8. An air conditioning system for a motor vehicle, the air conditioning system comprising:
- a compressor located along a flow path;
a condenser located along the flow path downstream from the compressor, the condenser including a plurality of heat exchange tubes in fluid connection with the flow path;
an expansion device located along the flow path downstream from the condenser, the expansion device including an orifice configured to regulate a fluid flow along the flow path;
an accumulator located along the flow path downstream from the expansion device, the accumulator including an accumulator housing defining an accumulator chamber;

Abstract
An accumulator for the air conditioning system of a motor vehicle. The accumulator includes a housing defining an accumulator chamber for receiving a fluid and permitting the fluid to separate into a gas state portion and a liquid state portion. A conduit, which defines a passageway for carrying fluid along a flowpath, extends through the housing and across the accumulator chamber such as to permit heat transfer between the accumulator chamber and the passageway. When utilized in the air conditioning system, the accumulator is preferably located upstream of the evaporator.

15. An air conditioning system for a motor vehicle, the air conditioning system comprising:
-
a compressor for generating a pressure increase in a flow of a fluid;
a condenser configured to receive the fluid from the compressor and to permit the fluid to undergo heat exchange;
an expansion device configured to receive the fluid from the condenser and to regulate a flow rate of the fluid flowing the expansion device;
an accumulator having a housing defining an accumulator chamber, wherein the accumulator is configured to receive the fluid from the expansion device, the fluid in the accumulator chamber including a liquid phase portion and a gas phase portion;
an evaporator configured to receive the liquid phase of the fluid from the accumulator chamber and to permit the liquid phase of the fluid to undergo heat exchange; and
a conduit configured to deliver the fluid from the evaporator to the compressor, the conduit extending across the accumulator chamber and defining a passageway therein between first and second ports, the conduit configured to permit heat transfer between accumulator chamber and the passageway defined by the. conduit. - View Dependent Claims (16, 17, 18, 19, 20)
