ShareR152a versus R134a in domestic refrigerator-freezer: energy advantage or energy penalty!
Author(s) : SANVORDENKER K. S.
Summary
R152a has been predicted to offer a degree of energy advantage over R134a as the working fluid. The Association of Home Appliance Manufacturers (AHAM) consortium summarizing laboratory calorimeter data showed an energy penalty of approximately 8% for R134a over R152a. The author questioned the validity of the AHAM data, and presented calorimeter results showing no energy advantage for R152a over R134a; and in the process identified errors in the thermodynamic data on R152a as printed in the ASHRAE Handbook. Data have been determined on five additional high efficiency compressors using R12, R134a and R152a. These data show that R152a not only offers no energy advantage but on the contrary, is, in certain conditions, worse.
