1. To look at basic maintenance methods. Carefully observe the performance of air conditioner components, focusing on the refrigeration, electrical and wind systems and determining whether they are working properly. Refrigerator oil may also be used for the purpose of connecting the link with the welding of the pipes with clean sheeting and paper to see if there is any oil contamination to determine whether there is a leak。
2. Hearing of basic methods of air conditioning maintenance. Whether the sound of the air conditioner compressor is functioning properly, with or without abnormal sound, with or without noise, etc. Air conditioners are operating with minor vibrations and less noise under normal conditions, usually below 50db. If the vibrations and noises are too high, there may be reasons such as foam and plastic cushions, which can increase the vibrations and noise of air conditioners while operating. This was particularly evident when it first started and when it stopped. Accusations occur when the chassis is touched, the axes of the fan move and the blades lose balance; if there is an alien in the fan, there is also an impact。
3 the basic method of air conditioning maintenance. The cold, vibrating, etc. Are felt in the relevant parts of the hand-held air conditioner, which helps to determine the nature and location of the malfunction. Under normal conditions, the temperature of the condenser is gradually decreasing from top to bottom, with lower temperatures slightly above ambient temperatures. It is abnormal if the whole condenser is not hot or slightly warm in the upper part, or if the temperature of the two pipes adjacent to the upper and lower is significantly different. The evaporation unit normally places its watered fingers on the evaporation unit's surface, with a chilled feeling of glue. The dryer, the catheter at the export point should under normal conditions have a warmer temperature (which is slightly higher than the ambient temperature and is essentially the same as at the end of the condenser's pipe), such as feeling lower than the ambient temperature or having dew condensing on the surface and temperature differences in the various parts of the catheters. Inhaler tubes at 200mm from compressor should normally have the same temperature as the environment。
Basic methods of air conditioning maintenance. In order to determine precisely the nature and location of the malfunction, the performance parameters and state of the air conditioner are often checked with instruments and instruments. If a leak detector is used to check for refrigerant leakage; if the power source voltage, the power flow to the ground at each end of the line and the running power flow is met by a mass meter, computer-controlled air conditioners should also be measured for the normal level of the control points, etc。
