As such, a low temperature, low pressure superheated gas refrigerant is drawn into compressor 12 through a conduit 24 from evaporator 22. The refrigerant is compressed and the resulting high temperature, high pressure superheated gas is discharged from compressor 12 to condenser 16 through a conduit 26.

  • the low pressure superheated gas then passes in heat exchange relation with heat exchanger 18, where it is further heated to increase the superheat of the gas and vaporize any residual liquid droplets that may pass tube bundle 32.

  • Heat exchanger 18 can also vaporize any residual liquid refrigerant that is drawn past tube bundle 32, which then allows for better use of heat transfer surfaces of bundle 32.
  • a method of increasing suction superheat in refrigeration system 10 includes supplying liquid refrigerant from condenser 16 to liquid suction heat exchanger 18, cooling the liquid refrigerant in liquid suction heat exchanger 18 against refrigerant vapor in evaporator 22, and supplying the cooled liquid refrigerant to evaporator 22.
