Abstract:
An accumulator for an air conditioning or refrigeration system comprising:a housing, said housing comprising an upper portion and a lower portion joined together to form a chamber; a high pressure inlet port for conveying a high pressure refrigerant from a condenser into the accumulator; a high pressure outlet port for discharging the high pressure refrigerant from the accumulator to an evaporator; a low pressure inlet port for conveying low pressure refrigerant from an evaporator into the accumulator; a low pressure outlet port for discharging the low pressure refrigerant from the accumulator to a compressor; and a vapor conduit tube for conveying the low pressure refrigerant in the accumulator to a heat exchanger disposed in the chamber, said heat exchanger comprising at least one tube having an interior, a internal end, an external end, at least one low temperature channel, and at least one high temperature channel, each channel extending through the interior of the tube, wherein the external end of the high temperature channel is connected to the high pressure inlet port, the external end of the low temperature channel is connected to the low pressure outlet port, the internal end of the low temperature channel is connected to the vapor conduit tube, and the internal end of the high temperature channel is connected to the high pressure outlet port.
