Experimental research and analysis of energy efficiency for direct radiant floor heating system with ASHP
This paper presents experimental research and analysis of energy efficiency for direct radiant floor heating system with ASHP (air source heat pump). An experimental platform was built, and the performance of ASHP, heating effect and energy consumption of heating system were studied. The results show that the indoor heat load can be well met when the output capacity of ASHP runs at 30%, in which the floor surface temperature and indoor air temperature were reached at 26 °C, 22 °C, respectively. Vertical temperature field can well met the requirements of indoor thermal comfort. Besides, the paper examines heating performance for different envelope, the results indicate that as the condensing coil spacing decreases, the indoor heating effect gets better, but the consumption of energy and tubes increase. Finally, testing the hourly energy efficiency ratio of heating system, and comparing energy efficiency of different technologies, the results point out that radiant floor heating system with ASHP has the best energy efficiency and the obvious advantage of energy saving compared with other heating technologies.
