Abstract
In a vehicle air conditioning system, a cold accumulator is disposed between a downstream air side of a cooling heat exchanger and an upstream air side of a heating heat exchanger to be cooled by cold air having passed through the cooling heat exchanger. Further, the cold accumulator is disposed at the upstream air side of an air mixing door.
Claims30
An air conditioning system for a vehicle having a passenger compartment, the system comprising:
- a case defining an air passage through which air flows into the passenger compartment;
- a cooling heat exchanger in which refrigerant of a refrigerant cycle flows, the cooling heat exchanger being disposed in the air passage;
- a heating heat exchanger disposed at a downstream side of the cooling heat exchanger in an air flow direction;
- an air mixing door disposed to adjust a flow amount ratio between air passing through the heating heat exchanger and air bypassing the heating heat exchanger;
- and
- a cold accumulator disposed in the case between the cooling heat exchanger and the air mixing door, the cold accumulator having a cold accumulating material that is sealed only within the cold accumulator.
