Wall piercing type heat pump air conditioner

Abstract

Abstract PURPOSE:To realize the guick rise of cooling and heating at the time when air conditioning operation is stopped by a structure wherein auxiliary dampers are respectively provided on the way in an outside air influx passage and in an indoor air exhaust passage in order to prevent the outside air from flowing-in the room and the indoor air from flowing-out of the room. CONSTITUTION:The first auxiliary damper 20 to interrupt the indoor air exhaust passage 13 is provided at one end of a total heat exchanger 9 on the way in the indoor air exhaust passage 13. The second auxiliary damper 21 to interrupt the outside air influx passage 15 is provided at the other end of the total heat exchanger 9 on the way in the outside air influx passage 15. When air conditioning is perormed, a double wing damper 10 is in the state to close an outside air influx passsage duct 12 and a part of the outside air passing through the outside air influx passage 15 and a part of the indoor air passing through the indoor air exhaust passage 13 are heat-exchanged with each other at the total heat exchanger 9 in order to accomplish the heat recovery of the air-conditioned indoor air. When the cooling with the outside air is performed, the double wing damper 10 is changed-over so that the air flowed in from an outside air intake port 16 is led to an indoor blowoff port 5, while the air flowed in from an intake port 18 is led to a blowoff port 17 in order to be exhausted. In other words, when the air conditioning is stopped, the dampers 20 and 21 are changed-over so that the flows of a part of the outside air passing through the influx passage 15 and of a part of the indoor air passing through the exhaust passage 13 are both interrupted.
