Abstract

An air-conditioning system is designed at least for an air-conditioning mode for cooling a thermal control medium (13) and a heat-pump mode for heating the thermal control medium. The system comprises a refrigerant circuit with a compressor (1) and an evaporator (8), a coolant circuit with a heat-generating unit (10) to be cooled and a heater (12) for heating the thermal control medium, and also a first refrigerant/coolant heat exchanger (3) functioning on the refrigerant side as a condenser/gas cooler. The evaporator is formed by a second refrigerant/coolant heat exchanger (8). A cooling body (14) for cooling the thermal control medium is connected downstream of heat exchanger (8) on the coolant side.
