[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and their description will not be repeated.

[0016] Buildings that use a central air conditioning system and a 24-hour ventilation system have been known for some time. For example, Figure 1 shows a building that uses these systems.

[0017] Referring to FIG. 1, the building 100 is, for example, a two-story house, and a plurality of rooms are arranged in the indoor space. On the first floor of the house 100, occupant rooms 111, 112 and a non-occupant room 113 are arranged. The occupant room 111 is, for example, a living room, and the occupant room 112 is, for example, a private room such as a bedroom. The non-occupant room 113 is a passage room (corridor or entrance hall) with an entrance to a staircase 114. On the second floor (i.e., the top floor) of the house 100, a plurality of occupant rooms 115, 116 and a non-occupant room 117 are arranged. The occupant rooms 115, 116 are, for example, private rooms such as a bedroom. The non-occupant room 117 is a passage room (corridor) with an entrance to a staircase. In other words, the staircase 117 is an atrium that connects the first floor and the second floor, and the non-occupant room 117 on the second floor and the non-occupant room 113 on the first floor are connected to each other without a partition via the staircase 117. Therefore, these non-occupied rooms 113 and 117 form a single hall. An air conditioning control room 140 is provided facing the non-occupied room 117 located on the second floor.

[0018] The air-conditioning controlled room 140 is a room separated by a vertical wall of the house 100. The air-conditioning controlled room 140 is a room for sending conditioned air that has undergone heat exchange to a plurality of rooms in the house 100.

[0019] In this embodiment, "room" includes both habitable and non-habitable rooms, where "habitable room" refers to a room that is used continuously for purposes such as living, working, and recreation, and "non-habitable room" refers to a room other than a habitable room, excluding rooms used for sanitary purposes (e.g., toilets and bathrooms) and storage rooms.

[0020] A ceiling space 120 is formed between the first and second floors of the house 100, and between the second floor and the roof. A branch chamber 61 connected to a main duct 60 extending from an air conditioning control room 140 is provided in this ceiling space 120. The branch chamber 61 branches into a plurality of branch ducts 62. The branch ducts 62 are connected to air outlets 70 provided in ceiling partitions 121 of each room. This makes it possible to send conditioned air sent out from the air conditioning control room 140 to each of the rooms 111, 112, 115, and 116.

[0021] A ventilation control room 30 is provided on the second floor of the house 100. The ventilation control room 30 is a room separated by a vertical wall of the house 100. The ventilation control room 30 faces the non-occupied room 117, and is located facing the air conditioning control room 140 across the non-occupied room 117. A ventilation device 31 is provided in the ventilation control room 30. The ventilation device 31 is, for example, a central heat exchange ventilator, and is capable of exhausting and supplying air simultaneously. The ventilation device 31 has a function of supplying air (outside air) from an outdoor space to an air supply port 33 via an air supply duct 32 and sending it to the air conditioning control room 140, and a function of discharging air inside the building 100 (non-occupied rooms 113, 117) from an exhaust port 135 to the outdoors via an exhaust duct 134.

[0022] In this way, the air conditioning controlled room 140 and the ventilation controlled room 30 are formed in different rooms in the house 100. This allows for a wider range of options for the devices to be used in the air conditioning controlled room 40 and the ventilation controlled room 30, and also makes it easier to maintain each device.

[0023] On the other hand, the inventor has found, as a result of intensive research, that the configuration of Fig. 1 has the following problems. The exhaust ports 135 of the ventilation device 31 are provided in the non-occupied rooms 113 and 117 provided on the first and second floors, respectively. In this configuration, it is necessary to install the exhaust ports 135 in the non-occupied rooms 113 and 117, respectively, and to extend the exhaust duct 134 to the ventilation control room 30, which requires space for the duct and increases the number of installation procedures. Furthermore, the exhaust ports 135 are exposed to the ceilings of the non-occupied rooms 113 and 117, which reduces the design of the house 100. Furthermore, the exhaust air volume at the exhaust ports 135 is large, which may increase noise in the non-occupied rooms 113 and 117.

