Abstract

To solve the problems of low heating efficiency of traditional Trombe wall in winter and overheating in summer, an high-efficient dual-channel Trombe wall system was proposed. The thermal performance and the heating effect of the system in winter was experimentally studied. The results show that the thermal efficiency of the high efficiency dual-channel Trombe wall is 1.6-3.4 times higher than that of the traditional Trombe wall. The indoor temperature is increased by 0.7-5.7 ℃ compared with the traditional Trombe wall. When the total channel thickness is 0.5 m and the outer channel thickness is 0.2 m, the thermal efficiency of dual-channel Trombe wall with U-shape baffle reaches the highest of 31%. And the indoor temperature can reach up to 21.7 ℃. The heat transfer model of high efficiency dual-channel Trombe wall is established on the basis of experimental research, and its accuracy is verified, which can provide foundation for further optimization.
