ABSTRACT:
A refrigerating system includes a first compartment used solely for cold storage, and a second compartment used either for cold storage or fermentation. First and second heat exchangers are disposed for cooling the first and second compartments, respectively. An outlet of the second heat exchanger communicates with an inlet of the first heat exchanger. A refrigerant distribution mechanism is operable in either a fermentation mode or a cold storage mode. In the fermentation mode, refrigerant is directed through first and second flow passages to the first and second heat exchangers, respectively, such that more refrigerant is delivered to the first heat exchanger than to the second heat exchanger; also, a heater in the second compartment is activated. In the cold storage mode, refrigerant is directed to the second flow passage but not to the first flow passage. An outlet of the second heat exchanger communicates with an inlet of the first heat exchanger, whereby in both the fermentation mode and the cold storage mode, refrigerant which flows through the second heat exchanger then flows through the first heat exchanger.
