To realize the function of the air conditioner unit, a special refrigerant circulates in the system.

The used refrigerant is the uoride R32, which is specially cleaned. The refrigerant is
ammable and inodorous. Furthermore, it can leads to explosion under certain condition.
But the ammability of the refrigerant is very low. It can be ignited only by re.

Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the
ozonosphere. The inuence upon the greenhouse effect is also lower. R32 has got very
good thermodynamic features which lead to a really high energy efciency. The units
therefore need a less lling.
