Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2023044278
Kind Code:
A
Abstract:
To control a supercooling degree, pressure, temperature or flow rate of a refrigerant by using a simple configuration.SOLUTION: A refrigeration cycle device includes: refrigerant valves 30, 31, 32 having first connection ports 30a, 31a, 32a to which first heat exchangers 12, 18 are connected, second connection ports 30b, 31b, 32b to which an inlet side of a gas liquid separator 15 is connected, third connection ports 30c, 31c, 32c to which a refrigerant passage is connected, and valve elements 302, 312, 322 switching communication states of the first connection ports, the second connection ports and the third connection ports and decompressing a refrigerant; and a control section 50 switching a first operation mode in which the refrigerant is condensed in the first heat exchanger and then caused to flow into the gas liquid separator through the refrigerant valves and a second operation mode in which the refrigerant is condensed in the first heat exchanger and then caused to flow out from the third connection port through the refrigerant valve, and controlling the refrigerant valves so that a supercooling degree of the refrigerant condensed in the first heat exchanger comes close to a target supercooling degree in the first operation mode and a pressure, temperature or flow rate of the refrigerant comes close to a target value in the second operation mode.SELECTED DRAWING: Figure 1
