Title:
REFRIGERATING CYCLE
Document Type and Number:
WIPO Patent Application WO/2003/019089
Kind Code:
A1
Abstract:
A refrigerating cycle capable of preventing vibration and noise from occurring at the time of opening and closing of a valve and increasing the stability of control in all load areas to be used, comprising a compressor for force−feeding refrigerant, a radiator for radiating heat from refrigerant compressed by the compressor, a high−pressure control valve (10) to regulate a pressure in a high−pressure line, decompress the refrigerant, and flow the refrigerant to a low pressure line, an evaporator for evaporating the refrigerant decompressed by the high−pressure control valve, a relief valve (11) for relieving the refrigerant from the high−pressure line to the low−pressure line when the high−pressure line is pressurized to a pressure beyond a set pressure, and a total closing prevention means for preventing both the high−pressure control valve (10) and the relief valve (11) from being totally enclosed.
