WATER: A WORKING FLUID FOR CFC REPLACEMENT.

Author(s) : YUAN Q. S., BLAISE J. C.

Summary

ONE OF THE MOST IMPORTANT PROBLEMS HINDERING THE DEVELOPMENT OF HIGH-TEMPERATURE COMPRESSION HEAT PUMPS IS DISCOVERING WORKING FLUIDS THAT CAN BE USED IN THAT RANGE OF TEMPERATURE WITH THE NECESSARY CHARACTERISTICS. R114 CANNOT BE USED BECAUSE ITS CRITICAL TEMPERATURE IS ONLY 418.7 K (145.7 DEG C). R113 IS CHEMICALLY UNSTABLE. R21 IS CHEMICALLY ACTIVE AND ABSORBED BY SOME MATERIALS SUCH AS POLYMERS. THE AUTHORS PROPOSE THE POSSIBILITY OF USING WATER. THEY OUTLINE THE MAIN EXPERIMENTAL RESULTS, EMPHASIZING THE SYSTEM PERFORMANCES. THE RESULTS ARE ANALYSED ACCORDING TO EXERGETIC BALANCES, AND SOME TECHNICAL ASPECTS FOR HIGH TEMPERATURE HEAT PUMPS ARE GIVEN.
