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:
12,000.00 Btu IT /h 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.
Air conditioning can be achieved using a mechanical 'air conditioner' or by other methods, including passive cooling and ventilative cooling. [ 2 ] [ 3 ] Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC) . [ 4 ]
All modern air conditioning systems, even small window package units, are equipped with internal air filters. [citation needed] These are generally of a lightweight gauze-like material, and must be replaced or washed as conditions warrant. For example, a building in a high dust environment, or a home with furry pets, will need to have the ...
Lowe's Market traces its history to E.M. "Bud" Lowe who sold candy and sundries from the back of a truck in Littlefield, Texas in the 1940s. [2] In 1964, Bud Lowe opened the first Lowe's Market, a small grocery store, in Olton, Texas. The company began the process of gradual expansion into small and medium-sized towns in Texas and New Mexico.
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]
One BTU is the energy required to raise one pound of water one degree Fahrenheit, but the many different types of BTU are based on different interpretations of this “definition”. In the United States the power of HVAC systems (the rate of cooling and dehumidifying or heating) is sometimes expressed in BTU/hour instead of watts.
