THERMAL STORAGE UNIT AND VEHICLE AIR CONDITIONER

摘要

A thermal storage unit includes a thermal storage, a heat exchange path, a housing and a reservoir. The thermal storage is filled with a thermal storage medium. A heat exchange medium flows through the heat exchange path. The housing surrounds and thermally insulates the thermal storage from the outside. The housing has an inlet port and an outlet port for communicating with the heat exchange path and a conduit which is located outside the housing and connected to the inlet port and the outlet port. The reservoir is located in the housing for reserving the heat exchange medium. When the thermal storage unit is not in use, the reservoir collects the heat exchange medium flowing by weight thereof through the inlet port and the outlet port, thereby allowing air to be present at the inlet port and the outlet port.
