Summary

The Montreal Protocol is succeeding and now the global environmental challenge is shifting from ozone depletion to global warming. To address this challenge, several new refrigerants have been proposed, and some traditional refrigerants are being re-evaluated, in order to find a balanced solution which satisfies both global environmental demands, and also consumer needs. This study focuses on residential and small commercial unitary systems evaluating proposed new candidates, R1234yf, R32 and R32/R1234yf mixtures as alternatives to current refrigerants with high global warming potentials. These refrigerants were tested extensively in drop-in tests. We conclude that R32 has the potential to provide the best, and the most balanced solution for residential and small commercial unitary applications.
