Abstract
This study aims to compare characteristics of indoor environment and energy consumption of multiple radiant heating modes as well as their combination in winter. A simulation software, EnergyPlus, was used in this study. An office room model based on a real room which was located in Changsha, China, was established. Several radiant heating models with different radiant surfaces and their combinations were selected for simulation. Besides, two conventional heating modes were selected as comparisons, i.e. split air conditioning system and fan coil + fresh air system. In order to compare energy consumption of different systems under a similar condition, PMV = 0 was set as the indoor set-point of all heating systems in this study. A detailed analysis on all heating systems was conducted on the winter heating design day. The obtained results indicated that the system of radiant ceilings, side walls and floor is the best combination. This study provides references of selecting different radiant heating modes for thermal comfort and energy efficiency in winter.
