Indoor air outlet temperature is too high (heating) troubleshooting method, check the air conditioning duct system is fouling situation exists, if there is a corresponding adjustment is performed; 2, check the air conditioning electric auxiliary heat is abnormal work, namely air conditioning evaporator probe the detected temperature is high or have been open, if it indicates electric auxiliary heat control system failure, the need to check the air conditioning circuit boards; air conditioning energy efficiency as high as possible is not generally required consumers to buy air conditioning energy efficiency considerations, in fact Xuzhou professional air conditioning maintenance, air conditioning Not when you use the higher the EER, the better. It is understood that air conditioning can achieve the best power saving Xuzhou central air conditioning maintenance, to be based on individual household usage to measure. Generally, a small one and one air conditioning 10 hours of continuous work to save 1.5 kWh central air conditioning, every day do not need to use so you do not need a long time family deliberately chose most energy-efficient products. And currently on the market one and five energy-efficient air conditioning price level would be able to more than a thousand dollars difference, so the use of family time is very short, some 4-5 grade energy efficient air-conditioning also be considered. Meanwhile, some experts pointed out that the two energy efficiency is actually a "critical point", according to estimates Xuzhou transformation of central air conditioning, general household use two energy efficiency air conditioning energy saving effect is usually best. 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 on the high temperature to protect the compressor, and then outside the fan still working, so you think outside the machine is still working, the substance of the compressor has stopped a) The reasons for this failure are: 1. Cause 2. lack freon cooling outside the machine itself, the quality is not good 3. Compressors (new air conditioning that may be less) Second, the four-way valve is suddenly energized into heating a. 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) transformation of central air conditioning refrigeration Xuzhou Sheng Erda _ _ central air-conditioning is provided by Xuzhou 圣尔达 Refrigeration Electrical Services Limited.
