Why Does the Car Air Conditioner Blow Hot and Cold Intermittently?
1 Answers
The reasons for the car air conditioner blowing hot and cold intermittently include damaged compressor capacitor, dirty filter, and insufficient refrigerant. Introduction to Car Air Conditioning: Car air conditioning 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. 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. Inside 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. The liquid refrigerant flows through the throttle device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs heat from the inside air passing through the evaporator and evaporates, turning into a gas. The gas is then sucked in by the compressor for the next cycle.
