What it needs to add refrigerant air conditioning does what it needs to add refrigerant air conditioning it? Some people think that air conditioning cooling effect is to add a secondary refrigerant in air conditioning, in fact, not the case, air conditioning and refrigeration effect is not good, there are many cases, such as the four-way valve string gas, compressor leak, capillary blockage, etc. are possible The following specific analysis of air conditioning not cooling: air conditioning refrigeration case there are many, there are three situations: First, the voltage is too low, can not run the air conditioning supply voltage; the second is the air conditioning unit environment is poor, resulting in blockage of ventilation is not outside the machine Chang; three is the lack of fluoride. "The first two cases occur frequently, and air conditioning because of the lack of fluoride is not really the case less cooling." Wang said, residents of the home's air conditioner is not cooling, first find the first two reasons, and often clean air filter. "If there is frost on the straw air conditioning unit, it is likely to be true lack of fluoride;. If you are unsure, ask a professional repairman detection measurement tools," Wang said. Before practice home hanging air conditioning deactivated during long periods, should be opened, air conditioning repair windshield Xuzhou used to dry the moisture inside the indoor unit; unplug the power plug, remove the batteries in the remote control; able to do so, with cover The inner and outer hood up to keep the indoor and outdoor heat exchanger cleaning. Before the arrival of the season, to be on the air conditioning check-ups. First, remove the cover included, cover the outside machine, the indoor and outdoor air inlet, an outlet on the obstacle is removed, and then loaded on the remote control batteries, the power is turned on the air conditioner, air conditioning boot after observing run correctly. Air shift attention to what moves when confidential deliberately brass split off, get a new pipe to deceive customers. Deliberately valve does not open or semi-open to loss of fluorine in the name of increased costs, such consequences or cause performance degradation when the compressor is bad, or when the four-way valve moves, such as wiring and heating in winter and then unplug the door to deceive customers. Before moving machine is a good second-hand air conditioning rental Xuzhou, the machine is broken or can not afford or remote failure and refrigeration after transfer machine / thermal effect is poor, it is a small relocation experience and technology, however, the consequences will burn out the circuit board. How much horsepower for air-conditioning repair, how much fluoride, current much, much power, cooling / heat did not know how many calories Xuzhou hand air conditioning installation, just mechanical maintenance, not theory with practice, so that failure due to small and large, that machine scrapped. Based on the above examples, I remind customers of wedding dresses, looking for regular maintenance company.
