Abstract:
According to the characteristics of the climate and distribution of solar resource in Chongqing, the technology idea of integrated application of solar energy and building is proposed, which is suitable for Chongqing area, i.e. solar assisted indoor ventilation cooling measure, which takes full advantage of the strong solar radiation in summer and strengthens the “chimney effect” to promote natural ventilation inside the building, improve the summer indoor hot and humidity environment, save energy and achieve solar energy passive using. Experiments and analysis show that the 0.16~0.22 m/s indoor air speeds are produced by the thermal effect of solar energy, which is increased by 14%~40%. And the average indoor temperature is 2.6~3.4 ℃ lower than the outdoor average temperature, and the indoor thermal comfortable state is effectively improved.
