Description

  The present invention relates to an air conditioning system.

  Previously, it was common to individually air-condition each room such as the living room and kitchen, but in conjunction with the progress of airtightness and high thermal insulation in the residence, a single air conditioner can be used for housing. It has been proposed to air-condition a plurality of residential areas such as corridors, stairs, entrances, toilets, bathrooms, etc. (for example, Patent Document 1).

JP 2011-174664 A JP 2012-57880 A

  The plurality of partitioned residential areas are lined up on the under floor space of the house across the residential floor, but the shape and occupied volume are not uniform. Therefore, if the number of air supply ports having substantially the same air supply capacity is arranged in each residential area by the number corresponding to the occupied volume of the residential area, the underfloor space can be used as an air supply area for conditioned air to each residential area. However, it has been found that even if the underfloor space is used as the air supply area while installing the number of air supply openings according to the occupied volume of the residential area, a difference occurs in the state of air conditioning in each residential area. For this reason, in an air conditioning system that performs air conditioning of a plurality of residential areas with a single air conditioner, a new air conditioning method that takes into account the characteristics of the residential areas has been required. In addition, there is a demand for cost reduction of the air conditioning system and simplification of the installation method.

In order to achieve at least a part of the problems described above, the present invention can be implemented as the following forms.
A residential air conditioning system having a plurality of partitioned residential areas,
An air conditioner room for receiving outside air from outside the house and return of air sent to the plurality of residential areas;
An air conditioner installed in the air conditioner room for air conditioning in the air conditioner room;
From the air conditioner room, the air-conditioned room air that has been air-conditioned by the air conditioner passes through an air supply compartment extending from the air conditioner room to an underfloor space communication point that communicates with an underfloor space on the first floor of the residence. An air-conditioning air delivery mechanism for delivering to the space under the floor,
Among the plurality of residential areas, a large-capacity residential area in which the occupied volume of the residential area is larger than the other residential areas is the communication of the air-conditioned room air sent out by the air-conditioned air delivery mechanism to the under-floor space. Using the underfloor space from the location to the plurality of air supply openings provided on the residential floor of the large-capacity residential area as a flow path, leading from the plurality of air supply openings, and introducing the introduced air-conditioned room air Return to the air conditioner room,
Among the plurality of residential areas, the other occupied area that is smaller than the large-volume residential area and partitioned from the large-volume residential area is configured to send the air-conditioned indoor air sent out by the air-conditioned air delivery mechanism below the floor. From the air supply port through a duct connected to the air supply port and extending from the space communication point to the air supply port provided in the dwelling floor of the other residential area, and a blower for supplying air in the duct The air-conditioning indoor air introduced is discharged into the large-volume residential area.

  (1) According to one aspect of the present invention, an air conditioning system is provided. This air conditioning system is a residential air conditioning system having a plurality of partitioned residential areas, and receives an air supply from outside the house and a return of air supplied to the plurality of residential areas. An air conditioner that is installed in the air conditioner room and performs air conditioning in the air conditioner room, and an air supply compartment that extends the air-conditioned room air that has been conditioned by the air conditioner from the air conditioner room to the floor of the dwelling. Then, an air-conditioning air delivery mechanism for delivering the air-conditioner room to the under-floor space is provided. Among the plurality of residential areas, a large-volume residential area in which the occupied volume of the residential area is larger than the other residential areas is the air-conditioned room air sent out by the air-conditioned air delivery mechanism to the underfloor space. Led from a plurality of air supply ports provided in the residential floor of the area, the introduced air-conditioned room air is returned to the air conditioner room, and the occupied volume from the large-volume residential area among the plurality of residential areas The other residential area which is divided from the large-capacity residential area is a duct which extends the air-conditioned room air sent out by the air-conditioned air delivery mechanism to an air inlet provided in the other residential area. Then, the air is introduced from the air supply port via a blower for supplying air, and the introduced air-conditioned room air is discharged to the large-volume residential area. In the air conditioning system of the above form, the large-capacity residential area where the occupied volume of the residential area is large and the other residential areas which are smaller than the residential area and partitioned from the large-capacity residential area are sent from the air-conditioned air delivery mechanism. The method of guiding the air-conditioning indoor air into the residential area is different. Therefore, there are the following advantages.

