example:
ups-60KVA (as per catalog it produces 12283.2 btu/hr, so the room needs more than 1TR for cooling, i used wall type AC)
transformer-75KVA (from my calculation at least 400 cfm is need to remove the heat produce by transformer, the exhaust grilles is placed right above the transformer)
thanks

You need to account for humidification/dehumidification needs.
If your supply is too cold, it might lead to electrostatic discharge. Be careful when setting the supply temperature.
According to the data you gave us, you also need to increase the cooling load to cover the UPS and the transformer.

1) Maintaining suitable room conditions for UPS batteries. In Australia its common for split type DX systems to serve these room. Allowance for 5% of the full battery load is a common conservative figure for preliminary sizing. Batteries are often rated for certain temperatures, in cooler climates its a common oversight to provide cooling only type systems and ignore the fact that batteries take longer to charge when in cold environments.
2) Ventilation of UPS batteries - Many UPS batteries are sealed lead acid types. There are ventilation standards which require minimum ventilation for these types of rooms. Refer to local standards for guidance.
