As a high-speed rotating working part, the air conditioner compressor has a relatively high probability of failure. Common faults include abnormal noise, leakage, and non-working.
Refrigerant leakage is the most common problem in air conditioning systems. The leakage of the compressor is usually at the junction of the compressor and the high and low pressure pipes, where it is usually troublesome to check because of the installation position. The internal pressure of the air-conditioning system is very high. When the refrigerant leaks, the compressor lubricating oil will be lost, which will cause the air-conditioning system to not work or poor lubrication of the compressor. There are pressure relief protection valves on the air conditioner compressors. The pressure relief protection valves are usually for one-time use. After the system pressure is too high for pressure relief, the pressure relief protection valve should be replaced in time.
(2) Abnormal sound
There are many reasons for the abnormal noise of the compressor. For example, the electromagnetic clutch of the compressor is damaged, or the internal wear of the compressor is severely worn, etc., which can cause abnormal noise.
①Compressor electromagnetic clutch is a common part of abnormal noise. The compressor often runs from low speed to high speed under high load, so the electromagnetic clutch is very demanding, and the installation position of the electromagnetic clutch is generally close to the ground, and it is often exposed to rain and soil. When the bearing in the electromagnetic clutch is damaged There will be abnormal noise.
② In addition to the problem of the electromagnetic clutch itself, the tightness of the compressor transmission belt also directly affects the life of the electromagnetic clutch. If the transmission belt is too loose, the electromagnetic clutch will easily slip; if the transmission belt is too tight, the load on the electromagnetic clutch will increase. Improper tightness of the transmission belt may cause the compressor to not work at a slight degree, and may cause damage to the compressor. When the transmission belt is working, if the compressor pulley and the generator pulley are not in the same plane, the service life of the transmission belt or the compressor will be reduced.
③There should be a certain gap between the electromagnetic clutch and the compressor mounting surface. If the gap is too large, the impact will increase. If the gap is too small, the electromagnetic clutch will interfere with the compressor mounting surface when it works. This is also a common cause of abnormal noise.
④ Repeated engagement of the electromagnetic clutch will also cause abnormal noise in the compressor. For example, the power generation of the generator is insufficient, the pressure of the air conditioning system is too high, or the engine load is too large, which will cause the electromagnetic clutch to repeatedly engage.
⑤ Reliable lubrication is required when the compressor is working. When the compressor lacks lubricating oil, or the lubricating oil is used improperly, serious abnormal noise will be produced inside the compressor, and even wear and tear of the compressor will be caused.
(3) Not working
There are many reasons why the air conditioner compressor does not work, usually because of related circuit problems. You can preliminarily check whether the compressor is damaged by directly supplying power to the electromagnetic clutch of the compressor.
Precautions for air conditioning maintenance:
Safety issues that should be paid attention to when handling refrigerants:
(1) Must wear protective glasses;
(2) Do not handle refrigerant in a confined space or near an open flame;
(3) Do not face the bottom of the refrigerant tank to people, some refrigerant tanks have emergency venting devices;
(4) Avoid liquid refrigerants entering the eyes or splashing on the skin;
(5) Do not put the refrigerant tank directly in hot water with a temperature higher than 40°C;
(6) If the liquid refrigerant enters the eyes or touches the skin, do not rub it, rinse it with plenty of cold water immediately, go to the hospital for professional treatment immediately, and do not try to handle it yourself.
