(1) 3,97 B.T.U./h = 1 kcal/h
(2) The following formula can be used to calculate the air flow rate: Q [mc/h] = 3,1 x P diss [kcal/h] / (t a - t e ) [°C]
P diss is the power expressed in kcal/h dissipated by all the devices installed in the installation environment.
ta= ambient temperature, te=external temperature. In order to take leaks into account, it is necessary to increase
the value obtained by 10%.
The table shows an example of a flow rate with (t a - t e ) =5°C and a rated resistive load (pf=0.9).
(Note: This formula is applicable only if ta>te. If not, the UPS installation requires an air-conditioning system).
(3) The dispersion current of the load is added to that of the UPS on earth wire.
