ABSTRACT:
An integrated receiver/dryer-accumulator-internal heat exchanger for use in a vehicle HVAC system and a method of operation. The integrated receiver/dryer-accumulator-internal heat exchanger may include an accumulator portion having an accumulator inlet configured to be in fluid communication with an evaporator, and an accumulator outlet configured to be in fluid communication with a compressor; and a receiver/dryer portion mounted within the accumulator portion and having receiver/dryer inlet configured to be in fluid communication with a first portion of a condenser and a receiver/dryer outlet configured to be in fluid communication with a sub-cooler portion of the condenser. The integrated receiver/dryer-accumulator-internal heat exchanger allows for exchanging heat between the refrigerant in the accumulator portion and refrigerant in the receiver/dryer portion.
