Porous permeable fresh air preheating solar wall

Abstract

The invention discloses a porous permeable fresh air preheating solar wall, which includes a heat collection and storage system and an airflow delivery system; the heat collection and storage system includes a solar wall panel, and a Air interlayer; the top of the solar wall panel is provided with an air chamber connected with the air interlayer, and an air outlet is provided on the outer wall of the air chamber, and a movable device for adjusting the opening of the air outlet is installed on the air outlet. The deflector; the air intake holes are distributed on the solar wall panel, and the outer wall of the solar wall panel is provided with a heat-absorbing coating; the outer wall of the solar wall panel is provided with a shading device; the air delivery system It includes a fresh air duct, on which a damper and an axial flow fan are installed, an air outlet is arranged on the side wall of the fresh air duct, and one end of the fresh air duct communicates with the air cabin. The invention can not only obtain fresh air in winter but also maintain a suitable indoor temperature, which can not only meet the requirement of energy saving but also meet the requirement of indoor air quality.

Description

Technical field [0001] The invention belongs to the field of solar thermal utilization and building heating, and specifically relates to a porous and permeable fresh air preheating and heating integrated solar wall system, which is used for winter fresh air preheating and indoor heating of classrooms, office buildings, etc., and mainly solves large-area window opening in winter Difficult, poor indoor air quality and other practical problems. Background technique [0002] my country's building energy consumption accounts for about a quarter of the total social energy consumption, of which heating and air conditioning energy consumption accounts for 40% to 50% of building energy consumption. Solar energy is an inexhaustible and inexhaustible clean energy. Therefore, using solar energy to improve the indoor thermal environment of buildings can effectively reduce conventional energy consumption. [0003] The cold wind penetration heat load is the main part of the heating load in winte...

AI Technical Summary

Problems solved by technology

[0004] At present, many scholars have done a lot of in-depth research on the commonly used direct benefit windows, heat collecting and storage walls, and additional sunlight room passive solar technologies. The results show that these passive solar heating technologies can effectively increase indoor temperature and reduce heating heat in winter. load, but these technologies are difficult to take into account the improvement of indoor air quality in winter

Although the existing fresh air heat recovery, preheating and other systems can improve indoor air quality, the equipment system is more complicated and the investment is higher
