Aircon btu complete guide

A British thermal unit (BTU) is a standard unit of power that is used in the United States and sometimes in the U.K. It shows the quantity of thermal power essential to increase the temperature of 1 pound of clean liquid water by one degree Fahrenheit temperature at which water has its utmost density (39 degrees Fahrenheit). The Btu is a measure in the famous English system of units. Other countries use the Joule, the unit of power in the international system of Units. An aircon BTU is equivalent to about 1055 joules.

What is btu

The Btu is generally used as a quantitative specification of the power-transferring or power-producing capability of cooling and heating system such as ovens, furnaces, air conditioners, and refrigerators. The warm output of computer equipment is generally specified so that it can be considered when planning the size of climate control systems in buildings. Computer gadget heat output is expressed in Btus per hour. 3.7 per hour is equal to one watt of heat dissipation.

BTU in general household items

You will most generally find it to used to calculate BTU/hr (BTUs per hour) in cooling and heating machines but it is also used to measure the value of many other items.

BTU is used as a unit of classification in:

  • Solar hot water heating
  • Heaters
  • Air conditioners
  • Heating fuel
  • Gas fire pits
  • Cooking devices

Too much of a good thing

A top number of BTUs is not forever the answer. Using an aircon for living room level higher than required can cause the unit to chill fast, cycle off, and then, to maintain your wanted temperature, have to cycle on again soon after.

If the room is occupied by more than 2 people on a regular basis, six-hundred extra BTUs are supposed to be included for each extra person. Also, the condition should be the same if the aircon system is going to be located in the kitchen. In this case, the capability should be increased to 4,000 BTUs. The right place where you are going to install the unit is equally of huge significance.  For example, if you are going to install it at the corner of the room, it is best to look for a unit size that will be capable to distribute the air in the correct direction.
