Title:
AIR-CONDITIONING APPARATUS FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2017/014030
Kind Code:
A1
Abstract:
In the present invention, if rapid cooling is unnecessary (No in S2), an air-conditioning ECU 40 sets the target compression ratio of a compressor 23 (S4), and calculates a compression ratio (S5). If the compression ratio is higher than the target compression ratio (Yes in S6), the air-conditioning ECU 40 implements compression reduction control (S7) to increase the opening of an expansion valve 26, increase the output of an evaporator fan 20, and/or increase the output of a condenser fan.
