Title:
HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/171803
Kind Code:
A1
Abstract:
During a heating operation, heat is captured from both the air and the ground by operating both of the following as vaporizers: an atmospheric-heat-source heat exchanger (5a) for performing a heat exchange with the air as the heat source thereof; and a geothermal-heat-source heat exchanger (5b) for using geothermal heat as the heat source thereof. During a defrosting operation, a four-way valve (2) is switched, the atmospheric-heat-source heat exchanger (5a) is operated as a radiator, geothermal heat is captured by operating the geothermal-heat-source heat exchanger (5b) as a vaporizer, and the captured geothermal heat is collected in a principal circuit (10a) via an auxiliary circuit (10b).
