Hybrid Ventilation with Innovative Heat Recovery—A System Analysis

Davidsson, Henrik LU ; Bernardo, Ricardo LU orcid and Hellström, Bengt LU (2013) In Buildings 3. p.245-257
Abstract
One of the most important factors when low energy houses are built is to have good heat recovery on the ventilation system. However, standard ventilation units use a considerable amount of electricity. This article discusses the consequences on a system level of using hybrid ventilation with heat recovery. The simulation program TRNSYS was used in order to investigate a ventilation system with heat recovery. The system also includes a ground source storage and waste water heat recovery system. The result of the analysis shows that the annual energy gain from ground source storage is limited. However, this is partly a consequence of the fact that the well functioning hybrid ventilation system leaves little room for improvements. The... (More)
