This paper presents a numerical study of the thermal performance of fins mounted on the bottom wall of a horizontal channel and cooled with either pure water or an Al2O3-water nanofluid. The bottom wall of the channel is heated at a constant temperature and cooled by mixed convection of laminar flow at a relatively low temperature. The results of the numerical simulation indicate that the heat ...

This research is proposed to fully investigate the performance of a single-effect water/lithium bromide absorption chiller driven by geothermal energy. Since cycles are considered as low-grade energy cycles, this innovative idea rejecting fluid from single-flash power plant with would serve efficient, economical, and promising technology. In order examine feasibility approach, residential build...

In this thesis work, a comprehensive static data center model with raised floor design is developed with improvements based on previous master thesis work. Enhancement work focuses on IT virtualization technology, a general server model, more detailed chiller system and mechanical system, novel modeling methodology for power devices (PDU and UPS). Besides, the temperature of CRAH supply air, CR...

The lithium bromide chillers supplied from solar collectors are used to provide proper environmental conditions into industrial and civil buildings. To maintain the appropriate values for the temperature into the chiller's boiler, a control unit is introduced to avoid crystallization of the absorbent. The liquid flow process of the absorbent within the pipes of the chiller is a non-linear proce...

The method used this research is experimental method. testing process carried out at Refrigeration Laboratory In experiment,...

A rigorous mathematical approach is developed for optimization of sustainable single-effect water/Lithium Bromide (LiBr) absorption cooling cycles. The multi-objective formulation accounts for minimization of the chiller area as well as the environmental impact associated with the operation of the absorption cycle. The environmental impact is quantified based on the global warming potential and...
