The Performance of a Regenerative Heating and Cooling System: System Analysis Carried out in a Multipurpose Building Review

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.

From the author: The central thrust of this paper is to introduce the concept of a balanced flow Dedicated Outdoor Air System (DOAS) integrated, physically and functionally, with a pressurization unit. The incentives for this concept include: improved total energy recovery (TER) equipment efficiency, lower first cost, no increase in the installation cost, reduced fan parasitic energy use, predictable building pressurization performance, and a very modest additional first cost for reserve capacity. This may be the next step in the migration path toward improved performance at reduced first cost for DOASs
