<p>The invention relates to an air-conditioning system for a motor vehicle comprising an integrated heat pump for cooling and heating, in which coolant is circulated and which enables a heat exchange with the passenger compartment supply air of the motor vehicle. The heat transfer ensues either directly by means of a coolant-air heat exchanger through which passenger compartment supply air can flow or by means of a secondary coolant circuit. Two expansion devices and three heat exchangers are provided in the coolant circuit of the heat pump.</p> |
