雨水收集净化加热屋面系统研究

Rainwater Collection and Purification Heating Roofing System

介绍了一种新型的在钢筋混凝土屋面上利用玻璃和陶瓷材料收集、净化以及加热雨水的新型屋面构造。它由玻璃板面层、黑色陶瓷吸光层、普通陶瓷冷却层构成。其中,玻璃板用来收集雨水,并构成温室;黑色陶瓷板则用来接受太阳能辐射,并将其背面的雨水加热;底层陶瓷用来冷凝和收集水蒸气。南四湖区的应用实验数据分析表明,该构造具有较高的吸收阳光、雨水收集和净化能力,应用前景广阔。

Roof areas become larger and larger with the development of cities. The utility of roofs is one fo- cus issue in architecture field. Using the roof to collect and heat rainwater is a reasonable approach. In this paper, a new member that uses glasses and ceramics collect rainwater is introduced. The member is composed by four layers. The glasses are used to collect rainwater and form greenhouse. The ceramic plates with black surface are used to collection sunlight and heat the rainwater. Water vapor is condensate and collected by the bottom ceramic plate. This member with high capacity of collecting rainwater and sun- light absorption is a hopeful roof member.
