Abstract:
A vapor compression refrigeration system, comprising:a compressor having an inlet and an outlet; a condenser having an inlet and an outlet, the inlet of the condenser coupled with the outlet of the compressor; an expansion device having an inlet and an outlet, the inlet of the expansion device coupled to the outlet of the condenser; an evaporator feed line having an inlet and an outlet, the inlet of the evaporator feed line coupled to the outlet of the expansion device; and an evaporator coil having an inlet and an outlet, the inlet coupled to the outlet of the evaporator feed line, the outlet of the evaporator feed line coupled to the inlet of the compressor by a suction line, where at least one of the expansion device, a diameter of the evaporator feed line, and a length of the evaporator feed line are configured to convert a significant amount of a liquid refrigerant from a liquid form to a liquid and vapor mixture, and where at least one of the compressor, the expansion device, the expansion device outlet, and the evaporator feed line are configured to provide a volumetric velocity of the liquid and vapor mixture to the evaporator coil sufficient to provide an annular flow of the liquid and vapor mixture within the evaporator coil.
