Document Type and Number:
Japanese Patent JP6811605
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat pump capable of reliably continuing operation of an engine driving compressor and/or motor compressor, even in a case where when a temperature of air subjected to heat exchange by a heat source side heat exchanger is extremely low, cooling operation is performed.SOLUTION: A heat pump is configured such that an engine drive compressor 11 and a motor compressor 12 share a refrigerant circuit, which stores the engine drive compressor 11 and the motor compressor 12 in a common package 102a to circulate refrigerant. The heat pump is configured to change condensation capacity of a heat source side heat exchanger 20, and in a case of performing cooling operation, when a temperature of air subjected to heat exchange in the heat source side heat exchanger 20 is not more than a preset temperature, make the condensation capacity of the heat source side heat exchanger 20 smaller than maximum condensation capacity.SELECTED DRAWING: Figure 2
