Refrigeran t
Compared to common refrigerants, R32 is a
nonpolluting refrigeran t with no harm to the
ozonosphere. The influence upon the green-
house effect is also lower. R32 has got very
good thermodynamic features which lead to a
really high energy e fficiency. The units there
fore need a less filling.

under certain conditions. But the flam-
mability of the refrigerant is very low. It can be
ignited only by fire.
