can be ensured. Moreover, since the heat-exchanging ventilation fan 104 blows the supply air 208 from the heat-exchanging air outlet 112 into the common space 14, the difference between the temperature of the common space 14 and the temperature of the supply air 208 can be reduced. Also, since the heat-exchanging air outlet 112 is provided vertically above the air conditioner 300, the supply air 208 can be efficiently sucked into the conditioned air 210.

[0050] In addition, since the fan air volume is adjusted based on the room temperature, a fan air volume suitable for the room temperature can be used. Also, since the fan air volume is made greater than the air-conditioning air volume, an increase in the load on the air conditioner 300 can be suppressed. Further, since the air-conditioning air volume is controlled based on the room temperature, an air-conditioning air volume suitable for the room temperature can be used. Also, since the air-conditioning air volume is made less than the fan air volume, an increase in the load on the air conditioner 300 can be suppressed. Moreover, since the fan air volume and the air-conditioning air volume are controlled such that the fan air volume becomes greater than the air-conditioning air volume, a fan air volume and an air-conditioning air volume suitable for the environment can be used while suppressing an increase in the load on the air conditioner 300.

[0051] In the embodiments of the present disclosure, as an example, the case where the air conditioner 300 is installed in the corridor which is the common space 14 as shown in FIG. 1 has been described, but the installation location of the air conditioner 300 is not limited to the corridor. It may be installed anywhere as long as it is the common space 14 adjacent to the living room 10 that constitutes the living space. For example, as shown in FIG. 11, the air conditioner 300 and the adapter 400 may be installed on the upper part of the storage space 520 adjacent to a certain living room 10e. Here, FIG. 11 is a schematic diagram showing the configuration in the case where the air conditioner 300 and the branch chamber 400 are installed in the storage space 520.

[0052] In FIG. 11, the corridor 510 is the common space 14 and is adjacent to each living room including the living room 10e in a ventilable manner. Also, the storage space 520 is the common space 14 and is adjacent to a certain living room 10e in a ventilable manner. The corridor 510 and the storage space 520 are adjacent to each other with a non-openable wall portion 534 therebetween.

[0053] A certain living room 10e and the storage space 520 are adjacent to each other with a door portion 532 therebetween. Here, the door portion 532 is openable and closes and ventilably connects the common space 14 and the living room 10.

[0054] The storage space 520 is divided into an upper part and a lower part by a storage ceiling 521 provided parallel to the floor surface. Here, the space above the storage ceiling 521 is defined as a storage ceiling pocket 522, and the space below the storage ceiling 521 is defined as a storage floor pocket 523. In FIG. 12, an air conditioner 300 and an adapter 400 are installed in the storage ceiling pocket 522 which is the upper part of the storage space 520.

[0055] In such a configuration, first, the air of each living room flows into a certain living room 10e through the corridor 510. Further, the air of each living room ventilates into the storage space 520 through a certain living room 10e and can be air-conditioned by the air conditioner 300. The conditioned air is guided to the conveying fan 120 in the ceiling space 16 through the adapter 400 and conveyed to each living room. Note that a ventilation opening 536 which is an opening for ventilably connecting the storage space 520 and the corridor 51 0 may be provided in the wall portion 534. With such a configuration, the air of each living room ventilated into the corridor 510 can be taken directly from the corridor 510 into the storage space 520 and air-conditioned.

[0056] In addition, in the embodiments of the present disclosure, as an example, the case where the conditioned air 210 is conveyed from the ceiling space 16 side to the living room 10 as shown in FIG. 2 has been described, but the present disclosure is not limited to this form. For example, as shown in FIG. 12, by installing a communication duct 135 that communicates the ceiling space 16 and the underfloor space 17, the conditioned air 210 may be configured to be conveyed from the underfloor space 17 side to the living room 10. Here, FIG. 12 is a schematic diagram showing the configuration in the case of conveying the conditioned air 210 using the underfloor space 17. In FIG. 12, the conveying fan 120 is located in the ceiling space 16, and the branch chamber 140 is located in the underfloor space 17. In FIG. 12, the communication duct 135 is further provided as an air passage of the air conditioning system 1000.

[0057] The communication duct 135 is an air passage that communicates the ceiling space 16, which is a space located above the ceiling of the common space 14, and the underfloor space 17, which is a space located below the floor surface of the common space. One end of the communication duct 135 is connected to the outlet of the conveying fan 120 installed in the ceiling space 16, and the other end is connected to the branch chamber 140 installed in the underfloor space 17. With such a configuration, the conditioned air 210 blown out from the conveying fan 120 is conveyed from the ceiling space 16 side to the underfloor space 17 side. Note that the communication duct 135 may be constructed in any manner as long as it can convey the conditioned air 210 from the ceiling space 16 side to the underfloor space 17 side. For example, as shown in FIG. 12, the communication duct 135 may be constructed to pass through the common space 14, or may be constructed to pass through the wall of the house 500 (in other words, not passing through the common space 14 and the living room 10).

[0058] In the case of such a configuration, first, the conditioned air 210 blown out from the air conditioner 300 is guided to the conveying fan 120 in the ceiling space 16 via the adapter 400. Next, the conditioned air 210 blown out from the conveying fan 120 moves from the ceiling space 16 side to the underfloor side 17 through the communication duct 135. Next, the conditioned air 210 is conveyed to each living room 10 via the branch chamber 140 installed on the underfloor space 17 side. With such a configuration, the living room 10 can be air-conditioned from the underfloor space 17 side. In particular, when the air conditioner 300 is used for heating, the entire living room 10 can be warmed by utilizing the property that warm air rises.

[0059] In addition, when the space above the ceiling of the common space 14 is narrow, the construction may be carried out as shown in FIG. 13. Here, FIG. 13 is a schematic view showing a case where the air-conditioning air 210 is conveyed using the underfloor 17 with a configuration different from that of FIG. 12.

[0060] In FIG. 13, the storage ceiling 521 is regarded as the ceiling of the storage space 520 (common space 14), and the storage ceiling bag 522 is regarded as the ceiling back 16. When regarded in this way, a ceiling opening 122 is provided in the storage ceiling 521, an air conditioner 300 and an adapter 400 are installed in the storage floor bag 523, and a conveying fan 120 is installed in the storage ceiling bag 522. Further, the branch chamber 140 is installed in the underfloor 17. Furthermore, one end of the communication duct 135 is connected to the air outlet of the conveying fan 120 installed in the storage ceiling bag 522, and the other end is connected to the branch chamber 140 installed in the underfloor 17.

[0061] When the storage space 520 is divided into a storage ceiling bag 522 side and a storage floor bag 523 side by the storage ceiling 521 in this way, the storage ceiling 521 may be regarded as the ceiling, and the storage ceiling bag 522 may be regarded as the ceiling back 16 to construct the air-conditioning system 1000. In other words, if there is a ceiling that spatially divides the common space 14 into an upper part and a lower part, the ceiling may be regarded as the ceiling, and the upper space may be regarded as the ceiling back 16.

[0062] Even with such a configuration, the air-conditioning air 210 blown out from the conveying fan 120 can be conveyed from the side of the storage ceiling bag 522 regarded as the ceiling back 16 to the underfloor 17 side. In addition, even when the space above the ceiling of the common space 14 is narrow, the construction of the air-conditioning system 1000 can be facilitated.
