Abstract
A method and a device for heating and cooling a compartment of a motor vehicle powered by an internal combustion engine are described. During a cooling operation, a medium in the circuit is guided through a compressor, an ambient heat exchanger, a throttle device, and an interior heat exchanger which are connected in series and form an integral closed circuit. On the high-pressure side of the circuit, a supercritical pressure is produced at the same time that a subcritical pressure is produced on the low-pressure side of the circuit. During a heating operation, the high-pressure side of the circuit during the cooling operation becomes the low-pressure side and the low-pressure side of the circuit during the cooling operation becomes the high-pressure side. The medium in the circuit is conducted in the interior heat exchanger at a supercritical pressure, with heat energy being transferred from the medium in the circuit to the compartment air supplied to the compartment. The medium in the circuit is additionally guided through an exhaust heat exchanger.
