摘要: Abstract Owing to the relatively limited efficiency of separate power, heating and cooling production systems, multi-generation (combined heat and/or cooling) has drawn a lot attention in recent years. The design multigeneration systems based on Organic Rankine Cycle (ORC) adsorption is appealing, since these technologies can utilize medium low temperature including waste solar energy. In present work, study four potential system configurations an integrated - cycle carried out. For given source, first second law efficiencies investigated are calculated for number organic fluids considering subcritical supercritical ORC. Furthermore, optimized taking into account pinch point values exchangers. A zeolite-water chiller considered with nominal capacity 13 kWc. results each configuration compared that ORC Vapour Compression (VCC) same capacity. highest exergetic ORC-adsorption ORC-VCC equal 40% 30%, respectively.
