Overview
Increasing outdoor temperatures and the linked rising humidity lead to additional energy and power demand for dehumidification. In addition, the demand for higher indoor air humidity in winter leads to additional power peaks at low outdoor temperatures. The project investigates to what extent combined humidity and heat recovery (so-called enthalpy recovery, abbreviation ERC) can reduce the additional demand, especially the power peaks, and how this can be implemented with the state of the art, developments and requirements. For experts in planning and operation of buildings, the effects of ERC on the design and operation of new and existing air handling units and static cooling systems are explained. For energy standards, it is shown how ERC can be taken into account to prevent power peaks and additional energy demand due to climate change and increased indoor humidity requirements.
