The air conditioner is not cool cool thin copper thick pipe room is going on is not cold air compressor bad again
This is obviously a lack of refrigerantFirst 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.
Not compressor. It is refrigerant. It may be pipe leak. Please find professional maintenanceUnder normal working conditions, the thin pipe has water dew and the thick pipe will frostingAskPlus snow, maintenance personnel said, "do not go in, blocked for a while," said the compressor is broken, I am afraid they black meChasing the answerWell, in fact, there is no need to repair, and buy a new, but also to change the point. Repair, at least 300-400 or so. And then add a little money, may buy a new
Since the thin copper cooler, indicating that the compressor is not bad; adjust the expansion valve to try, now the summer pressure difference to 15 degrees, if not, it is not filled with refrigerant. How to check the pressure, whether in the normal range.
