Light and thin heat preservation outer wall suitable for near-zero-energy-consumption building in severe cold area
The invention discloses a light and thin heat preservation outer wall suitable for near-zero-energy-consumption buildings in severe cold areas, and belongs to the field of energy conservation of near-zero-energy-consumption buildings. The outer wall comprises an outer acanthus, an airflow hole channel, a heat preservation layer and an inner acanthus, and the outer wall is connected with an original fresh air heat recovery device of the near-zero-energy-consumption building. The airflow hole channel comprises a hole channel inlet, a cavity and a hole channel outlet, and the cavity is located between the outer acanthus and the heat preservation layer; the hole channel inlet is formed below the outer acanthus; the hole channel outlet is arranged above the inner vane plate; an air inlet pipe of an original fresh air heat recovery device of the near-zero-energy-consumption building is connected with an outlet of the hole channel, and an exhaust pipe of the fresh air heat recovery device penetrates through the wall and directly leads to the outdoor environment. The heat transfer coefficient of the outer wall is reduced through the idea of recovering heat through fresh air, and the preheating technology, the heat exchange technology and the heat recovery technology are integrated, so that the outer wall is small in thickness and light, the heat transfer coefficient can be dynamically regulated and controlled, the fresh air consumption and fresh air preheating requirements of a building are met at the same time, and the waste gas heat recovery efficiency of the building is improved.
一种适用于严寒地区近零能耗建筑的轻薄保温外墙，属于近零能耗建筑节能领域。所述外墙包括外叶板、气流孔道、保温层、内叶板，且该外墙与近零能耗建筑原有的新风热回收装置连接；所述气流孔道包括孔道进口、空腔和孔道出口，所述空腔位于外叶板和保温层之间；所述孔道进口在外叶板下方；孔道出口在内叶板上方；近零能耗建筑原有的新风热回收装置的进气管与孔道出口相连，新风热回收装置的排气管穿过墙体直接通向室外环境。本发明通过新风回收热量的思路来降低外墙传热系数，且将预热技术、换热技术和热回收技术集成，使该外墙兼具厚度小、轻质，传热系数可动态调控，且同时满足建筑新风用量和新风预热需求、提高建筑废气热回收效率。
