Why is the car air conditioner emitting cold air?
2 Answers
It is normal for a car air conditioner to emit cold air. Since the indoor air is relatively humid, when the low-temperature cold air blown out by the air conditioner meets the humid air, it becomes atomized, forming mist, which looks like white smoke. If the outside air is very humid, it is easy for the air vent to emit a white gas without any noticeable cooling effect. Relevant information about car air conditioners is as follows: 1. Introduction: The car air conditioning device (air-conditioning-device), referred to as car air conditioning. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car compartment to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device.
I've been driving for over twenty years and have a lot of experience with car air conditioning. The cold air coming from the car AC is actually the result of its normal working principle: the compressor compresses the refrigerant into a high-pressure gas, which then dissipates heat through the condenser and turns into a liquid. It then enters the evaporator, expands, and absorbs heat. At this point, the fan blows the hot air inside the car over the surface of the evaporator, lowering the temperature, and cold air comes out of the vents. However, attention must be paid to details, such as whether the refrigerant is sufficient and whether there are any leaks in the pipes. If the refrigerant leaks, the cold air will become weaker or not cold at all. The compressor is driven by the engine, and its effectiveness is reduced when the engine speed is insufficient. Problems are more likely to occur during the high temperatures of summer. I often remind my friends to regularly replace the AC filter to avoid dust clogging and affecting ventilation. If cold air comes out but there is a hissing sound or an unpleasant odor, it's time to check for aging seals or bacterial growth. Timely cleaning can avoid expensive repairs.
