LABORATORY TESTING OF A HEAT PUMP SYSTEM USING AN R13B1/R152A REFRIGERANT MIXTURE.

Author(s) : VINEYARD E. A.

Summary

TESTING WAS PERFORMED WITH A NON-AZEOTROPIC MIXTURE OF R13B1/R152A TO DETERMINE ITS ABILITY TO ACHIEVE CAPACITY CONTROL BY ADJUSTING THE COMPOSITION AND INCREASED CAPACITY, RELATIVE TO R22, AT LOW AMBIENT TEMPERATURES. THE SELECTION OF SUCH A MIXTURE COULD IMPROVE THE EFFICIENCY OF A HEAT PUMP BY DECREASING THE CYCLING LOSSES. RESULTS FOR THE MIXTURE SHOW A POTENTIAL CAPACITYMODULATION FROM 3,643 WATTS AT 264.7 K (-8.3 DEG C) TO 2,506 WATTS AT 281.3 K (8.3 DEG C) IN HEATING AND FROM 2,184 WATTS AT 300.8 K (27.8 DEG C) TO 2,693 WATTS AT 308 K (35 DEG C) IN COOLING. AN ANALYSIS OF THE COP FOR THE MIXTURE AND ITS PURE COMPONENTS IS PRESENTED ALONG WITH A COMPARISON AGAINST RESULTS OBTAINED WITH R22.
