CORROSION, TOXICITY AND FREEZE CHARACTERISTICS OF UNINHIBITED DEGRADED PROPYLENE GLYCOL FOR USE IN CLOSED LOOP ACTIVE SOLAR SYSTEMS.

Author(s) : AVERY J. G.

Summary

TO PROVIDE GENERIC, ONE OF A KIND ACTIVE DOMESTIC HOT WATER SYSTEMS FOR THE MILITARY, SYSTEMS UTILIZING UNINHIBITED PROPYLENE GLYCOL WITHOUT FLUID MAINTENANCE WERE DESIRED. AN UNINHIBITED PROPYLENE GLYCOL WAS ARTIFICIALLY DEGRADED, AND CORROSION, TOXICITY, AND FREEZE CHARACTERISTICS WERE EVALUATE THESE RESULTS SHOW THAT, IN A COPPER SYSTEM, THE FLUID REMAINS NONCORROSIVE AND NONTOXIC. ADDITIONALLY, FREEZE CHARACTERISTICS REMAIN ESSENTIALLY UNCHANGED. THUS IT IS SHOWN THAT UNINHIBITED PROPYLENE GLYCOL, DESPITE DEGRADATION, IS A SUITABLE FLUID FOR USE IN ACTIVE SOLAR SYSTEMS WITH LITTLE OR NO FLUID MAINTENANCE.
