Abstract:
A device for heating and cooling a compartment of a motor vehicle powered by an internal combustion engine comprising a circuit with a compressor, an ambient heat exchanger, a throttle device, an interior heat exchanger, and an exhaust heat exchanger which is to be heated by exhaust from the engine,wherein, during a heating operation, the compressor, the interior heat exchanger, the throttle device, the ambient heat exchanger, and the exhaust heat exchanger are connected in series so that a medium in the circuit can be expanded in said throttle device to a temperature below an intake temperature of the medium in the compressor, exposed to ambient air in said ambient heat exchanger, heated in said exhaust heat exchanger by the exhaust from the engine, and compressed in the compressor, wherein, during a cooling operation, the compressor, the ambient heat exchanger, the throttle device, and the interior heat exchanger are arranged in series, with the medium in the circuit being exposed to ambient air in said ambient heat exchanger and being expanded in said throttle device to a temperature below a compartment air temperature, and wherein the compartment air is exposed to the medium in the circuit in said interior heat exchanger.
