Precool/Subcool System and Condenser Therefor Abstract The apparatus 10 of the invention includes a pre- cooler (post heater) heat exchanger 24 and a subcooler heat exchanger 26 which are connected in fluid commu- nication with the refrigerant input and output, respectively, of the condenser 16 (evaporator 60) of a heat transfer system 12. A fluid, such as water, is forced through the subcooler heat exchanger 26 and then through the precooler (post heater) heat ex- changer 24 to be in a heat exchanging relationship with the refrigerant flowing therethrough. The method of the invention includes the step of regulating the flow rate of the water flowing through the apparatus 10 such that the refrigerant is pre- cooled to approximately its saturated-vapor state and subcooled when the system 12 is operating in a cooling mode and such that the refrigerant is post heated to at least a saturated-vapor state and subcooled when the system 12 is operating in a heating mode.
