To provide a refrigerating cycle device preventing enlargement of a composition for cold storage, and capable of efficiently carrying out cold storage and cold dissipation.
The refrigerating cycle device 12 is provided with a vapor compression type refrigerating cycle. A receiver 28 accumulating a liquid refrigerant is arranged in the refrigerating cycle. A reaction vessel 35 is connected to the receiver 28. The reaction vessel 35 can be changed over between a regenerator of refrigerant gas and an absorber of refrigerant gas. A vaporizer 25 heating the liquid refrigerant from the receiver 28 is arranged in a refrigerant passage between the receiver 28, and the reaction vessel 35 functioning as the absorber. An air conditioner ECU 41 operates the reaction vessel 35 as the regenerator to carry out cold storage, and it operates the reaction vessel 35 as the absorber to carry out cold dissipation.
