Abstract

Objective: Through the test of air conditioning cooling water circulation system and the electrical conductivity of iron corrosion velocity, find out the method of corrosion control measures; Methods: Rotating hanging plate method and conductivity meter and other cooling water test air conditioning system in different conductivity of metal iron corrosion rate; Conductivity results: Air-conditioning cooling water circulation system of more than 1900 μs/cm, metal corrosion rate less than 0.05mm/a, shall meet the relevant standards. Conclusion: Through the addition of corrosion inhibitor, scientific emission and control of circulating cooling water pH, conductivity decreased circulating water cooling, can reduce the corrosion of iron, to ensure the safe and stable operation of cooling water pipe and equipment.
