In this report different air-water heat pump cycles under the operating conditions of the retrofit market and in the low heating power range are examined. The already existing heat pump models show excessive power and efficiency loss at very low ambient te ...
The objectives of the present work is to theoretically and experimentally demonstrate the advantages of a two-stage cycle equipped with an economizer and single variable speed compressor for heat pumps using air as cold source. Furthermore, an efficient de ...
Combined cycle power plants burning natural gas offer various advantages such as high efficiency, low environmental impact, smaller specific investments and shorter construction periods which lead to a more flexible response to uncertain future electricity ...
The light-induced degrdn. of Tinopal DMS-X, a stilbene type fluorescence whitening agent (FWA) which is quite resistant to biodegrdn., is described. This substance has been chosen for the study of the titania-induced degrdn. of polycyclic stilbenes since i ...
Competition in liberalized energy markets and increasing environmental concerns call for industrial power generation that is both cost effective and environmentally friendly. This is true for both the operation of existing as well as the development of new ...
Un nouveau concept de centrale électro-solaire, développé au LENI et baptisé PAESI, repose sur l’utilisation rationnelle d’un ajout de combustible fossile, c’est à dire en exploitant au maximum son haut niveau exergétique dans le cadre d’un cycle combiné s ...
Double cyclization of linear pentapeptide I by treatment with CsF in DMF at -5 Deg gives a model bicyclic (C)-O-(D)-O-(E) ring analog of vancomycin in a one step. [on SciFinder (R)] ...
Integrated solar combined cycle systems (ISCCS) represent, both economically and energetically, a promising alternative for the conversion of solar energy while offering a guarantee of a minimum power supply independant of the level of solar radiation. The ...
Exergetic analysis is derived from the First and Second Laws of thermodynamics is shown to be an excellent tool to analyse and characterize industrial processes. A coherent link to pinch technology is shown which allows the designer to extend design consid ...
Thermal solar power plants using Rankine cycles closely approach the present economical electricity prices, at least in the large power range. One of the advantages currently explored is the integration with other fuel based technologies in order to ascert ...
