Where LFL is the gas limit in kg / m3. For the R32 LFL is 0.306 kg / m3 -
For appliances with loads between m1 and m2 the maximum load in a room must be
according to the following formula: mmax = 2.5 x (LFL)
(5/4)
x hº x

Where the minimum area
Amin
to install the appliance with the gas load M (kg) should
be as follows
Amin
= M / 2.5 x ((LFL)
(5/4)
x hº ))

Mmax is ka maximum load in the room, per kg
M is the quantity of gas charged in the appliance, in kg
Amin
is the minimum area of the room in m2
A is the area of the room in m2
