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.
A refrigeration circuit for providing economizer control comprising: said refrigeration circuit including a continuous fluid path serially including compressor means, discharge line means, condenser means, liquid line means passing through an economizer means, expansion means, evaporator means, and suction line means containing pressure sensing means; means for supplying refrigerant to said economizer means in a heat transfer relationship with said liquid line passing through said economizer means; and means for controlling said means for supplying refri...
