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 on the high temperature protection, then outside the fan still working Xuzhou used central air conditioning renovation, so you think outside the machine is still working, the substance of the compressor has been stopped) 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 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) air-conditioned indoor air guide plates running water droplets Analysis: If the air conditioner set to the cooling operation, while opening the deflector to swing up and down or run down the deflector angle-modulated long hair. When the ambient temperature is high or the air humidity, the air conditioner indoor air guide plates will produce heat outside cool down the formation of water droplets dripping. Proper use: air conditioning and refrigeration to adjust the angle of the wind deflector blowing horizontal position. After a period of indoor air conditioning and heating cold blow chance this is normal phenomenon for the outdoor unit defrosting hand air conditioning, when defrosting the outdoor unit, indoor chance to stop working, the wind blowing heat temperature around 23 degrees, since the original outlet temperature quite different, so the body feels cool breeze blowing in Xuzhou used central air conditioning repair, this is normal, you can use it. When the air conditioning and heating outdoor unit outdoor unit does not defrost find air conditioning and heating outdoor unit frosting frosting how many there are major relationship with the outdoor air humidity, in addition to the boot time is longer, the higher the set temperature, the air conditioner reach temperature stop operation will be relatively thick frost (especially been turned on at night, lower night temperatures, higher humidity frost will more) dehumidifying the air conditioner drains undrained this issue should be set up on the problem machine, dehumidifying Air conditioning needs to be set up in 16 degrees, and then select the dehumidification mode, of course, you can also turn on the heating effect of dehumidification, the need to look at the local weather conditions.
