Abstract

The invention provides an intelligent processing method and system for central air-conditioning cooling water. Corresponding sensors collect quality parameters of water in a cooling water heat exchange tube in real time and feed the collected data results back to a server for data analysis and processing, and the server controls whether descaling is carried out according to the data analysis result. After descaling is carried out on the cooling water heat exchange tube, acid-alkali neutralization is carried out on the water in the cooling water heat exchange tube, the pH value of the water is detected in real time, and therefore the time of interrupting the neutralization operation can be controlled, and the quantity of agents added into the cooling water heat exchange tube can be accurately controlled. In addition, pressure detection is carried out on the water in the descaled cooling water heat exchange tube so as to judge whether a heat exchanger needs to be cleaned. Because the whole process is high in automation degree and data collection is carried out on the cooling water heat exchange tube in real time, a normal pH value of the cooling water heat exchanger can be kept for a long time, and corrosion can be reduced to the maximum degree.

Description

technical field [0001] The invention relates to the technical field of air-conditioning heat exchange equipment, in particular to an intelligent processing method and system for central air-conditioning cooling water. Background technique [0002] After the cooling water in the traditional central air conditioner is used for a period of time, there will be structural phenomena on the heat exchanger pipes, which will affect the heat exchange efficiency of the heat exchanger. For this reason, the existing general treatment method is to carry out treatment by adopting chemical methods, and its treatment time, frequency and dosage of chemicals all rely on personal experience to judge completely. This existing method has the defects of improper use of chemicals and easy pollution of the environment. At the same time, when the dosage of chemicals is used too much, it is easy to cause corrosion of the tube wall of the heat exchanger and reduce the service life of the heat exchanger...
