Abstract
A method for operating an air-conditioning system of a motor vehicle, wherein the air-conditioning system comprises a refrigerant circulation and a water circulation which are thermally coupled with one another across a condenser/gas cooler. Water circulation flows through the condenser/gas cooler at a low volumetric rate of flow and a high temperature difference so the water circulation transfers heat in the heating heat exchanger to the air in a similar temperature range. Refrigerant circulation cools from 65° C. to 70° C. to −10° C. to +30° C. and water circulation raises to a temperature of 55° C. to 65° C. and that an adaptation of the temperature profile of the water circulation to the temperature profile of the refrigerant circulation takes place in the condenser/gas cooler utilizing a temperature glide of the refrigerant. The refrigerant is significantly cooled.
