(1) 3.97 B.T.U./h = 1 kcal/h
(2) Use the following formula to calculate air flow: Q [mc/h] = 3.1 x Pdiss [kcal/h] / (ta - te) [°C]
Pdiss is power dissipation expressed in kcal/h in the installation site for all installed equipment.
ta= room temperature, te=external temperature. Increase the value derived by 10% to account for losses.
An example of flow is shown in the table, with (ta - te)=5°C and with nominal resistive load (pf=0.9).
(Note: This formula is applicable if ta>te; otherwise, installation requires an air conditioner).
(3) The load dispersion current is added to that of the UPS on the ground protection conductor.
