2. Ton of refrigeration - Wikipedia

   en.wikipedia.org/wiki/Ton_of_refrigeration

   2,593.90 ft⋅lbf/s A ton of refrigeration ( TR or TOR ), also called a refrigeration ton ( RT ), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.

3. Seasonal energy efficiency ratio - Wikipedia

   en.wikipedia.org/wiki/Seasonal_energy_efficiency...

   Air-conditioner sizes are often given as "tons" of cooling, where 1 ton of cooling equals 12,000 BTU/h (3.5 kW). 1 ton of cooling equals the amount of power that needs to be applied continuously over a 24-hour period to melt 1 ton of ice. The annual cost of electric energy consumed by an air conditioner may be calculated as follows:

4. Cooling capacity - Wikipedia

   en.wikipedia.org/wiki/Cooling_capacity

   The SI unit is watt (W). Another unit common in non-metric regions or sectors is the ton of refrigeration, which describes the amount of water at freezing temperature that can be frozen in 24 hours, equivalent to 3.5 kW or 12,000 BTU/h. [1] [2] [3]

5. Coefficient of performance - Wikipedia

   en.wikipedia.org/wiki/Coefficient_of_performance

   The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [ 1 ] [ 2 ] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs.

6. British thermal unit - Wikipedia

   en.wikipedia.org/wiki/British_thermal_unit

   It is the rate of heat transfer needed to freeze 1 short ton (907 kg) of water into ice in 24 hours. In the United States and Canada, the R-value that describes the performance of thermal insulation is typically quoted in square foot degree Fahrenheit hours per British thermal unit (ft 2 ⋅°F⋅h/Btu). For one square foot of the insulation ...

7. Orders of magnitude (energy) - Wikipedia
