Central air-conditioning professional maintenance cleaning project

In order to improve the heat exchange efficiency of the outdoor unit of air conditioner, prevent or reduce the dust, the indoor and outdoor air conditioning system of the air conditioner should be cleaned and maintained regularly. In recent years in the maintenance experience, the correct maintenance methods can play an excellent role, mainly in the:

1, regular cleaning and maintenance can improve the quality of indoor air, prevent disease epidemic, create a healthy indoor environment. The air conditioning system after a long time running, including machine filter, filter and evaporator area will gather a large number of dirt, easy to breed and breeding bacteria, and then by air blown indoors, pose a threat to human health.
2, cleaning and maintenance of the system can effectively reduce the noise pollution. With the deposition of dirt indoor return air filter and other parts of the attachment and fiber material, blocking filter and fin, and fan blades on the dust, these have greatly increased the fan and motor load, causing noise.
3, can improve the heat transfer efficiency of the system equipment, improve the cold and hot effect, to achieve effective energy saving. If the evaporator inside and outside the machine and the heat exchanger is not cleaned for a long time, the attached dirt will greatly reduce the thermal conductivity of the equipment, seriously hinder the efficiency of heat exchange, at this time, the load of the compressor increases dramatically, energy consumption will increase.
4, can eliminate the hidden trouble of the system, reduce the failure rate, prolong the service life of the equipment, spend a little money, save money. The composition of the air conditioning system is complex, but it is mainly composed of three parts, including refrigeration system, driving power supply and control circuit. No matter which part of a problem will affect the normal use of air conditioning, correct and timely maintenance and maintenance work, will discover the hidden and processing of three parts, the machine is always in good working condition, low failure rate, prolong life.
Maintenance / maintenance
According to the condition of the equipment, the maintenance work mainly includes two parts: Inspection and maintenance:
1, check
1) operating pressure: exhaust suction pressure
2) whether the terminal row or its joint is aging and loose, whether or not the connecting line is broken off;
3) internal and external machine interface has no fluoride;
4) running noise is normal;
(5) insulation resistance (or even the copper pipe to the ground between the AC induced voltage);
6 return air temperature, air temperature, outdoor temperature of the relationship between the three is normal;
7) whether the condensate drainage is smooth;
8) whether the filter is dirty or not;
2, maintenance
1 clean the inner panel, the filter, the evaporator and the shell, condenser, etc.;
2) remove the dust from the control panel, adjust the contact state of the line and the position of the pipeline;
3) replace worn or damaged parts;
4 (if necessary) to increase refrigerant or replace refrigerant oil.
3, working method:
1 indoor machine cleaning filter using disinfection, once a year.
2 outdoor machine to remove dust or smoke scale so that the circulation of air flow, two times a year. Reduce energy consumption and prolong service life
3 eight pass inspection: the terminal or other terminals without loosening and aging; II. Operating pressure; the internal and external interfaces are no leakage of fluorine; the check abnormal noise; the insulation resistance; the inlet and outlet air temperature and outdoor temperature; the water drainage is smooth; the filter is in the machine smooth.

4 use the special cleaning gun for air conditioner, adjust the appropriate pressure and nozzle shape according to the thickness of the heat exchanger. Finally, we will be free of charge in the cleaning of the new air conditioner, such as special air conditioning refreshing agent, so that you have a long period of warm and fragrant spring air.
