Collection description

This thesis work is aimed to evaluate the energy efficiency of HVAC plant solutions that exploit the low enthalpy geothermal energy of the ground. All this in order to provide a valid alternative for common building-system solutions (often not adequate to all climatic conditions) and thus to more easily made the complete self-sufficiency of the NZEB buildings and consequently the widespread diffusion of the Net/Plus ZEB in the near future. The thesis focuses mainly on the study of two components: 1- the Ground Source Heat Pump (GSHP), i.e., a heat pump which uses the ground as external source through buried probes. 2- the Earth-to-Air heat exchanger (EAHX), i.e., a system in which the outdoor air is pre-heated or pre-cooled trough buried pipes (in which there is a heat exchange between air and ground) to reduce the heating and cooling energy consumption in buildings. The present work first energetically analyses these two technologies separately, comparing them to more common alternative components. Lastly, the performance of these systems is compared with each other, in order to obtain an NZEB.