[0024] Therefore, as a result of extensive research, the inventors came up with the idea of ​​a house 10 as shown in Fig. 2. Fig. 2 is a diagram showing a building in which an air-conditioning controlled room according to this embodiment is used. The house in Fig. 1 and the house in Fig. 2 have the same basic configuration, but differ in the location where exhaust port 35 connected to ventilation device 31 is installed and the layout of exhaust duct 34. The following explanation will focus on the differences between Fig. 1 and Fig. 2.

[0025] Exhaust port 135 connected to ventilation device 31 is installed in the ceiling (top wall 46 in FIG. 3) of air conditioning controlled room 40. Next, air conditioning controlled room 40 of this embodiment will be described in detail.

[0026] <About the climate control room> Air conditioning controlled room 40 according to this embodiment will be described in detail with further reference to Figures 3 to 5. In Figures 3 to 5, the direction indicated by arrow A1 is referred to as the up-down direction, in Figure 4, the direction indicated by arrow A2 is referred to as the lateral direction, and in Figures 3 to 5, the direction indicated by arrow A3 is referred to as the forward direction, and the opposite direction is referred to as the rearward direction.

[0027] The air conditioning controlled room 40 generally comprises a room 41, an air intake port 33, an air conditioner 51, an air conditioning box 53, a blower 54, a main duct (air outlet) 60, and an exhaust port 35.

[0028] As shown in Figs. 3 and 4, the room 41 is surrounded by a pair of side walls 42, a rear wall 43, a front wall 44, a floor wall 45, and a top wall 46. The front wall 44 has an opening that contacts the non-occupied room 117. An openable door body 47 is provided in the opening. This makes it possible to open the door body 47 and perform maintenance on the air conditioning control room 40. The door body 47 is typically a hinged door, but may be, for example, a sliding door or a folding door. In addition, the room 41 is preferably formed of a soundproof wall to prevent internal sound from leaking out.

[0029] An air intake 48 is provided above the door body 47 to take in air from the non-occupied room 117. The air intake 48 directly takes in air from the non-occupied room 117, but also indirectly takes in air from indoor spaces such as the other non-occupied rooms 113 and the occupied rooms 111, 112, 115, and 116. The air intake 48 is provided with a so-called louver and includes a substantially rectangular frame body 49 and a plurality of slats 50 supported by the frame body 49. The slats 50 extend horizontally and parallel to the top wall 46.

[0030] With particular reference to FIG. 3, the air conditioner 51, the air conditioning box 53, and the blower 54 are arranged vertically on the door body 47 side, and the whole is covered by the housing 55 shown in FIG. 4. The housing 55 includes a front surface 56 facing the front wall 44, a rear surface 57 facing the rear wall 43 and provided at a position with a gap of the main duct 60, a floor surface 58 located on the floor wall 45, and an upper surface 59 protruding from the upper edge of the front surface 56 toward the rear surface 57. The air supply port 33 is arranged at the upper end of the rear surface 57. Therefore, the upper surface 59 does not extend to the rear surface 57 in the depth direction, but extends only to a midway position. The housing 55 may have a heat insulating material attached to its front surface to prevent condensation. The main duct 60 is provided between the rear surface 57 of the housing 55 and the rear wall 43.

[0031] The air supply port 33 takes in air from the outdoor space into the room 41. The air supply port 33 is provided at the tip of the air supply duct 32 that penetrates the top wall 46, and is provided at a position lower than the top wall 46. As shown in Figs. 4 and 5, the air supply port 33 is formed in a substantially box shape and includes an upper plate portion 33a that protrudes forward from the front of the air supply duct 32, a front plate portion 33b that extends downward from the front end of the upper plate portion 33a, and a lower plate portion 33c that protrudes forward from the rear lower end of the air supply duct 32. Openings are formed at the front end of the lower plate portion 33c and the lower end of the front plate portion 33b. From this opening, the air from the outdoor space sent into the air supply duct 32 is sent to the air conditioner 51.

