“…In comparison to a solid desiccant rotary cooling system, the achieved performance of the proposed system is much better. The dehumidification coefficient of performance achieved by Ge et al [19] for a solid desiccant cooling system at a regeneration temperature of 60 • C was 0.38 whereas in the present case it was 0.59. The performance of liquid desiccant assisted cooling system is expected to be higher compared to solid desiccant cooling system due to lower regeneration heat requirement.…”

“…These parameters are used for performance of a liquid desiccant enhanced cooling system to have lower regeneration temperature, no carryover of desiccant solution, and better supply air conditions. The relationships for dehumidification coefficient of performance (DCOP), cooling capacity, coefficient of performance (COP), electric coefficient of performance (ECOP), thermal coefficient of performance (TCOP) and sensible energy ratio (SER) are presented in Equations (5)-(10), respectively [19][20][21]:…”

Desiccant technology is found to be a good alternative to conventional cooling systems. It can provide better thermal comfort under hot and humid climatic conditions. The major component of a liquid desiccant cooling system is the desiccant dehumidifier which controls the latent cooling load. In this paper, a newly developed liquid desiccant enhanced evaporative cooling system has been tested experimentally. The effects of ambient conditions and other parameters on the performance of the system are investigated. The system performance curves which help to determine the air outlet conditions and coefficient of performance (COP) of the system are drawn for a wide range of ambient air humidity ratios (0.010-0.026 kg/kg), ambient air temperature (25-40 • C), process air flow rate (1.5-8.0 kg/m 2 ·s), regeneration air flow rate (1.5-4.5 kg/m 2 ·s), and regeneration temperature (55-85 • C). The results showed that better supply air conditions are achieved for hot and humid climatic conditions with effectiveness of the system largely dependent on process and regeneration air flow rates, regeneration temperature, and humidity ratio of process air. The dehumidification performance is increased by 62% for a change of ambient air humidity ratio from 0.01 to 0.025 kg/kg. The thermal coefficient of performance improved by 50% for the above variation in humidity ratio. This shows that such thermally activated systems are feasible options for hot and humid climatic conditions as indicated by better performance under these conditions.

“…It is clear that the regenerative temperature has a good influence on the performance and moisture removal efficiency. In order to with increases regeneration temperature, the moisture removal efficiency increase dramatically that has been confirmed by [15,20]. For example, at a constant speed 7rph and regeneration temperature T=80 o c amount of moisture removal efficiency is η=.22.…”

“…This model was used to optimize the influence of working conditions, revolution speed and desiccant wheel configuration on the performance of the desiccant wheel. Ge et al [17] developed a 1-D transient model to predict the performance of a compound desiccant wheel considering both the gas side resistance and the solid side resistance. The compound desiccant wheel was found to have a better performance in a climate with moderate temperatures or in a climate with a high humidity ratio.…”

A mathematical model for predicting the performance of a desiccant wheel with effective regeneration sector has been used. This model has been used to conduct a comparative performance of desiccant wheel with effective and ordinary regeneration sector. It was found that for all the cases considered in this study like rotation of wheel, regeneration temperature, velocity and ambient moisture, the desiccant wheel with ''effective regeneration sector'' gives better result as compared to ordinary regeneration sector.
