1 btu is the energy needed to heat 1 pound of water by 1 fahrenheit.
Btu to square feet cooling.
A british thermal unit or btu is a unit of measurement of energy.
700 1000 square feet 18000 btu per hour 12.
If you want to properly cool down a 300 square foot area or room you need a 6 000 btu air conditioner.
In order to size your mini split correctly you will need to know the square footage of the room and check it against our table.
To size your mini split air conditioner the most important thing you need to know is the square footage of the room you re looking to cool and or heat.
This is done by calculating your square footage.
The most common window air conditioning units come in cooling capacities ranging from 5 000 to 12 000 btu.
To figure out what size air conditioner you require you first need to determine the amount of btus you require.
To learn how to adjust btu per square foot for special conditions scroll down.
However volume is a more accurate measurement than area for determining btu usage because ceiling height is factored into the equation.
How to find how many btus your furnace should be.
1 btu is the equivalent of 1 055 joules or 293 watts.
Btus stand for british thermal units and refer to the amount of energy your air conditioner is using per hour.
1 horsepower 745 69 watts 7.
For example if you re trying to heat or cool 1 000 square feet you would multiply 1 000 by 20 and get 20 000 btus per hour.
According to the us department of energy directive the most appropriate size of an air conditioner would be 2 880 btu unit.
1 btu hr 0 293 watts 8.
Obviously the problem arises when you have a very small 12 12 room for example.
1 square meter 10 76 square feet 5.
Each three dimensional cubic square foot of space will require a certain amount of btu usage to cool heat accordingly.
The smaller the volume the fewer btus are required to cool or heat.
Air conditioners cool your home and sizing the air conditioner to the room size is essential for proper efficiency and cooling capacity.
450 550 square feet 12000 btu per hour 11.
A simple formula to determine your heating needs is.
Desired temperature change x cubic feet of space x 133 btus needed per hour.
Once you have the total square footage just multiply that number by 20 to find how many btus per hour you d need to heat or cool the space.
For example a 300 square foot room typically requires 7 000 btus to maintain a comfortable temperature while a 1 000 square foot room requires 18 000 btus.
1 ton 11956 14 btu per hour 9.
What factors can impact your heating needs.
1400 1500 square feet 24000 btu per hour.
Air conditioners are rated in btu s and the btu rating determines the cooling capacity in the square footage of the living area to be cooled.
We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h.
Air conditioners are sized by the number of btus they put out.
1 watt 3 412 btu per hour 6.