[0032] The air conditioner 51 is, for example, a home wall-mounted air conditioner. The air conditioner 51 is attached to the upper side of the housing 55. As a result, the air conditioner 51 is attached to the approximately upper end of the housing 55 in the up-down direction. The air conditioner 51 includes an intake port 51a for taking in outside air and an exhaust port 51b for discharging the air sucked from the intake port 51a as conditioned air. The intake port 51a is provided at the top, and the exhaust port 51b is provided at the bottom. The air conditioner 51 is located below the air supply port 33. Since the intake port 51a of the air conditioner 51 is located at the top, air from the outdoor space can be efficiently taken in by the air conditioner 51 from the air supply port 33.

[0033] An air conditioning box 53 is provided below the air conditioner 51. The air conditioning box 53 sends the conditioned air sent out from the air conditioner 51 to the blower 54. A filter for purifying the air sent out from the air conditioner 51 is disposed in the air conditioning box 53, and the purified air is guided to the blower 54.

[0034] The blower 54 blows the conditioned air sent to the housing 55 toward the main duct 60. The blower 54 is, for example, a blowing fan. The blower 54 blows air toward the rear surface 57 of the housing 55.

[0035] The main duct 60 is an outlet that sends out the conditioned air that has undergone heat exchange by the air conditioner 51 to multiple rooms. One longitudinal end of the main duct 60 is connected to the blower 54 while maintaining airtightness, and the other longitudinal end is connected via a branch chamber 61 to a branch duct 62 (FIG. 1) that sends air to multiple rooms. The main duct 60 is provided so that it branches not only upward but also downward to send out conditioned air to the indoor spaces on the first and second floors. With this configuration, the air conditioning control room 40 itself can be made smaller, making it possible to reduce costs.

[0036] <Air conditioning air flow> The air flow in the house 10 will be described with reference to Figures 2 and 3. The arrows in Figure 3 indicate the flow of air and conditioned air. This air flow can occur not only when the air conditioner 51 is driven, but also when the air conditioner 51 is not driven.

[0037] As shown in Fig. 2, air from an outdoor space is supplied into the air conditioning control room 40 from the air supply port 33 via the air supply duct 32. As shown in Fig. 3, the air supplied to the air conditioning control room 40 is directly sucked in through the air intake port 51a of the air conditioner 51, heat converted, and discharged as conditioned air from the air exhaust port 51b of the air conditioner 51. The conditioned air passes through the air conditioning box 53 to be purified, and is sent to the blower 54. Furthermore, the conditioned air sent to the blower 54 passes through the main duct 60, and as shown in Fig. 1, passes through the branch chamber 61, is branched by a plurality of branch ducts 62, and the conditioned air is sent to each room from the air outlet 70.

[0038] As shown in Fig. 2, air conditioning controlled room 40 is adjacent to non-occupied room 117, and non-occupied room 117 and non-occupied room 113 on the first floor are connected to each other through an open atrium, and air on the first floor is also connected to air conditioning controlled room 40 on the second floor through non-occupied rooms 113, 117. Therefore, air from non-occupied room 117 is supplied to air conditioning controlled room 40 from air intake 48 of air conditioning controlled room 40. Furthermore, the air supplied to air conditioning controlled room 40 is exhausted to the outdoor space from exhaust outlet 35 via exhaust duct 34.

[0039] As a result, the air conditioning controlled room 40 of this embodiment can ventilate the indoor space while adopting a central air conditioning system. Also, since the air conditioning controlled room 40 is provided with an exhaust vent 35 for ventilation, the design of the house 100 can be improved. Furthermore, since the air conditioning controlled room 40 is a sound-absorbing room, the noise caused by exhaust can be reduced even if the exhaust vent 35 is provided.

[0040] <About modified examples> The inventors have found through extensive research that when the air conditioning control room 40 is configured in this manner, a "short circuit" may occur in which the conditioned air blown out from the air conditioner 51 is exhausted from the exhaust port 35, as shown by arrow S in Figure 6. The inventors have discovered that it is possible to prevent short circuiting by focusing on the following items.

