In common practice, how many BTUs is equivalent to one ton of refrigeration?

• A. 100 BTU
• B. 200 BTU
• C. 300 BTU
• D. 400 BTU

Answer: (B)

One ton of refrigeration is commonly defined as the amount of heat that must be absorbed to freeze one ton (2,000 pounds) of water at 32°F in 24 hours. This process requires a total absorption of 288,000 BTUs over that period. When breaking it down, this translates to 12,000 BTUs per hour since there are 24 hours in a day. This amount signifies the cooling capacity or cooling effect produced by one ton of refrigeration. In practical terms, the relationship between tons of refrigeration and BTUs is widely accepted in the HVAC industry, where one ton of refrigeration is equated to approximately 12,000 BTUs per hour. This fundamental conversion is crucial for understanding how refrigeration systems operate, especially in sizing and performance calculations. The answer of 200 BTUs would not align with the established understanding within the HVAC field about tonnage and its equivalent BTU measurement, thus reinforcing the necessity to refer to standard definitions to ensure accuracy.
