What are the symptoms of a clogged car air conditioner?

There may be an increase in engine temperature. The following is a related introduction to car air conditioners: 1. Introduction to car air conditioners: A car air conditioner is an air conditioning system composed of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, used to regulate the temperature and humidity inside the car and provide a comfortable environment for the driver. 2. Working principle: When the compressor is working, it sucks in low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. In the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid. When the liquid refrigerant flows through the throttle device, its temperature and pressure decrease, and it enters the evaporator. In the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs heat from the air inside the car passing through the evaporator and evaporates, turning into a gas. The gas is then sucked into the compressor for the next cycle.
