Cooling & Summer Readiness Tool

Cooling Load Calculator

Estimate cooling demand for server rooms, technical rooms and small data-center areas. Convert between kW, BTU/h and tons, check available cooling capacity, and estimate temperature rise during cooling loss.

Room heat load

Cooling inputs

Start with the IT electrical load. Nearly all IT power becomes heat inside the room, so the IT load is the main driver for cooling capacity.

Quick rule 1 kW of heat ≈ 3,412 BTU/h. For IT rooms, electrical IT load is usually the best first estimate because almost all consumed electrical power becomes heat.

Cooling failure helper

Temperature-rise estimate

Estimate how quickly the room air can heat up when cooling is lost. This is a simplified air-volume estimate and does not include wall/floor thermal mass, open doors, leakage, or ventilation.

Summer risk note Cooling loss escalates fast
Important: This temperature-rise estimate can look extreme because it only calculates the air volume. In real rooms, building mass and air leakage slow the rise, but the tool is useful as a risk indicator.

Documentation

Copy planning summary

Copy the result into Jira, ServiceNow, Word, Excel, e-mail, or a project note.

How to use

  1. Enter the total IT equipment power in kW.
  2. Add UPS / power loss percentage and small room loads like people and lighting.
  3. Set a safety margin, commonly 10–30% depending on planning conservatism.
  4. Compare the recommended cooling capacity with available cooling.
  5. Use the temperature-rise helper to understand cooling-failure risk.

Reference conversions

1 kW = 3,412.14 BTU/h. 1 refrigeration ton = 12,000 BTU/h ≈ 3.517 kW. Airflow estimate uses approximately 1.2 kg/m³ air density and 1.005 kJ/kg·K specific heat.
