摘要
Taking the comparable hot box as the experimental platform, a photovoltaic Trombe wall experimental system combined with phase change materials (PV-PCM-Trombe) was constructed. Its building thermal environment and photoelectric performance were analyzed through the winter working test. The main research results are as follows: the temperature in the experimental room is always higher than that in the comparison room and the ambient temperature, and the higher the average daily ambient temperature, the greater the temperature difference comes, indicating that the system can efficiently use solar energy to achieve good passive heating effect in buildings in winter; phase change panels absorb solar energy during the day to store heat, which can keep the room warm for a longer time in the winter night. During the experiment, the average photoelectric efficiency of the system is about 13.71%, and there is a strong correlation between the photoelectric efficiency and the open circuit voltage.
