Claims
- 1. 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.
- 2. The device according to claim 1, and further comprising a bypass line provided between said throttle device and said exhaust heat exchanger permitting the medium in the circuit to bypass said ambient heat exchanger and be guided directly into said exhaust heat exchanger.
- 3. The device according to claim 1, wherein said exhaust heat exchanger is a countercurrent heat exchanger.
- 4. The device according to claim 1, wherein the throttle device is an expansion valve.
- 5. The device according to claim 1, and further comprising a collecting container to receive the medium in the circuit provided on the intake side of the compressor.
- 6. The device according to claim 1, wherein said compressor has an adjusting device for adjusting the compression stroke.
