摘要 |
The present invention concerns a method for cooling a passenger compartment in a hybrid vehicle that operates an engine intermittently during vehicle operation, the hybrid vehicle having an HVAC system including an HVAC duct, a blower adapted to direct a flow of air through the HVAC duct, and an evaporator located within the HVAC duct. The method includes the steps of operating the blower; operating the compressor; allowing a predetermined amount of ice to form on the evaporator during operation of the compressor; turning off the vehicle engine; ceasing operation of the compressor; measuring an indicator corresponding to a remaining amount of the predetermined amount of ice formed on the evaporator; and re-starting the compressor when a predetermined air temp in air duct is reached.
