The operation of central air conditioning system and the harm of scale to the system

The operation of central air conditioning system and the harm of scale to the system As we all know, any water filtration machine we use will produce scales, such as drinking fountains. When scales form in the system during long-term use, it will cause great harm to the system itself. The central air conditioner is no exception. Here is a brief introduction to how the central air conditioner works and how the scale damages the system. The central air conditioning circulating water system is divided into two circulating systems: cold, hot, plum water and cooling water: (1) Because the cooling water system is exposed to the atmospheric environment and runs in the tower pool, it is very easy to breed microbial algae fouling. At the same time, both systems change with the continuous concentration of impurity ions in the water and the temperature changes. This will inevitably lead to the system pipe Wall fouling or corrosion has deteriorated the operating conditions, reduced the efficiency of the operating system, increased energy consumption, increased faults, increased maintenance work, and greatly shortened the service life of the equipment. (2) The central air conditioner uses a refrigerant system, which is generally a closed cycle. There is almost no loss of water in the middle of the system. The problems with this system are whether the rust breeds algae to produce slime or scale, all of which increase The heat resistance of the heat exchange pipe reduces the heat transfer efficiency; the heat exchange efficiency of the unit will be obvious, such as a lithium bromide refrigerator; when the thickness of the cooling water pipe dirt decreases significantly, the cooling capacity decreases 1. The harm of scale in the central air conditioning system to the system The cooling water in the central air conditioning system; if the chilled water is untreated, the oil is extremely corrosive; the central air conditioning system pipes and equipment inner walls often cause rust slag to fall off due to corrosion; even perforation; the rust slag falling in the system will It is easy to block the tube coil to reduce the operating effect of the central air conditioning system, and the presence of corrosion greatly reduces the service life of the equipment. Crystals of inorganic salts dissolved in water in the central air-conditioning pipeline are precipitated; the condenser in the central air-conditioning cold storage system; scales are formed on the wall of the surface cooler and the increase in the hard scale in the system reduces the heat exchange efficiency; the cooling effect is reduced; colleagues The increase of hard scale will increase the power consumption of the system during daily operation or increase the consumption of the system's compressor. ; The system has some impurities in the water (soil; sediment; humus formed by impurities after Hanjie formation; plus biological slime formed by microbes such as bacteria and algae and their secretions, causing pipeline blockage in severe cases; In winter, it is easy to cause pipeline cracking; increase the amount of maintenance of system equipment, dirt and slime will affect the heat exchange efficiency; the effect of the amount of money will obviously reduce you; consume more electricity than usual; long in the system All the use of time will increase; the energy consumption will increase; the local effects of the air conditioning system will be particularly poor; the occurrence of these conditions will seriously affect the normal operation of the entire central air conditioning system; we are using the central air conditioning system The water treatment is an indispensable part.; The major brands of central air conditioning generally use Emerson Copeland compressors, and the quality of Copeland compressors is also famous in the world.
