This research proposes an integrated building evaporative cooling assembly using pervious concrete acting as a thermally active system. The proof‐of‐concept prototype demonstrates the capacity of t...

Promoting the sustainability of building industry is one major approaches to addressing energy depletion and climate change. Here, we developed scalable cementitious cooling composites (CCCs) with superior energy-free performance environmental applicability. Optical properties, phase composition, microstructure, silica reactivity are characterized analyzed. Onsite measurements conducted evaluat...

The major aim of this study is to model the effect of outside temperature, watering, and airing on the inside temperature of a hybrid evaporative cooling system (HECS). There is great interest in evaporative cooling systems as a new storage system for fruit and vegetables for the purpose of energy saving. The heat transfer process of the HECS has not yet been well analyzed, so system identifica...

Avenues of water gain and loss in bees are examined here at two levels of organisation: the individual and the colony. Compared with the majority of terrestrial insects, bees have a high water turnover. This is due to their nectar diet and, in larger species, substantial metabolic water production during flight, counteracted by high evaporative and excretory losses. Water fluxes at the colony l...

Water evaporation has a marked effect on the passive rates of body temperature change of eristaline hoverflies. It results in the equilibrium temperature of these flies being significantly lower than ambient temperature. Different values for the cooling and warming constants are therefore obtained depending on whether equilibrium or ambient temperature is used as the baseline. Hence, care must ...

Leaves within a canopy may experience rapid and extreme fluctuations in ambient conditions. A shaded leaf, for example, may become exposed to an order of magnitude increase in solar radiation within a few seconds, due to sunflecks or canopy motions. Considering typical time scales for stomatal adjustments, (2 to 60 minutes), the gap between these two time scales raised the question whether leav...

Evaporative cooling has been successfully used to produce Bose-Einstein condensates ~BEC’s! inside magnetooptic traps with neutral atoms @1#. A number of questions arise as to the quantum state that is achieved, since this involves both the dynamics of the cooling process and the applicability of the ergodic hypothesis. Atom-atom interactions have a strong influence on the cooling process and t...
