Calculation program for air handling units (AHU)

AHULife

The basis of this tool is VDI Guideline 2067 Part 21. According to VDI 2067, a comfort range is defined in an h,x diagram for room air. The temperature and absolute humidity of the room air must lie within the limits of this comfort range. Depending on the outside air condition, different air treatment functions of the air handling unit (AHU) are addressed. The target values for temperature and humidity of the supply air are always selected in accordance with the internal loads in the room minimizing the energy required to maintain the comfort conditions.

This tool carries out an annual simulation of the energy requirement of your AHU configuration based on hourly resolved weather data for the 2010 test reference year of Germany's 15 climate regions. You have several options for heat and cold generation at your disposal to determine the final energy consumption. We therefore offer you the opportunity to view your AHU with different heat and cooling supplies and to determine the optimum generator for you.

The configuration of the AHU is freely selectable, allowing you to test any combination of components. Depending on which components you have selected, the different functions of an AHU are made possible.

Next to the yearly energy consumption, the tool also calculates economic indicators. This provides you information on the capital value, annuities and life cycle costs of the air handling unit for a period of your choice.

The AHULife-Tool has been developed for acamedic teaching. The tool uses simplifying model assumptions. The calculation results do not replace a technical planning. No liability is assumed for the correctness of the results. If you have any questions regarding the informative value of the results, please feel free to use the contact options provided.
