Abstract: This study presents a novel concept to provide space heating and cooling inside buildings using a thermal distribution network. The thermal network consists of a single-pipe loop circulating two-phase CO2 as the heat carrier fluid and connects all the thermal zones together. It offers simultaneous heating and cooling in buildings as well as heat recovery between the zones. The proposed system with all its associated components were modelled using MATLAB and hypothetically applied in small office buildings in three cities with known yearly load profiles. Consequently, the annual performance of the thermal network was evaluated for those offices and showcased the high potential of this novel system for buildings with simultaneous heating and cooling demand in mild climate regions.
