Question 1 of 27070

An air conditioning system, required to remove from 33,000 to 35,000 BTU per hour, should have a minimum capacity of what tonnage?

🔍 Key Concepts

• Relationship between BTU per hour and refrigeration tons (1 refrigeration ton = 12,000 BTU/hr) • How to convert a BTU/hr load into tons of refrigeration using division • Why you might round up the capacity rather than down when sizing equipment

💭 Think About

• First, convert both 33,000 BTU/hr and 35,000 BTU/hr into tons. What number do you get when you divide by 12,000? • Think about which of the multiple-choice options is at least as large as the maximum load you calculated, not smaller. • Ask yourself: In practice, should you choose an air conditioning capacity that is slightly under, exactly equal to, or slightly above the calculated maximum BTU/hr load?

✅ Before You Answer

• Verify that you are using 1 ton = 12,000 BTU/hr in your calculation. • Check that the tonnage you choose is not less than what is required for 35,000 BTU/hr. • Confirm that you round in the correct direction for safety and performance (avoid undersizing the system).
