Title:
AIR-CONDITIONING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/024665
Kind Code:
A1
Abstract:
This air-conditioning control device (50) is used in a vehicle provided with an air-conditioning system which comprises a refrigerant passage (25), an electric compressor (22), an evaporator (21), and a blower fan (12), and which is capable of blowing cool air cooled by the evaporator into a cabin by driving the blower fan. If the vehicle has been left unattended and the cabin interior is in a high temperature state, the air-conditioning control device performs scavenging on the cabin interior as pre-air conditioning before a user boards the vehicle and, after the completion of the scavenging, performs cooling air-conditioning. The air-conditioning control device in the vehicle in a high temperature state drives the blower fan in response to a pre-air conditioning request in order to scavenge the cabin interior, determines whether or not a user has boarded the vehicle during the scavenging, and if it is determined that a user has boarded, performs scavenging such that the air blown into the cabin by the blower fan is limited to the reduction side compared to before the determination that the user had boarded, and starts driving the compressor in order to start cooling air conditioning inside the cabin.
