Guangzhou Gree Central Air Conditioning Cleaning and Maintenance
Release time:2019-09-02 | Source:HUA LI JI DIAN.Introduction to the central air-conditioning cleaning in Guangzhou Gree1、Central air conditioning cleaning and disinfectionTo the central air conditioning to carry out a comprehensive cleaning, purification and disinfection can provide good air quality, the establishment of a control and prevention system to prevent viruses through cross-infection of air conditioning, completely eliminate the perennial hidden dangers of pollution sources, to ensure the quality of life, working conditions and human health.
2、Cleaning of the central air-conditioning ventilation systemCentral air-conditioning ventilation system mainly includes ducts, new ducts, central air-conditioning air cabinets, air vents, air treatment units, fan coils and so on. For a long time people have ignored the central duct cleaning, in fact, in the air-conditioning duct shaded for two or three years has long been affected by germs, dust, oil scale. Only the central air-conditioning duct system for systematic and comprehensive cleaning, purification and disinfection can provide good air quality. After SARS to carry out central air-conditioning cleaning work, can make office buildings, hospitals, shops, hotels, factories and other public places to establish a control and prevention system to prevent viruses through air-conditioning duct cross-infection, completely eliminate the perennial existence of pollution sources hidden dangers.
Guangzhou Gree central air-conditioning cleaning benefits
Because of the long-term untreated central unit due to scale, rust, pollution, often cause the air-conditioning host high-pressure operation, causing a fault shutdown, interrupt the air-conditioning supply, serious or even cause the host corrosion perforation, solution leakage. And repairing the host will cost a lot of money.
Huali electromechanical in the central air-conditioning cleaning case to take the capacity of 1 million cards of the central air-conditioning unit made a comparative analysis of the image:
The power saving advantage of central air-conditioning cleaning. One millimeter of scale will reduce the cooling capacity of the unit by 20-40%, while the condenser pressure increased, resulting in increased motor load, energy consumption of 10-30%, if the unit capacity is 1 million cards, equipment energy efficiency ratio of 3.2kw, 10,000 cards, the average load of 80%, a year running a total of 5000 hours, Then a year need to consume more electricity - 12.8-384,000 degrees, to 0.8 yuan per degree of electricity, the annual waste of electricity costs 10.24-30.72 million yuan.
The low-loss advantage of central air-conditioning cleaning can extend the service life of the unit and reduce the depreciation cost of equipment. The durability of the main components of the central air-conditioning unit is slightly different, the experiment shows that the new unit after prevention treatment, the average durability of the equipment doubled, the water treatment in the middle, the average durability of the equipment can be extended by about 40%. If a set of central air-conditioning unit price of 1.5 million, without water treatment when the unit durability period is about 7 years or so, then the average annual equipment depreciation cost is about 210,000, after water treatment, the durability period can be extended for about 3 years, then the average annual depreciation cost of about 150,000, equivalent to the annual reduction of equipment depreciation costs 60,000 yuan.
After the central air-conditioning cleaning, can effectively remove and control rust, scale, microbial pollution phenomenon, so that condenser copper pipe to keep clean, in the best heat exchange state, reduce the wind turbine coil blockage, avoid failure, reduce maintenance costs, ensure the healthy operation of the unit, so as to ensure that the central air-conditioning owners of normal production and life.

Guangzhou Gree Central Air Conditioning Cleaning Technology
With the wide application of central air conditioning, central air-conditioning has become a transmission channel of infectious diseases, according to domestic statistics, each summer suffering from air-conditioning diseases and the number of infectious diseases transmitted by the central air-conditioning channels more and more, seriously endangering people's health, so, for your and the health of your family, Please clean up our easy-to-ignore places, especially where dust and bacteria inside the air conditioner are out of our consciousness.At the same time, the water quality problem of the water system will bring a lot of harm to the operation of the central air conditioning system. Frozen water system because of the corrosion, it is very easy to cause coil blockage, unit and pipeline accessories corrosion, affecting the normal operation of the system. Air-conditioning cleaning has become a problem that can not be ignored.

Steps for the cleaning of central air conditioning in Gree
Central air-conditioning cleaning generally includes frozen water, cooling system cleaning descaling, water treatment, lithium bromide unit cavity cleaning treatment, replacement of new solutions, old solution regeneration, central air-conditioning fan coil cleaning. The scale and blockage are hard and difficult to clean, the column tube is heavily blocked, even more than 20% of the tube bundle, the small tube diameter of the heat exchanger (column tube diameter of less than 12 mm).
1、Sterilization: Remove strains and algae from circulating water by adding bactericidal agents to the circulating system.
2、Muscous peeling: Add the peeling agent, peel off the bio-mud in the pipe, and clean the muds out through a cycle.
3、Chemical cleaning: add chemical cleaning agent, dispersant, the pipe system of aerosol, scale, oil cleaning down, scattered discharge, reduced to a clean metal surface.
4、Surface prefilm: put into pre-film agent, in the metal surface to form a dense polymer polymer protective film, to play a corrosion-proof effect.
5、Daily maintenance: add corrosion inhibitors to avoid metal rust, while adding scale inhibitors, through a combination of action, to prevent calcium and magnesium ion crystallization precipitation. And regular sampling, monitoring water quality.Pre:NothingRelevant information
