Work out data centre cooling load instantly with clear inputs, formula shown and shareable results.
Essentially all electrical energy entering IT equipment leaves as heat, so cooling capacity must match the full IT load plus lighting and losses, with margin. The coefficient of performance is how much heat is moved per unit of electricity consumed, so a COP of 3.5 means cooling adds roughly 29 percent to the facility's electrical draw.
Cooling load
heat = IT load + other loads; capacity = heat x (1 + margin); cooling electrical draw = capacity / COP; 1 ton = 3.517 kW
Because computers do no mechanical work. Every watt consumed is converted to heat, which is why the two figures are treated as identical in facility design.
Higher supply air temperatures, hot and cold aisle containment, free cooling using outside air, and liquid cooling for high-density racks.
