What would be the heat transfer rate of a 30 ton refrigeration system?

To determine the heat transfer rate of a refrigeration system, a standard conversion factor is often used: one ton of refrigeration is equivalent to the ability to remove heat at a rate of 12,000 BTUs per hour. Therefore, for a 30-ton refrigeration system, the heat transfer rate can be calculated by multiplying the number of tons by the conversion factor.

In this case, the calculation would be:

30 tons x 12,000 BTUs/ton = 360,000 BTUs per hour.

This means that a 30-ton refrigeration system can remove heat at a rate of 360,000 BTUs per hour, making this the correct answer. Understanding this conversion is crucial for operating engineers, as it informs not only the capacity and performance of refrigeration systems but also aids in designing efficient HVAC systems and performing proper load calculations.
