ABSTRACT:
A cold storage and refrigeration system includes a single refrigerator, a plurality of cold storage and refrigeration units having evaporators, respectively, connected to the refrigerator for passage therethrough of a refrigerant when the refrigerator is in operation, a plurality of temperature sensors installed respectively in the cold storage and refrigeration units for detecting first and second levels of temperature respectively therein, and a control unit responsive to signals supplied from the temperature sensors for controlling the refrigerator in order to energize the latter in response to the detection of the first temperature level by one of the temperature sensors when the refrigerator is de-energized, whereby the refrigerant can flow through the evaporators simultaneously. With this arrangement, the refrigerator can remain de-energized for an increased interval of time during operation of the system, and hence consumes a reduced amount of electric power.
