Abstract

Energy use in buildings has become a topic of serious discussion due to the increased living standards coupled with the increased electricity and fuel price. United Arab Emirates (UAE) has hot and humid weather conditions for most of the year and it results in excessive use of cooling systems during summer. As a result, cooling consumes about 50% electrical energy annually. The development of energy efficient ventilation air conditioning systems will result in considerable energy reduction. Executive Affairs Authority in Abu Dhabi is interested to establish minimum energy performance standards (MEPS) by analyzing different heat pump design options suitable to UAE condition. This research is focused on analyzing various conventional and innovative design configurations. Flexible component based heat pump models are developed including the sub models for evaporator, compressor and condenser. The different design configurations are then tested and compared for given boundary conditions. Evaporatively-cooled condenser is considered as a potential design feature due to its good performance in hot and humid conditions. Novel dedicated outdoor air system (DOAS) configuration, Closed DOAS, is presented and analyzed.
