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.
This article presents the study done on an individual house located in Macon, France. From the model of a house called ‘reference house’, in conformity with French thermal regulation, different parameters concerning the walls, the screenings or the ventil
In Cuba the climate is tropical, with average solar radiation of 5.5 kW-h/m2and an annual average temperature of 25 °C. The relative humidity is high all of the time, with an annual average between 75 % and 85%. Because of this it is very interesting to t
The use of heat produced by solar thermal collectors is an interesting option for thermal driven airconditioning process. Three technologies are commercially available: absorption, adsorption anddesiccant cooling systems. This paper is focused on solar desiccant cooling and solar absorptionsystems. The aim of the study is to assess energetic and comfort performances of these solar coolingsystems integrated in an office building.