  In the large-capacity residential area, air-conditioned room air sent to the under-floor space is introduced from a plurality of air supply ports provided on the residential floor. In other words, the air-conditioned room air is introduced into the large-capacity residential area from a plurality of air supply ports, using the underfloor space itself as a flow path. In this large-scale residential area, the introduced air-conditioned room air is returned to the air-conditioner room, so the air flow in the residential area is promoted, and the air-conditioned room air sent to the under-floor space is provided on the residential floor. It is smoothly introduced into a large-volume residential area without receiving special resistance from a plurality of air supply ports. This means that the introduction of air-conditioned room air into a large-capacity residential area using the underfloor space itself as a flow path proceeds. On the other hand, if air-conditioning room air is introduced into a residential area with a small occupied volume (hereinafter referred to as a small-capacity residential area) using the underfloor space itself as a flow path, the underfloor space itself is used as the flow path. As the introduction of air-conditioned room air into the large-capacity residential area advances, the introduction of air-conditioned room air into the small-capacity residential area will be hindered. In addition, when the air-conditioning room air introduced from the air inlet through the underfloor space itself into the small-capacity residential area is discharged to the large-capacity residential area, it is resistant to air introduction from the inlet and the air outflow to the large-capacity residential area. It takes. For these reasons, the introduction of air-conditioned room air into small-capacity residential areas does not progress, and air conditioning in the small-capacity residential areas may be hindered.

  However, the air conditioning system of the above-described form is a fan that guides air in an air-conditioned room to a small-capacity residential area independently through a duct that extends to the air-feeding port of the small-capacity residential area. To promote ventilation in the duct. For this reason, the introduction of air-conditioned indoor air from the air inlet into a small-capacity residential area can be executed without receiving the influence of the introduction of air-conditioned indoor air into a large-capacity residential area and resistance due to air introduction / outflow. . Therefore, according to the air conditioning system of the above aspect, air conditioning indoor air is introduced into each residential area in consideration of the characteristics of the residential area, so that each residential area is provided with one air conditioner regardless of the size of the occupied space. Can be air-conditioned without any problems. In addition, for the introduction of air-conditioned indoor air into large-capacity residential areas, the underfloor space itself is used as a flow path, eliminating the need for ducts and blowers, reducing costs, and simplifying the construction method after omitting the installation of ducts. It is also possible to plan.

  (2) In the above-described air conditioning system, the other residential area (small-capacity residential area) includes the air supply port on a residential floor of the other residential area, and the air supply partition section and the underfloor space The air-conditioned room air can be introduced from the air supply port through the duct extending from the connection point to the air supply port. In this way, a duct for introducing air-conditioned room air into a small-capacity residential area can be installed in the underfloor space, so that the underfloor space can be effectively used.

  (3) In any one of the above-described air conditioning systems, the large-capacity residential area is configured such that the residential area ceiling is located in the vicinity of the air conditioner room and is separated from the underfloor space from the residential floor to the ceiling. Can be as high as possible. In general, in residential areas with high residential height, the occupied volume of the residential area increases because of the high ceiling, and air-conditioning room air is introduced more into the residential area (large-capacity residential area) that uses the underfloor space itself as a flow path. However, without being affected by this, air-conditioning indoor air can be introduced into a small-capacity residential area without hindrance, so that each dwelling area can be air-conditioned with one air conditioner regardless of the height of the dwelling.

  (4) In any one of the above-described air conditioning systems, the air supply section may extend from the air conditioner room to the floor under the residence adjacent to the large-volume residential area. In this way, since the underfloor space separating the large volume residential area and the residential floor is adjacent to the air supply section, the underfloor space below the large volume residential area can be effectively used as a flow path, and the large volume residential area Air conditioning room air can be introduced with high efficiency.

  In addition, this invention can be implement | achieved with various forms, for example, can be implement | achieved in aspects, such as a residence which has an air conditioning system.

