Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2015152194
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device that can appropriately secure intended circulation amount of a refrigerant.SOLUTION: This refrigeration cycle device includes a compressor, a first heat exchanger, an expansion device, a second heat exchanger, a bypass flow passage, a switch and a control section. The compressor, the first heat exchanger, the expansion device and the second heat exchanger are interconnected sequentially in a flowing direction of a refrigerant in a circulation flow passage of the refrigerant. The bypass flow passage bypasses the expansion device between the first heat exchanger and the second heat exchanger and is connected to the circulation flow passage. The switch opens/closes the bypass flow passage. The control section opens the switch, when control amount of the expansion device reaches a first threshold value or larger that is approximately maximum amount with the switch closed.
