How Does a Car Air Conditioning Heating System Work?

1 Answers

Car air conditioning systems operate based on the principle of heat release during liquefaction and heat absorption during vaporization, concepts learned in middle school physics. The details are as follows: Heating Principle: The engine drives the compressor via a belt. The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure gaseous state, which is then sent to the condenser (outdoor unit). After dissipating heat, it becomes a liquid refrigerant at normal temperature and high pressure, which is why the outdoor unit blows out hot air. Cooling Principle: The refrigerant passes through the capillary tube and enters the evaporator (indoor unit). As the refrigerant moves from the capillary tube to the evaporator, the space suddenly expands, reducing the pressure. The liquid refrigerant then vaporizes, turning into a low-temperature gaseous refrigerant, absorbing a significant amount of heat in the process. This causes the evaporator to cool down. The indoor unit's fan blows indoor air over the evaporator, resulting in the indoor unit blowing out cold air.
