About the Btu/hour

Facts & Uses

  • Standard power rating in HVAC (heating, ventilation, air conditioning) systems.
  • Air conditioners and furnaces are often rated in Btu/h or tons of refrigeration (1 ton = 12,000 Btu/h).
  • Useful for comparing cooling capacities or fuel efficiencies.

Curiosities

  • 1 Btu/h = 0.293071 W — a 12,000 Btu/h air conditioner is roughly 3.52 kW.
  • MBH (1000 Btu/h) is a common shorthand in U.S. equipment specs.

About the Ton Of Refrigeration

Facts & Uses

  • Industry-standard cooling power unit for refrigeration and air conditioning.
  • 1 TR = 12,000 Btu/h = 3.5168525 kW.
  • Used globally to rate chillers, cooling towers, and A/C systems.

Curiosities

  • Originates from the heat needed to freeze one short ton (2000 lb) of water in 24 hours.
  • 1 ton of cooling ≈ 3.5 kW, roughly equal to a medium home A/C system.

Frequently Asked Questions

How many tons of refrigeration are in one Btu/hour?
