Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2017101897
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of downsizing a liquid-return flow rate adjusting part.SOLUTION: A refrigeration cycle device 1 includes an accumulator 17, a liquid-return flow pipe 18, a liquid-return flow rate adjusting part 19, a high-pressure sensor 20, a condensation liquid temperature sensor 21 and a control part 22. The accumulator 17 is provide on a main pipe 15 between a second heat exchanger 14 and a compressor 10. The liquid-return pipe 18 is connected to the accumulator 17 and the main pipe between the accumulator 17 and the compressor 10. The liquid-return flow rate adjusting part 19 is provided on the liquid-return pipe 18. The high pressure sensor 20 detects a pressure of refrigerant at a discharge port of the compressor 10. The condensation liquid temperature sensor 21 detects the temperature of the refrigerant at an outlet of the first heat exchanger 12. The control part 22 calculates a high-pressure saturation temperature being a saturation temperature of the refrigerant corresponding to the pressure detected by the high-pressure pressure sensor 20, and adjusts an opening of an expansion part 13 on the basis of a difference between the high-pressure saturation temperature and the temperature detected by the condensation liquid temperature sensor 21.SELECTED DRAWING: Figure 1
