How many BTU/h are there in one ton of cooling?

One ton of cooling is defined as the capacity to remove heat at a rate of 12,000 British Thermal Units per hour (BTU/h). This measurement comes from the historical context of refrigeration, where one ton of ice can absorb heat as it melts, amounting to 12,000 BTUs over a 24-hour period. This standard remains widely accepted in the HVAC industry and is essential for understanding cooling load calculations.

In commercial drying and environmental control, knowing the tonnage of cooling is crucial when setting up dehumidification and drying equipment, as it helps professionals determine the right size and capacity needed to efficiently manage moisture levels and facilitate drying processes.
