Title:
VEHICLE AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/039615
Kind Code:
A1
Abstract:
The present invention addresses the problem of reducing a fill amount of a heat medium to be sealed within a refrigeration cycle circuit in a vehicle air conditioning device. The device comprises: a compressor that compresses the heat medium; a condensing heat exchanger that condenses the compressed high-pressure heat medium; an expansion valve that expands the condensed heat medium; and an evaporating heat exchanger that evaporates the expanded low-pressure heat medium. Among the refrigeration cycle circuit that circulates the heat medium so as to pass through the compressor, the condensing heat exchanger, the expansion valve, and the evaporating heat exchanger in that order, a flow channel from the condensing heat exchanger to the expansion valve is shorter in length or smaller in volume than a flow channel from the expansion valve to the evaporating heat exchanger.
