Abstract

PURPOSE: To prevent a frequent repetition of a prevention of an operation of a compressor by once stopping a refrigeration cycle in the case of operating an antifreezing of one heat exchanger in a refrigerating cycle apparatus having two user side heat exchangers and two compressors for one non-utility side heat exchanger and then controlling to function the one compressor as both the heat exchangers. CONSTITUTION: When an antifreezing deciding means decides an antifreezing as during operating, compressors 1, 2 are stopped. When the means decides that a detected temperature T22 or T23 is higher than an antifreezing eliminating temperature, a one compressor mode for selecting two heat exchanges 7, 8 for the one compressor is started, and a timer starts counting. When it decides that the antifreezing is not during operating in this state, the one compressor mode is continued for a predetermined time until the timer ends to count. Thereafter, the compressors 1, 2 are operated. When the antifreezing is operated during the one compressor mode, the compressor 1 or 2 is stopped. And when the antifreezing is eliminated, the one compressor mode is again started.
