Central air-conditioning duct cleaning process analysis machine into central air conditioning, hanging air conditioning, cassette air conditioner, cabinet air conditioners. These air conditioners, central air conditioning cleaning is the most difficult, is the highest natural clean-up costs. In it the central air conditioning, central air-conditioning duct machine, water machine. Duct cleaning machines are more expensive. 1, the return air filter cleaning disinfection 2, the air supply system disinfection. 3, fan coil cooler Xuzhou central air conditioning cleaning, cleaning, cleaning, sterilization central air conditioning with a special cleaning agent. Ventilate smooth 4, coil fan impeller, volute, sweeping the dust of the motor, the motor shaft refueling. 5, water butt plate, filter for removing sludge, debris, clean Xuzhou central air conditioning hire, maintain water flow 6, out of the wind gate clean. 7, check the plumbing connections are secure 8. Check the insulation is good 9, 10 check valve leaks, fan coil beneath fluorescent facilities do not install add refrigerant in air conditioners shift in Xuzhou central air conditioning parts, as long as the control operating specifications do After a good start running refrigeration, without adding refrigerant. But for the use of micro-leakage or shift due to slow movement when emptying the refrigerant will trace reduce or shift in the pipeline due to factors such as longer, the air conditioner in the running for some time can not meet the four conditions of normal operation that the pressure is lower than 4.9kg / (mm) 2 pipe frosting; Current reduction; the air temperature inside the machine does not conform to come, it would have to replenish the refrigerant. Add refrigerant in air conditioners transfer machine, as long as the control operating specifications do start running after cooling well, without adding refrigerant. But for the use of micro-leakage or shift due to slow movement when emptying the refrigerant will trace reduce or shift in the pipeline due to factors such as longer, the air conditioner in the running for some time can not meet the four conditions of normal operation that the pressure is lower than 4.9kg / (mm) 2 pipe frosting; Current reduction; the air temperature inside the machine does not conform to come, it would have to replenish the refrigerant.
