Using 1 refrigeration ton = 12,000 Btu/h, how many tons of cooling correspond to a scheduled capacity of 180,000 Btu/h?
Correct Answer
D) 15 tons
180,000 Btu/h ÷ 12,000 Btu/h per refrigeration ton = 15 tons of cooling. This is a heat-removal rate, not equipment weight or a complete sizing calculation.
Why This Is the Correct Answer
180,000 Btu/h ÷ 12,000 Btu/h per refrigeration ton = 15 tons of cooling. This is a heat-removal rate, not equipment weight or a complete sizing calculation.
