Air conditioning and heating automatically shut down when the air conditioning and heating usually start at the opening mechanism stopped or parked heat just blowing hot air, the red light flashes. Brand machine, air-conditioning more common. US air-conditioning repair air conditioning and heating for the automatic shutdown also lists some of the overhaul of focus: 1, the machine outside the machine heat exchangers and heat sink dirty overload caused by air conditioning; 2, press start capacitance loss Xuzhou central air conditioning installation, thermal protection occurs as early as the press run for a period of time; 3, system problems, such a situation, there are two: ① high and low collusion, only the four-way valve at the micro block ② system, there is one-way valve and the main 4, press the problem;; 5, the temperature sensor on both sides of the filter at the capillary tube. Compressor heat from the refrigerant compressor repair method for R22. Indoor temperature of 10 degrees, the outdoor ambient temperature of about 31 degrees, the compressor run time working pressure 3.1kgf / cm2 and 14.2kgf / cm2, low pressure shutdown is about 6.8kgf / cm2, the compressor is running a three-phase current of 9.13 A / 9.35A / 9.52A, compressor surface temperatures over 100 degrees, after a period of time to protect the compressor is running, what is the reason? Obviously the lack of fluoride, low suction pressure, overheating degree. In home air conditioning use, many users are aware of the problem wind conditioning set? Set the air conditioning airflow is blown up or down or horizontally blowing blow then? For this problem, Jinan conditioning repair has held its own point of view: Summer winds should hit the top, because the cold air than the major air conditioning, will go down from. Hot start to the winter, we should hit below the wind, hot air is lighter, will go up from the bottom, the entire room will be warm. Winter air temperature is critical, then the air conditioning and heating also pay attention to some small tips. First of all, a reasonable set temperature helps air conditioning energy: Under normal circumstances when setting low 2 ℃ heating, although the body does not feel very obvious, but the air conditioning, the average can save nearly 10% of the electricity. Secondly, we must pay attention to adjust the air conditioning wind speed, wind direction: the just-conditioning, wind speed can be set to high wind speed, air and room air conditioner to accelerate the process of heat exchange, when close to the set temperature, wind speed can be set to low speed, Xuzhou Air Conditioning repair parts, this will save some energy. Vary the proportion of hot and cold air, so it is best to let the wind down during the heating air conditioning air conditioning repair Xuzhou, in order to improve the exchange of hot and cold air, to save battery power. In addition, the doors and windows closed when the air conditioning, a long time can cause indoor oxygen, bacteria, viruses, also took the opportunity to accumulate a lot. Therefore, we advise you to Jinan air conditioning repair air conditioning more than two hours should be stopped and ventilation window.
