Abstract
An air conditioning system for a vehicle includes an accumulator/dehydrator (A/D) disposed in the suction fluid line for accumulating refrigerant and a heat transfer jacket surrounds the A/D for exchanging heat with the A/D and the refrigerant therein. The heat transfer jacket may define a space between an inner wall of the A/D and an outer wall spaced therefrom with a heat transfer media disposed in the space for cooling by extracting heat from the refrigerant in the A/D. Alternatively, the jacket is defined by a double walled sleeve surrounding the A/D and defining the space for the heat transfer media. Yet another alternative is for the heat transfer jacket to comprise a thermoelectric device.
Claims10
An air conditioning system for a vehicle comprising:
- a compressor for compressing a refrigerant,
- a condenser for condensing the refrigerant,
- an evaporator for evaporating the refrigerant,
- a discharge fluid line interconnecting the compressor and said condenser,
- a liquid fluid line interconnecting said condenser and said evaporator,
- a suction fluid line interconnecting said evaporator and said compressor,
- an accumulator/dehydrator (A/D) disposed in said suction fluid line for accumulating refrigerant, and
- a heat transfer jacket surrounding said A/D and including a heat transfer media independent of the refrigerant in the system for exchanging heat with said A/D and the refrigerant in the system.
A method of operating an air conditioning system of the type including a compressor for compressing a refrigerant, a condenser for condensing the refrigerant, an evaporator for evaporating the refrigerant, a discharge fluid line interconnecting the compressor and the condenser, a liquid fluid line interconnecting the condenser and the evaporator, a suction fluid line interconnecting the evaporator and the compressor, and an accumulator/dehydrator A/D disposed in the suction fluid line for accumulating refrigerant, said method comprising the steps of surrounding the A/D with a heat transfer jacket and exchanging heat with the A/D and the refrigerant therein independently of the refrigerant in the system.
