The pointer of the high pressure meter of automobile air conditioner swings greatly.DivinefortunemegawaysIt is one of the problems that car owners often encounter. From a professional point of view, this article will analyze several possible reasons behind this phenomenon and help you better understand and deal with this problem.
oneDivinefortunemegaways. The refrigerant charge is not accurate
The inaccurate refrigerant charge is one of the common reasons for the large swing of the pointer of the high voltage meter. If the refrigerant charge is too much, the internal pressure of the system will be too high, which will make the pointer of the high pressure meter swing greatly. On the contrary, if the refrigerant charge is too small, the system pressure will be too low, which will also lead to the large swing of the high pressure meter pointer. Therefore, it is very important to maintain the accuracy of refrigerant charge.
The problems that may be caused by the refrigerant charge are too much charge, too much high pressure in the system, too little in the system, too much pointer swing in the high voltage meter, and too low pressure in the system.two。 Blockage of refrigeration system
The blockage of the refrigeration system is also an important reason for the large swing of the pointer of the high-voltage meter. If the high-pressure side or the low-pressure side of the refrigeration system is blocked, the refrigerant can not flow smoothly, which leads to the abnormal fluctuation of the system pressure and makes the pointer of the high-pressure meter swing greatly.
The blocking position may lead to the problem that the blocking refrigerant on the high pressure side can not flow smoothly, the system pressure is too high and low pressure side blocking refrigerant can not flow smoothly, and the system pressure is too low.3. Abnormal operation of air conditioning compressor
The air conditioning compressor is the core component of the refrigeration system. If the compressor works abnormally, it will also cause the pointer of the high pressure meter to swing greatly. The abnormal operation of the compressor may be caused by the fault of the compressor itself or the failure of the compressor electromagnetic clutch.
Problems caused by faulty components the compressor itself does not work properly, affecting the operation of the refrigeration system, the compressor electromagnetic clutch compressor can not work properly, affecting the operation of the refrigeration systemIt is strongly recommended that car owners maintain the automobile air-conditioning system regularly in order to avoid the above problems. If the pointer of your car air-conditioning high-pressure meter swings greatly, it is recommended to contact professional maintenance personnel for inspection and maintenance as soon as possible to ensure the normal operation of the car air-conditioning system.
