AIR-COOLED HEAT PUMP UNIT
Document Type and Number:
Japanese Patent JP2015152266
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air-cooled heat pump unit capable of continuing a heating operation for a long time by suppressing frost formation on a heat source-side heat exchanger.SOLUTION: An air-cooled heat pump unit 1 includes: a heat pump circuit 11 provided with a compressor 12, a load-side heat exchanger 14, an expansion valve 15 and a heat source-side heat exchanger 16, for circulating a refrigerant; and a dehumidification circuit 21 in which the expansion valve 15 and the heat source-side heat exchanger 16 are connected in parallel with the heat pump circuit 11, and a dehumidification heat exchanger 23 is disposed. Both of the heat source-side heat exchanger 16 and the dehumidification heat exchanger 23 exchange heat between the refrigerant and the air, and are disposed in series to the air flow. The dehumidification heat exchanger 23 is disposed at the upstream side with respect to the heat source-side heat exchanger 16 in the air flow.
