EXPERIMENTAL INVESTIGATIONS INTO THE TERNARY BLEND HFC22-124-152A AS A SUBSTITUTE IN DOMESTIC REFRIGERATION.

Author(s) : KUIJPERS L. J. M.

Summary

LUBRICANTS FOR HFC REFRIGERANTS ARE DIFFICULT TO DEVELOP. MOREOVER, THERE IS STILL SOME UNCERTAINTY AS TO THE ENERGY EFFICIENCY OF R134A. A TERNARY BLEND, CONSISTING OF R22, R124 AND R152A, HAS BEEN PROPAGATED AS AN ALTERNATIVE REFRIGERANT FOR R12. THE LUBRICANT TO BE APPLIED SHOULD NOT YIELD MAJOR PROBLEMS. THE ENERGY EFFICIENCY SHOULD BE EQUAL OR SLIGHLY BETTER COMPARED TO R12. IN THE STUDY, AN EXPERIMENTAL VERIFICATION OF THE BEHAVIOUR OF THE BLEND IS PERFORMED ON A SERIES OF UPRIGHT FREEZERS. EACH OF THESE FREEZERS IS EQUIPPED WITH A CAPILLARY TUBE OF A DIFFERENT CAPACITY. ONE COMPOSITION OF THE BLEND HAS BEEN INVESTIGATED: ONE THAT IS DETERMINED TO YIELD THE HIGHEST COP, BY THE USE OF A STEADY-STATE CYCLE PROGRAM. THE MAIN CONCLUSION TO BE DRAWN IS THAT A COMPARABLE ENERGY CONSUMPTION CAN BE OBSERVED FOR BOTH R12 AND THE TERNARY BLEND.
