This shows 3 efficiency is lost by the refrigeration cycle for this case. The characteristic of the refrigerant heat transfer fluid used is important on efficiency. The following list gives the desired characteristics listed in rough order of importance. 1 The vapor pressure of the fluid must be in a reasonable range for the desired temperatures. A vapor pressure of 0.1 psia or 5000 psia would make the fluid undesirable. 2 The liquid cannot freeze at the lowest temperature met in the cycle. 3 A...
