Green Composite Scale Inhibitor in Central Air Conditioning Cooling Water

Abstract:

With the improvement of living standards, air conditioning becomes the requisite of people’s life; the central air conditioning has become each big building of major appliances[1]. In the whole air conditioning cooling water treatment system, such as scale and sludge which is formed by the metal corrosion phenomenon, will seriously affect the use efficiency of air conditioning. One of the effective solution is adding scale inhibitor to the circulating water. Calcium carbonate deposition method is used to evaluate the scale inhibition rate of PASP, PESA and poly glutamic acid. then evaluate the scale inhibition rate of two compound formula. Results show that PESA with the best scale inhibitor performance, on the basis of its, respectively, compound with PASP and poly glutamic acid. The compound repice can improve the efficiency of scale inhibition. The optimized prescription is that, the PASP is 4mg/L, the PESA is 6mg/L, at this time of scale inhibition efficiency can reach 93.43%.
