To solve the drawbacks of the traditional Trombe wall

such as a lag of air heating during the daytime and heat transfer from hot wall to outside at night

this paper presented a newly designed Trombe wall with the solar energy absorber inside the interlayer. The temperature variation and thermal performance of the Trombe wall were analyzed quantitatively by measuring the temperature and solar radiation intensity in the experimental room and control room with the outdoor environment. The experimental results were obtained by analyzing the data of three typical outdoor environment days in a row. The results indicated that the maximum temperature difference between the experimental room and the control room was 3.3 ℃. In the experimental room

the maximum and lowest temperatures were 24.1 ℃ and 12.9 ℃ respectively with the average temperature of 18.4 ℃

and the maximum temperature of the air supply was 31.6 ℃. The increase rate of air temperature in the experimental room reached 1.4 ℃/h under the average solar radiation intensity of 438.4 W/m2. Within 52.8% of the total time

the temperature in the experimental room was above 18 ℃ according to the indoor temperature frequency distribution. The experimental results showed that the heat gain can be timely delivered to indoor during the daytime

and can maintain a certain level in the night. Therefore

human body will feel comfortable all day due to the control of the indoor temperature range and the indoor environment could be improved effectively when using this novel Trombe wall.
