Abstract
A refrigeration circuit is provided in which economizer control is provided together with variable capacity control. Constant cooling is achieved by controlling an economizer cycle responsive to the suction pressure of the compressor. Additionally, compressor discharge temperature is controlled by controlling the portion of liquid refrigerant supplied to the interstage line.
