The cooling effect of air-conditioning is poor, what is the problem?

Everyone who drives in the summer cannot do without the air conditioner. If the air conditioner happens to be malfunctioning, driving in the 'oven' is uncomfortable, and it is easy to adversely affect driving safety. Let's take a look at the common reasons why the air conditioner is not cooling, and troubleshoot in time. The cooling effect of air-conditioning is poor. What is the problem?

Condenser impurity accumulation has poor heat dissipation effect

The condenser (also known as the air conditioner radiator) is installed in front of the engine, generally it can be seen by opening the front cover . Dust, silt, mosquitoes, leaves during transportation, catkins, poplar catkins and other impurities that are common in northern spring can easily cover the condenser. After a long time accumulation, the heat dissipation effect will be poor.

Generally speaking, the pipelines and parts of new cars within 2-3 years are not prone to failure. The main reason for the uncooling of the air conditioner is the condenser. The solution to the problem is also very simple. The condenser is relatively not delicate, and most impurities can be cleaned up with an air gun or a water gun when washing the car. The air-conditioning filter element has a poor ventilation effect with dust accumulation. The air-conditioning filter element mainly filters dust and catkins in the air to prevent impurities from entering the air-conditioning system and cause damage, and to ensure good air quality in the car. The long-term operation of the vehicle naturally cannot avoid the accumulation of dust. The main performance conditions are: 1. The air conditioner is noisy, but the air volume is extremely small; 2. The air conditioner has peculiar smell. Generally speaking, it is more appropriate to replace the air-conditioning filter element once every three months. If it is a harsh environment such as a construction site or a mining area, the time should be appropriately advanced.

Damaged pipelines and connecting parts, refrigerant leakage

There are many automotive air-conditioning parts, and the connected hoses and connecting parts have been exposed to high temperature and bumps for a long time. Factors such as aging and loosening are unavoidable, resulting in refrigerant leakage and the air conditioner is not cooling. In addition to replacing and tightening the nuts at the connection in time, we must also isolate the hose from the engine and other components to avoid damage again. Many masters are very experienced, and it is indeed very effective to do a good job of bandaging and fixing the line before the new car is put into operation.

If the compressor and expansion valve are faulty, go to 4S for repair in time

The compressor is comparable to the heart of the air conditioner, which can compress and transmit the refrigerant neatly. Common faults are: 1. Abnormal wear and tear of the internal parts of the compressor, causing obvious noise; 2. The transmission belt slips and does not transmit power. Expansion valve is also called throttle valve, its main function is to create conditions for refrigerant evaporation and control refrigerant flow. At this time, you should go to a professional service point or 4S shop for repairs to avoid greater losses.

Nowadays, air-conditioning has become the standard equipment of almost every car, and our trucks are running on the road day and night, and occasional glitches are inevitable, but as long as we Develop good car use habits, and the probability of sudden breakdowns is relatively low. You should also learn more about your vehicle configuration, and try to find the cause when a malfunction occurs, so as to avoid the cost of unnecessary replacement of parts. Finally, in the hot summer, I hope everyone can use air-conditioning for refrigeration as much as possible. The small amount of fuel saved is not more important than good health.
