Abstract

The invention discloses a passive type solar heat-collection and energy-saving wall system of low-storied buildings, and relates to an energy saving wall system, which solves the problems that a conventional passive type solar heat collection wall is high in wall heat transfer coefficient, large in heat loss and low in heat supply efficiency and is not beneficial to indoor heat preservation as an upper vent hole and a lower vent hole are formed in the wall when being used for indoor heat supply. The passive type solar heat-collection and energy-saving wall system comprises a glass shade, a heat collection wall, a window and a heat preservation board. The wall system further comprises a ventilation window and a heat exchange ventilation device, wherein the ventilation window is arranged on a glass surface at an upper frame of the window; the heat exchange ventilation device is arranged on the lower vent hole; the ventilation window is used for controlling the air in an air interlayer between the glass shade and the heat collection wall to flow into a room; the heat exchange ventilation device comprises a wooden frame and a heat preservation cover plate; the heat preservation cover plate is hinged with the wooden frame and covers the wooden frame; and the heat preservation cover plate is formed by two plywoods and an extruded sheet between the two plywoods. The wall system is applicable to the low-storied buildings.

Description

technical field [0001] The invention relates to an energy-saving wall system, in particular to a passive solar heat-collecting energy-saving wall system. Background technique [0002] The winter in northern my country is long and cold. Therefore, buildings need to consume a lot of energy for indoor heating. At present, coal and other non-renewable resources are mainly used. In this process, a large amount of greenhouse gases are generated, which seriously affects the ecological environment. Therefore, looking for a Clean renewable energy instead of coal heating is the fundamental way to solve this problem. [0003] Solar energy is an inexhaustible clean energy. Currently, there are two main ways to use solar energy in buildings: one is solar water heating, and the other is solar power generation. The former is easy to use but only provides hot water for residents; the latter has high initial investment and needs to form a certain scale to be beneficial, so it is also limited...
