technical field

The invention relates to a wind-heat-pressure-induced multi-channel ventilation and heat insulation system, which belongs to the technical field of ventilation equipment for residences and public buildings, and specifically relates to a wind-heat-pressure induction effect that effectively utilizes two renewable energy sources, solar energy and wind energy. The multi-channel ventilation and heat insulation system with extremely remarkable energy-saving effect can ensure the indoor air quality without consuming electric energy while providing natural ventilation.

Background technique

With the development of building technology and the increasing scarcity of non-renewable energy sources, the problem of high energy consumption in buildings has become increasingly prominent, and the proportion of building energy consumption in total energy consumption is also increasing. In developed countries, nearly 40% of energy is consumed in buildings; in my country, building energy consumption accounts for about 1/3 of the total energy consumption of the whole society. With the continuous advancement of my country's urbanization process and the continuous improvement of living comfort standards, if the development model of developed countries is followed, building energy consumption will increase significantly. Therefore, the development of advanced building energy-saving technologies and the effective and rational use of renewable energy such as solar energy and wind energy to reduce building energy consumption are of great significance to the energy-saving of the entire society.

Natural ventilation in buildings is of great significance to the guarantee of indoor thermal comfort and indoor air quality. Using renewable energy to achieve natural ventilation in buildings is an effective measure for building energy conservation. Solar chimneys are a common method of using solar energy to form natural ventilation. Based on the effect of solar thermal pressure, heat energy is converted into kinetic energy, and the buoyancy force generated by density difference is used to provide power to realize natural ventilation of buildings. There are three types of traditional solar chimneys: Trombe wall structure, vertical structure and inclined roof. Patent 201320748851.5 discloses a greenhouse for ventilating and drying crops using solar interlayers. A solar panel system and fan system are installed on the basis of traditional solar chimneys for ventilating and drying crops. Patent 201410063784.2 discloses a Trombe wall with comprehensive application of solar heat collection and radiative cooling. A venetian blind is added to the traditional Trombe wall. One side is coated with a selective absorption coating and the other side is coated with a selective radiation coating. , using the difference in emissivity and absorptivity of the two coatings in different wavelength bands to achieve cooling or heating.

Traditional solar chimneys can enhance the natural ventilation of buildings through thermal buoyancy, but there are still deficiencies, as follows: (1) The actual solar chimneys will inevitably be affected by wind force, and even the wind force will affect its performance. Weakening and inhibition, the traditional solar chimney does not consider the influence of the outdoor wind speed, nor does it effectively and rationally utilize the effect of the outdoor wind; (2) The ventilation form of the traditional Trombe wall structure sets an air channel, and its heat-absorbing part is set on the outer wall of the building , The heat insulation effect is not good, which increases the indoor cooling load. The traditional solar ventilation system uses solar energy only on the heat absorbing layer, and the solar induction ability is insufficient; (3) Although the solar ventilation system using solar panels and fans does not consume other forms of energy, it involves more circuit components, equipment and investment, and the system Complexity, maintenance and repair difficulty increase.
