Thermal System Analysis

The performance of an innovative floor heating application is explored. A two zone building is studied; one zone is frequently overheated due to intensive solar gains while the second zone is essentially unaffected from incident solar radiation. The aim is to explore the possibility to simply extract excess heat from the overheated zone. The idea is to transfer extracted heat through the hydronic floor heating pipe to the second zone; hence, the heat demand for the second zone is decreased. Simulation results yielded a reduced indoor air temperature in the warm zone.
