Abstract
A HVAC system including a multi-function unit for conditioning and controlling the flow of refrigerant. The multi-function unit may be contained within a housing that houses a receiver/dryer, integral heat exchanger and thermal expansion valve.
Claims9
A housing for a vehicle HVAC system comprising:
- a receiver/dryer that receives refrigerant from a condenser,
- a heat exchanger that transfers heat with the refrigerant flowing from the receiver/dryer via an outlet tube, and
- a thermal expansion valve, mounted to the heat exchanger, that controls a flow of refrigerant to an evaporator and a compressor based upon a temperature and a pressure of a refrigerant flowing from the heat exchanger through the outlet tube.
A HVAC system for a vehicle comprising:
- a compressor;
- a condenser that receives refrigerant from the compressor;
- an evaporator that receives refrigerant from a thermal expansion valve;
- and
- a housing enclosing:
- a receiver/dryer that receives refrigerant from the condenser that flows through and is accumulated in the receiver/dryer,
- a heat exchanger that transfers heat from refrigerant flowing from the condenser to refrigerant flowing from the evaporator, and
- the thermal expansion valve that controls a refrigerant flow to the evaporator based upon a temperature and a pressure of refrigerant flowing from the heat exchanger to the compressor, wherein the thermal expansion valve is mounted to the heat exchanger and is fluidly connected to the heat exchanger and the receiver/dryer through an outlet tube.
