Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2022033453
Kind Code:
A
Abstract:
To provide a refrigeration cycle device in which such a problem that a liquid phase refrigerant is sucked into a compressor when a refrigerant circuit is switched, can be suppressed.SOLUTION: A refrigeration cycle device 10 comprises a refrigerant circuit switching unit including a valve element portion 161a of an expansion valve 16a for heating. The refrigerant circuit switching unit can switch a first circuit and a second circuit in such a manner that the first circuit causing a refrigerant from which heat is dissipated in an indoor condenser 12 to flow into a receiver 15 and causing the refrigerant evaporated in an outdoor heat exchanger 18 to be sucked in a compressor 11, and the second circuit causing the refrigerant from which heat is dissipated in the outdoor heat exchanger 18 to flow into the receiver 15 and the refrigerant evaporated in an indoor evaporator 19 to be sucked in the compressor 11. When switching from the first circuit to the second circuit, the refrigeration cycle device executes switching preparation control for stopping the compressor 11 and closing an inlet side of the outdoor heat exchanger 18 by the valve element portion 161a.SELECTED DRAWING: Figure 1
