WIPO Patent Application WO/2024/092919
Kind Code:
A1
Abstract:
Provided in the present invention is a thin and lightweight air-conditioning unit. The thin and lightweight air-conditioning unit comprises a compressor, a condenser, an electronic expansion valve and an evaporator, which are sequentially connected to each other to form a refrigeration cycle loop. A condensation fan for exchanging heat with the outdoors is arranged on the condenser, and a blower for supplying air to the indoors is arranged on the evaporator. A microchannel heat exchanger is used inside the condenser, and the compressor is a variable-frequency compressor. In the thin and lightweight air-conditioning unit provided in the present invention, since the interior of the condenser is designed to be provided with the microchannel heat exchanger, the spatial size of the condenser is more compact and thus space is saved, such that the lightweight design can be further achieved on the basis of satisfying the refrigeration and heating requirements of a vehicle.