It is explanatory drawing which shows the schematic structure of the residence 100 as embodiment of this invention typically by longitudinal cross-sectional view. It is explanatory drawing shown in combination with air derivation | leading-in, seeing the outline | summary of the room allocation of the 1st floor and the 2nd floor in the residence 100.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram schematically showing a schematic configuration of a residence 100 as an embodiment of the present invention in a vertical cross-sectional view, and FIG. It is explanatory drawing shown together with derivation | leading-in / out.

  As shown in the figure, the residence 100 of this embodiment is a high-air-tight and highly insulated two-story residence built on the foundation 101, and has a plurality of residential areas on each floor, and each residential area is Air conditioning is performed by an air conditioning system 120 described later. The allocation of the residence area can be set individually for each residence. In the present embodiment, for example, the following is performed. The dwelling 100 includes dwelling areas 210 to 214 on the first floor, and dwelling areas 221 to 223 on the second floor. The residential areas 210 to 214 on the first floor are arranged above the underfloor space with the underfloor space 111 and the dwelling floor 112 formed on the foundation 101 being separated. As shown in FIG. 2B, the residential area 210 includes an entrance area 210a, a first-floor corridor area 210b, and a staircase area 210s in which stair steps S are arranged, and a part of the first-floor corridor area 210b and the staircase area 210s. In the area, a so-called atrium structure is adopted in which the ceiling reaches the ceiling on the second floor. Therefore, the residential area 210 has a higher residential area height from the residential floor 112 to the ceiling than the other residential areas 211 to 214 on the first floor, and extends to the lower part of the air conditioner room 121 across the ceiling 108. It has become. Such a high-ceiling residential area 210 may be a so-called shared residential area having a living room and a kitchen together with a staircase area 210s on the first floor. The residential areas 211 to 213 can be used as a living room, a guest room, and the like, and the residential area 214 may include a bathroom, a washroom, and the like from the relationship of the plan view position. These residential areas 210 to 214 are partitioned by residential inner and outer walls as the housing constituent base material and ceilings of the respective residential areas. Since the residential areas 211 to 213 are used as living rooms, guest rooms, and the like, and the residential area 210 includes the above-described areas, the residential area 210 has a volume occupied by another residential area. It is made larger than the area | region 211-213.

  The second-floor residential areas 221 to 223 can be used as child rooms, bedrooms, and the like, and are aligned with the second-floor residential area 210 including the staircase area 210s and the second-floor corridor area 220b (see FIG. 2A). ). Even in these residential areas 221 to 223, they are partitioned by the inner and outer walls of the house as the housing constituent base material and the ceiling of each residential area. For example, the back side (right side of the drawing) of the first floor corridor area 210b can be a toilet or a bathroom, and the back side of the second floor corridor area 220b can be a toilet.

  The dwelling 100 has an air conditioning system 120 in the attic 110 between the roof 109 and the ceiling 108 on the second floor. The air conditioning system 120 includes an air conditioner room 121, an air conditioner 140, and an outside air introduction system 150. The air conditioner room 121 is formed separately from each residential area such as the residential area 210 described above, and the inner wall thereof is covered with a heat insulating material, and the heat of air conditioned by the air conditioner 140 described later is leaked to the outside. I am trying not to. The air conditioner room 121 has a partition plate 122 in the room. The partition plate 122 divides the internal space of the air conditioner room 121 into an intake side and an air conditioning side. In addition, the air conditioning system 120 includes an air supply partition 113 that extends from the air conditioner room 121 to the underfloor space 111. This air supply section 113 communicates with the air conditioning side area of the air conditioner room 121 where the air conditioner 140 is installed at the upper end side, and communicates with the underfloor space 111 at the underfloor space communication point 114 on the lower end side. It extends from the air conditioner room 121 to the underfloor space 111 adjacent to the residential area 210. The air-conditioning system 120 supplies air-conditioned room air CA that has been air-conditioned by the air-conditioner 140 in the air-conditioner room 121 to a plurality of motor-driven air blowers 123a on the upper end side of the air-feeding section 113 and air-feeding air. The air is blown from the air conditioner chamber 121 to the underfloor space 111 through the air supply partition portion 113 by a plurality of motor-driven air blowers 123b on the lower end side of the partition portion 113. That is, the air supply partition section 113 constitutes an air-conditioned air delivery mechanism according to the present invention in cooperation with the plurality of air blowers 123a and 123b at the upper and lower ends. For the maintenance of the air conditioning system 120, a storage-type staircase following the attic 110 is used. In this case, the air conditioner room 121 of the air conditioning system 120 is not limited to the attic 110 but can be installed at an appropriate location of the residence 100 where the air supply section 113 can be secured.

