Calculation for needed cooling capacity in UDH DCO battery Room

Estimation of total heat gain = 18149 BTU/hr

CFM needed:

18149/(1.1*17) = 970.5 CFM

Estimation of total heat gain based on temperature measurements

1.1*475*19 = 9930 BTU/hr

The idea is that 970.5 – 475 = 500 CFM need to be added to the duct into the battery room

So this means 500 CFM need to be added to the indoor unit of the DC room. Also cooling capacity of

1.1*500*17 = 9350 BTU/hr need to be added to the capacity of the indoor unit.
