Sandwich heat preservation type solar building integrated wall body

Abstract

The invention relates to a sandwich heat preservation type solar building integrated wall, mainly comprising a glass plate, a heat collection plate, a heat collection plate heat insulation layer, an outer bearing wall, a heat preservation layer, an inner bearing wall, a heat radiation plate, a circulating pipe I, a check valve, a control valve, an exhaust valve, a circulating pipe II and a connecting piece. The glass plate, the heat collection plate and the heat collection plate heat insulation layer are embedded in the outer surface of the outer bearing wall. The heat preservation layer is installed between the outer bearing wall and the inner bearing wall. The heat radiation plate is embedded in the inner surface of the inner bearing wall. The heat collection plate and the heat radiationplate are connected through the circulating pipes with the check valve, a control valve and the exhaust valve. The check valve and the control valve are used for controlling heat-carrying fluid to circularly flow in a closed loop formed by the heat collection plate, the circulating pipes and the heat radiation plate, solar heat is transferred to the indoor for heating in the heating season, indoor heat is prevented from being dissipated to the outdoor, and the heating heat load is saved. Outdoor heat can be prevented from entering indoors in the air conditioner season, and the air conditionercooling load is reduced.

Description

technical field [0001] The invention relates to a building-integrated solar wall, in particular to a building-integrated solar wall that can be used in prefabricated buildings, and belongs to the technical field of building-integrated solar energy. Background technique [0002] At present, construction, industry, and transportation have become the three main industries for energy use, among which the construction industry has the greatest potential for energy conservation. In my country, building energy consumption accounts for more than 27% of all energy consumption, and it is increasing at a rate of 1% per year. In building energy consumption, heating and air conditioning consume the most energy, accounting for more than 60% of the overall proportion. In the global energy consumption, 45% of the energy is used to meet the requirements of buildings for heat removal, cooling and lighting, and 5% is used for the construction process of buildings. Reducing building energy con...

Problems solved by technology

However, in current practical engineering applications, most solar wall systems are combined with single-layer materials as units, which cannot fully guarantee the beauty of the building. At the same time, the wall may occupy too much space, reducing the building structure. assembly efficiency
