TL;DR: In this paper, the advantages of DCHEs over other dehumidifiers are established, and a comprehensive review of various desiccant materials and binders used in DCHE is carried out.
118 citations
TL;DR: In this article, a cross-flow membrane liquid desiccant dehumidifier and a counter-flow dew point evaporative cooler were developed and investigated to achieve sufficient moisture removal and temperature reduction.
53 citations
TL;DR: In this paper, a 2D mathematical model has been formulated to simulate the heat and mass transfer performance of the dew point evaporative cooling (DPEC) and the model agrees well with the acquired experimental data with a maximum discrepancy of ±7.0%.
42 citations
TL;DR: In this article, the authors studied the flash evaporation phenomenon of a hot water jet sprayed into a low-pressure chamber and found that the mean droplet diameters of the spray are several orders of magnitudes smaller than the nozzle diameter.

TL;DR: In this article, a spray-assisted low-temperature desalination system powered by solar thermal energy was investigated, and a numerical model was developed to predict the dynamical system performance.
36 citations
TL;DR: A 3E analysis and multi-objective optimization exercise of a spray-assisted low-temperature desalination technology through a judiciously developed mathematical model revealed that the specific energy consumption highly conflicts with the initial investment, while the specific CO2 emission and the initial investment present a positive correlation.
36 citations
TL;DR: In this paper, a simple theoretical model has been presented to quantify the heat and mass transfer rates of the water-cooled liquid desiccant dehumidification and cooling processes for air-conditioning applications.
34 citations
TL;DR: In this article, an exergy analysis of the counter-flow dew point evaporative cooler is conducted by incorporating the first law of thermodynamics for energy and mass balances, which reveals that the saturated air state at ambient temperature is the rational dead state to properly describe the physical mechanisms involved in the dew-point evaporative cooling process.
33 citations
TL;DR: In this paper, the transient and steady-state analysis of the counter-flow dew point evaporative cooler has been investigated, and the results revealed that the transient responses of the channel plate and the cooler agreed well with an exponential decay function.
32 citations
TL;DR: In this paper, a comparative study on the performance of counter-flow dew point evaporative coolers with two different configurations (type A and type B) was conducted. And the results showed that the type B configuration has a higher cooling effectiveness and lower product temperature than type A configuration; and the developed dimensionless product air temperature correlation for type B adhered closely to simulated results.
32 citations
TL;DR: In this paper, the authors investigated a vacuum multi-effect membrane distillation system (V-MEMD) for liquid desiccant regeneration, and the results showed that the regenerator performance degraded at higher feed concentrations, while a higher hot water temperature promotes regeneration rate and thermal efficiency.
TL;DR: In this article, a two-dimensional computational fluid dynamic model is developed to simulate the evaporative cooling process within the dew point evaporative cooler and compute the outlet data for the NTU-Le-R model.
TL;DR: In this paper, the authors describe the development of a hybrid solution that improves air dehumidification, which comprises the integration of a composite desiccant and a nano-woven membrane.
TL;DR: In this paper, a hybrid cryo-RFA system under thermal stress control is proposed, and a three-dimensional finite difference analysis is employed to simulate the combined cryosurgery and RF heating protocol.
TL;DR: Clotting of blood elements or intraluminal thrombus (ILT) is known to develop within aortic aneurysm sacs, and is clinically associated with the dilation and rupturing of aneurYSms, however, the un...
