The Performance of a Regenerative Heating and Cooling System

This book reports on a study of the renewable energy-
based heating and cooling systems of a multipurpose
building. The first objective of the investigation
was to demonstrate the potential of solar-assisted
cooling, the second focused on the total energy
balance of the building. For base-load heating and
cooling, the building is equipped with a ground
source heat pump, supplied by a ground storage. For
solar cooling, the building is equipped with solar
collectors and two desiccant evaporative cooling
(DEC) plants. During the first year of operation,
significant problems occurred in the operation of
the DEC-plant and the heat pump. The heating energy
consumption of the building was acceptable, but the
calculated primary energy consumption was too high.
In comparison to an conventional system the
calculated CO2 saving was negative. Since user
satisfaction was high, the suboptimal operation of
the plant was not apparent to the building users.
The most important conclusion from this research
project is that without careful monitoring, the
energy-saving opportunities provided by the
installation of innovative systems may not, in
practice, be realised.
