R22 alternative for air conditioners and heat pumps.
Summary
The mixture of R32-R125-R134a (23-25-52 %) is a nonflammable, chlorine-free alternative to R22 that is a close match in capacity and energy efficiency in tests with current design air conditioners and heat pumps. Additional performance improvements are possible through optimization of the expansion device and other system components, including use of liquid line/suction line heat exchange and counterflow evaporators and condensers. A study of mixture vapour leakage followed by recharging with the initial composition demonstrated a maximum loss of 9% capacity after five cycles.
