Method for controlling the power consumption of the compressor of a vehicle air-conditioning circuit, and related system

摘要

The method involves simultaneous checking of temperature of air blown by an evaporator and of a difference in temperature on a surface of the evaporator. An expansion rate of a relaxation element (9) is reduced as long as the temperature of the air blown by the evaporator is lower or equal to 15 degrees Celsius and the difference in temperature on the surface of the evaporator is lower than 5 Kelvin. A cubic capacity of a mechanical type compressor or number of revolutions of an electric type compressor is reduced. An independent claim is also included for a control system.
