Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/126058
Kind Code:
A1
Abstract:
Provided is a refrigeration cycle device such that the disproportionation reaction of a refrigerant is suppressed. A refrigeration cycle device (100) in which a refrigerant, which can cause a disproportionation reaction, circulates through a compressor (1), a condenser, an expansion valve (4), and an evaporator in this order, the refrigeration cycle device being also equipped with: a first refrigerant flow path connecting the discharge side of the compressor and the condenser; a second refrigerant flow path connecting the condenser and the expansion valve; a third refrigerant flow path connecting the expansion valve and the suction side of the compressor; an injection unit (9); a pressure measuring unit (10); and a temperature measuring unit (11). The pressure measuring unit is mounted to the compressor or the first refrigerant flow path so as to measure the pressure of the refrigerant. The temperature measuring unit is mounted to the compressor or the first refrigerant flow path so as to measure the temperature of the refrigerant. The injection unit injects the refrigerant extracted from the second refrigerant flow path or the third refrigerant flow path into the compressor, the first refrigerant flow path, and/or the second refrigerant flow path if the measurement value of the pressure measuring unit and/or the temperature measuring unit exceeds an allowable value.
