Abstract

This study analyzes the effect of applying a Heat Spreader Plate (HSP) to a wet floor structure on heat transfer performance and required supply water temperature. Under outdoor reset and indoor temperature feedback control, both Standard and HSP structures maintained similar indoor temperature and heat flux, while the HSP required a lower supply water temperature. The results indicate that the supply water temperature should be determined according to the floor panel structure, and that HSP application can reduce the required supply water temperature.
