VEHICULAR AIR-CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/241612
Kind Code:
A1
Abstract:
[Problem] To promote ducting of heat from an air-conditioning heat transfer medium during cooling, to improve operating efficiency. [Solution] The present invention includes: a heat exchanger 13 that carries out heat exchange between outside air passing through the environs and an air-conditioning heat transfer medium passing through the interior; and a heat exchanger 43 that carries out heat exchange between an air-conditioning heat transfer medium and a cooling heat transfer medium that separately pass through the interior. During cooling, the air-conditioning heat transfer medium is circulated so at to go by way of, sequentially, an expansion valve 37, an evaporator 15, a compressor 35, a condenser 16, the heat exchanger 43, and the heat exchanger 13. Meanwhile, the cooling heat transfer medium is circulated so at to go by way of, sequentially, the heat exchanger 43 and a radiator 42.
