摘要: Abstract The purpose of this study is to investigate geothermal heat pump aided district heating for a town center with population nearly 25,000, from the exergy and economic points view. By way, different working fluids in number 12 were investigated find optimum solution system coupled which resources Simav region directly used shell tube type exchanger. In aim, parameters such as temperature pressure using energy analysis taking 4686 designs into consideration. obtained results these then evaluated aspects. For best solution, most was revealed handling Life Cycle Cost ( LCC ) concept Net Present Value NPV analysis. It found that it has been possible residences between 7929 46,098 values changing between −1192.81 23.20 million US$. As result, 13,776 could be heated by proposed system. So, pre-feasibility shows usage would an attractive investment region.
