Energy and Exergy Analysis of a HVAC System having a Ground Source Heat Pump as Generation System

Paolo Valdiserri, Michael Lucchi, Marco Lorenzini

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 singlefamily dwelling located in the city of Rome, Italy. A firstand 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.
