A high-rise building solar thermal collection and utilization system

Abstract

The invention discloses a solar photo-thermal acquisition utilization system of a high-rise building. The system comprises a concave reflecting mirror, a reflecting plate, at least one light conducting barrel or at least one light collecting channel and at least one acquisition end, wherein the concave reflecting mirror is arranged at the top of the building; the reflecting plate is arranged in a light collecting area of the concave reflecting mirror; a reflecting light ray of the reflecting plate is aligned with the light conducting barrel or the light collecting channel; a reflecting sheet is arranged in the light conducting barrel or the light collecting channel; the reflecting light ray of the reflecting sheet is aligned with the acquisition end; the acquisition end is arranged in a household kitchen, a bathroom or other indoor rooms; and an acquisition channel which corresponds to a reflecting direction of the reflecting sheet is arranged at the acquisition end. The system provides solar light energy for each family by using a concentrated mode of the light conducting barrel or the light collecting channel, so the defects that the conventional solar water heater is difficult to install, the energy loss of hot water in a pipeline is large and bottom-floor households cannot use solar energy are overcome, and the concentrated supply mode of the solar light energy is elegant and cannot influence external walls of the building.

Description

technical field [0001] The present invention relates to a solar light and heat collection and utilization system, specifically a solar light and heat collection and utilization system installed on a high-rise building, which can concentrate the sunlight on the roof of the building and send it to the Each household uses it, and the excess is sent to the hot water storage tank or solar battery array at the bottom of the building. Background technique [0002] With the transformation of the international and domestic energy situation, the increasing shortage of traditional energy will inevitably lead to the rapid rise of the new energy industry. It is an inevitable development trend that solar clean energy partially or completely replaces traditional energy. Solar energy is divided into narrow-sense solar energy and generalized solar energy. Narrow-sense solar energy refers to the thermal radiation energy directly radiated from the sun to the earth's surface; generalized solar ...

Problems solved by technology

[0003] Compared with traditional energy, solar clean energy has the advantages of huge supply, clean and safe, and little pollution. The solar radiant energy reaching the earth every year is about 13 trillion tons of standard coal, which is equivalent to 2×104 of the world's annual energy consumption times; the sun is shining, and solar radiation can reach any area on the earth's surface; however, solar energy also has many shortcomings: 1) low energy density, although the total amount of solar energy is huge, the solar energy obtained per unit area of ​​the earth's surface is very limited

In winter, the above value will drop by half, and it will drop by 4 / 5 in cloudy days; 2) The supply is unstable, and the supply of solar energy changes with day and night, seasons, and cloudy or sunny, and is extremely unstable

3) The cost of solar energy utilization system is high and the efficiency is relatively low

[0006] Now my country's urbanization is developing at a high speed. In metropolises, there are row upon row of high-rise buildings, and the buildings are getting taller. In order to increase the lighting rate and ventilation of each household, most buildings adopt the method of lighting channels. , but because the building is too high, the lighting effect of the lighting channel is very poor. At the same time, the lighting channel has become a shared area, which increases the cost of purchasing a house for residents

And because after the building is built high-rise, it is difficult for people to use solar energy
