I am too seeking right answer, but I know that the calculations above are incorrect. We have to consider the heat generated by BTSs and not the power consumed by BTSs. We have to take into account the heat generated/ rate of heat generation in Watts by all the equipment inside the shelter. There are 48V SMPS, Battery sets, BTSs, Microwave equipment, lights and assume 2 persons working. Heat generated by the SMPS equals input power minus the output power (i.e. loss of energy in terms of heat). But for rest items need the information on heat generated. Then only we can arrive at correct air conditioner capacity requirement.
