This paper presents the numerical simulation of an efficient ammonia-water single-stage absorption chiller integrating a new combined desorber, able to produce and purify refrigerant vapor. An experimental campaign was conducted on pilot plant by varying main operating parameters, namely temperatures external sources mass flow rate working fluid. Direct measures were analyzed indirect calculati...

The aim of this scientific research is to experimentally determine the exergy losses a ground heat pump and further optimization for more efficient use operating modes improvement individual structural elements. In addition, it proposed photovoltaic panels as backup power source experimental installation under study. exergetic are calculated, not only itself, with R407C refrigerant. methodology...

Exergy analysis is based on combined first and second laws of thermodynamics and is a useful tool to analyze the energy systems in a better and more realistic way than an energy analysis, based on the first law of thermodynamics. Combination of exergy from thermodynamics with conventional concepts from engineering economy which is referred to as thermo-economy (exergo-economy) is a valuable too...

An innovative biomass gasifier integrated plant was proposed for combined heating and power production in the current paper. The consists of an s-CO2 cycle, gasifier, combustion chamber, a domestic water heater purposes. system studied from different perspectives, i.e., energetic, exergetic, exergo-economic, economic, environmental (4E). For this purpose, simulation carried out by EES software;...

Combined heat and power systems are becoming more and more important, regarding their enhanced efficiency, energy saving, and environmental aspects. In the peresent study, three configurations of combined heat and power systems are intended as an alternative to separate production plant by considering environmental aspects. First and second laws of thermodynamics are adapted to the operatin...
