6-1 Calculation of required number of valves
The following formula determines number of valves needed for a given case.
=
Number of valves
V = Volume of the room in m³
T = Time variation in min. for 1 °C
t = Room température in C° - 273 and 0,47 are constant values.
Example for V = 10 000 T = 3 minutes for 1 °C t = -30 °C
0,47x10000
Number fo valves :
3(273-30)
If the data used for calculation are exactly observed, the 7 valves will ensure that an evenly distributed
pressure of 200 PA (20 kg/m²) is not exceeded.
