Desiccant-based air handling units (AHU) can allow significant energy saving and emissions reductions with respect to conventional air-conditioning systems. In this work, experimental tests are used to investigate a hybrid desiccant cooling system (DCS) with desiccant wheel (DW), interacting...

Co-digestion, pretreatment and digester design are the key techniques for enhanced biogas optimization. Co-digestion dilutes the inhibitory effects of substrates, balance the micro and macronutrients, increase the organic loading with consequent higher methane yields per unit of digester volume;...

Thermo-compressors are widely used in industries for steam compression through a thermal process. Common methods of thermo-compressors analysis are based on the hypothesis of considering steam as a perfect gas. In this study, the deviation of thermo-compressor performance at wet steam conditions...

In the present work, performance of new configuration of Micro-gas turbine cogeneration and tri-generation systems, with a steam ejector refrigeration system and Heat recovery Steam Generator (HRSG) are studied. A micro-gas turbine cycle produces 200 KW power and exhaust gases of this micro-gas...

The paper reviews the different economic potential of the ten analysed CEE countries at the beginning of the transformation process (1989 - 1990). The main features of each transformation approach are identified (privatization, liberalization, transition between economic systems). A comparative...
