Performance analysis of four-partition desiccant wheel and hybrid dehumidification air-conditioning system

Performance analysis & energy benefits of a desiccant based solar assisted trigeneration system in a building

“…The two desiccant rotor intercooled cycle, enables greater dehumidification from what would otherwise be a very low temperature heat source from the flat plate solar collectors. Specifically, conventional desiccant cooling cycles require temperatures of around 80 C for adequate dehumidification, whereas this system runs at temperatures as low as 60 C which enables much higher solar collector efficiency than otherwise achieved [16,17]. Furthermore the system has been designed and implemented as an integrated whole-ofbuilding solution which simultaneously provides both heating, ventilation and air-conditioning (HVAC) and domestic hot water (DHW).…”

Multi-physical continuum models of thermochemical heat storage and transformation in porous media and powder beds—A review

“…Thermochemical systems can further serve as a sustainable heat pump technology for the recovery of low-grade waste heat [10] as well as heat from renewable sources, such as geothermal or solar heat [11][12][13][14]. Such chemical heat pumps can be used for cooling applications [11,[15][16][17][18][19] and can be integrated into trigeneration (combined heating, cooling and power) systems [12].…”

Influence of the number of stages on the heat source temperature of desiccant wheel dehumidification systems using exergy analysis

“…(7) and (8) show that under the fixed inlet and outlet states of the processed air, when the exergy destruction decreases, E c þ E h and P can decrease and the system's exergy efficiency can increase.…”

“…In many studies, researchers have tried to reduce t reg and adopted high-efficiency renewable heat sources such as solar energy [5] and heat pump systems [6,7] in place of electrical heating. t reg can be reduced through pre-cooling [2,8], adopting two-stage desiccant wheel systems [2,6e11], or using desiccant wheels with a facial area ratio and an air flow rate ratio of the two streams of air both equaling to 1 [2].…”
