Gree air-conditioning cooling effect is not a small one a small one, Gree air-conditioning cooling effect is not good, I could not find the reason, not lack of freon, fan is running, drainage normal, normal operation of the compressor. The machine is also cleaned, the outlet temperature of 20 degrees, how to adjust the remote control or the outlet temperature of 20 degrees, the other can not find the problem in the air conditioning repair special attention to the temperature and humidity. Do you want these days the country is almost everywhere a year and stuffy inside the hottest days of air conditioning, air conditioning usage normally not so high, but now almost no one will feel bad money without a few open air, so since Very few places in the power supply will be so good, especially the second and third areas would be not to talk about it. Large air-conditioned room is small so it is almost everywhere, while the former may also be a little better these days certainly does not. Think about it; air conditioning cooling heat greater than room temperature will drop, until the heat absorption refrigeration equal amount of time, the room temperature will not fall, if the heat absorbed is greater than the cooling capacity, then the cooling effect is obviously not as good as over. ..... air conditioning does not boot method of repair air conditioning is not turned on, do not start there are two kinds, the first is the power no response, [transformers, fuse, rectifier bridge] these things should be a pediatrician, an important measure 5V voltage and other such problems are normal in most of the CPU for Crystal [next] can be resolved. There is also a plug-in buzzer sound, remote control can not boot [manual] basically is the first to receive bad LF receiver will not know, under the online search to find receiver board foot is easy, right, negative capacitance or board very wide that line, find other legs and feet easily decline oh] Cooling air conditioning installed idea for several reasons, the process did not tighten the screw mouth, causing refrigerant leakage. As long as this problem tighten the screws, and then make up the refrigerant line. Air conditioning dirty. If the air conditioner is dirty it will result in heat well inside and outside. Like this relatively easy to solve. As long as clean air will solve the problem. Air conditioning refrigerant shortage, will also affect the air conditioning and refrigeration. Since the cooling system leak participate within the system thermal cycling refrigerant (refrigerant) insufficient, resulting in decreased efficiency of heat exchange, resulting in insufficient cooling capacity phenomenon. This Just fill plus snow on it. After long-term use of air conditioning air conditioning repair phone Xuzhou, Xuzhou aging Hisense air conditioning compressor sales calls, power increases Xuzhou air conditioning repair parts, energy efficiency decreases, resulting in performance degradation, such problems have no good way, only the air-conditioning system processing, change the air filter, replace the compressor oil. (Note: different grades, grade compressor oil Do not mix). If not, you can only replace the compressor or buy a new air-conditioning. Xuzhou cleaning and maintenance, Sheng Erda refrigeration, air-conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
