A refrigeration system rated at 5 tons can remove how many BTUs per hour?

To determine how many BTUs per hour a refrigeration system rated at 5 tons can remove, it is important to understand the conversion between tons and BTUs. One ton of refrigeration is defined as the ability to remove 12,000 BTUs of heat per hour. Therefore, to find the total capacity in BTUs for a system rated at 5 tons, you can multiply the number of tons by the number of BTUs per ton.

In this case, you multiply 5 tons by 12,000 BTUs per ton:

5 tons × 12,000 BTUs/ton = 60,000 BTUs per hour.

This calculation shows that a 5-ton refrigeration system can effectively remove 60,000 BTUs of heat from the environment per hour, which provides a precise understanding of its cooling capacity. The correct answer aligns with this calculation, illustrating the fundamental principle in refrigeration where tonnage is directly related to BTU capacity.
