ABSTRACT:
The air conditioning system contains a refrigerant and comprises a compressor having an inlet and an outlet, a condenser having an inlet and an outlet, an evaporator having an inlet and an outlet and a suction conduit connecting the outlet of the evaporator to the inlet of the compressor where the refrigerant returns to the compressor as a low pressure vapor. A discharge conduit is provided which connects the outlet of the compressor to the condenser where upon removal of heat of the vapor, the gas becomes a high pressure liquid refrigerant. A liquid conduit having an injector and restrictor connects the outlet of the condenser to the inlet of the evaporator. An accumulator having an inlet port and an outlet port is interposed in the suction conduit. A liquid discharge port is also provided in the accumulator. A recirculating conduit connects the discharge port to the liquid conduit. The accumulator contains a baffle or other means which helps to separate the refrigerant vapor from the refrigerant liquid, whereby the vapor is directed to the inlet of the compressor through the suction conduit. The separated liquid is stored in the accumulator and is thereafter recirculated through the discharge port and the recirculating conduit to the liquid conduit and to the evaporator thereby bypassing the compressor and the condenser. The recirculation is via the injector which utilizes the velocity of the refrigerant in the liquid conduit to draw refrigerant from the accumulator.
