Abstract
A cold energy storage system for a vehicle includes an air-conditioning unit that includes an evaporator and a heater core. The system stores cold energy during a cooling operation and supplements the cooling operation by using the stored cold energy after stoppage of the cooling operation. A cold energy storage tank () connects in parallel to an engine cooling circulation circuit to the heater core. The storage tank () has a liquid storage layer (A) for engine coolant and a refrigerant layer (B) in which refrigerant from the evaporator flows. A mode switcher switches between a storing cold energy mode and a cooling supplement mode. In the storing cold energy mode, engine coolant stored in the liquid storage layer (A) is refrigerated during the cooling operation. In the cooling supplement mode, refrigerated engine coolant from the liquid storage layer (A) is introduced to the heater core.
