Performance calculation for air conditioners

Calculate approximately the required performance for your air conditioning – in our handy online calculator

Instructions for use:

You can use the following method to quickly and easily determine the cooling load required for your rooms. This cooling load calculation should be seen as a rough guide – it is not a substitute for an exact calculation in accordance with existing norms. Please do not hesitate to contact us if you have any questions.

The following items must be included in order to be able to determine the required air conditioning performance:

What is the total volume of the room to be climatised?
What is the approximate insulation value of the room to be climatised?
What additional heat load does the room to be climatised have?
