TL;DR: In this article, an experimental investigation on collector efficiency and pressure drop in a solar air heater with multiple s-shaped ribs with gaps as the roughness element is presented, which can enhance the heat transfer between air and heat absorber plate sufficiently.

TL;DR: In this paper, the authors provide a comprehensive literature review to identify, classify, evaluate and analyze the performance of different methodologies, models and energy systems for isolated areas, and effective information could be provided to support decision-making toward to appropriate energy models and systems for isolating areas with different scales and demands.

TL;DR: A compact guide of existing model modification and novel model development regarding predicting global solar radiation, including input parameters, feature selection and model development for machine-learning models is provided.

TL;DR: In this paper, the authors investigated the relationship between temperature and learning performance and found that thermal discomfort caused by high or low temperatures had a negative impact on pupil learning performance, while carbon dioxide concentration, acoustics, and illumination were maintained at the same level.

TL;DR: In this paper, the optimum opening and closing modes in the management of air vents have been obtained by testing and analyzing thermal performance parameters of a trombe wall installation, including air vent velocity, air vent temperature, the temperature distribution of air layer and indoor air temperature.
