Basic Understanding Air Conditioners

To ensure you are shopping for an air conditioner according to the right criteria, it is important to understand a few key terms:

  • Reverse Cycle: An air conditioning with both heating and cooling capabilities.
  • Inverter: Inverter air conditioning deliver a constant airflow for improved temperature regulation and increased energy efficiency.
  • Smart AC: Smart air conditioning connect to your home network so you can control and monitor their output through an app on compatible mobile devices.

What factors affect the size of air conditioning that I will need to know?

  • How much lighting you have?
  • Type and quantity of ducting
  • How many windows in the house?
  • How many people living in the house?
  • what is the foundation of your house as well as several other factors?

Use the formula to calculate the required air conditioning for your house

Before using the formula, first you need to know the length and width of your house. you need to multiply both length and width, then you have to add the area of each room together for the total and this figure needs to be in meter square. What you do next will depend on your ceiling height:

  • If your ceiling is 2.4m high, you will need to multiply the day time living area (m²) by 150 (watts)
  • If your ceiling is 2.7m high, you will need to multiply the daytime living area (m²) by 160 (watts)
  • If your ceiling is 3m high, you will need to multiply the daytime living area (m²) by 175 (watts)

As an example: For a house with a daytime living area of 120m² and a height of 2.4m,

the calculations would be: 110m² x 150 watts = 18,000 watts

18,000 watts = 18 KW,

18 KW unit is roughly the right size for this house.
