In this paper, a performance analysis on the basis of a simulation model and experimental data of a 1kW High Temperature PEM (HTPEM) cogeneration system is presented. The system is composed of a steam reforming unit that can be operated with natural gas. The balance of plant is modeled using a...

In this paper, the efficiency of one full charging and discharging cycle of several adiabatic Compressed Air Energy Storage (CAES) configurations are analyzed with the help of an energy balance. In the second step main driving factors for the efficiency of the CAES configurations are examined...

The increase in the power of photovoltaic systems involves a significant grow in the number of modules that make them up. The known problems caused by the shading are not usually taken into account in the design of a photovoltaic central away from urban environments. The aims of this study are...

A simulation model has been developed in this paper to predict the performance of greenhouse that is heated with a heat-pipe system. The model is validated with experimental data and is found to be in close agreement. The simulation can provide estimations of the influence of the maximum height,...
