Knowing this information, measure the room where the air conditioning will be installed. The number of people attending the site will also influence the final result. It is recommended to add 600 BTUs (or 800 if there is an effect of sun) each additional user space (the first does not count).
For example, a place without sun incidence of 15 m2 whose use is two people: (600 x 15) + 600 = 9600. That is, you get a device that holds approximately this capability and will be sure of an air conditioner in the right measure.
Factors that affect the final result
Electronics quantity: if there are so many people in the place where the air conditioner is installed, consider purchasing a more powerful model.
Type and quantity of bulbs: incandescent produce more heat to the environment, compared to fluorescent. Identify what model you have and if it warms your room enough to feel heat when you are near the lamps.
Windows and curtains: the windows allow the heat input and the curtain, in turn, minimizes heating.
Region Brazil residence: depending on the local climate, consider purchasing an outfit a little more powerful because of the intense heat.
Every external factor, add 600 BTUs more to the final bill.
