Is a widely used in recent years, the method of low operating costs, easy to use, easy to control, no pollution is a more ideal water treatment methods, in fact, foreign countries as early as the 60s will be the attention of the chemical methods to the development of physical methods. At present, the application of physical methods are magnetic method, electrolysis, ultrasonic method, electrostatic method, etc.
Can inhibit the adhesion of scale, but the scale is not complete, and has the risk of electrolytic pore corrosion; early application of the magnetic method of stability is poor, long time use can not control the accumulation of scale, must be regularly cleaned in the controller collection of iron oxide; and electrostatic method to overcome the shortcomings of the above methods, and, in addition to scale and scale dissolution, there are significant sterilization and algae efficiency. However, electrostatic method and electronic water treatment method of corrosion inhibition than the special chemical corrosion inhibition is slightly lower, in the general air conditioning cooling water system can not consider using other corrosion inhibition methods, and in some of the higher requirements for corrosion inhibition system is best to add some corrosion inhibitor in the right amount, can get better results.
Although the piping arrangement of air conditioning cooling water system is relatively simple, but if it is not well thought out, there will be some problems. As the circulating cooling water system is an open system, if the volume of the cooling tower collection plate is small or the distance between the cooling tower and the pump is too far and the resistance balance of the cooling tower outlet pipe running in parallel is seriously out of balance, it will make the air mix into the water, enter the pump and press into the pipe, causing serious water hammer resulting in damage to the pump outlet pipe and its fittings.
Cooling towers used in parallel when the pipeline resistance balance, the distance between the cooling tower and the pump can not be too far; pump should be arranged in front of the chiller (that is, cooling water pressed into the chiller); and, the pump should be made into a self-filling type; avoid the pump suction pipe up and down to turn the bend. In addition, the cooling pump, chiller, cooling tower should be made one to one correspondence, in order to facilitate the regulation and flow balance, if the above control can not be achieved, automatic control system should be used, the import and export of cooling tower should be set up at the solenoid valve, and should be synchronized with the opening and closing.
Or in each cooling tower into and out of the water pipe set balance valve to ensure that the water into each cooling tower to meet its rated flow. In order to improve the water collection of the suction pipe, the design of the suction pipe can be appropriate to increase the diameter of the suction pipe.
