Abstract
An accumulator for use in a heat pump system accommodates the flow of refrigerant in first and second directions as the system heats and cools, respectively. The accumulator includes a body and a cap. The body includes an inlet for receiving refrigerant from a compressor and an outlet for sending refrigerant to the compressor. A first port communicates with a front end heat exchanger for receiving refrigerant from this heat exchanger when heating and for sending refrigerant to this heat exchanger when cooling. A second port communicates with a passenger compartment heat exchanger for sending refrigerant to this heat exchanger when heating and for receiving refrigerant from this heat exchanger when cooling. A reversing valve, disposed in the cap, moves between a first position when heating and a second position when cooling such that the accumulator can accommodate the flow of refrigerant in the either direction.
