Proposes a new type of porous heating vertical panel, which has the characteristics of flexible regulation, fast thermal response, space saving and good sanitary conditions. Builds a full-scale experimental system about the new structure in a laboratory, and tests the radiation and convection heat transfer characteristics, indoor thermal environment distribution under the conditions of different supply water temperatures, orifice diameters and orifice densities. The results show that, in respect of the panel heating capacity, the supply water temperature plays the most important role, followed by the orifice diameter and orifice density. The convection heat transfer effect caused by the stack effect pressure of the top and bottom orifice air is obvious, and the maximum orifice air speed can reach 0.12 m/s.The radiant vertical panel creates a relatively uniform indoor temperature in both horizontal and vertical directions.
