Document Type and Number:
Japanese Patent JP5868498
Kind Code:
B2
Abstract:
During heat applying operation, both an air-source heat exchanger 5a that exchanges heat with the atmosphere as a heat source and an earth-source heat exchanger 5b that uses geothermal heat as a heat source serve as evaporators to collect heat from the atmosphere and the geothermal heat. During defrosting operation, while a four-way valve 2 is switched to cause the air-source heat exchanger 5a to serve as a radiator, and the earth-source heat exchanger 5b to serve as an evaporator to collect the geothermal heat, and the collected geothermal heat is collected in the main circuit 10a via the sub-circuit 10b.
