Machine evaporator dirt inside air conditioning and cleaning method
If can is best don't wash adjust, because the machine have corrosion, with pressure pipes directly rushed!!!!!! If you don't clean water, such as soot... Dust can be on the air conditioning radiator fantasy "polyester" after a few minutes with pressure water clean! Please cut off the power supply for the operation of all!!!!!!!!!!!!!!!!!!! Be on the safe side.
Fault condition: refrigeration effect is not good, almost feel wind speed. Fault analysis: air conditioning has been used for many years, is not installed at the beginning, so can be ruled out of design or installation errors (some air conditioning fluorine injection pressure is not enough or install valve tight can also result in refrigeration system failure, leading to poor cooling effect). Air conditioning use place as a knitting workshop, the air conditioning of electric control board and power supply, freon, and so on and so forth of illness, have not found the problem. When the air-conditioning outlet screen again found that the temperature on the high side, analysis may be caused by air volume is too small. It has already been carried out on the air conditioning of electric control board, the cause of air volume small also may be a dirty wall motor fault or evaporator. Through layers of screening and found the evaporator surface glue has a lot of wire cloth with soft nap, accompanied by frost. Debugging methods: completely remove dirt machine evaporator, bootable again, refrigeration effect is very ideal, and wind speed has returned to normal. Experience: some dust, soot, more environment was the cause of bad air conditioning refrigeration smudgy, therefore maintenance when this kind of air conditioning to adjust measures to local conditions, from the perspective of the peripheral environment, first screening condenser, evaporator, filter, such as whether the dirt, two, and capillary for the junction box, etc., this will make the repair work get twice the result with half the effort. Online to find information... Hope to have help!!!!!
The main steps are as follows: 1, clean air conditioning to open air conditioning before 15 minutes, so that air conditioning start cooling, at the same time make air conditioning evaporator condensate. After turn off air conditioning, to cut off the power supply to ensure safety. 2, open the shell of air conditioning, remove the strainer mesh, clean with water. 3, clean the evaporator, if the heavier dust evaporator finned, can use soft brush to remove it again first. Again on the evaporator finned aluminum heat transfer surface coil and spray air cleaner, ensure clean foam evaporator surface completely. 4, about 15 minutes later, the air cleaner can fully penetrate reaction, fully disintegrate on air conditioning evaporator finned stubborn dirt, then wipe with a soft cloth. 5, and replace the strainer mesh, and cover the air-conditioner shell, and then with a soft cloth dipped in warm water and gently wipe the air conditioner panel, don't too hard, in order to avoid damage to the coating on the panel. 6, open air conditioning, and the air volume and the refrigerating capacity to the maximum, kept open air conditioning, 10 to 20 minutes from sewage drain discharge.
