Air Conditioning Power Requirements

The heat balance determines not only the power rating but also the type of air conditioning unit that is required or best suited for any application. An error can end up costing you extra money on your energy bills.

  • Air conditioning systems typically increase your electricity consumption by 15 – 20% depending on its usage.
  • If the air conditioner is undersized (without sufficient power) it will be able to cool or heat the area efficiently and will use more energy as a result.
  • If the air conditioner is oversized (excessive power) it will cost more to run and maintain.

Deciding the optimum power requirement and type of air conditioning unit is best done by a professional installer. Obtaining the correct heat balance involves a number of factors which need to be taken into account such as:

  • Area
  • Ceiling height
  • Number of windows
  • Window material: wood, uPVC, aluminum
  • Geographic location
  • North or south facing
  • Number of occupants
  • Number of electrical appliances in the area

How to estimate the power requirements of a monoblock air conditioning unit ?

The figures shown below are approximate and do not constitute a perfect heat balance. Use them as a guide for purchasing a monoblock air conditioner.

Other types of air conditioning system should involve consulting a professional air conditioning (HVAC) engineer in order to obtain the most suitable system based on your requirements and property.
