Photo-controlled, Temp,-controlled semi-automatic hidden rolling apparatus for building with solar energy

Abstract

The invention belongs to building energy saving and new energy resource utilization technique field. It is semi-automatic built-in roller shutter device used in light and temperature control of the solar building. Its features are introducing the special curtain in common building into passive form solar building; improving it to set the roller shutter in the air space of the solar building heat collection wall. Its advantages are that rolling the shutter according to outdoor meteorological and indoor thermal environment parameter and cooperating with hand pull rope. The control end is set display panel. Its power source is supplied by solar energy photocell. The user can directly see the roller shutter control state and indoor temperature parameter. The roller shutter can preserve heat in winter, shade sun in summer.

Description

technical field [0001] The invention belongs to the technical field of building energy saving and new energy utilization, and is a building component of a passive solar building. Specifically, it relates to a semi-automatic built-in roller blind device for light control and temperature control used in solar buildings. Background technique [0002] Passive solar buildings are mainly used for heating in winter, and its heating effect has been generally recognized. However, recent studies have found that at night in winter, if the south-facing heat-collecting wall is not insulated, the heat loss will be greater, which is not conducive to its heat collection during the day. As early as 1991, W.Smolec once proposed the concept of adding thermal insulation roller blinds in the air interlayer of the heat collecting wall, but did not involve its specific application. In the same year, Lu Bingwei proposed a manually controlled passive solar house insulation board, but this insulati...

Problems solved by technology

In the same year, Lu Bingwei proposed a manually controlled passive solar room insulation board, but this insulation board is not suitable for high-rise buildings and urban multi-storey houses

[0003] At the same time, the better the heating effect of passive solar buildings in winter, the more serious the problem of overheating in summer: the transparent covering used in traditional heat collecting and storage walls has a blocking effect on infrared radiation, so that the heat collecting walls absorb too much heat during the day. The sun radiates heat and stores it in the wall. At night, this part of the heat is transferred into the room through heat conduction, causing the room temperature to rise and overheating.