  The air conditioner room 121 divides the outside air by the outside air introduction system 150, which will be described later, and the return of the air that has been supplied to the residential area 210 (air-conditioned indoor air CA) as will be described later. Received on the intake side partitioned by 122. The air conditioner 140 obtains a mixture of the air that has passed over the partition plate 122 of the air conditioner room 121, that is, the outside air introduced from the outside air introduction system 150 and dust-removed, and the air-conditioned room air CA that has been returned as described later. It is a commercially available air conditioner that air-conditions to a target temperature, and blows out air-conditioned air (air-conditioned air-conditioned room air CA). An outdoor unit (not shown) of the air conditioner 140 is installed outside the residence 100. The outside air introduction system 150 includes a heat exchanger 155 and an air filter 156 in the outside air introduction pipe 154 from the outside air suction part 151 installed on the outer wall of the residence to the connection part 153 of the air conditioner room 121. The heat exchanger 155 exchanges heat between air flowing through an exhaust pipe 157 (to be described later) and air passing through the outside air introduction pipe 154 to reduce the energy loss of air conditioning by the air conditioner 140. Here, the air conditioning target temperature and the total air volume will be briefly described.

The air conditioning system 120 can have substantially the same specifications as the air conditioning system proposed in Japanese Patent Application Laid-Open No. 2011-174673. That is, the air conditioner 140 has a temperature difference within 5 degrees Celsius between the target temperature of the air conditioner room 121 and the target temperature of the above-described residential space that is the air conditioning target, In some cases, the air in the air conditioner room 121 is air-conditioned with a temperature difference within 10 degrees Celsius. The air-conditioning system 120 sends the air-conditioned air-conditioned room air CA to the air-feeding section 113 at a flow rate of 100 to 5,000 m 3 / h by the air blower 123a, and keeps the floor under the floor by the air blower 123b with almost the same flow rate. It sends out from the space communication place 114 to the underfloor space 111. In this way, by blowing air-conditioned air at a large flow rate, the temperature of each residential area is appropriately maintained to ensure comfort.

  Next, the introduction configuration of the air-conditioned air-conditioned room air CA to the residential area of each floor, the return structure to the air conditioner room 121, and the state of air introduction / discharge in each residential area will be described.

  The residential area 210 on the first floor includes an air supply port 115 and a motor-driven suction fan 116 on the residential floor 112, and a return port 117 and a motor-driven suction fan 118 on its ceiling 108. A plurality of air supply openings 115 and suction blowers 116 are installed on the residential floor 112 as a pair. The air supply openings 115 define the air sucked from the underfloor space 111 by the suction blowers 116, that is, the air supply partition 113. The conditioned air-conditioned room air CA sent from the air conditioner room 121 to the under-floor space 111 (specifically, the under-floor space 111 a occupying the lower side of the residential area 210) is introduced into the residential area 210. The return port 117 extends through the ceiling 108 of the residential area 210 to the inside of the air conditioner room 121, specifically to the intake side of the air conditioner room 121 divided by the partition plate 122, and the suction blower 118 sucks from the residential area 210. The air, that is, the air-conditioned room air CA introduced into the residential area 210 from the air supply port 115 is forcibly returned to the intake side of the air-conditioner room 121. The return air RA thus returned is subjected to air conditioning by the air conditioner 140 as described above together with the outside air from the outside air introduction system 150. In the present embodiment, considering that the occupied volume of the residential area 210 is large, four pairs of the air inlet 115 and the suction blower 116 are installed in the residential area 210. Considering the occupied volume of the area 210, it may be 5 pairs or more, or 2 to 3 pairs. In addition, since the air-conditioned indoor air CA is sent out to the underfloor space 111a by the air blower 123b, the air-conditioned air-conditioned indoor air CA can flow into the residential area 210 from each air supply port 115. Therefore, the suction blower 116 may be omitted for some or all of the plurality of air supply ports 115.

