Frigorigènes pour remplacer le CFC-12 dans le conditionnement d'air automobile.

Alternatives for CFC-12 refrigerant in automotive air conditioning.

Auteurs : JETTER J. J., DELAFIELD F. R.

Résumé

Ten refrigerants including CFC-12, HCFC-134a, and eight refrigerant blends were tested in an instrumented automotive air-conditioning system designed for CFC-12. The refrigerants were compared at three test conditions for refrigeration capacity, COP, compressor discharge pressure, compressor discharge temperature, and evaporator outlet pressure. Due to limitations of the testing, test results should be not used as conclusive evidence of the performance of refrigerants. However, the results were obtained by testing all the refrigerants in the same system under the same conditions, and the results provide an indication of the comparative performance of the refrigerants. Refrigeration capacities for CFC-12 substitutes ranged from 9% lower to 9% higher than capacities for CFC-12. Detailed results are given.
