How often do you replace car refrigerants?

Today I will introduce to you the car refrigerant. How often do you change it? As the temperature rises, car air conditioners are slowly beginning to be used by people. Does the air conditioner that have been out of service for a long time still maintain good cooling? The effect? If your air conditioner no longer has a cooling function, then it may be time to change your own refrigerant. The wind blowing on your body after the air conditioner is normally turned on for a period of time will feel very cold and can quickly reach the set temperature. The outdoor compressor can be like electricity. The refrigerator works for a while and stops for a while, which indicates that it is normal. How often should the car refrigerant be changed? Let's take a look with the editor.

How often do the car refrigerants be changed? One, try the air conditioner normally turned on for a period of time, the wind blowing on the body feels very cold and can quickly reach the set temperature The refrigerator works for a while and stops for a while, which shows that it is normal. Otherwise, refrigerant may be needed. 2. Measuring the temperature difference between the inlet and outlet of the indoor unit with a thermometer is above 8°C. The larger the normal temperature difference, the better the working condition of the air conditioner is, and it can reach about 15°C. If the difference is less than 8°C, refrigerant may need to be added. 3. When you turn on the indoor unit panel ten minutes after starting up, you should see that the copper tube of the evaporator is covered with aluminum fins for heat exchange and the parts are evenly covered with condensed water. This is when the normal air humidity is high, and vice versa. If half and half do not, there may be a lack of refrigerant. Such as partial frost or ice formation is also abnormal. 4. Users who have used it for more than half a year can check whether there are obvious signs of oil leakage at the pipe joints of the indoor unit and the valve of the outdoor unit. If there is obvious oil leakage, it indicates that the machine is leaking because of the mutual miscibility of oil and fluorine. The oil leakage will cause fluorine leakage and the fluorine leakage will cause oil leakage.

How often does the automobile refrigerant change: The traditional filling method first discharges the residual refrigerant, then vacuums, and finally refills the meter. With the development of the times and the advancement of technology, people are paying more and more attention to environmental protection. The refrigerant itself is non-toxic and harmless to humans, but it is an important source of pollution to the environment. R12 is the culprit responsible for the global ozone hole. Although its replacement product R134a is not as serious as R12 in the destruction of the ozone layer, it will also pollute the atmosphere.

Automobile refrigerants How often to change: Wrong filling method One wrong operation is to fill directly without vacuuming. Some repair shops will directly discharge the residual refrigerant in the car air conditioner, and then directly fill the refrigerant with the meter group, use the pressure in the refrigerant tank to add the refrigerant to the air conditioning system, and press out the air in the system at the same time. It is very wrong to do it.

The above is how often the car refrigerant introduced by the editor is changed. This is the end of the introduction of the editor. Do you understand the points introduced by the editor above? Cars still need maintenance. I believe that you are more cautious about your car. I hope that the introduction of the editor can help you, and I want to know more about it.
