Optimum of heat recovery

This data file is an Excel tool to calculate the optimized temperature transfer efficiency and the combinded pressure loss of a heat recovery system based on an optimized air velocity.
The calculation is based on the following input factors:
- Price for Heating 0.04 to 0.16 €/kWh
- Price for electricty 0.06 to 0.36 €/kWh
- Extract air temperature 18 to 28 °C
- Supply air temperature 14 to 22 °C
- Out door air temperature -15 to +2.5 °C
- Load 40 to 100%
- Operating time 2,350 to 8,760 h/a
The calculations are based on multi-dimensional optimisations of a medium air handling unit.
The proposed model is based on individual regressions of the various influencing factors. A factor is derived based on a change in the respective influencing parameter.
The modell may be comparerd with the multiple regressions without energy prices and supply air temperaturen are available at:

The input data are highlighted in green.
The uncertainty of the modell is calculated and shown as well.
