Optimum of heat recovery
Description
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: https://data.mendeley.com/datasets/w7sw8njrz5/1 (DOI: 10.17632/w7sw8njrz5.1) The input data are highlighted in green. The uncertainty of the modell is calculated and shown as well.