  Each of the residential areas 211 to 214 on the first floor is provided with an air inlet 115 on the residential floor 112 occupied by each residential area, and on the inner wall of the residential area 210 and the outlet 130 and A motor-driven suction blower 131 is provided. Since each of the residential areas 211 to 214 has a smaller occupied volume than the residential area 210, the air inlet 115 is set to one. In addition, each of the residential areas 211 to 214 includes ducts 211 d to 214 d and a motor-driven in-duct fan 119 in the underfloor space 111 below the residential floor 112. The ducts 211d to 214d are provided with heat insulation properties, and are based on an underfloor space communication point 114 between the air supply section 113 and the underfloor space 111a that occupies the lower side of the residential area 210, and each of the residential areas 211 to 214 from the communication point. It extends to underfloor spaces 111b to 111e occupying the lower part of the residential area, and is connected to the air blower 123b at the underfloor space communication point 114, and is connected to the air supply port 115 in each residential area. In this embodiment, the duct 213d is branched from the duct 212d and extends to the air inlet 115 of the residential area 212. However, the duct 213d is also extended independently from the underfloor space communication point 114 to the air inlet 115. Also good.

  The in-duct air blower 119 is disposed in the duct below the air supply port 115, and works with the air blower 123b to supply air in the ducts 211d to 214d. Accordingly, each of the residential areas 211 to 214 includes the air-conditioned air-conditioned indoor air CA sent to the under-floor space 111a occupying the lower part of the residential area 210 via the air supply partition 113, and the duct corresponding to each residential area. The air-conditioned air-conditioned room air CA introduced through 211d to 214d and the in-duct fan 119 of each duct is introduced from the outlet 130 to the residential area 210 by the suction fan 131. In introducing air-conditioned air-conditioned room air CA through the ducts 211d to 214d and the blower 119 in the duct, the air blower 123b in the underfloor space communication point 114 is also driven. If the introduction of the air CA is performed without hindrance, the air blower 123b on the base point side of the ducts 211d to 214d may be omitted. On the contrary, if the air blower 123b on the base point side of the ducts 211d to 214d can introduce the air-conditioned indoor air CA without any trouble, the blower 119 in the duct on the air supply port 115 side may be omitted. Moreover, since air-conditioned air-conditioned indoor air CA has been introduced into the residential areas 211 to 214 from the air supply port 115 by the blower 119 in the duct, the suction blower 131 that attempts air outflow to the residential area 210 is as follows. , May be omitted.

  Each of the residential areas 221 to 223 on the second floor includes an air inlet 115 and a suction blower 116 paired therewith on the second floor 231 occupied by each residential area. The air-conditioned indoor air CA that has been conditioned is introduced from the air inlet 115 by the suction fan 116. The residential area 221 includes an exhaust port 170 on the ceiling 108 and a motor-driven suction blower 172 that is paired with the exhaust port 170, and the air-conditioned indoor air CA introduced into the residential area 221 is exhausted by the suction fan 172. The air is exhausted from 170 to the exhaust pipe 157 of the outside air introduction system 150. In the residential areas 222 to 223, the housing inner wall, which is a partition with the residential area 210 on the second floor, is provided with an outlet 130 and a motor-driven suction blower 131 paired therewith, The air-conditioned indoor air CA introduced into the area is discharged to the residential area 210. Introduction of the conditioned air-conditioned room air CA into the second floor underfloor space 232 can be achieved by various methods, for example, from one air blower 123a of the air conditioner room 121 to the second floor underfloor space 232, or an air supply section. A duct is extended from the section 113 to the second floor underfloor space 232, and the conditioned air-conditioned room air CA is guided to the second-floor underfloor space 232 through the duct, and the conditioned air-conditioned room air CA is sent from the air inlet 115 to the residential areas 221 to 221. 223. In addition, a duct may be extended from one air blower 123a or the air supply section 113 included in the air conditioner room 121 to the second-floor space 232, and the duct may be connected to the air supply port 115 of each residential area. In addition, the outlet area 130 and the suction fan 131 may be provided on the ceiling of the residential area 211 on the first floor, and the conditioned air-conditioned room air CA may be introduced from the residential area 211 to the second floor underfloor space 232.

