Problems solved by technology

Solar radiation contains both light and heat. In the heating season in the north, there is a huge difference in indoor temperature between the south and north of the building. The current method is mainly to use natural light or heat alone, and it lacks the simultaneous full use of solar radiation light and heat.

Embodiment 1

[0048] In an exemplary embodiment disclosed in this application, there is provided a lighting and heating device that uses mirrors to automatically track and directional reflect sunlight, such as figure 1As shown, a lighting and heating device that utilizes mirror surface automatic tracking and directional reflection of sunlight includes: a support; a pitch angle adjustment device fixed on the support; a mirror frame 16 installed on the pitch angle adjustment device; a mirror 17 fixed On frame 16. The angle of the mirror frame 16 can be adjusted by the pitch angle adjustment device, so that the mirror surface can adjust the reflection angle according to the sun angle change, and adjust the reflected sunlight to the desired orientation in time.

[0049] Specifically, the mirror 17 has several pieces, and the mirror 17 is a plane mirror. Described pitch angle adjustment device comprises: pitch angle adjustment device, is fixed on the described bearing; Horizontal pitch angle ad...

Embodiment 2

[0054] Apply the lighting and heating device of this application that uses mirror automatic tracking and directional reflection of sunlight in building groups. Specifically, it is installed on the exterior wall of the fourth teaching building to reflect solar radiation to the northern room 318 of the second teaching building in front. . Monitor the temperature and illuminance of the three rooms 222, 318, and 416. Monitoring results such as image 3 with Figure 4 As shown, the reflected light enters the 318th room, both the temperature and the illuminance are significantly higher than the other two rooms. The temperature and illuminance of the two rooms 222 and 416, which are not illuminated by reflected light, are relatively stable without obvious fluctuations. The illuminance of the room irradiated by reflected light will fluctuate greatly with the intensity of sunlight. It shows that the device of the present application has greatly improved indoor heating and lighting....

Abstract

The invention provides a daylighting and heating device for automatically tracking and directionally reflecting sunlight through a mirror plane. The device comprises a support, an angle adjusting assembly comprising a first angle adjuster and a second angle adjuster, a mirror bracket and a mirror. The daylighting and heating device for automatically tracking and directionally reflecting sunlight through the mirror plane is simple in structure, low in manufacturing cost and precise in positioning, the sun angle is automatically calculated through a program, the pitch angle and the horizontal azimuth angle of the mirror plane are automatically adjusted through a controller, the sunlight is directionally reflected into interior architecture in order to increase the indoor temperature and illuminance of a building, and the device is suitable for being widely popularized in building groups.

Description

technical field [0001] The present application relates to the technical field of solar energy equipment, and in particular to a lighting and heating device that utilizes mirrors to automatically track and directionally reflect sunlight. Background technique [0002] Solar energy is a clean and renewable energy. Solar water heaters, solar photovoltaic power generation, and solar heating are typical utilization methods. Among them, solar hot water and solar photovoltaic power generation technologies are relatively mature, but traditional solar heating methods have complex systems and low utilization efficiency. low and insufficient utilization of solar radiation on the south facade of the building. [0003] In some large solar power plants abroad (such as the Nevada No. 1 solar concentrating tower project in the United States), solar energy is concentrated, and the turbine is driven to generate electricity through solar heat. There are similar test systems in China, but the a...
