EVALUATION OF THERMAL COMFORT AND ENERGY CONSUMPTION IN A ROOM WITH DIFFERENT HEATING SYSTEMS

Indoor thermal environment is much affected by characteristics of an equipped heating system. Suchthermal environmental factors as temperature, air velocity, radiant temperature and their distributionscan influence the thermal sensation and the energy consumption of a heating system. Quality ofthermal environment can depend on a heating system installed.In this study, differences between a floor heating system and a wall-mounted air conditioning unit areinvestigated in terms of the thermal sensation and the energy consumption using the coupledsimulation of convection-radiation-thermoregulation. A human body model precisely reproducingfeatures of a male adult is positioned on the floor in the leg-out posture. The thermal sensation of thewhole body with different heating systems is assumed to be equal as long as heat release from thehuman body is the same. Subject experiments are also conducted in a room within a climate chamberunder the same conditions as the simulation. Results of simulation and experiments are compared interms of thermal comfort and energy consumption.
