The Solar Collector Calculation in Integrative Solar Architecture

摘要

Energy is an important material foundation of the economical and social development. Building energy consumption has become an important part of the total social energy consumption. Develop and use renewable energy is importance for building energy efficiency and many countries made clear renewable energy development goals in the world. China is actively promoting Integrative Solar Architecture, solar heating and solar hot water systems are important part. In China, solar radiation is large in summer and only solar water heating needed, solar collector area need small. In winter, both solar hot water and solar heating needed, but the solar radiation is smaller, so the solar collector areas have multiplied. The relevant norms and the manual give the methods for calculation solar collector areas for solar heating and solar water heating used alone. But they did not give the method of how to calculation the solar collector areas when the solar hot water and solar heating used at the same time. This paper combination of meteorological parameters, simulates the typical architectural which use solar heating and solar hot water at the same time, and gives the method of calculation solar collector area.