  As described above, in the air conditioning system 120 included in the residence 100 according to the present embodiment, the living area 210 has a high residential area height from the residential floor 112 to the ceiling 108 and has a large occupied volume because of the aerial form according to the residential specifications. In the living area of the air-conditioned room air CA sent out to the underfloor space 111 in the first-floor residential area divided alongside the residential area 210 and having a smaller occupied volume than the residential area 210 The way of guiding was different. First, for the residential area 210, the air-conditioned air-conditioned room air CA sent from the air conditioner room 121 to the under-floor space 111a through the air-supplying section 113 is used as a flow path with the under-floor space 111a itself below the residential area 210 as a flow path. It uses and guides from the plurality of air supply openings 115 of the residence floor 112. Although the residential area 210 has a high residential area height and a large occupied volume because of the atrium structure, the introduced air conditioning room air CA is forcibly returned to the air conditioner room 121 from the return port 117 of the ceiling 108 by the suction fan 118. ing. For this reason, since the air flow from the residential floor 112 side to the ceiling 108 side is promoted in the colonnade-shaped residential area 210, the conditioned air-conditioned indoor air CA sent to the underfloor space 111a is supplied to the respective floors. It is smoothly introduced into the high ceiling dwelling area without receiving any special resistance from the air vent 115. That is, the introduction of the air-conditioned room air CA into the residential area 210 using the underfloor space 111a itself as a flow path proceeds. Moreover, the introduction of the air-conditioned indoor air CA into the residential area 210 is further advanced by the suction blower 116 paired with the air supply port 115.

  On the other hand, for the small-occupied residential areas 211 to 214 partitioned side by side in the residential area 210, each of the residential areas 211 to 214 from the underfloor space communication point 114 between the underfloor space 111 and the air supply partition section 113. In the ducts 211d to 214d extending to the air inlet 115 in the residential area, the air-conditioning room air CA is guided independently, and the duct ventilation is promoted by the in-duct air blower 119 and the air blower 123b or by one air blower. . Therefore, the air conditioning system 120 of the present embodiment has the following advantages.

  Temporarily, the introduction of the air-conditioning indoor air CA into the small-occupied residential areas 211 to 214 partitioned alongside the residential area 210 is performed using the underfloor spaces 111b to 111e below the residential areas 211 to 214 as flow paths. Then, the air-conditioned indoor air to the residential areas 211 to 214 is equivalent to the amount that the introduction of the air-conditioned indoor air CA into the residential area 210 using the underfloor space 111a itself as a flow path proceeds on the air supply section 113 side. This will hinder the introduction of CA. In addition, when the air-conditioning indoor air CA introduced from the air supply port into the residential areas 211 to 214 through the underfloor spaces 111b to 111e itself is discharged from the outlet 130 to the residential area 210, air is introduced from the air supply opening 115. Resistance is applied to the outflow of air from the outlet 130 to the residential area 210 such as undercut. For these reasons, the introduction of air-conditioning indoor air CA into the residential areas 211 to 214 does not proceed, and air conditioning in the residential areas 211 to 214 may be hindered. However, since the air conditioning system 120 of this embodiment uses the ducts 211d to 214d and the blower 119 in the duct to introduce the air conditioning indoor air CA into the residential areas 211 to 214 as described above, the air conditioning system 120 to the residential areas 211 to 214 is used. The air-conditioning room air CA can be introduced from the air supply port 115 without receiving the influence of the introduction of the air-conditioning room air CA into the residential area 210 and the resistance due to air introduction / outflow. Therefore, according to the air conditioning system 120 of the present embodiment, the introduction of the air-conditioning indoor air CA into each residential area is not considered in consideration of the characteristics of the residential area. The area can be air-conditioned with one air conditioner 140 without any trouble. In addition, for the introduction of the air-conditioned indoor air CA into the residential area 210, the underfloor space 111a itself is used as a flow path, so that a duct and a blower are unnecessary, and the construction method is simplified through cost reduction or omission of the duct installation. Can be achieved.

