The paper presents experimental data and results from a prediction tool for the performance of a desiccant loop cooling system. The experiments are performed under a variety of high humidity and hot ambient conditions and the system performance is described. One of the experimental conditions is typical of many Indian cities and the systems appropriate for those cities are established. A simulation program that can predict the performance of the desiccant loop is developed. The simulation results show that this system can work as effectively as vapor compression air-conditioning for certain ambient conditions whereas it can function as a pre-cooler to a vapor compression system under more severe conditions, resulting in a reduced power consumption. The results presented in the paper give a guideline to practicing engineers as to when a desiccant loop cooling system would be useful. A simple payback analysis and a lifecycle cost analysis shows that a desiccant cooling system with a waste heat recovery recuperator is an economically viable investment.

“…Thus, it is found that the ventilation operating mode is more suitable for mile climate while the recirculation operating mode is more effective for hot and humid tropical climate. That is why optimal configuration should be adopted while using it for variable outside climatic conditions for better operational economy [41][42]. Desiccant assisted cooling system described above can effectively handle sensible heat load by passing warm and dehumidified process air over direct or indirect evaporative coolers to meet the supply design condition [43][44][45][46][47][48].…”

The solid desiccant based dehumidifier used in conjunction with the conventional HVAC combines the dehumidification of solid desiccant system and with the cooling capacity of the conventional air conditioning system. This hybrid cooling system provides thermal comfort to the occupants of the conditioned space. The hybrid systems main appeal lies in the fact that, it consumes much lesser high grade electrical energy as compared to the dedicated standalone traditional air conditioning systems. The electrical energy usage is possible still lower by use of primary energy sources for to supply the thermal energy needed for the desiccant regeneration. For this purpose freely available renewable solar energy or industrial waste heat can also be used for the regeneration heat source. Sometimes it is also possible to provide condenser waste heat for the part of desiccant reactivation heat supply may increase the overall performance of the system. It was also found that this cooling system with use of air to air waste heat recovery wheel performed better than without it in terms of dehumidification as well as cooling performance. The present study report important literature survey on the dehumidification potentials of desiccant integrated hybrid cooling system operating in hot and humid climates.

“…Therefore, the recent advances in renewable energy systems and clean, efficient, sustainable technologies are chosen from energy conservation point of view and substantially reducing major greenhouse gas emissions resulted from the building cooling while ensuring suitable conditions for users' comfort. Desiccant cooling is one of these technologies, and it could be able to address the issues raised above [17][18][19][20][21]. By use of desiccant based innovative dehumidification and cooling techniques moisture of indoor air can be controlled effectively and consume less power as compared to the traditional HVAC devices in building.…”

Due to its sustainable cooling design and inexpensive operation, desiccant based dehumidification and cooling systems have been popular in recent years for humid areas. In general, the desiccant cooling used in conjunction with evaporative cooling as two separate types of configurations according to direct or indirect cooling. The relative humidity of moist outside air can potentially be controlled by both the systems during dehumidification and cooling to produce indoor thermal comfort. The solid desiccant-assisted evaporative cooling technologies may enable the use of the technique in a wider variety of climates, including those with high humidity. The development of innovative desiccant materials, improvement of the structure and material of the dehumidifier setup, desorption consumption rate and operating strategy of the system are some of the potential research possibilities and recommendations that were made. According to this review study, the desiccant integrated innovative cooling system is found as promising alternative to the traditional vapor-compressed cooling system and with the right setup, may be used in hot, humid situations. Keywords: Dehumidification, Desiccant cooling, Performance, Regeneration.
