Vehicle air conditioning system with cold accumulator
First Claim
1. 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, disposed in the air passage, for cooling air;
a heating heat exchanger, disposed at a downstream side of the cooling heat exchanger in an air flow direction, for heating air;
an air mixing door which is 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 which is disposed between a downstream side of the cooling heat exchanger and an upstream side of the air mixing door in the air flow direction to be cooled by cold air after passing through the cooling heat exchanger.

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 an air mixing door, to be cooled by cold air having passed through the cooling heat exchanger. Therefore, the cold accumulator can be readily cooled by the cold air from the cooling heat exchanger, while having a simple structure. Further, the cold accumulator is disposed at the upstream air side of the air mixing door, the cold accumulator can be effectively cooled without being affected by a rotation position of the air mixing door.

31. An air conditioning system for a vehicle having a passenger compartment, the system comprising:
-
a cooling heat exchanger disposed for cooling air to be blown into the passenger compartment;
a cold accumulator disposed at a downstream air side of the cooling heat exchanger to be cooled by cold air after passing through the cooling heat exchanger; and
a control unit for controlling temperature of air to be blown into the passenger compartment, wherein;
the control unit controls temperature of the cooling heat exchanger to a target cooling temperature;
in a cold accumulation mode for performing a cold accumulation in the cold accumulator, the control unit sets the target cooling temperature at an initial target temperature; and
when the control unit determines a finish of the cold accumulation in the cold accumulator, the control unit sets the target cooling temperature to be switched from the initial target temperature to a predetermined temperature that is higher than the initial target temperature. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
