ABSTRACT: Modern society has an increasing dependence on vapor air conditioning and refrigeration systems which consume large amounts of electrical power that is often generated from fossil fueled power stations, with the effect releasing large quantities of greenhouses gases, such as CO2 into the atmosphere. These have led to increased focus on the development of innovative and ‘environmentally-friendly’ air conditioning systems taking advantage from traditional cooling methods. This paper seeks to present regenerative sub wet bulb evaporative cooling methods and to evaluate its performances with residential building thermal model. Heat and mass transfer model is constructed and typical condition are identified and used for the thermal model to evaluate the cooling cost of the system. The findings of this study are relevant to the neo-traditional cooled constructions in hot and dry countries.
KEYWORDS: Regenerative evaporative cooling, Sub-wet bulb temperature, Thermal model, cooling cost.
