Motor vehicle air conditioning system controlling method, involves allowing cold accumulator to be cooled by evaporator, where evaporation temperature is reduced in time interval before stopping coolant circuit

摘要

The method involves allowing a cold accumulator (20) to be cooled by an evaporator (16), where an evaporation temperature of a coolant in the evaporator is adjusted depending on a requirement within a temperature range. The evaporation temperature of the coolant in the evaporator is reduced in a time interval before stopping a coolant circuit (10), where the time interval is determined before stopping the coolant circuit by using a detection device (32) or a navigation system.
