This thesis investigates the performance of a solid desiccant cooling system implementing in- direct evaporative cooling processes the aim is. To address the importance of desiccant air-conditioning (dac) systems, this paper discusses the comparison between dac and conventional vapor. In desiccant based evaporative cooling systems of these solid wastes as resource materials will help evaporative and desiccant cooling systems in a. A desiccant cooling system combined to an evaporative cooler  desiccant systems can use solid desiccants or liquid desic- cants.
The present review provides scientific and technical support on how solid desiccant-based hybrid cooling can be a supplement to the. A desiccant is a hygroscopic substance that induces or sustains a state of dryness (desiccation) in its vicinity it is the opposite of a humectant commonly encountered pre-packaged desiccants are solids that absorb air conditioning systems can be made based on desiccants desiccants are used in different kinds of. Solid desiccant air-conditioning systems can take care of both the sensible and latent load of a conditioned space, as well as of the fresh air requirements,.
Desiccant to its temperature of regeneration as shown in figure1 figure1: principle of desiccant cooling system 21 solid desiccant. Open cycle solid desiccant cooling systems is an alternative way of air conditioning, in comparison to conventional vapor compression systems these systems. Such a solid desiccant cooling system with a backup vapour compression system is simulated and the performance of the system is evaluated.

Dehumidification by desiccant is a new application in air-conditioning system this solar cooling system that used a lithium chloride in solid desiccant rotor. Different types of neural networks are applied to model the solid desiccant cooling systems with use of experimental data, an ann model was developed which. Desiccant systems, coupled with mechanical cooling, can avoid the need for reheat there are two broad categories -- liquid and solid desiccant systems.
Desiccant cooling is a better alternative to vapour compression cooling systems which consume lot of energy and also increase the cfc level. Providing insights for today's hvac system designer figure 2 “solid”-desiccant dehumidification wheel “cool+reheat” system, the cooling coil must cool the. A solid desiccant system commonly uses a solid desiccant embedded in a.
