A SURVEY OF WATER QUALITY AND ITS EFFECT ON FOULING IN FLOODED WATER CHILLER EVAPORATORS.

Author(s) : HAIDER S. I., WEBB R. L., MEITZ A. K.

Summary

A PROGRAM INVOLVING FIELD SAMPLING AND ANALYSIS WAS CONDUCTED TO DETERMINE THE WATER QUALITY USED IN WATER CHILLER EVAPORATORS. THE AUTHORS THEN INTERPRETED THE DATA TO INFER THE POSSIBILITY FOR WATER-SIDE FOULING RESISTANCE IN THE EVAPORATOR TUBES. THE PROBLEM INVOLVES THE TUBE-SIDE FOULING IN COPPER TUBES WITH 5-10 FT/S WATERFLOW AT 5.5-11 DEG C. THE WATER-QUALITY TESTS WERE CONDUCTED TO DETERMINE THE POTENTIAL FOR PRECIPITATION,BIOLOGICAL, CORROSION AND PARTICULATE FOULING. WATER SAMPLES WERE TAKEN FROM 71 CHILLERS IN 31 US CITIES HCETA THE RESULTS WERE THEN ENTERED INTO A COMPUTER DATA BASE. RELATIONS BETWEEN FOULING AND NUMEROUS FACTORS WERE FOUND. STATISTICAL PARAMETERS WERE TABULATED. THRESHOLD VALUES FOR FOULING WERE DEFINED.
