Abstract

The present invention provides an intelligent processing method and system for central air-conditioning cooling water, which uses corresponding sensors to collect water quality parameters in cooling water heat exchange tubes in real time and feeds back the collected data results to the server for data analysis and processing. The analysis result of the data further controls whether to perform the descaling action. After descaling the cooling water heat exchange tubes, the acid-base neutralization of the water in the cooling water heat exchange tubes is also carried out and the pH of the water quality is detected in real time, so as to control when to interrupt the neutralization operation and realize precise control of cooling water exchange. The amount of chemicals added to the heat pipe; in addition, this solution also judges whether the heat exchanger needs to be cleaned by performing pressure detection on the water quality in the cooling water heat exchange pipe after descaling. Due to the high degree of automation of the above-mentioned whole process, real-time data collection is carried out on the cooling water heat exchange tube, so the cooling water heat exchanger can maintain a normal pH value for a long time and minimize the occurrence of corrosion.

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...
