Monthly-averaged daily global irradiation data are now easily available from NASA website for any global location. Using established models it is then possible to decompose the daily to averaged-hourly global irradiation. The missing link so far has been hourly averaged diffuse irradiation. In this article data was pooled from 14 world-wide locations to obtain a regression model to complete the ab...... hiện toàn bộ
Năng lượng là yếu tố không thể thiếu cho mọi hoạt động của con người. Giao thông, sản xuất công nghiệp, thương mại, truyền thông, v.v. phụ thuộc vào khả năng cung cấp năng lượng. Truyền thống, người tiêu dùng đáp ứng nhu cầu năng lượng của họ bằng cách mua điện và nhiên liệu từ các công ty phân phối. Đối với việc sản xuất năng lượng điện mà người tiêu dùng tiêu thụ, một phần lớn được sản xuất tại ...... hiện toàn bộ
As one of the most energy-, emission- and pollution-intensive industries, iron and steel production is responsible for significant emissions of greenhouse gas (GHG) and air pollutants. Although many energy-efficiency measures have been proposed by the Chinese government to mitigate GHG emissions and to improve air quality, lacking full understanding of the costs and benefits has created barriers a...... hiện toàn bộ

The building sector accounts for around 40-50 % of the energy consumed in developing countries and contribute over 30 % of CO2 emissions. In Cameroon, the electricity access is less than 5 % in rural areas against 50 % in urban areas. All sectors combined the Cameroonian final energy consumption amounts to approximately 5235 kilo-tonnes of oil equivalent (Ktoe) and 73 % of this energy are assigned...... hiện toàn bộ

Urban and building energy simulation models are usually driven by typical meteorological year (TMY) weather data often in a TMY2 or EPW format. However, the locations where these historical datasets were collected (usually airports) generally do not represent the local, site specific micro-climates that cities develop. In this paper, a humid sub-tropical climate context has been considered. An ide...... hiện toàn bộ
The excellent thermal insulation performance of vacuum insulation panels (VIPs) make them widely applied in energy conservation fields, especially in buildings engineering. This research work proposes a simple, yet extremely effective, alternative model for prediction of the effective thermal conductivity (ETC.) of VIPs. The ETC. of VIPs is function of the thermal conductivity of the core material...... hiện toàn bộ

This study explored the effect on photocatalytic degradation in aqueous solution with high- concentration ammonia where immobilized TiO2 on glass beads was employed as the photocatalyst. TiO2 film was prepared via deep coating TiO2 in a sol–gel system of tetrabutyl titanate precursor and calcinating it at the temperature between 400 to 650 °C. Several crucial factors affecting on the rate of remov...... hiện toàn bộ
