Solar heat accumulation type passive solar house

Abstract

The invention discloses a solar heat accumulation type passive solar house. A solar water heater communicates with a roof warming assembly. A passive ventilation heat exchange wall is arranged on the inner side of a glass seal plate. An upper ventilation assembly is arranged on the upper portion of the passive ventilation heat exchange wall. A lower ventilation assembly is arranged on the upper portion of the passive ventilation heat exchange wall. By means of the upper ventilation assembly, gas flow is made to flow to the indoor portion from a cavity; and by means of the lower ventilation assembly, the gas flow is made to flow to the cavity from the indoor portion. By arranging the passive ventilation heat exchange wall, by means of an outer honeycomb structure heat conduction layer, an inner honeycomb structure heat conduction layer and a honeycomb porous structure, the absorption rate and storage amount of solar energy are increased, and heat in a phase change heat storage box can be slowly released to the indoor portion; the loss of energy consumed by the underground portion is reduced through a water isolation layer according to the property that the specific heat capacity of water is large; and by means of the upper ventilation assembly and the lower ventilation assembly, the flow direction of the gas flow can be ensured, circulation of the indoor gas flow is achieved, and the effect that hot gas inflows from the upper portion and cold gas outflows from the lower portion is ensured.

Description

technical field [0001] The invention relates to a solar thermal storage type passive solar house, which belongs to the technical field of solar energy utilization. Background technique [0002] In recent years, my country's construction industry has been booming, and the electricity consumption and energy consumption of buildings have also increased rapidly. Building energy consumption accounts for about 20% to 30% of the country's total energy consumption, and will account for 30% to 40% in the near future, reaching the level of developed countries in the world. And in my country's total energy consumption, clean energy only accounts for a small part. Compared with fossil fuels such as coal, petroleum, and uranium, solar energy has four advantages: universal, clean, long-lasting, and large in volume. There are various forms of utilization of solar energy, among which the passive solar of the Trumpet heat collecting wall is an effective form. Therefore, the development of ...

Problems solved by technology

[0004] However, the current passive solar house has low solar energy utilization rate, low heat storage capacity and efficiency, and still needs to install heating equipment such as coal power in winter, which affects building energy consumption. Therefore, it is necessary to design a novel solar energy storage system. Thermal passive solar house, improving heat storage effect and energy utilization rate
