It can be made smaller.

It is a figure showing the state which installed the air conditioning system which concerns on one embodiment of this invention in the high airtight highly insulated house. It is a figure showing the modification of this invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a state in which an air conditioning system 10 according to an embodiment of the present invention is installed in a highly airtight and highly insulated house 20. The air-conditioning system 10 includes an air-conditioning room 11 that performs air-conditioning. The air-conditioned air that has been air-conditioned in the air-conditioning room 11 is blown to a plurality of places in an indoor living space 21, for example, each room or hallway. An air conditioner 12 is installed in the air conditioning room 11. An example of the air conditioner 12 is an air conditioner, and one unit is installed in the air conditioning room 11. Although the air conditioning room 11 may be installed anywhere in the building, in the present embodiment, for example, it is provided on a part of the second floor. The air conditioning room 11 is partially opened with respect to the indoor non-residential space 22. The non-residential space 22 is, for example, an attic, a ceiling pocket, or a floor, and is open to the attic in this embodiment.

  The air conditioning system 10 also includes a plurality of conditioned air passages 13 for guiding conditioned air from the air conditioning room 11 to a plurality of places in the indoor living space 21. The conditioned air flow path 13 is configured by a duct, for example. One end portion of each conditioned air flow path 13 is disposed, for example, with respect to the air-conditioning chamber 11, and the other end portion corresponds to, for example, each air outlet provided in each place of the living space 21. It is arranged. In the air conditioning chamber 11, for example, a blower 14 is provided corresponding to each air conditioning air flow path 13 individually, and one end of each air conditioning air flow path 13 is individually connected to each air conditioning air flow path 13. Air-conditioned air is sent to each indoor location via In addition to the living space 21, the conditioned air flow path 13 may be arranged so as to guide the conditioned air to a non-residential space 22, for example, under the floor.

  For example, each air blower 14 is preferably arranged in the air conditioning chamber 11 with the suction port 14A facing downward. This is because the safety of the operation of the blower 14 can be ensured. Moreover, the air blowers 14 are arranged in a plurality in the height direction in the air conditioning chamber 11, for example. Although FIG. 1 shows the case where three blowers 14 are arranged side by side in the height direction, two or four or more may be arranged. The blowers 14 may be arranged in a row in the height direction, but may be arranged in a plurality of rows.

  The air conditioning chamber 11 is preferably provided with a partition member 15 for controlling the flow path of the conditioned air in the air conditioning chamber 11. The partition member 15 divides, for example, a blower area where each blower 14 is arranged and an air-conditioning area where the air conditioner 12 is arranged, and lengthens the path from the air conditioner 12 to the blower 14. Thus, the temperature unevenness of each blower 14 is reduced. Specifically, for example, it is preferable that at least the uppermost blower 14 among the blowers 14 is configured to reach the suction port 14A toward the upper side after the conditioned air is directed downward. . That is, the partition member 15 has, for example, a space below the suction port 14A of the blower 14 located at the uppermost position among the blowers 14 arranged in the height direction, from above and above the side portions. It is preferable to be provided so as to cover a part. It is more preferable that the length of the partition member 15 in the height direction is formed below the blowing port 14A of the blower 14 located second from the bottom.

  In addition, it is preferable that the air conditioner 12 is arrange | positioned at the side part upper side of the partition member 15 in the air-conditioning area | region partitioned by the partition member 15, for example. This is because the length of the conditioned air from the air conditioner 12 to the air inlet 14A of each blower 14 can be increased.

  The air conditioning system 10 further includes an outdoor air introduction means 16 for introducing outdoor air into an indoor non-residential space 22 where the air-conditioned room 11 is opened, and an indoor non-residential space 22 where the air-conditioned room 11 is opened. Living space air introducing means 17 for introducing the air in the living space. Thereby, in this air conditioning system 10, when each air blower 14 sends conditioned air to each place of the living space 21 and the air conditioning room 11 becomes negative pressure, outdoor air is introduced into the non-residential space 22 where the air conditioning room 11 is opened. Outdoor air is introduced through the means 16, and air in the living space is introduced through the living space air introducing means 17, mixed, and flows into the air conditioning room 11. This is because the outdoor air and the air in the living space can be sufficiently mixed before reaching the air conditioning room 11, and the temperature unevenness can be reduced.

