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 almost everywhere inside the country and stuffy hottest days of the year, normally air conditioning usage is not so high, but now almost no one will feel bad money without a few open air, so air conditioning since Xuzhou repair parts, almost no power in several places 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 is not cooling because suddenly? Air conditioning suddenly not cooling may have the following reasons: First, compressor thermal protection. (Just machines when the compressor temperature is not high, you can run it can be cooling, wait until the temperature of the compressor temperature protection Xuzhou on central air conditioning installation, then outside the fan still working, so you think outside the machine is still working, the substance compressor has been stopped) the reasons for this failure are: 1. The lack of quality reason itself outside the machine heat is not good freon 2. 3. compressors (new air conditioning that may be less) Second, the four-way valve is suddenly energized, into heating up. Provided that: out of the wind is really hot. The reasons for this failure are: 1. 2. PC board air conditioning line installation (small chance) common failure of split air conditioner air conditioner refrigerant compressor starts to run three minutes later, outdoor unit outside the valve, the liquid pipe condensation phenomenon, then run 10 minutes later, the trachea, the valve also appeared condensation Xuzhou Hisense air conditioning sales calls, indicating normal cooling operation the air conditioner, cooling system adequate refrigerant. If you start the air conditioner refrigerant compressor, hydraulic valves, hydraulic pipe frosting began a few minutes later, the frost has melted into a gel, run 15 minutes later, the trachea, the valve condensation phenomenon, indicating that the air conditioner cooling system a slight loss of fluorine, but also basic enough, generally do not need supplements refrigerant. If you start running after the air conditioner refrigerant compressor, hydraulic valves, hydraulic pipe frosting appears, over 15 minutes after the pipe, the valve also appeared frosting, indicating sufficient refrigerant in the cooling system, the indoor unit of the air filter too dirty, due to poor heat exchange effect. If the air conditioner refrigerant after compressor start after a start valve, liquid line appears frosting, frost after a few minutes, not only is not based, but the thicker end, running ten minutes, the trachea, the valve is still no condensation or frosting, indicating the refrigerant within the refrigeration system has a serious leak, the need for up-fluoro-operation. If the air conditioner refrigerant compressor start after running for some time, still no valve, liquid pipe condensation or frost, indicating the refrigerant within the refrigeration system leaks have all finished, the need for refrigeration system thoroughly serious leak, remove the drain After the point, and then refilling the refrigerant. When the air conditioner for cooling operation, when the refrigerant compressor starts to run 15 minutes, I'm airflow temperature should reach more than 8 degrees; 15 minutes after the compressor is running in winter heating, the import and export of gas flow temperature should reach 14 degrees, Description good heating and cooling effect of the air conditioner.
