Performance and dynamic flammability of R32/134a mixtures in water-to-water heat pumps.

Thermodynamic properties and refrigerating performance for the alternative R32/134a mixtures in waterto-water heat pumps have been analyzed. Also, its dynamic model and flammability during the leakage process have been investigated. The results show that R32/134a (30/70) is a good alternative for waterto-water heat pumps. But the possibility of burning and explosive accidents during the leakage process cannot be excluded. [ABSTRACT FROM AUTHOR]
