Description

[Detailed explanation of the invention] This invention is mainly used as air conditioning equipment in various offices.In detail, the indoor air sucked in from the intake window on the front of the aircraft body is exchanged for heat through a blower installed inside the aircraft body. A blower type air conditioner/heater configured to cool or heat through a device and blow out the cooled or heated air, and a blower type air conditioner/heater configured to cool or heat the air through a device, and a blower type air conditioner/heater installed at multiple locations indoors to receive the cooled or heated air blown out from the air conditioner. The present invention relates to a duct-type air-conditioning system that is comprised of a duct that distributes air flow to a ceiling outlet.

In conventional general equipment of this kind, only the cooling or heating air blown out from the air conditioner is sent into the duct to distribute and flow it, and the air conditioner is installed in multiple locations in the ceiling of the room. The air is blown downward into the room from the outlet, but this not only creates a temperature difference between the blow-off area and other areas, but also suppresses the discomfort caused by the blow-out air hitting the human body directly. Therefore, the blowing speed cannot be increased too much,
This causes the so-called short-circuit flow phenomenon in which the blown air is sucked into the air conditioner before it reaches the lower level of the room, causing a temperature difference between the top and bottom even in the blown air area, which affects the temperature distribution throughout the room. There was a problem that there were large variations, making it impossible to provide comfortable heating and cooling, and even harming the health of occupants in localized overcooling or overheating areas. Furthermore, if measures are taken to promote averaging of the room temperature by increasing the circulation flow rate (air volume) of indoor air, local overcooling or overheating areas are more likely to occur, and to avoid this, the heating and cooling equipment If the temperature is adjusted in this way, the operating efficiency of the air conditioner and heater will deteriorate, making it uneconomical.

In view of the above-mentioned circumstances, the present invention provides a ducted air-conditioning/heating system that can provide comfortable cooling/heating effects without causing local overcooling or overheating areas in the room even when the air conditioner is in full operation. have a purpose.

The duct air-cooling/heating device according to the present invention devised to achieve the above object has the configuration described in detail at the beginning, and has an intake that can be selectively opened and closed at a higher position and a lower position than the intake window of the air-conditioning/heating machine. The duct is characterized by a configuration in which a blower device is added that has ports and can send indoor air sucked in from these ports into the duct.

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, A is a blower-type air conditioner, which blows indoor air into the fuselage 2 through a blower 5 installed in the floor-standing fuselage 2 through an intake window 3 formed on the front of the fuselage. At the same time, this intake room air is cooled or heated by an indirect heat exchange effect with a heat medium flowing in a heat exchanger 4 installed in an inclined position in the aircraft body 2, and the cooled or heated air is It is configured to blow out through an upward duct 13. Reference numeral 6 denotes a ceiling duct built-in or arranged in the attic space, one end of which is connected to the cooling or heated air blowing duct 14 of the air conditioner A, and the duct 6 is installed at any plurality of locations on the ceiling surface of the room. The air outlet 13 is connected in communication with the air outlet 13.
Reference numeral 7 denotes a blower device installed on the side of the air conditioner A, which is installed at the upper end of the vertical duct 8 at a position higher than the intake window 3 of the air conditioner A and at the lower end of the vertical duct 8. Inlet ports 10 and 11 are provided at positions lower than the inlet window 3, respectively.
0 and 11 are equipped with opening/closing doors 10A and 11A, respectively, and both entrances 1 are opened via these opening/closing doors 10A and 11A.
0 and 11 can be selectively opened and closed, and a blower 9 is installed at the upper end of the vertical duct 8.
and is connected to the ceiling duct 6 via an inclined duct 12.

In the ducted air-conditioning/heating system configured as described above, during cooling, the lower air intake port 11 is closed, the upper air intake port 10 is opened, relatively high-temperature indoor air is drawn in from a high place in the room, and the air is passed through the inclined duct 12. During heating, the upper air intake port 10 is closed and the lower air intake port 11 is opened to draw in relatively low-temperature room air from a low place in the room, which is then passed through the inclined duct 12 to the ceiling duct. By sending the air into the ceiling duct 6, a plurality of air-fuel mixtures generated by the air conditioner A and mixed with the cold air or warm air fed into the ceiling duct 6 are generated, the temperature of which is higher than that of the cold air or the temperature of which is lower than that of the warm air. It is blown into the room from the air outlet 13.

As is clear from the detailed description above, according to the present invention, indoor air of a higher or lower temperature than the cold air or warm air generated by the air conditioner A is separately drawn in and mixed with the cold air or warm air. This allows a large amount of indoor air to be circulated, and the temperature of the large amount of circulating indoor air can be averaged in the duct 6 and then blown into the room, making it possible to maintain the same indoor heating and cooling temperature settings. When compared with the conventional example described above, it is possible to significantly reduce the temperature difference throughout the room without causing local overcooling or overheating. In addition, while the total circulation amount of indoor air is sufficiently large, the indoor air circulation amount of the air conditioner A itself can be small, so the air conditioner A can be made smaller and more efficient.
Economical operation is possible.

Overall, it has now become possible to economically realize heating and cooling effects that are both comfortable and beneficial for health.

Although the blower device 7 can be configured integrally with the air conditioner A, by configuring it separately as in the above embodiment, the shape of the room to be cooled and heated, the arrangement of furniture, etc., the size, etc. Not only can it be installed and used in an optimal position, but it also has the advantage of being able to implement the device of the present invention by adding means to an existing ducted air-conditioning system.
