Cooling Capacity Calculator

How to Use This Calculator

1. Enter the electrical power consumption of your air conditioning unit in kilowatts (kW). This value is typically found on the unit's specifications or energy label.
2. Set the COP (Coefficient of Performance) value. For most residential systems, a value between 2.5 and 4.0 is appropriate. The default value is 3.0.
3. Click the "Calculate" button to compute the cooling capacity in BTU/h.
4. The calculator will display the electrical power, COP, and resulting cooling capacity.

Understanding Cooling Capacity

Cooling capacity is measured in British Thermal Units per hour (BTU/h), which represents the amount of heat the AC system can remove from a space per hour. A higher BTU/h value indicates greater cooling power.

Formula Explanation

The calculator uses the following formula:

Cooling Capacity (BTU/h) = Electrical Power (kW) × COP × 3412

This formula converts electrical power from kilowatts to BTU/h using the conversion factor of 3412 (1 kW = 3412 BTU/h) and accounts for the energy efficiency of the AC system through the COP value.

Practical Applications

This calculator can help you:

• Estimate the cooling capacity of an AC unit before purchase
• Verify if your current AC system is adequate for your space
• Compare different AC models based on their cooling capacity
