The maximun charge in a room shall be in accordance with the following:
m = 2,5 x (LFL)
max
or the required minumum floor area
M(kg) shall be in accordance with following:
A = (M/(2,5 x (LFL)
min
Where.
m
is the allowable maximum charge in a room, in kg;
max
M is the refrigerant charge amount in appliance, in kg;
A
is the required minimum room area, in m ;
min
A
is the room area, in m ;
LFL
is the lower flammable limit, in kg/m ;
h
is the release height, the vertical distance in metres from the floor to the point of
0
release when the appliance is installed;
h h h
= ( inst+ rel) or 0,6 m whichever is higher
0
h
rel is the release offset in metres from the bottom of the appliance to the point of
release
h
inst is the installed height in metres of the unit
Reference installed heights are given below:
0.0 m for portable and floor mounted;
1.0m for window mounted;
1.8m for wall mounted;
2.2m for ceiling mounted;
If the minimum installed height given by the manufacturer is higher than the reference
installed height, then in addition A
be given by the manufacturer. An appliance may have multiple reference installed heights.
In this case, A and m
min
installed heights.
For appliances serving one or more rooms with an air duct system, the lowest opening of the
duct connection to each conditioned space or any opening of the indoor unit greater than
2
5 cm , at the lowest position to the space, shall be used for h
than 0,6 m. A shall be calculated as a function of the opening heights of the duct to the
min
spaces and the refrigerant charge for the spaces where leaked refrigerant may flow to,
considering where the unit is located. All spaces shall have a floor area more than A
