Use of a ternary blend in existing domestic CFC-12 appliances.

Author(s) : SNITKJAER L., EGGERT F. K.

Summary

Waiting for common use of R134a, there will still be a need for servicing existing domestic R12 refrigerators and freezers. To satisfy this need the drop-in substitute must be fully compatible. The ternary blend 52% R22/ 15% R152a/ 33% R124 is evaluated and compared with R12 on the basis of available thermodynamic properties, laboratory and application tests. The evaluation criteria are capacity, COP, start and stall characteristics. The influence of inherent differences between test conditions and thermodynamics of the two refrigerants is discussed.
