How many BTUs are removed in a 30 ton cooling system per hour?

To determine how many BTUs are removed by a 30 ton cooling system in one hour, it's important to understand the conversion between tons of cooling capacity and BTUs. In air conditioning, one ton is equivalent to the ability to remove 12,000 BTUs of heat per hour.

Therefore, to find the total BTUs for a 30 ton system, you multiply the number of tons by the BTUs per ton. Specifically, for a 30 ton cooling system, the calculation would be:

30 tons × 12,000 BTUs/ton = 360,000 BTUs.

This means a 30 ton cooling system is capable of removing 360,000 BTUs of heat from an environment every hour. This aligns perfectly with the correct answer, emphasizing the importance of understanding the relationship between tonnage and BTUs in HVAC systems.
