Abstract:
A vapor compression system comprising:a compressor for increasing the pressure and temperature of a heat transfer fluid;a condenser for liquefying the heat transfer fluid;an evaporator for transferring heat from ambient surroundings to the heat transfer fluid;a multifunctional valve having a first inlet and a second inlet and an outlet;a saturated vapor line connecting the outlet of the multifunctional valve to the inlet of the evaporator;a liquid line connecting the condenser to the first inlet of the multifunctional valve;a discharge line connecting the compressor to the second inlet of the multifunctional valve;a suction line connecting the evaporator to the compressor; anda temperature sensor mounted to the suction line and operatively connected to the multifunctional valve,wherein the saturated vapor line is of sufficient length to vaporize a substantial portion of the heat transfer fluid before the heat transfer fluid enters the evaporator.
