Simulation and optimization of energy consumption in cold storage chambers from the horticultural industryInternational Journal of Energy and Environmental Engineering - Tập 5 - Trang 1-15 - 2014
Paulo Brito, Pedro Lopes, Paula Reis, Octávio Alves
The use of industrial cooling for food preservation has been revealed to be an efficient and widely employed technique, from harvest time to final consumption by the customer. However, the most used method to generate that cold (based on the compression refrigeration cycle) requires a considerable amount of electric energy, especially if no appropriate energy efficiency measures are implemented in...... hiện toàn bộ
FB720 project: development of new solar control glazing with passive seasonal discrimination of solar radiation incomesInternational Journal of Energy and Environmental Engineering - Tập 6 - Trang 309-317 - 2015
Pablo Garrido, Joan Lluís Zamora, José Manuel Marco, Moisés Lostao
Currently, the most balanced technical solution for sun protection of glazed areas is the Venetian blind, because it prevents the entry of direct solar radiation, but at the same time provides a view of the outside and allows light to diffuse into the building. The current challenge is to find an improved, integrated technical solution at an affordable cost that requires low maintenance, is suitab...... hiện toàn bộ
Effects of coupled heat sources in a triple power cycle: thermodynamic, economics and environment analysis and optimizationInternational Journal of Energy and Environmental Engineering - Tập 13 - Trang 407-428 - 2021
Mahdi Alibeigi, Somayeh Davoodabadi Farahani, Sina Amiri Hezaveh
In this study, the thermodynamic and economic analysis for a triple combination including the Brayton cycle (GT), reheat cycle and an organic Rankine cycle, and Brayton cycle by coupling geothermal with biomass energy source and solar energy source is presented. Thermodynamically and economically, the effects of changing working fluid, air, CO, CO2, N2, and NO2 are studied for pressure ratio and a...... hiện toàn bộ
Optimization of ethanol fermentation from discarded carrots using immobilized Saccharomyces cerevisiaeInternational Journal of Energy and Environmental Engineering - Tập 6 - Trang 129-135 - 2014
Adriana L. Clementz, Nora R. Aimaretti, Debora Manuale, Agustín Codevilla, Juan C. Yori
Discarded carrots are a valuable source of biomass amenable for valorization. Their use as raw material for ethanol production by fermentation, using yeasts immobilized in Calcium alginate, was proposed. The biocatalyst immobilization method, the existence of internal and external mass transfer limitations, the effect of the initial pH and the reuse of immobilized yeasts were particularly evaluate...... hiện toàn bộ
Preliminary assessment of uranium mining legacy and environmental radioactivity levels in Sabugal region, PortugalInternational Journal of Energy and Environmental Engineering - Tập 7 - Trang 399-408 - 2016
Fernando P. Carvalho, João M. Oliveira, Margarida Malta
An environmental radioactivity survey carried out in the Sabugal region, Portugal, showed enhanced radioactivity levels in surface water streams related to water discharges from old uranium mines. Water from irrigation wells in this region displayed variable radionuclide levels due to natural occurrence of radionuclides and to contamination by mine water drainage. Horticulture products grown near ...... hiện toàn bộ
