About these units
Short background on the units used in this conversion.
Ton (Refrigeration) (TR)
One ton of refrigeration removes heat at 12,000 BTU/h (IT) — about 3,516.85 watts of cooling power.
Tons of refrigeration rate commercial HVAC chillers, walk-in coolers, and central air systems.
Frequently asked questions
