RECEIVER PRESSURE CONTROL MEANS FOR REFRIGERATIONSYSTEMS OF THE ENERGY CONSERVATION TYPEABSTRACT OF THE DISCLOSUREA refrigerating system of the type used in super-markets for refrigerating foods merchandised in refrigerateddisplay cases, utilizes a control valve sensitive to pressuresin a surge receiver and the liquid line. The valve openswhenever the receiver pressure drops below that of theliquid line more than a predetermined amount, to force hotgas from the compressor discharge line into the receiver.An elevation of the receiver pressure results, until thepredetermined pressure differential between the liquid lineand the receiver is re-established.
