Abstract:
A refrigeration system comprising:a compression device to compress a refrigerant to a high pressure, said compression device including a compressor suction and a compressor discharge; a heat rejecting heat exchanger for cooling said refrigerant; a hopper expansion device for reducing a hopper portion of said refrigerant to a hopper low pressure; a cylinder expansion device for reducing a cylinder portion of said refrigerant to a cylinder low pressure; a hopper liquid line valve positioned between said hopper expansion device and said heat rejecting heat exchanger; a cylinder liquid line valve positioned between said cylinder expansion device and said heat rejecting heat exchanger; a hopper heat exchanger, said refrigerant from said hopper expansion device exchanging heat with a hopper mix in said hopper heat exchanger; and a cylinder heat exchanger, said refrigerant from said cylinder expansion device exchanging heat with a cylinder mix in said cylinder heat exchanger.
