Problem of heat pumps in central RussiaApplied Solar Energy - Tập 48 - Trang 24-32 - 2012
S. N. Trushevskii, I. V. Mitina
This article describes the problems of heat pumps due to climatic conditions and the characteristics of energy sources. As energy sources for heat pumps, solar power, air, groundwater, soil, and rejected heat are considered. It is shown that in central Russia it is only rational to use waste heat as an energy source for heat pump systems.
The benefits of the transition from fossil fuel to solar energy in Libya: A street lighting system case studyApplied Solar Energy - Tập 53 - Trang 138-151 - 2017
Ashraf Khalil, Ali Asheibi, Zakariya Rajab, Moneer Amhammed
The Libyan economy is dominated by the oil and the gas industry which are considered as the primary energy sources for the generating power plants. With the increased energy demands in the near future, Libya will be forced to burn more oil and gas. This, in turn will result in reducing the country revenue, threatening the economy and increasing the CO2 emission. This triggers the alarm for Libya t...... hiện toàn bộ

Optical-geometric parameters of a linear Fresnel mirror with flat facetsApplied Solar Energy - Tập 50 - Trang 168-170 - 2014
Sh. I. Klychev, A. A. Abdurakhmanov, A. A. Kuchkarov
This paper studies linear Fresnel mirrors (LFMs) with flat facets. A model and a program for calculating the parameters and concentration of LFMs with flat facets have been developed. It is shown that LFMs can provide in increased concentration by up to 30 times at a number of facets of about 50 while ensuring the high uniformity of the concentrated radiation at the receiver.
Approximate evaluation of operating conditions and effectiveness of solar impurity thermovoltaic elementApplied Solar Energy - Tập 45 - Trang 73-76 - 2009
M. S. Saidov
The effectiveness of solar impurity thermovoltaic elements based on semiconductors with forbidden gap width 0.3 eV with thin highly doped p- and n-layers with concentration ∼5 × 1019 cm−3, containing in addition a deep impurity with concentration ∼4 × 1018 cm−3 and ionization energy 0.15 eV, is shown to reach 30–40% with solar radiation intensity 0.1 W/cm2.
