Daily maintenance of car air conditioners
What are the contents of the daily maintenance of car air conditioners? The following is an introduction.
The daily maintenance of automobile air conditioners mainly focuses on inspection and cleaning and is completed by the owner or driver. The maintenance items, objectives, and requirements.
Daily maintenance of car air conditioners: clean the condenser;
The cleanliness of the condenser has a lot to do with its heat exchange status. Therefore, you should always check the surface of the condenser for dirt and soil. The heat sink is
Whether it is bent or blocked. If the surface of the condenser is found to be dirty, it should be cleaned with compressed air or water in time to keep the condenser in good condition.
Heat dissipation conditions. To prevent the condenser from causing excessively high condensing pressure and temperature and lowering of refrigeration capacity due to poor heat dissipation. In the process of cleaning the condenser
Be careful not to knock down the heat sink, let alone damage the refrigeration piping
Daily maintenance of car air conditioners: check the air inlet filter
The air sent into the cabin must be filtered by the air inlet filter, so it is necessary to check whether the filter is blocked by dust and sundries and imported
The filter is cleaned to ensure sufficient air intake and prevent the air passage of the evaporator core from being blocked and affecting the air supply. -Generally check every week
once
Daily maintenance of automobile air conditioners: check the compressor transmission belt
Regularly check the use and tightness of the transmission belt of the refrigeration compressor. If the transmission belt is loose, it should be tensioned in time. If a crack is found in the transmission belt, check
Compression or damage should be replaced with a special transmission belt for automobile air conditioners. In addition, the newly installed air-conditioning transmission belt will stretch after 36~48 hours of use.
The drive belt of the machine should be re-tensioned, the tension is generally 441~490N
Daily maintenance of car air conditioners: regularly start the air conditioner compressor
In the spring and autumn or winter seasons when the air conditioner is not used, the air conditioner compressor should be started every half a month, 5~10min each time. In this way, the refrigerant is circulating
It can bring the refrigerated oil to all parts of the system, so as to prevent the sealing rubber ring in the system pipeline, the compressor oil seal, etc. from being caused by oil shortage and drying.
Poor sealing and refrigerant leakage, and prevent the action of the compressor, expansion valve, and the moving parts in the system from sticking, sticking, or rusting. Also, note
The point is that this operation should be carried out when the ambient temperature is higher than 4°C, otherwise. When the ambient temperature is too low, the viscosity of the refrigerating oil will be too high
The fluidity of the ambassador deteriorates, and when the compressor is started, the oil cannot be brought to the parts that need lubrication immediately, causing the compressor to wear and even damage.
Daily maintenance of automobile air conditioners: observe the refrigerant reserves
Regularly observe whether there is a lack of refrigerant through the sight glass installed on the top of the liquid storage waist dryer or on the high-pressure pipeline behind the cold quilt.
Daily maintenance of car air conditioners: check the connection of each component
Frequently check whether the pipe joints and connecting parts, bolts and screws of the refrigeration system are loose, and whether there is any friction and collision with surrounding parts.
Like, whether the rubber hose is aging, whether the vibration isolation limb pads at the entrance and exit of the fender hole are off or damaged
Daily maintenance of car air conditioners: pay attention to the abnormal conditions of the air conditioner
During the operation of the air conditioner, attention should be paid to whether there are abnormal noises, abnormal noises, vibrations, and abnormal odors. If there are any, stop using it immediately and send it to a professional repair department for timely inspection and repair.
