Cooling Capacity Selector
*Air conditioners are sized by cooling capacity in BTU's
per hour. To estimate the optimum capacity for any room,
first calculate the size of the area to be conditioned
by multiplying its width times its legnth, measured in
feet.
*Then select the cooling capacity needed using the table
below, The BTU's associated with the square footage will
give an approximate optimum for the space.
*Cooling capacities are based on rooms occupied by two
people and having average insulation, number of windows,
and sun exposure. To adapt the table for varying conditions,
modify the capacity figures with the data shown to the
right -> |

Cooling Capacity Selector *Reduce capacity by 10% if area is heavily shaded.
*Increase capacity by 10% for very sunny areas.
*Add 600 btu/hr for each additional person if area is occupied routinely by more than two people.
*Add 4000 btu/hr if area to be cooled is an average size kitchen.
*Add 1000 btu/hr for every 15 sq/ft of glass exposed to sun.
*Add 3414 btu/hr for every 1000 watts of electronic equipment. |
