from the combustible gas or vapor during the operation is reduced to minimum.
6. Requirements for the total weight of filled refrigerant and the area of a room to be equipped with an air
conditioner (are shown as in the following Tables GG.1 and GG.2)
The maximum charge and the required minimum floor area
