ShareDrop-in testing of R32 blends as R22 alternatives in a split-system air conditioner.
Author(s) : KONDEPUDI S. N.
Summary
The paper presents results obtained from an experimental program where R32-R134a and R32-R152a blends were tested in a two-ton split-system air conditioner. Five different refrigerant blends were tested against a set of R22 baseline tests for comparison. While the tests showed that, compared to R22, the R32-R134a blends performed to within 2% of efficiency with comparable capacity, it is expected that with proper system optimization for the new refrigerant blends, such as optimal charge, temperature glide, superheat-subcooling, and expansion device, performance levels better than those of R22 should be possible.
