Problems solved by technology

However, the current solar chimney technology only utilizes a single solar energy to realize thermobaric ventilation, and the treatment at the air outlet of the solar chimney is also quite simple, so that the system is greatly affected by outdoor climate conditions and has great limitations: For example, when the outdoor wind speed is high and the wind speed direction is facing the air outlet of the chimney, the air flow will be reversed; in addition, most of the heat collectors used in solar chimneys are flat surfaces, which have poor heat collection effects and heat exchange with the air. not obvious wait

Abstract

The invention discloses a modified solar chimney system which comprises a transparent glass cover plate, a solar collecting panel mounted on a outer wall facing the south, an air passage formed between the transparent glass cover plate and the solar collecting panel, and wind guide rotating exhaust hood disposed at the top of the air passage. A plurality of longitudinal ribs protruding towards the air passage are disposed on the solar collecting panel, so that solar collecting area is increased effectively, more solar radiation can be absorbed, and heat exchange effect between the air and the solar collecting panel can be intensified by the longitudinal ribs.

Description

technical field [0001] The invention belongs to the technical field of passive buildings, and in particular relates to an improved system using a solar chimney to enhance ventilation technology. Background technique [0002] At present, with the rapid development of the economy and the continuous improvement of people's living standards, the proportion of building energy consumption in the total energy consumption of society is getting higher and higher; therefore, in today's global energy shortage, we must pay attention to the construction field Advanced energy-saving technologies, and actively advocate the concept of ecological energy-saving buildings, using clean and renewable energy to achieve sustainable development of human beings. [0003] In recent years, solar chimneys have attracted more and more attention as a method of using thermal pressure to strengthen the natural ventilation of buildings, and have become a hot spot in the field of energy-saving building resea...