  The outdoor air introduction means 16 is constituted by, for example, a duct whose one end communicates with the outdoors. The outdoor air introduction means 16 is also provided with a heat exchanger 16A to exchange heat between the air introduced from the outdoors and the exhaust air of the living space 21 exhausted by the exhaust means 19 described later. Is preferred. The living space air introducing means 17 is constituted by a louver provided on the ceiling of the living space, for example.

  Moreover, it is preferable that conditioned air is sent from the air-conditioned room 11 by the conditioned air recirculation means 18 to the indoor non-residential space 22 where the air-conditioned room 11 is opened. This is because the temperature unevenness can be further reduced. The conditioned air recirculation means 18 is constituted by a duct, for example. For example, a blower (not shown) is preferably connected to the conditioned air recirculation means 18.

  In addition, the air conditioning system 10 preferably includes, for example, an exhaust unit 19 that exhausts the air in the indoor living space 21 to the outside. The exhaust means 19 is comprised by the duct, for example. In the living space 21, conditioned air is sent through the conditioned air flow path 13 and is in a pressurized state, whereby a part of the air in the living space 21 is discharged outside as exhaust air through the exhaust means 19. It has come to be. The exhaust means 19 is provided with, for example, the heat exchanger 16A described above, and is configured to exchange heat between the exhaust air and the outdoor air introduced by the outdoor air introduction means 16. Is preferred. In addition to the living space 21, the exhaust means 19 may be arranged so as to discharge non-residential space 22, for example, air under the floor to the outdoors.

  For example, the air conditioning system 10 operates as follows. First, for example, the air in the air conditioning room 11 is air-conditioned by the air conditioner 12. That is, for example, the temperature and humidity of the air in the air conditioning chamber 11 are adjusted. The conditioned air conditioned by the air conditioner 12 is, for example, guided inside the air conditioning chamber 11 by the partition member 15 and detoured downward, and then sucked into each blower 14. The conditioned air sucked into each blower 14 is blown to each place of the living space 21 through each conditioned air flow path 13 by each blower 14, for example. Further, when conditioned air is blown by each blower 14, the air-conditioned room 11 becomes negative pressure, and outdoor air is introduced into the non-residential space 22 in which the air-conditioned room 11 is opened via the outdoor air introduction means 16. The air in the living space 21 is introduced through the living space air introducing means 17, mixed, and flows into the air conditioning room 11.

  As described above, according to the present embodiment, the outdoor air and the indoor living space 21 are mixed in the indoor non-residential space 22 so as to flow into the air-conditioning room 11. The air in the space 21 can be mixed before reaching the air conditioning chamber 11. Therefore, the temperature unevenness of the conditioned air, that is, the temperature unevenness of the living space 21 can be reduced. Moreover, since the outdoor air and the air of the living space 21 are mixed using the non-residential space 22, it is not necessary to increase the size of the air conditioning room 11 for mixing, and the size of the air conditioning room 11 is reduced. be able to.

  Moreover, if each air blower 14 is arranged in the air conditioning chamber 11 with the suction port facing downward, the safety of operation can be ensured.

  Furthermore, a plurality of blowers 14 are arranged in the height direction in the air conditioning chamber 11, and a partition member 15 is provided in the air conditioning chamber 11, so that the conditioned air is directed to at least the uppermost blower 14 among the plurality of blowers 14. If air is directed to the lower side and then reaches the suction port, the conditioned air flows from the bottom to the top in the vicinity of the blower 14, so that the blower 14 located on the upper side and the lower side are located. With the blower 14 that performs, the temperature unevenness can be further reduced.

  The present invention has been described with reference to the embodiment. However, the present invention is not limited to the above embodiment, and various modifications can be made.
