Investigation of a Desiccant Assisted Geothermal Air Conditioning System

169 Seiten, Dissertation Technische Universität Hamburg-Harburg (2018), Softcover, A5

Zusammenfassung / Abstract

The steadily increasing air conditioning demand is a major challenge in the context of global emission control. In this work, a desiccant assisted geothermal air conditioning system is investigated experimentally and based on computer aided simulations. The experimental investigations reveal that electricity savings of up to 71 % compared to a conventional reference system are possible and that borehole heat exchangers can be utilized as a highly efficient heat sink within the system configuration. A system model is used to investigate the system performance for five different locations within the United States. While the system is not cost competitive at most locations, it enables lifetime CO2 savings of up to 91 %.
