In this paper the performance of a desiccant cooling system was evaluated. The system comprises a desiccant wheel in tandem with a thermal wheel with evaporative coolers in both air supply and return air streams before the thermal wheel. It allows cooling and dehumidifying air without using conventional refrigerants. A computer simulation was developed to study the effects of various designs and outdoor air conditions on the performance of the system. The simulations were run with SPARK, an object oriented program that allows creation of very flexible tools.
Local control of ventilation in large buildings is considered to be a main issue in energy savings regarding the huge energy losses that are usually induced by such large volumes. An efficient ventilation system and the development of local control ventilation strategies could prevent large buildings from having an unsuited or overvalued ventilation and reduce significantly the energy consumption.
La percepción del ambiente térmico no depende únicamente de los parámetros ambientales, sino que es un fenómeno que incluye muchos más factores del entorno interior y exterior, del sujeto que percibe estos parámetros. Incluso habría que considerar factore
The European Union’s (EU) Energy Performance of Buildings Directive (EPBD) aims to increase the energy performance (EP) of buildings by requiring EU Member States to develop an EP calculation methodology and to certify the EP of their buildings. Dynamic s
