Challenges and opportunities of implementing alternative refrigerant R410A in transport refrigeration systems.

Author(s) : KWON S. L., BERGE J., NALEY L.

Summary

The European Community ended production of R502 on December 31, 1994. In the United States, production of R502 ended January 1, 1996. To meet the CFC phase-out schedules presented by the world community, Thermo King conducted an extensive test program to numerous alternative refrigerants. Based on a comparative evaluation, Thermo King selected R404A, a near azeotropic mixture of HFC-125, HFC-143a and HFC-134a, as the best replacement for R502. R404A has been classified A1/A1 by ASHRAE and meets all industry safety and performance requirements. This paper reviews the performance requirements of transport refrigeration, the test program developed to measure the performance of alternative refrigerant R404A, and the modifications made to the compressor and other components.
