　　　Central air conditioner system Condenser in central air conditioner system will gradually form a layer of scale on the water side. The longer the condenser is used, the harder the water quality, and the thicker the scale thickness. Because the scale has a small thermal conductivity coefficient, it affects the heat transfer effect of the condenser, resulting in poor cooling effect of the freezer . Therefore, corresponding measures must be taken to remove the scale technical difficulties on the water side of the condenser. Traditional methods of removing scale from the water side of the condenser are manually scrubbed, mechanically and chemically cleaned. In recent years, some shopping malls have installed the electronic water treatment instrument . Due to the working principle of the instrument itself, it is determined that it cannot remove impurities in the water. Only by discharging sewage can the purpose of preventing and descaling, and air conditioning operators often ignore this point. This is a misunderstanding that an electronic water treatment instrument is installed without the need for sewage discharge.

　　The use of cold source equipment in the shopping mall central air conditioner system will be considered based on factors such as power supply, investment, and building scale. If the survey user maintains it from these aspects, it will extend the service life of the air conditioner equipment and slow down the speed of cooling efficiency
