The car air conditioner has been used for a long time, and the condenser will have dust, catkins, leaves and small insects attached to it, which will cause poor heat dissipation and increase the engine temperature; the condenser is the external circulation part of the air conditioner and is used to transfer the heat absorbed in the car If the temperature is too high, it will cause the pressure in the system to rise. When the pressure reaches a certain level, the air conditioner will self-protect and shut down, and the compressor will not work; this is what we often call over-pressure protection (also called high-pressure protection) , So it is necessary to clean the condenser.
Therefore, the car air conditioner needs to be cleaned at least once a year; according to professionals, if the car air conditioner is not cleaned for a long time, it will accumulate a lot of dust, which will cause secondary air pollution, which will affect the health of the user after inhalation. Clean it once a month; the cleaning cycle of the filter can be adjusted appropriately according to the frequency of use and the environment.
Car condenser cleaning method1. Mix the detergent with water. The washing product of the condensing net is alkaline, which is slightly corrosive to the condenser, so it is important to add water to reduce the concentration, because too high concentration will only wash cleanly, but the corrosiveness must be considered.
2. Start the car, turn on the air conditioner, and make the electronic fan rotate. First rinse with clean water, and use the rotation of the fan to spread the clean water throughout the condenser. It must be flushed thoroughly. During this period, the electronic fan may stop because the condenser temperature is too low. At this time, stop flushing and let the condenser The temperature rises, causing the electronic fan to run again.
3. After the entire condenser is soaked, use a water spray tool (such as watering flowers, etc.) to spray the mixed washing product onto the surface of the condenser. At this time, the electronic fan should also be running and use it The movement is sucked in and distributed to all corners, and it is estimated that all the sprays are enough. At this time, turn off the air conditioner and engine and observe the surface of the condenser. After a few minutes, you will see that the dirt on the surface will slowly "float" with some small bubbles. Wait a few minutes (we usually wait ten to Fifteen minutes, depending on the concentration).
4. Start the air conditioner again to rotate the fan. At this time, rinse with a lot of water. The more thorough the rinse, the better. Don’t be lazy at this step. When you’re done, you will find that the surface of the condenser is clean. We generally can. Wash the condenser until it looks like new.
