Review of Dew Point Evaporative Cooling Technology for Air Conditioning Applications

Applied Sciences, 2021
Indirect evaporative cooling has the potential to significantly improve the natural environment. It follows from a significant reduction in electricity consumption in the hot period, and hence lower operating costs for cooling systems.

Feasibility of Reducing Electricity Consumption of Air Conditioning Equipment by Condenser Direct Evaporative Cooling Technology. Example of Case Study in Dubai

Atmosphere, 2021
The use of air conditioning technology is accompanied by an increase in electricity consumption, which is linked to an intensification of fossil fuel extraction. This in turn calls for developing cooling solutions of higher energy efficiency.

Calculation of evaporative-radiant cooling of recycled water in summer air-conditioning systems [PDF]

E3S Web of Conferences, 2023
The paper describes the calculation of evaporative-radiant cooling of recycled water in summer air-conditioning systems. A differential equation for the heat balance of water flowing down an inclined plane is derived.

Evaporative Cooling of Sodium Atoms [PDF]

Physical Review Letters, 1995
We have observed evaporative cooling of magnetically trapped sodium atoms. A novel technique, rf induced evaporation, was used to reduce the temperature by a factor of 12 and increase the phase space density by more than 2 orders of magnitude. The elastic collision cross section of cold sodium atoms in the $F\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}

Evaporative Cooling of Antiprotons to Cryogenic Temperatures [PDF]

Physical Review Letters, 2010
We report the application of evaporative cooling to clouds of trapped antiprotons, resulting in plasmas with measured temperature as low as 9~K. We have modeled the evaporation process for charged particles using appropriate rate equations. Good agreement between experiment and theory is observed, permitting prediction of cooling efficiency in future ...

Laser-Assisted Evaporative Cooling of Anions [PDF]

Physical Review Letters, 2019
We report the first cooling of atomic anions by laser radiation. O^{-} ions confined in a linear Paul trap were cooled by selectively photodetaching the hottest particles. For this purpose, anions with the highest total energy were illuminated with a 532 nm laser at their maximal radial excursion.

Energy Efficiency in Greenhouse Evaporative Cooling Techniques: Cooling Boxes versus Cellulose Pads

Energies, 2014
Evaporative cooling systems using a combination of evaporative pads and extractor fans require greenhouses to be hermetic. The greatest concentration of greenhouses in the world is located in southeast Spain, but these tend not to be hermetic structures ...

Investigating the cooling of solar photovoltaic modules under the conditions of Riyadh

Journal of King Saud University: Engineering Sciences, 2023
Cooling enhances the energy conversion efficiency and output of photovoltaic (PV) panels. In this work, the effects of natural convection, forced convection, and evaporative cooling on the performance of polycrystalline PV panels were investigated.
