Title:
REFRIGERATING CYCLE DEVICE
Document Type and Number:
Japanese Patent JP3811116
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerating cycle device with a low cost and a high efficiency, by means of omitting a four-way valve which reverses a flow direction of a refrigerant that flows in an inner heat exchanger and an expander in an operational mode.
SOLUTION: In the refrigerating cycle device reversing the direction of the refrigerant which flows in the inner heat exchanger and the expander in the operational mode of the refrigerating cycle device using a carbon dioxide as the refrigerant, the refrigerating cycle device is constructed to put the inner heat exchanger and the expander into operation when the operational mode is that a temperature of a refrigerant outlet is relatively high, and not to put the inner heat exchanger and the expander into operation when the operational mode is that the temperature of the refrigerant outlet is relatively low.
