Title:
排熱回収式空気調和装置
Document Type and Number:
Japanese Patent JP6529663
Kind Code:
B2
Abstract:
An exhaust heat recovery type of air-conditioning apparatus includes: an air-conditioning-side refrigerant circuit including a first flow switching device, a second flow switching device, and an exhaust-heat recovery heat exchanger connected in parallel to an outdoor heat exchanger and an indoor heat exchanger; and a refrigeration-side refrigerant circuit. The first flow switching device causes the outdoor heat exchanger to communicate with one of a discharge side and a suction side of a first compressor through a pipe. The second flow switching device causes the indoor heat exchanger to communicate with one of the discharge and suction sides of the first compressor through a pipe. The exhaust-heat recovery heat exchanger is connected to the suction side of the first compressor through a pipe, and causes heat exchange between refrigerants. Because of the above configuration, the exhaust heat recovery type of air-conditioning apparatus can use exhaust heat in any of operation modes.
