摘要：
In this study, a new residential heat pump system was designed for domestic use in the geothermal dis-trict heating system (GDHS). A heat pump system was integrated into the substations of the residences with this aim. The heat pump system was formed by replacing the conventional evaporator with thermal energy storage (TES) unit. In this regard, a shell and tube latent heat TES system was used and designed for the peak loads. 66 different systems were parametrically formed and analyzed thermodynamically. The observed cases were later evaluated from economical and environmental points of view. Finally, the most appropriate system was determined by a multi-criteria decision-making analysis named effi-ciency analysis technique with output satisficing (EATWOS). It was concluded that it is available to obtain an investable design with an NPV value of 6.35 million $, exergy efficiency of 15.24% and CO2 reduction of 1435.32 ktons per year.(c) 2023 Elsevier B.V.
