3P air conditioning, with more than 6 years, rated current 12.9A, outdoor machine wind speed is normal, return air pressure 0.5. Run for tens of minutes, the compressor will overheat protection, wait longer, will reset start. Touch the outdoor machine condenser, feel good hot, running time current 15.5A, what causes this? Is the compressor almost out of order?
Flog a dead horse, the compressor overheating protection short circuit to use, if the compressor end, change again later.If you use it for a while, the compressor doesn't matter. It just proves that the overheating protection element is broken. Congratulations!Typing is not easy, if satisfied, hope to adopt.
Is the air conditioner valve opened small?
First of all, the probability of the press is very small.If it is a fixed frequency machine, there are 1. reasons for lack of fluorine, resulting in excessive exhaust temperature of the compressor and thermal protection. 2., capillary foreign matter partial block, leading to the passage of large, exhaust temperature is too high, appear thermal protection. By current 15.5A, that must be the second case.If it is a frequency converter, the 1. electronic expansion valve opens small, resulting in high exhaust, high power, and thermal protection. 2. is also due to partial occlusion caused by foreign bodies. 3. caused by fluoride deficiency.It is recommended to add the fluoride first and then the throttling device.
