A device and a method are provided for heating and cooling a compartment of a motor vehicle powered by an internal combustion engine. The device has a coolant circuit with a compressor, an ambient heat exchanger, at least one expansion device, an interior heat exchanger, and an exhaust heat exchange
A device and a method are provided for heating and cooling a compartment of a motor vehicle powered by an internal combustion engine. The device has a coolant circuit with a compressor, an ambient heat exchanger, at least one expansion device, an interior heat exchanger, and an exhaust heat exchanger that can be heated by exhaust gases from the engine. During heating, a coolant is guided through the compressor and through the interior heat exchanger connected downstream from the compressor, releasing heat. The compressor, interior heat exchanger, expansion device, ambient heat exchanger, and heat exchanger are connected in series so that the coolant is expanded in the expansion device to a temperature below an intake temperature of coolant into the compressor, exposed in the ambient heat exchanger to warmer ambient air, heated in the heat exchanger by the exhaust gases from the engine, and compressed in the compressor. During cooling, the compressor, ambient heat exchanger, expansion device, and interior heat exchanger are connected in series, with the coolant being exposed to cooler ambient air in the ambient heat exchanger and expanded in the expansion device to a temperature below a compartment air temperature. The compartment air is exposed in the interior heat exchanger to the cooler coolant.
