Experimental study on the thermal performance of an enhanced-convection radiative heating wall system

Abstract This paper proposes a novel enhanced-convection radiant heating wall system, which uses enhanced-convection technology while retaining the advantages of traditional low-temperature radiation heating. Experimental study on thermal performance of radiant heating wall with different water temperature, hole diameter, hole density was conducted in the artificial climate room. The experimental results show that as the pipe water temperature increases, the average surface temperature and heat flux density of the panel increase, the average surface temperature response is faster; as the hole diameter and hole density increase, the average surface temperature of the panel increase; natural circulation caused by hot pressure is formed between the air in the interlayer of the radiant heating wall and the indoor air, and as the pipe water temperature increases, the air velocity at the ventilation hole gradually increases, but the average air velocity at the ventilation hole is less than 0.15 m/s, which can meet the thermal comfort of the human body.
