Thermal Performance of Thin Type Radiant Floor Heating Combined with Fan-coil Heating

An experimental room was setted up for the heating system as research object, the heat source is air-source heat pump, the extreme is thin type radiant floor heating system combined with fancoil heating system. The floor heating temperature and thermal performance under stable conditions are researched. The electricity consumption of fan-coil heating, radiant floor heating and radiant floor heating with fan-coil were analyzed through the data recorded by the meter. The value of the COP under three ways were compared after the calculation. Results indicate the indoor temperature response speed of the combined heating system is fast. Within the scope of the indoor temperature requirements, the average floor surface temperature is appropriate with less electricity consumption, the combined heating system is more energy-saving and more comfortable.
