Definitions

  • the pair of refrigerants 14 and 15 which form two layers in liquid receiver 13 at the lower evaporator tempera tures and a soluble solution at the higher evaporator temperatures, are selectively circulated in the system in response to the load thereon.
  • Valve 16 is shown in open position for outlet 18 and in closed position for outlet 17 to provide refrigerant 15 in the system.
  • Compressor 11 pumps refrigerant 15 through condenser 12 to insulated liquid receiver 13 where it separates into its respective leaving the liquid receiver becomes a direct function of the evaporator temperature.
  • the pair of refrigerants are mutually soluble at the higher portion of the operating temperature range for the evaporator but they are substantially mutually immiscible at the lower evaporator temperatures. Above a certain evaporator temperature,
  • a refrigeration system including a receiver, and an evaporator, a compressor and a condenser, a pair of refrigerants in said receiver, said refrigerants being at a first temperature range substantially immiscible and at a second temperature range substantially, mutually soluble, means for circulating a solution of said refrig erants through said system during said second temperature range, and expansion valve means between said condenser and said receiver whereby the circulating refrigerant solution entering the said receiver is pre-cooled to maintain the temperature of the refrigerant in said receiver as a function of evaporator temperature, and vary the composition of the circulating refrigerant.
