COMPARATIVE PERFORMANCES OF R134A AND R12 IN A RECIPROCATING WATER CHILLER.

Author(s) : ARNAUD D., CAILLIE J. P.

Summary

THE AUTHORSHAVE DESIGNED AND TESTED AN EXPERIMENTAL 15 KILOWATT WATER CHILLER EQUIPPED WITH A SEMI-HERMETIC RECIPROCATING COMPRESSOR CHARGED WITH NAPHTENIC MINERAL OIL. A GOOD AGREEMENT WAS OBSERVED BETWEEN THE DIRECT MEASUREMENTS OF THE TOTAL ENERGY CONSUMPTION OF THE COMPRESSOR AND OF THE REFRIGERATING CAPACITY OF THE EVAPORATOR AND THE PERFORMANCES DEDUCED FROM MEASUREMENTS ON THE REFRIGERANT CIRCUIT. COMPARATIVE THERMODYNAMIC PERFORMANCES WERE REPORTED AND DISCUSSED FOR BOTH R134A AND R12 OVER A COLD GLYCOL WATER TEMPERATURE RANGE OF 263 TO 278 K (-10 TO 5 DEG C) AND FOR A CONSTANT CONDENSATION TEMPERATURE OF 305.5 K (32.5 DEG C). AFTER 500 HOURS OF CONTINUOUS OPERATIONS IT WAS NOT OBSERVED ANY MECHANICAL OR PERFORMANCES DISFUNCTIONING DUE TO THE NONMISCIBILITY OF R134A WITH THE OIL.
