Can You Sleep in the Car with the Heater On in Winter?

It is not advisable to sleep in the car with the heater on in winter. Below is the working process of the car air conditioning system: 1. Compression Process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. 2. Heat Dissipation Process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a significant amount of heat. 3. Throttling Process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply. It is then discharged from the expansion device in a mist form (fine liquid droplets). 4. Heat Absorption Process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During this evaporation process, it absorbs a large amount of heat from the surroundings. The resulting low-temperature, low-pressure refrigerant vapor then re-enters the compressor.
