Membrane based dehumidification and evaporative cooling using wire mesh media
Membrane dehumidification and evaporative cooling applications have the potential to significantly improve the energy efficiency of air conditioning equipment. The use of wire mesh media in such membrane applications is feasible but has not been studied extensively. Therefore, the aim of this work …

Solar desiccant evaporative cooling with multivalent use of solar thermal heat
Solar DEC (Desiccant and Evaporative Cooling) air-conditioning is a renewable technological approach to the future air-conditioning of buildings driven with solar-thermal heat. The principal acceptance of solar airconditioning has led to system prototypes mainly across Europe, however the diffusion …

Experimental studies of evaporative cooling and Bose Einstein condensation in an optical trap
… where atoms are firstly collected for their precooling in a 2D-geometry in a high pressure region. From this source region thereafter, the atoms are efficiently transferred into a conventional MOT inside a UHV chamber with capture rates exceeding 10^8 atoms/s. After a loading time of 1s and a …

An experimental study of evaporative cooling from liquid droplets impinging on a hot surface
… regimes observed in drop impacts during evaporative cooling of heated surfaces. We found four regimes which were named splashing, fizzing, flat film, and marbling based on the dynamic properties of the drop impact. We found that the emergence of these regimes is primarily controlled by …

Impact of surface area and porosity on the cooling performance of evaporative cooling devices
Evaporative cooling devices are low-cost, low-energy solutions for post-harvest storage of fruits and vegetables on farmlands. Surface area and porosity are two design parameters that affect the cooling devices' evaporation rate and cooling performance. Both design parameters lack prior systematic …

Analysis of heat transfer and fluid flow in an evaporating sessile droplet for evaporative cooling applications
Cooling is of critical importance for a number of fields, particularly in microelectronic devices and other miniaturized technology. The evaporation of the sessile liquid droplet facilitates the phase change of that liquid and provides cooling to the system, because a large amount of latent heat is …

Advances in the application of passive down-draft evaporative cooling technology in the cooling of buildings
A passive down-draft evaporative cooling (PDEC) tower is a component that is designed to capture the wind at the top of a tower and cool the outdoor air using water evaporation. While several different types of this particular system exist, PDEC tower with spray was studied in that it is flexible, …
