Server Room Cooling Calculator
Cooling for an IT room: every watt of IT load is a watt of heat, plus room gains.
IT load is 24/7/365 โ comfort splits die young here. Spec units rated for low-ambient (winter head-pressure control) and lay them out N+1.
Formula
Server Room Cooling Calculator is a free server room cooling for HVAC designers, technicians and energy auditors โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Server Room Cooling Calculator
Cooling for an IT room: every watt of IT load is a watt of heat, plus room gains. The calculation implements Q = ITร(1+UPS%) + envelope + lighting; units in 2-ton steps + N+1 (ASHRAE TC 9.9 โ datacom equipment thermal guidelines). IT load is 24/7/365 โ comfort splits die young here. Spec units rated for low-ambient (winter head-pressure control) and lay them out N+1.
