Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2017138037
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device preventing pressure at a high-pressure side of refrigerant from increasing during a heating operation, without being provided with a receiver.SOLUTION: A refrigeration cycle device includes a compressor, a four-way valve, a first heat exchanger, a first expansion part, a second heat exchanger, a gas-liquid separator, a main piping, a suction pressure sensor, a discharge pressure sensor, a first temperature sensor, a second temperature sensor, a blower and a control part. The control part adjusts an aperture of the first expansion part so that a superheating degree as a difference between a temperature of refrigerant detected by the first temperature sensor and a low-pressure saturated temperature becomes a prescribed target superheating degree, during a cooling operation, and adjusts the aperture of the first expansion part so that a supercooling degree as a difference between a high-pressure saturated temperature and a temperature of refrigerant detected by the second temperature sensor becomes a prescribed target supercooling degree, during a heating operation.SELECTED DRAWING: Figure 1
