4. Calculation of Air Conditioning capacity

The calculation of the capacity of the air conditioner is a crucial aspect that needs to be considered when installing an air conditioner. Air conditioning unit capacity is measured in BTUs (British Thermal Units) and determines the amount of heat the unit can remove from a room in one hour. The correct choice of air conditioning capacity will ensure that the device works efficiently and effectively, providing the desired level of comfort.

To calculate the capacity of the air conditioner, there are several factors to be taken into account. These include the size of the room, the number of people who normally occupy the room, the number of windows and doors, the number of electronic devices in the room, the orientation of the room with respect to the sun, and the amount of insulation in the room.

The first step in calculating the capacity of the air conditioner is to determine the size of the room. This is done by multiplying the length, width and height of the room to obtain the volume in cubic meters. For example, if the room measures 5 meters long, 4 meters wide and 3 meters high, the volume would be 60 cubic meters.

Next, you need to consider the number of people who typically occupy the room. Each person in a room contributes about 600 BTUs of heat. So if the room is normally occupied by two people, this would add 1200 BTUs to the required air conditioning capacity.

The number of windows and doors in the room also affects the required air conditioning capacity. Windows and doors can let in heat, especially if they face the sun. Therefore, for each window or door in the room, you need to add about 1000 BTUs to the required air conditioning capacity.

The amount of electronic devices in the environment should also be taken into account. Electronic devices such as computers and televisions generate heat when in use. Therefore, for every electronic device in the room, you need to add about 400 BTUs to the required air conditioning capacity.

The orientation of the room in relation to the sun also affects the required capacity of the air conditioner. If the room faces the sun, it will be necessary to add about 10% to the required capacity of the air conditioner. If the room faces the shade, it will be necessary to subtract about 10% of the required air conditioning capacity.

Finally, the amount of isolation in the environment must also be taken into account. A well-insulated room requires less air conditioning capacity than a poorly insulated room. Therefore, if the environment is well insulated, it will be necessary to subtract about 10% of the required air conditioning capacity. If the room is poorly insulated, it will be necessary to add about 20% to the required air conditioning capacity.

After considering all these factors, it is possible to calculate the required capacity of the air conditioner. For example, if the room volume is 60 cubic meters, the room normally occupied by two people, with two windows, one electronic device, facing the sun and poorly insulated, the required capacity of the air conditioner would be about 8000 BTUs .

It is important to remember that the air conditioning capacity calculation is only an estimate. For a more accurate assessment, it is recommended to consult an air conditioning professional. Also, it's always best to choose an air conditioner with a little more capacity than necessary to ensure that the unit can handle temperature variations and other unforeseen conditions.

In summary, calculating the capacity of the air conditioner is an important step in the installation of the air conditioner. By considering factors such as the size of the room, the number of occupants, the number of windows and doors, the number of electronic devices, the orientation of the room in relation to the sun and the amount of insulation, it is possible to determine the necessary capacity of the air conditioner to ensure a comfortable and efficient environment.
