چکیده انگلیسی
To reduce the energy consumed by ventilation in a building is a critical task for the related researchers. Using the solar chimney effect to obtain the nature ventilation at day time is possible. Here a hybrid wall with PCM was provided, and the effect of the position of PCM in the hybrid wall on the solar chimney effect was studied. The thickness of PCM was 1cm, the air gap was 30cm and the power of the simulation solar light was 780W. The results show that when PCM was in front of absorber, the temperature of the air in the gap was higher than that of the air with a PCM behind the absorber. As for the air velocity in the gap, when the simulation solar light was turn on, the air velocity with PCM in front of the absorb was higher than that of the air with PCM behind the absorb. While when the simulation solar light was turn off, the air velocity with PCM in front of the absorb was lower than that of the air with PCM behind the absorber It is interesting to guide the construction of the hybrid wall.
