## Formula

Cooling kW = heat load ÷ COP. Energy = cooling kW × hours.

- Methodology: coefficient of performance relationship from ASHRAE Handbook — Fundamentals.
- COP varies with outdoor conditions and load; use a seasonal figure for annual estimates.
- No COP is assumed.
- Cooling kW = heat load ÷ COP. Energy = cooling kW × hours.
- Inputs used: Heat to remove (usually IT load), Cooling system COP (your plant's measured or rated figure), Hours in the period.

## Inputs

- Heat to remove (usually IT load)
- Cooling system COP (your plant's measured or rated figure)
- Hours in the period

## Worked example: A year of cooling

160 kW of heat, plant COP 4, 8,760 hours.
1. 160 ÷ 4 = 40 kW.
2. 40 × 8,760 = 350,400 kWh.

## Common questions

### Where do I get COP?

From metered plant data (heat removed ÷ electricity used) or the manufacturer's seasonal rating. Check the formula, example, and limitations on this page before using the result for a real data centers decision.

### Is there a target or industry average built in?

No. Results depend on climate, design, load and measurement point, so none is shown. Compare against your own history.

### Does free cooling count?

Yes — it raises the seasonal COP. Enter the effective figure.

### How do I use the Cooling Energy Calculator?

Enter the required values for Heat to remove (usually IT load), Cooling system COP (your plant's measured or rated figure), Hours in the period. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Cooling Energy Calculator use?

Cooling kW = heat load ÷ COP. Energy = cooling kW × hours. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Cooling Energy Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Single average COP.
- Fans and pumps only included if they are in your COP.
- Results are estimates built only from the figures you enter. No electricity, fuel or gas price, equipment efficiency or benchmark is built in — tariffs vary by supplier, region and time, and equipment data must come from the manufacturer. Designs and installations must be checked by a qualified professional.
- The result depends on the values you enter for this cooling energy calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
