One standard commercial ton of refrigeration is equivalent to_________________?
Show answer Hide answer
Answer: A. 50 kcal/min
Explanation
One standard commercial ton of refrigeration is equivalent to fifty kilocalories per minute. This cooling capacity equals the heat removal rate needed to melt one ton of ice daily. Refrigeration tonnage provides a standard unit for sizing commercial cooling equipment. One refrigeration ton equals twelve thousand BTU per hour or two hundred BTU per minute. Melting one ton of ice over twenty-four hours absorbs substantial latent heat energy. Metric refrigeration units often use kilocalories per hour or kilowatt cooling capacities.
HVAC contractors calculate building cooling loads in standard tons of refrigeration. Air conditioning chillers are rated commercially by their total refrigeration tonnage capacity. Proper tonnage sizing ensures buildings maintain comfortable indoor temperatures during peak summer. Fifty kilocalories per hour is far too small and represents incorrect unit conversion math. Eighty kilocalories per minute overestimates standard ice-melting latent heat ratings. Eighty kilocalories per hour does not match standard commercial refrigeration tonnage definitions.
