Title:
HEAT PUMP SYSTEM
Document Type and Number:
Japanese Patent JP2023008047
Kind Code:
A
Abstract:
To provide a heat pump system that may perform simultaneous operation of an air heat pump device and a geothermal heat pump device so as to not only distribute work load, but also realize defrosting operation of the air heat pump device while maintaining a feeling of heating.SOLUTION: An air heat side heat exchanger 7 of an air heat pump device 1 and a geothermal heat side heat exchanger 24 of a geothermal heat pump device 2 are connected to a radiator 3 in parallel. An air heat side heat medium circulation path 14 of the air heat pump device 1 is provided with a bypass 17 that bypasses the radiator 3 and a switching valve device 18 that switches flow of heat medium between a radiator 3 side and a bypass 17 side. A control device 4 operates the switching valve device 18, and stops the flow of the heat medium from the air heat side heat exchanger 7 to the radiator 3 so that the heat medium circulates between the bypass 17 and the air heat side heat exchanger 7 when the air heat pump device 1 performs the defrost operation.SELECTED DRAWING: Figure 1
