Respiration type construction energy-saving structure

Abstract

The invention discloses a building energy-saving structure. At least one part of an outer wall body is a sandwich wall; the lower part of an outer wall of the sandwich wall is provided with an air inlet, while the upper part is provided with an exhaust outlet; and a height difference which can form heat pressure is reserved between the air inlet and the exhaust outlet. When the heat pressure is inadequate, a heat collection tube can be arranged on a roof, and circulating water used to heat the air which passes through the exhaust outlet is filled into the heat collection tube. Two air openings are arranged in a respiration type energy-saving roof, the lower air opening is used for air inlet, the higher air opening is used for air exhaust, and a height difference which can form the heat pressure is reserved between the two air openings. The building energy-saving structure has a simple structure and low cost, and can guarantee the strength of a building. In summer, all the air openings are opened, the air enters the lower air opening, and flows out from the exhaust outlet and quickly takes heat away due to the fact that the height difference of the air inlet and the air exhaust forms the heat pressure, and the load of the building is decreased; in winter, the air inlet and the exhaust outlet are closed, the sandwich wall and the roof become thermal insulating layers and play a role of heat insulation, thereby having the effects of being warm in winter and cool in summer.

Description

technical field [0001] The invention relates to buildings, in particular to energy-saving design on buildings. Background technique [0002] Energy saving and environmental protection are the themes of today's world, not only related to the national and government organization levels, but also closely related to the lives of each of us. In the construction industry, including various buildings, especially residential buildings and office buildings, the requirements for energy saving are more clear. At present, the requirements for maintaining the heat transfer coefficient of structures have become industry norms. In the construction industry, the current common practice is to add insulation materials to the outer surface of the wall that meets certain material requirements, such as pasting polymer or extruded board and other insulation materials on the outer wall. These energy-saving methods have their own advantages and disadvantages. Usually, the cost of insulation materi...

Problems solved by technology

The biggest problem of this patent is that the heat transfer coefficient of the thin wall is very high. In summer, the effect of using the air layer to block heat is not good, but in winter when there is no solar radiation, it just increases the heat transfer of the outdoor cold air to the room. Therefore, the practical application The effect is not ideal
