EER to kW/Ton Calculator

Formula

The formula to convert EER to kW per Ton is:

\[ \text{kW/Ton} = \left(\frac{12}{\text{EER}}\right) \times \left(\frac{\text{Cooling Capacity}}{12000}\right) \]

Where:

\( \text{kW/Ton} \) is the power usage in kilowatts for each ton of cooling capacity.
\( \text{EER} \) is the Energy Efficiency Ratio.
\( \text{Cooling Capacity} \) is the amount of heat removed by the air conditioning system (in BTU/hr).

What is EER?

Energy Efficiency Ratio (EER) is a measure of how efficiently a cooling system operates when the outdoor temperature is at a specific level (usually 95°F). A higher EER rating indicates a more efficient air conditioning system. EER is calculated by dividing the cooling capacity in British Thermal Units (BTU) per hour by the power input in watts.

Example Calculation

Let's assume the following values:

Energy Efficiency Ratio (EER) = 10
Cooling Capacity = 36,000 BTU/hr

Using the formula to convert EER to kW per Ton:

\[ \text{kW/Ton} = \left(\frac{12}{10}\right) \times \left(\frac{36000}{12000}\right) = 1.2 \times 3 = 3.6 \, \text{kW/Ton} \]

The kW per Ton is 3.6 kW/Ton.
