یک سیستم جدید گرمایی، خنک کننده و سیستم آب گرم خانگی زمین خورشیدی: شبیه سازی پویا و تجزیه و تحلیل انرژی-اقتصادی

A 1-year simulation is performed and the system performance is analyzed with daily, weekly and yearly time bases. The system analysis is completed with a sensitivity analysis, performed in order to evaluate the system energy and economic profitability as a function of the solar collector field area. The results outline that geothermal and solar energy are only used to match the thermal demand of the district users during winter, while only during summer the activation of the auxiliary biomass boiler is mandatory to match the space cooling demand. The novel system achieves a satisfactory yearly performance in terms of solar collector field efficiency (above 40%) and adsorption chiller Coefficient of Performance (0.5). The system is not economically feasible without any public funding (Simple Pay Back of 20.9 years), while a significant primary energy ratio is achieved (above 75%). In case of public funding policies, the Simple Pay Back period can be halved.
