Multifunctional shutter-type solar heat collecting system

Abstract

The invention discloses a multifunctional shutter-type solar heat collecting system. Solar heat is absorbed through a shutter-type solar heat collecting integrated board to be utilized, and a temperature difference is generated between two sides of the system by adopting a solar cell panel penetrating the system side and using glass with different heat transfer coefficients, so that the heat convection capacity is generated, the ventilation effect is improved and the energy required for ventilation is reduced. The efficiency of a product is greatly improved, the service life is greatly prolonged, in addition, the energy consumption required for building ventilation is also reduced, and heat exchange of a building and the outside is reduced, thereby achieving the economical and energy-saving effects.

Description

technical field [0001] The invention relates to the technical field of solar heat utilization and building energy saving, in particular to a solar heat collection device for a thermal convection window and an automatic control system for light-to-heat conversion. Background technique [0002] People's energy consumption is increasing day by day, and our country is also facing the danger of energy shortage. In terms of energy consumption, the energy consumption generated during the construction and use of buildings accounts for 53.6% of the total global energy consumption, and the heat loss of windows accounts for 40-50% of building energy consumption losses. The heat exchange between the windows of the building and the outside will lead to an increase in building energy consumption. [0003] The use of double-layer glass can reduce the building energy consumption caused by the heat exchange between windows and the outside world, and the sound insulation effect is good, whic...

AI Technical Summary

Problems solved by technology

At present, public buildings such as office buildings mostly use large floor-to-ceiling windows, and curtains are generally not used for shading in public areas of buildings. Due to the large area of ​​windows and no curtains, building energy consumption is higher

Light pollution is common in high-rise office buildings, that is, high-rise office buildings and other building curtain walls will reflect sunlight to other places, resulting in light pollution

When there is no wind outside, it is difficult to form air convection with open windows. At this time, the air circulation of large buildings depends on fans, which will increase the energy consumption of buildings.

[0004] Solar heat collection has the advantages of energy saving, cleanness, sustainable use, and wide distribution. However, traditional solar heat collection has uncontrollable photothermal conversion efficiency and fixed installation angle of the collection device, which cannot meet the optimal working conditions; when the light is too strong, Hot water is easy to boil in the heat collection device, causing explosion hazard; solar heat collectors are generally located on the top floor of the building, and after snowfall, the heat collection plate will not receive sunlight and the system will stop heat collection; at the same time, solar water heaters also require additional Installation, takes up extra space, is not easy to clean, and the heat collection efficiency is declining year by year
