Embodiment Construction

[0025] First of all, it is stated that the buildings mentioned in this application are all buildings on the northern hemisphere of the earth, so the south facing wall is the wall facing the sun.

[0026] Such as figure 1 , figure 2 As shown, the passive solar greenhouse provided by the present invention is to build a heating room 20 on the south wall 11 of the building 10, and the south wall 20 of the heating room 20 is a daylighting wall 21 (preferably made of flat glass) into), and the angle between the lighting wall 21 and the vertical line is 23-35 degrees (preferably 30 degrees).

[0027] According to the transmission theory of solar energy, it can be seen that the sun mainly transmits its heat to the earth's surface and its buildings 10 in the form of light radiation, and only when the solar radiation light is perpendicular to the surface receiving the light, the building 10 In order to receive maximum heat. In the present invention, the angle between the lighting wa...

Abstract

The invention provides a passive solar greenhouse. A heating room is built on a south wall of a building; the south wall of the heating room is a lighting wall, and the included angle between the lighting wall and a plumb line is 23-35 degrees. According to the invention, the included angle between the lighting wall of the heating room and the plumb line is set to be 23-35 degrees which is just a solar incident angle (also named as solar elevation angle) at 12:00 a.m. on the day of Great Cold in a northern latitude 45-35 degree region (a region with the richest solar energy in China) and is close to the solar incident angle at noon within coldest 45days from the midwinter to the spring begins (the coldest days of the year) in the northern region. Namely, the solar radiation ray at the moment can be approximately-vertically irradiated to the building so that the building can receive solar hot energy to the greatest extent within the coldest time period.

Description

technical field [0001] The invention relates to a passive solar energy warming structure, which is suitable for small buildings with two or more floors in new rural areas of my country, and plate-type multi-storey buildings in cities and towns. Background technique [0002] Generally, buildings that use solar energy for heating or air conditioning are called solar greenhouses. Solar greenhouses can be divided into two categories: active and passive. A passive solar conservatory is a building that lets sunlight into a house and uses it naturally. It does not require additional solar heating mechanical equipment systems (collectors, pipes, etc.), and the entire building itself is a solar thermal collection system. It is energy-saving and environmentally friendly, and is deeply loved by people. [0003] At present, there are three heating methods of passive solar greenhouses in China: direct benefit type, heat collection and heat storage wall type, and additional sunlight ro...
