Cleaning method of automobile condenser.
The "automobile condenser" is an important part of the automobile air conditioning system, which is mainly responsible for releasing the refrigerant heat in the high-pressure state of the compressor into the air to achieve the refrigeration effect. Because the condenser is exposed, it is easy to accumulate dust, catkins, insects and other debris, which affects the heat dissipation effect, and then affects the cooling performance of the air conditioning system. Therefore, regular cleaning of the condenser is an important measure to maintain a good cooling effect of air conditioning.
The steps of condenser cleaning usually include:
Prepare cleaning tools and materials. This may include cleaning agents, water pipes, spray guns, etc.
Start the car and turn on the air conditioning so that the electronic fan starts spinning. This step helps to better distribute the cleaning solution during the cleaning process.
The condenser is initially flushed with clean water, and the rotation of the fan helps the water spread across the surface of the condenser.
If there is much dirt on the surface of the condenser, special washing products can be used and sprayed on the surface of the condenser after adding water according to the instructions. During the spraying process, the electronic fan should be kept running to help draw in and distribute the cleaning agent to all corners of the condenser.
After cleaning, rinse the condenser with plenty of water to ensure that all cleaning agents are completely removed. This step is critical because residual cleaning agent may affect the cooling performance of the condenser.
Finally, check whether the condenser is clean and rinse again if necessary until no cleaning agent remains.
Note:
In the cleaning process, it should be noted that the water pressure should not be too high, so as not to damage the heat sink of the condenser.
Avoid using excessive pressure water gun or high pressure cleaning equipment to avoid damaging the heat sink of the condenser.
If conditions permit, you can use the air gun to blow away the large particles of dust and debris on the surface of the condenser, and then clean it.
When using the cleaning agent, it should be diluted according to the instructions to avoid using too high concentration to prevent corrosion of the condenser material.
Through the above steps and precautions, the owner can effectively clean the condenser at home, thereby maintaining the best performance of the air conditioning system.
What is the type of car air conditioner condenser
The condenser is a part of the refrigeration system, which belongs to a heat exchanger, which can convert the gas or vapor into a liquid and transfer the heat of the refrigerant in the tube to the air near the tube. (Evaporators in car air conditioners are also heat exchangers)
The role of condenser:
The high temperature and high pressure gaseous refrigerant discharged from the compressor is cooled and condensed into liquid refrigerant at medium temperature and high pressure. Note: The refrigerant entering the condenser is almost 100% gaseous, but it is not 100% liquid when it leaves the condenser. Because only a certain amount of heat can be discharged by the condenser in a given time, a small amount of refrigerant will leave the condenser in the form of gas, but because these refrigerants will enter the liquid storage dryer, this phenomenon does not affect the operation of the system.

Heat release process of refrigerant in condenser:
There are three stages: superheating, condensation, and supercooling
1. The refrigerant entering the condenser is a high-pressure superheated gas, which is first cooled to the saturation temperature under the condensing pressure, at which time the refrigerant is still a gas.
2. Then under the action of condensing pressure, heat is released and gradually condensed into liquid, and the temperature of the refrigerant remains unchanged during this process. (Note: Why does the temperature not change? This is similar to the process of solid to liquid, solid to liquid need to absorb heat, but the temperature does not rise, because the heat absorbed by the solid is all used to break the binding energy between the solid molecules. In the same way, when a gas becomes a liquid, it needs to give off heat and reduce the potential energy between molecules.)

3. Finally, continue to release heat, the liquid refrigerant temperature drops, becoming a supercooled liquid.
