Figure 2 Working of the standalone solid desiccant cooling system The schematic of a hybrid solid desiccant cooling system coupled with the vapor compression air conditioning system is shown in Figure 3. The air from the ambient is sent through the desiccant wheel. It is specified as point 1. The air after undergoing dehumidification by the desiccant wheel is delivered as hot and dry air. This is represented as point 2. The hot dry air is sent through the Non-Woven Fabric Type Indirect heat exchanger. The air is sensibly cooled by the indirect heat exchanger and delivered as substantially cooled air represented by point 3.
