Parametric study of a heat exchanger for a hybrid ventilation system.

Summary

Heat recovery from the ventilation air is one of the key components in low energy houses. The energy use in a building would increase considerably without heat recovery on the ventilation air. However, standard mechanical ventilation units with heat recovery use considerable amounts of electricity in order to run the fans. One way to reduce this is to use natural or hybrid ventilation. However, this technology normally has no provision for recovering any heat from the outgoing ventilation air. This results in both a high need for thermal energy and low thermal comfort. This article describes a parametric study of a heat exchanger designed for heat recovery in a natural/hybrid ventilation system. Different materials and different geometries are investigated in order to optimise the performance. The study shows a small potential for the improvement of the heat exchanger.
