ABSTRACT:
A refrigerating system of the type used in supermarkets for refrigerating foods merchandised in refrigerated display cases, utilizes a control valve sensitive to pressures in a surge receiver and the liquid line. The valve opens whenever the receiver pressure drops below that of the liquid line more than a predetermined amount, to force hot gas from the compressor discharge line into the receiver. An elevation of the receiver pressure results, until the predetermined pressure differential between the liquid line and the receiver is re-established.
