Title:
COMPOSITE HEAT SOURCE HEAT PUMP DEVICE
Document Type and Number:
Japanese Patent JP2016038109
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a composite heat source heat pump device capable of repairing defrosting operation failure easily.SOLUTION: A composite heat source heat pump device includes: a heating circulation circuit having a heating circulation pump for circulating a circulation liquid L to a heat radiation terminal; a first heat pump circuit for heating the circulation liquid L via a first heating heat exchanger which is disposed in the heating circulation circuit and which uses geothermal heat; a second heat pump circuit for heating the circulation liquid L via a second heating heat exchanger which is disposed in the heating circulation circuit and which uses air heat; and a control device 6. It performs a heating operation for heating the circulation liquid L by actuating the second heat pump circuit and driving the heating circulation pump. The control device performs a defrosting operation for melting frost adhered to the air heat source heat exchanger of the second heat pump circuit by an operation of a forced defrosting switch.SELECTED DRAWING: Figure 5
