Teach you how to diagnose air conditioning is not the lack of fluoride air conditioning freon refrigeration and heat are needed to help, so once the lack of freon air conditioning maintenance and installation of Xuzhou, air conditioning will be a series of reactions, such as the cooling effect decreased significantly. Serious or even air conditioning compressor does not start automatically protected. So the lack of fluoride for an air conditioner is a very serious problem, here are a few ways to judge conditioning lack of fluoride. 1. The low-pressure pipe (crude pipe) dry, touch the air conditioning repair, and no ice feeling. This is because of the lack of freon, the evaporator which reduces the boiling point of the refrigerant, the refrigerant temperature of the low-pressure pipe in the valve increases. 2. The high-pressure pipe frosting. The reason is that the pressure drop within the tube, a lower boiling point, the high pressure pipe temperature is below freezing, the air in the water turns into ice. 3. Turn on the machine panel, remove the filter, naturally you can see above the evaporator frost. If frosting is less area is small, indicating lack of refrigerant resulting in reduced cooling capacity. The outdoor unit without thermal exhaust. The reason is lack of refrigerant Xuzhou wedding dresses fluoride, resulting in condensing pressure and temperature. 5. Drain the machine Xuzhou central air high-profile maintenance, less water, or simply no water. This is because the lack of fluoride leads to decreased cooling capacity, the condenser can not condensate. 6. From the outdoor unit charge fluoride mouth measured pressure is lower than 0.45MPa. The reason is that the refrigerant shortage, leading to the evaporation pressure drops. If only the low-pressure gas pipe valve frost, proved to be only a trace amount of lack of fluoride, the ambient temperature is too low; two valves are frost, indicating the system has secondary throttle phenomenon.
