What is a BTU?
1 BTU = 1 055.05585 Joules
The British thermal unit (BTU or Btu) is a unit of energy used in the power, steam generation, heating and air conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule (J), though it may be used as a measure of agricultural energy production (BTU/kg). It is still used 'unofficially' in metric English-speaking countries (such as Canada, the United Kingdom, and sometimes in New Zealand), and remains the standard unit of classification for air conditioning units manufactured and sold in many non-English-speaking metric countries.
In North America, the term "BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU 'per hour' (BTU/h, that is, BTU divided by hour) is understood, though this is often confusingly abbreviated to just "BTU".
The unit MBTU was defined as one thousand BTU presumably from the Roman numeral system where "M" stands for one thousand (1,000). This is easily confused with the SI mega (M) prefix, which adds a factor of one million (1,000,000). To avoid confusion many companies and engineers use MMBTU to represent one million BTU. Alternatively a therm is used representing 100,000 or 105 BTU, and a quad as 1015 BTU.
R-410A, sold under the trademarked names Puron, Genetron R410A, and AZ-20, is a near-azeotropic mixture of difluoromethane (CH2F2, called R-32) and pentafluoroethane (C2HF5, called R-125) which is used as a refrigerant in air conditioning applications.
Unlike many haloalkane refrigerants it does not contribute to ozone depletion, and is therefore becoming more widely used as ozone-depleting refrigerants like R-22 are phased out. However, it has a high global warming potential of 1725 (1725 times the effect of carbon dioxide), similar to that of R-22.
While R-410A was invented and patented by Allied Signal (now Honeywell) and Honeywell continues to be the leader in 410A capacity and sales, other producers around the world have been licensed to manufacture and sell the product.R-410A was successfully commercialized in the air conditioning segment by a combined effort of three companies. Carrier Corporation, Emerson Climate Technologies, Inc. with Copeland Scroll Compressors (a division of Emerson Electric Company), and Allied Signal worked together in developing the refrigerant for practical use in air conditioners in the US. R-410A is also the preferred refrigerant for use in residential and commercial air conditioners in Japan and Europe, replacing R-22.
Carrier Corporation was the first company to introduce a R-410A-based residential AC unit in the marketplace in 1996.[citation needed] Carrier holds the trademark Puron and is still the leading supplier of energy efficient R410A AC systems for residential, commercial and chiller applications in the US today.R-410A is incompatible with R-22 refrigerant.
