Đánh giá tính khả thi kinh tế của việc áp dụng hệ thống trigeneration tại một khách sạn nhỏ Dịch bởi AI Tập 2 - Trang 1-9 - 2016
Clito Afonso, Carlos Rocha
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
Sustainable urbanism: towards a framework for quality and optimal density? Tập 2 - Trang 1-13 - 2016
Steffen Lehmann
The question of density is closely connected to urbanization and how our cities
may evolve in the future. Density and compactness are two closely related but
different criteria, both relevant for sustainable urban development and the
transformation of cities; however, their relationship is not always well
understood. While a high degree of compactness is desirable, too much density
can be detrimen... hiện toàn bộ
Planned energy-efficient retrofitting of a residential building in Italy Tập 1 - Trang 1-19 - 2015
Enzo Zanchini, Claudia Naldi, Stefano Lazzari, Gian Luca Morini
The planned energy-efficient retrofitting of a residential building in Bologna,
North-Center Italy is presented. The building is a detached house with an
unheated basement, three floors with 2 apartments each, and an unheated attic.
The total heated floor area is 281.9 m2. The external wall is made of solid
brick masonry and most windows are single glazed; no thermal insulation is
present. Space h... hiện toàn bộ
Development of Low-cost indigenous filtration system for urban sullage: assessment of reusability Tập 2 Số 1 - Trang 1-8 - 2016
Sikder, Tajuddin, Hossain, Zakir, Pingki, Priangka Bhattacharya, Biswas, Jussi Dayna, Rahman, Mostafizur, Hossain, Shakhaoat, Saito, Takeshi, Kurasaki, Masaaki
Treated sullage water could be the answer to urban water scarcity. In this
study, urban sullage water was subjected to various tests to determine a number
of physiochemical parameters, heavy metal content and coliform count. Obtained
results were compared with the Dhaka Water and Sewerage Authority (DWASA) water
samples. The sullage water was then treated using a proposed filtration system
with in... hiện toàn bộ
CFD simulation and validation of self-cleaning on solar panel surfaces with superhydrophilic coating Tập 1 - Trang 1-15 - 2015
Jin Hu, Nicolas Bodard, Osmann Sari, Saffa Riffat
Solar panel conversion efficiency, typically in the twenty percent range, is
reduced by dust, grime, pollen, and other particulates that accumulate on the
solar panel. Cleaning dirty panels to maintain peak efficiency, which is
especially hard to do for large solar-panel arrays. To develop a transparent,
anti-soiling Nano-TiO2 coating to minimize the need for occasional cleaning is
the purpose of ... hiện toàn bộ
Photocatalytic degradation of high ammonia concentration wastewater by TiO2 Tập 1 - Trang 1-12 - 2015
Xue Gong, Haifeng Wang, Chun Yang, Quan Li, Xiangping Chen, Jin Hu
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
Monthly-averaged hourly solar diffuse radiation models for world-wide locations Tập 1 - Trang 1-8 - 2015
T. Muneer, EJ Gago, S. Etxebarria
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
