What Btu Is Required To Cool A Room

A british thermal unit or btu is a unit of measurement of energy.

What btu is required to cool a room.

1 btu is the equivalent of 1 055 joules or 293 watts. We often refer to the british thermal unit as a btu but the rating is actually the btus per hour or btu h. If the room or house you are cooling is heavily shaded you may need 10 percent fewer btus to cool it. If the house or room is very sunny however add 10 percent more btus.

For reference btu is simply a designation of cooling power the higher the btu the more powerful the cooling. The following is a rough estimation of the cooling capacity a cooling system would need to effectively cool a room house based only on the square footage of the room house provided by energystar gov. If a room is regularly occupied by more than two persons we need to adjust the recommended btu per hour capacity of the air conditioner by about 600 btu hr for each additional person. Obviously the problem arises when you have a very small 12 12 room for example.

The result is the btu requirement for cooling a room with the details you entered is of 12 980 btu h this is approximately 3 804 kw 18 mar 2015. Simply measure the length and width of a room and figure the square footage. How to calculate how many btu s you need. Finally we also need to consider the location of the room and its type whether it s a bedroom or a kitchen etc.

What factors can impact your heating needs. Desired temperature change x cubic feet of space x 133 btus needed per hour. The smaller the volume the fewer btus are required to cool or heat. Let s say it is a 10 foot by 15 foot room.

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. Using the sizing chart to calculate the appropriate btu rating needed to cool that area of the home it s an easy selection choice from there. Multiply the two together to get 150 square foot room. Calculate how many btus you need to heat a room or even a house with a wood burning pellet or gas fireplace insert or stove.

A simple formula to determine your heating needs is. This btu calculator will determine what hearth product size is required with only a few steps and information such as square footage sq ft. 1 btu is the energy needed to heat 1 pound of water by 1 fahrenheit. For a room with a length of 14ft width of 13ft used as a kitchen by 5 persons plus it is placed in a sunny space.
