Experiment of operating modes for direct floor panel heating systems with air-source heat pumps

Studies the heating performance of the systems with digital scroll air-source heat pumps by experiment. Tests the indoor air temperature, surface temperature of building envelope, floor surface temperature and electric power consumption under continuous and intermittent operating modes. Analyses and compares the indoor thermal environment and energy consumption in the two modes by introducing the operative temperature. The result shows that the continuous operating mode can create an ideal thermal environment but with a larger amount of electric power consumption, while the intermittent operating mode can well satisfy the demand of the thermal comfort and reduce energy consumption remarkably for certain residences.
