Solar energy storage ventilated heating system

Abstract

The invention discloses a solar energy storage, ventilation and heating system, which comprises a heat storage wall composed of a heat-insulation layer, a heat storage layer and an aluminum plate painted with black paint, a heat storage ventilation channel or a combination thereof, which are sequentially arranged on the outer side of the external wall of a building; a transparent cover plate arranged on the outer side of the heat storage wall or the heat storage ventilation channel; an air sandwich between the transparent cover plate and the heat storage wall; and an upper vent and a lower vent having valves and arranged on the transparent cover plate and the heat storage wall. The solar energy storage, ventilation and heating system can achieve intermittent ventilation and heating without consuming non-renewable energy by using the special heat absorption and release functions of a phase-change heat storage material and by controlling the valves of the vents. The system has the advantages of energy conservation, environmental protection, simple control and handsome structure, and can be widely used for common residential buildings and public buildings.

Description

technical field [0001] The invention relates to building ventilation and heating technology, in particular to a solar energy storage ventilation and heating system. Background technique [0002] With the rapid development of the economy and the improvement of people's living standards, it brings about a sharp rise in building energy consumption. Therefore, in the construction field where energy consumption accounts for such a large proportion of the total energy consumption of the society, energy-saving technology must be emphasized, and the concept of ecological building energy should be vigorously advocated, and clean and renewable energy should be used as much as possible to achieve the goal of building, energy, environment and the whole sustainable development of human society. As the most abundant and most potential energy resource in the world, the utilization technology of solar energy has always attracted the attention of all countries in the world. [0003] At pre...

Problems solved by technology

[0003] At present, solar energy technology has been greatly developed around the world, but solar energy is unstable. When the solar radiation is strong, there will be residual heat that cannot be effectively used. When the solar radiation is weak, it cannot provide enough energy for buildings. use

However, most of the existing technologies for utilizing solar energy need to consume other forms of energy in order to utilize solar energy. Therefore, these technologies are not conducive to energy conservation.

CN101149166A discloses a solar heat collection and heat storage system combined with the exterior wall of a building. The system can collect solar energy and transmit heat energy to the solar room, and store excess heat in the masonry wall for rainy days or nights. However, the system has poor heat insulation effect in summer, and the heat absorbed by the heat-absorbing layer will be transmitted to the room through the wall, making the room hotter; in winter, the heat storage is not enough to effectively heat the room

In addition, the system can only operate when there is solar energy, the operating conditions are not stable enough, and intermittent ventilation and heating control cannot be realized
