Outside the air conditioner, the fine copper tube, the cool thick copper tube, the normal temperature indoor air is not cold, has the compressor broken?
Whether it can operate properly, if it can operate normally, but not refrigeration, is refrigerant leak, need to add refrigerant.
Crude pipe temperature, that is, no refrigerationYou have to look at the compressor outside the machine has not run, you can see if there is no vibration, you know there is no running, as well as the external fan also have to turn,If there is operation, usually refrigerant leakIf not running,You want to see if you hit 16 degrees after the boot, and if it's running (half a minute or a short time), or it's not running at allIf there is a run, and then stopped, generally protected, such as the outer fan did not turn, other high temperature and so onIf nothing is done, the more common fault is that the boot capacitor is broken, or the control circuit is bad, or the compressor itself is bad
This should not concern the compressor! When the compressor starts, there's usually nothing wrong with it! Is the refrigerant enough? And the voltage in your house is not enough!
This is obviously a lack of refrigerant, cold pipe, indicating that the compressor is at work.First of all, to ensure that indoor and outdoor cleaning, ventilation smooth, but also to ensure that the normal work of air-conditioning basic conditions, including indoor filter screen, outdoor fins clean. Recommend cleaning at least 2 times a year, according to the use of it!In fact, air conditioning refrigeration is not good or not refrigeration, not necessarily is the lack of refrigerant, in the air quality is no problem, installed in place, the air-conditioning used more than the design life will not be lack of refrigerant.As a non professional, how to simply determine whether the air conditioning is lack of refrigerant, then observe and touch the outdoor machine, high and low pressure valve, frost situation and temperature bar.1, under normal circumstances, high pressure valve drying, and there is a certain Yu Wen (long working in refrigeration, there will be a small amount of condensate), low pressure valve moist and water dew, water dew according to the weather conditions.2, high pressure valve drying (long working in the refrigeration state, there will be a small amount of condensate), low pressure valve frosting, which is the lack of refrigerant.3, high pressure valve frosting, low pressure valve is frosted or dry, that is serious lack of refrigerant or system micro plug.4, high pressure valve drying is not cool, low pressure valve drying is not cool, the system is seriously leaking, or compressor does not work.
