Length x Width x Height = 20 ft x 8 ft x 8 ft = 1280 cubic feet.

2. Estimate Base BTU Requirement

A general rule of thumb is to use 25 BTUs per cubic foot for moderately insulated trucks in moderate climates.

1280 cubic feet x 25 BTU/cubic foot = 32,000 BTUs.

3. Account for Heat Sources

Cooking Equipment

Estimate an additional 5,000 to 10,000 BTUs for the grill and fryer. Let’s use 7,500 BTUs in this example.

Windows and Sunlight

Add approximately 10% to the base BTU calculation to account for windows and solar gain.

32,000 BTUs x 0.10 = 3,200 BTUs.

People

Consider each person adds approximately 600 BTU. With 2 staff members, add 1,200 BTUs.

4. Calculate Total BTU Requirement

Base BTU + Cooking Equipment + Solar Gain + People = Total BTU

32,000 BTUs + 7,500 BTUs + 3,200 BTUs + 1,200 BTUs = 43,900 BTUs.

5. Choose an AC Unit

Based on this calculation, you would need an AC unit with a capacity of at least 43,900 BTUs. Since AC units are often available in standard sizes, you might choose a 48,000 BTU unit.