  In the residence 100 of the present embodiment, since the residential area 210 is in a blow-off form, the ceiling 108 of the residential area 210 is located in the vicinity of the air conditioner room 121, so that the return port 117 and the suction blower 118 are connected to the air conditioner room 121. The inflow of the return air RA progresses, and the air flow from the residential floor 112 side to the ceiling 108 side in the residential area 210 is further promoted. For this reason, the introduction of the air-conditioning indoor air CA to the residential area 210 using the underfloor space 111a itself as a flow path further proceeds, but without being affected by this, the residential areas 211 to 214 have ducts 211d to 214d and a duct. The air blower indoor air CA can be introduced without any trouble by the inner blower 119. Therefore, according to the air conditioning system 120 of the present embodiment, each residential area can be air-conditioned with no trouble by the single air conditioner 140 regardless of the height of the residence.

Here, the state of air introduction by the air conditioning system 120 of the present embodiment will be described in association with the analysis result using the ventilation network calculation method. The ventilation network calculation method is established as a method for calculating and calculating by replacing the pressure resistance at the time of air supply with the resistance of the electric circuit and replacing the air volume with the current value. With this ventilation network calculation method, the amount of air blown from the air inlet 115 in the residential area 210 of FIG. 2 and the amount of air blown from the air inlet 115 in the residential area 211 were calculated. In calculating the ventilation network, the resistance when air flows in the order of the air inlet 115 → the residential area 210 → the return outlet 117 and the air inlet 115 → the residential area 211 → the outlet 130 → the residential area 210 → the return outlet 117 The resistance at the time of air flow was incorporated into the ventilation network calculation. And about the case where air is supplied from the air inlet 115 via the underfloor space 111b to the residential area 211 without using the duct 211d, and the case where air is supplied from the air outlet 115 using the duct 211d. Ventilation network calculation was performed to calculate the air blowing rate. For the residential area 210, the amount of air blown from each of the four air inlets 115 was calculated. As a result, when air is supplied from the air inlet 115 via the underfloor space 111b without using the duct 211d in the residential area 211, the amount of air blown from the air outlet 115 of the residential area 211 is 38.30 m 3 / h. In this case, the amount of air blown from each air inlet 115 of the residential area 210 was 240.3 m 3 / h. On the other hand, the amount of air blown from the air inlet 115 of the residential area 211 when air is supplied from the air outlet 115 using the duct 211d to the residential area 211 is 200 m 3 / h. The amount of air blown from each air supply port 115 in the area 210 was also 200 m 3 / h. From this result, according to the air conditioning system 120 of this embodiment, in addition to being able to air-condition each residential area with a single air conditioner 140 regardless of the height of the house and the size of the house, Regardless of the height and volume, it can be said that the air-conditioning indoor air CA can be introduced into each residential area with a single blown air amount by one air conditioner 140. This means that the air-conditioning room air CA can be introduced into each residential area with the amount of blown air intended by one air conditioner 140 regardless of the height of the house and the size of the volume.

  In the air conditioning system 120 of the present embodiment, the air supply section 113 extends from the air conditioner room 121 to the underfloor space 111 adjacent to the residential area 210, so that the floor below the residential area 210 and the residential floor 112 is separated. The space 111a and the air supply section 113 are adjacent to each other. Therefore, according to the air conditioning system 120 of the present embodiment, the air-conditioning room air CA is quickly sent from the air supply partition 113 to the underfloor space 111a below the residential area 210, and the underfloor space 111a flows effectively and immediately. By using it as a road, the air-conditioned room air CA can be introduced into the residential area 210 with high efficiency.
