5 Factors in Determining the Required Capacity of Your Split Air Conditioner

Airconditioner on a wallOne of the questions you should ask yourself before you purchase a split air conditioner for your home is, “What should the capacity of the air conditioner be?” You need to answer this important question because:

If you get an air conditioner with a capacity that is lower than what is needed to manage room temperature efficiently, the compressor will have to keep running longer than normal at maximum power in order to reach the desired temperature. This results in a higher energy consumption and reduced service life of the compressor. If the difference between the needed and provided capacity is so big, then this will further result in discomfort among the room’s occupants.
Whilst it is generally okay to have more capacity than what is needed, it could result in unnecessary expenses.

Computing for the Right Capacity

To calculate the right cooling capacity and size of your air conditioner, you need to consider these major factors:

1. Room Volume. To compute the room volume, multiply the length by the width and height of the room. For example, if the room has a length of 5 meters, a width of 4 meters, and a height of 3 meters, the room volume is 60 cubic meters.

2. Average number of Occupants. Conduct Air Conditioning reminds home and building owners of the fact that people naturally generate heat, therefore, increasing the room temperature. Your split air conditioner will have to displace this aside from the natural heat in the room.

3. Lights, Electrical Appliances and Gas Stoves. When turned on, these devices generate heat, which the air conditioner will likewise need to displace, in order to achieve the desired temperature.

4. Size and location of windows. Sunlight enters through the windows and this can contribute significantly to the heat load of the room and, consequently, to the total heat that the air conditioner must displace.

5. Materials used for the walls. This has to do with the insulating properties of the material that the walls are made of; i.e., their ability to keep external heat out. Wood has poor insulating properties, whilst concrete is an excellent insulator.

To maintain a comfortable room temperature, you need to get an air conditioning unit that is appropriate for the room. By calculating the required capacity of your AC based on these factors, you can create an ideal home environment and avoid unnecessary expenses.
