Title:
HEAT PUMP DEVICE
Document Type and Number:
Japanese Patent JP3843852
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat pump device capable of raising pressure when performing ordinary operation without raising design pressure.
SOLUTION: This heat pump device is constituted in such a way that a compressor 15, a heat exchanger 16 on use side, a pressure reduction mechanism 17, and a heat exchanger 18 on a heat source side are sequentially connected to operate a high pressure breaker when high pressure is abnormal. It stores actual operation pressure of the high pressure breaker 24 which becomes stop pressure of the compressor 15. When pressure on a high pressure side exceeds reference pressure which is lower than actual operation pressure of the high pressure breaker 24, the compressor 15 is stopped without operating the high pressure breaker 24.
