EXPERIMENTAL RESEARCH OF HIGH-TEMPERATURE COMPOSITION CHANGEABLE CIRCUIT USING ALTERNATIVE MIXTURES.

[In Japanese. / En japonais.]

Type of article: Article

Summary

FOUR KINDS OF NON-AZEOTROPIC MIXTURES R22-R134A, R22-142B, R22-R152A AND R22-R123, WERE EVALUATED IN ORDER TO REALIZE HIGHER CONDENSING TEMPERATURE THAN THAT USING R22 AT HIGH TEMPERATURE OPERATION, AND LARGER HEATING CAPACITY THAN THAT USING R22-R114 AT NORMAL TEMPERATURE OPERATION. ISOTHERMAL VAPOUR-LIQUID EQUILIBRIUM FOR SOME OF THESE MIXTURES WAS MEASURED BY THE STATIC METHOD. AS A RESULT, THE COMPOSITION CHANGEABLE HIGH-TEMPERATURE HEAT PUMP INDICATED THE MOST EFFECTIVE CHARACTERISTICS WHEN USING R22-R142B AS THE REFRIGERANT.
