This study reports on a dynamic simulation of the annual performance of a HVAC system consisting of a ground coupled heat pump (GCHP), which has which has a ground heat exchanger with horizontal pipes for winter and summer seasons. The simulations are performed by employing the software Trnsys. The HVAC system is connected to a thermal storage tank containing warm water in winter and cold water in summer, which serves a single-family dwelling located in the city of Rome, Italy. A first- and second-law analysis of the yearly performance of the entire system and of the single components was carried out, highlighting the components with the lowest exergy efficiency.

Abstract

This study reports on a dynamic simulation of the annual performance of a HVAC system consisting of a ground coupled heat pump (GCHP), which has which has a ground heat exchanger with horizontal pipes for winter and summer seasons. The simulations are performed by employing the software Trnsys. The HVAC system is connected to a thermal storage tank containing warm water in winter and cold water in summer, which serves a single-family dwelling located in the city of Rome, Italy. A first- and second-law analysis of the yearly performance of the entire system and of the single components was carried out, highlighting the components with the lowest exergy efficiency.
