In HVAC, heating and cooling capacity is sometimes expressed in kilowatts (kW). To properly understand how powerful an air conditioner or a furnace is, we need toconvert kW to BTU(BTU per hour, to be precise). To simply convert kW to BTU, you can use this handy calculator: Basically, ...
The term is defined as the ratio of energy consumption in kW to the rate of heat removal in tons at the rated condition. The lower the kW/ton - the more efficient the system. kW/ton = Pc / Qr (1) where Pc = electrical power consumption (kW) Qr = heat removed (ton) Coeffi...
You have to convert BTU to tons in a number of situations regarding cooling and heating. Examples are numerous and they include anything from evaluating the size of thebest DIY mini splits heretocalculating the air conditioner wire size you need. On top of that, when you usethis calculator f...
