The higher the BTU requirement, the more powerful the refrigeration unit needs to be.

BTU Calculation Formula:BTU/hr = (Volume in cubic feet) x (Temperature Difference Factor) x (Safety Factor)

• Volume in cubic feet: This is the value you calculated in the previous step.
• Temperature Difference Factor: This considers the difference between the desired internal temperature and the ambient temperature (the temperature outside the refrigerated space). The greater the temperature difference, the higher the cooling load. A typical temperature difference factor for a standard cooler operating at 38°F (3.3°C) in an 80°F (26.7°C) environment is 1.25.
• Safety Factor: This accounts for factors like door openings, the introduction of warm products, and heat generated by equipment inside the refrigerated space. A safety factor of 1.25 to 1.5 is often used.

Example:

Let’s say a restaurant needs to calculate the BTU requirements for a walk-in cooler that is 10 feet long, 8 feet wide, and 8 feet high, with an ambient temperature of 85°F (29.4°C) and a desired internal temperature of 38°F (3.3°C). The restaurant anticipates moderate door openings and warm food introductions.

1. Volume: 10 ft x 8 ft x 8 ft = 640 cubic feet
2. Temperature Difference: 85°F – 38°F = 47°F
3. Temperature Difference Factor: Assume a factor of 1.25.
4. Safety Factor: Use a safety factor of 1.3.
5. BTU Calculation: 640 cu ft x 1.25 x 1.3 = 1040 BTU/hr

Therefore, the restaurant needs a refrigeration unit with a capacity of at least 1040 BTU/hr, accounting for potential heat gain and usage.