[0041] That is, the items for suppressing short circuits are (1) to devise the arrangement of air intake 48, (2) to install shielding plate 59 on housing 55, and (3) to devise the shape of air intake 48. Each item will be described in detail.

[0042] (1) Regarding the placement of the air intake 48 First, the arrangement of the air intake 48 will be described. Fig. 7 is a schematic diagram of an air conditioning controlled room, showing the positional relationship of the air intakes, with Fig. 7(A) showing the case where the air intake is arranged at the top, and Fig. 7(B) showing the case where it is arranged at the bottom. In these figures, the same reference numerals as those in the air conditioning controlled room 40 of this embodiment are used.

[0043] In the air conditioning controlled room 40 in Fig. 7(A), from above, there are arranged in this order: exhaust port 35 that exhausts air from the air conditioning controlled room 40 to the outdoor space, air intake 48 that takes in air from the indoor space to the air conditioning controlled room 40, air supply port 33 that supplies air from the outdoor space to the air conditioner 51 (Fig. 3), and outlets (main duct 60) that blow conditioned air into each room. On the other hand, in the comparative example of the air conditioning controlled room 40 in Fig. 7(B), there are arranged in this order: exhaust port 35 that exhausts air from the air conditioning controlled room 40 to the outdoor space, air supply port 33 that supplies air from the outdoor space to the air conditioner 51 (Fig. 3), air intake 48 that takes in air from the indoor space to the air conditioning controlled room 40, and outlets (main duct 60) that blow conditioned air into each room.

[0044] A carbon dioxide measuring instrument 160 was installed near the outlet (main duct 60) from which the conditioned air was blown out to each room, and the carbon dioxide at the outlet (main duct 60) was measured. In Fig. 7(A), the carbon dioxide concentration at the outlet (main duct 60) was 1072.89 ppm, and in Fig. 7(B), the carbon dioxide concentration at the outlet (main duct 60) was 1112.15 ppm.

[0045] It was found that a configuration in which air intake 48 for taking in indoor air into air conditioning control room 40 is provided at the top (FIG. 7(A)), improved the carbon dioxide concentration by about 4% compared to a configuration in which air intake 48 is provided at the bottom (FIG. 7(B)). The air at air supply port 33, which supplies air from the outdoor space to air conditioner 51 (FIG. 3), has a low carbon dioxide concentration. Therefore, it was found that the arrangement in FIG. 7(A), in which the carbon dioxide concentration is low, allows air from air supply port 33 to reach the outlet (main duct 60) more efficiently. In other words, it was found that a configuration in which air intake 48 is provided at the top suppresses short circuiting.

[0046] (2) Shape of the housing 55 Next, the shape of the housing 55 will be described. As shown in Figs. 3, 4, and 7, the housing 55 has an upper surface 59 on its upper side. This upper surface 59 functions as a shielding plate for preventing the air conditioned by the air conditioner 51 from moving toward the exhaust port 35 (backflow of air). As shown in Fig. 5 in particular, the height position of the shielding plate 59 is disposed above the lower end height position of the front plate portion 33b of the air supply port 33, and the difference in height is H. Therefore, by providing the shielding plate 59, it is possible to prevent the air supplied to the housing 55 from the air supply port 33 from moving upward, and it is possible to suppress a short circuit.

[0047] (3) Shape of air intake 48 Finally, the shape of the air intake 48 will be described. Fig. 8 shows a modified example of the air intake 48. As shown in Fig. 8, the air intake 48 includes a frame body 49 and a plurality of slats 50A supported by the frame body 49. The plurality of slats 50A extend obliquely upward toward the exhaust outlet 35. This makes it possible to guide the air taken in from the air intake 48 into the air-conditioning controlled room 40 toward the exhaust outlet 35, thereby facilitating the discharge of the air taken in from the air intake 48 through the exhaust outlet 35.

[0048] In the present embodiment, the air-conditioning controlled room 40 has been described as being provided in the house 10, but the air-conditioning controlled room 40 may be provided separately as a standalone unit.

[0049] Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope. [Explanation of symbols]
