Description

A Modular Dynamic Building Skin Harnessing Natural Energy

technical field

The invention belongs to the technical field of new energy utilization, and relates to a modular dynamic building skin utilizing natural energy.

Background technique

Due to the contradictory nature of winter and summer climates in hot summer and cold winter regions, if we simply adopt the building skin design strategy in cold regions or hot regions, we will fall into the situation of "caring for one and losing the other, and it is difficult to have both". Therefore, it is very necessary to design the building skin that comprehensively utilizes material properties and structural characteristics. The characteristics of heat absorption and emission on both sides of the solar louvers and the structural characteristics of heat storage and heat conduction in the building cavity are used. It can maximize the regulation function of the building skin itself while consuming less energy. In winter and summer, the heat of the sun and the cold of the wind at night are exchanged reasonably with the skin to maintain indoor thermal comfort. Realize the development and utilization of renewable energy with low cost, low environmental load and high comfort.

In regions with hot summer and cold winter, there are many problems in the use of the traditional ventilated building skin—take the double-layer ventilated glass curtain wall as an example. For example, the ventilation and cooling effect is poor in summer, because the double skin, that is, the cavity, only exists on the facade of the building, and the indoor waste heat cannot be discharged in time only through convection. Moreover, the thermal performance of the double-layer glass curtain wall is poor, and it is easy to transmit heat energy from the sun to the room in summer.

In winter, since the heat is mainly stored in the cavity of the facade, the internal walls and floors have no cavity structure, and the heat cannot reach most of the indoor places. The heat is mainly transferred by convection and heat conduction facing the room, resulting in uneven heat distribution in the room, making it difficult to meet the thermal comfort requirements of the human body.

Therefore, how to comprehensively consider the design through the combination of material selection and structural form is of great significance to the improvement of suitable building skins in hot summer and cold winter regions. That is how to discharge the indoor heat in time in summer. How to transport heat to various places indoors in winter. In order to achieve a better indoor thermal comfort environment. It is the main problem of using natural energy to realize the dynamic building skin in hot summer and cold winter regions.
