Welcome to call the Shanghai Baoshan air conditioning and refrigeration repair phone, Shanghai Baoshan Chunlan, Gree, Haier, Hitachi, Sharp, special air-conditioning repair phone 021-22816736 
 Refrigeration repair air conditioning installation on the Hai Kejie services company. Air conditioning is an important factor is the refrigerant, which is the fluoride, the amount of snow, good or bad impact on air-conditioning cooling effect, snow and changes in the inspection is to note. The following six issues plus the snow when the air is often encountered. A: air-conditioning installation and maintenance of ordinary people do not know how to identify air-conditioning refrigerant has not been filled? 1, installed air conditioning to the normal state in the refrigeration, air conditioning on a machine outside the two connectors are drops of water? There, normal; a one no, lack of fluoride; not, fluorine-free. 2, open the inner cover, remove the filters, which have brass drops, normal; knot of white frost, lack of fluoride; nothing, fluorine-free. 2: How to fluoride 1 with sufficient fluorine refrigerant cylinder hose connection, pressure gauge and filling fluoride mouth, remove the air hose. (2) Start the compressor, the use of cylinder pressure difference with the cooling system to add refrigerant. 3 charged fluorine were observed during the pressure gauge pointer changes to remain at 0.45 ~ 0.5MPa. 4. 30 minutes after the test run, observe whether the air conditioner into working order. 5. Stop the leak after the review of doubt, no leakage can be put into operation. Three: the need for air conditioning plus snow each year? Basic need air conditioning plus a refrigerant per year, in case of moving, job transfers and the transfer of air-conditioning installation work, installation of local restrictions, air conditioning pipe extension, disassembly, etc. must be emptied refrigerant consumption, resulting in insufficient refrigerant. The amount of refrigerant charge into the air and air-conditioning cooling capacity has a close relationship, plus the snow should be tailored to the circumstances. Four: the amount of air conditioner refrigerant added too much or too little can cause what circumstances? Adding excessive air-conditioner refrigerant, can cause: running high humidity, condensation prone to anomalies. Reciprocating compressors or air conditioners may be condensation on the shell, rotary compressors in air, condensation, etc. on the liquid separator. Air conditioning compressor load increase, in the case of overload, air conditioning compressor will stop running after a while. Increased power consumption. The amount of refrigerant charge into the air, this could cause: air conditioning refrigerant discharge temperature is too high, resulting in deterioration of refrigerant oil deterioration. Insufficient air conditioning. Air conditioning compressor motor winding temperature, winding burn accident prone. V: not enough snow types, whether to continue the air-conditioned, then it will hurt the machine? Will affect the air conditioning compressor. The cooling is by air-conditioning compressor to cool the refrigerant, if the refrigerant compressor cooling is bad enough, the compressor speed on the heat from the compressor in life expectancy. VI: air conditioning refrigerants, plus enough, but not very good cooling effect, is there a problem? Air conditioning cooling effect of poor for the following reasons: 1, less than 2 liquid cooling system, the system slightly to plug 3, 4 within the fan network congestion, poor heat dissipation outside the machine 6, the temperature control circuit failure 7, 8 within the fan speed too slow , Room 9 is too big or poor insulation, too much liquid refrigerant 10, when the exhaust is not installed 11 air-conditioned, four-way valve 12 series gas, power supply voltage instability In addition, the use of air conditioning when reasonable, correct, love the use of will extend the use of refrigerant time, increase the service life of air conditioning.
