| With the rapid development of industry, improvement of the level of life of people, increase of the energy consumption of buildings and increasing use of fossil fuel, the people all around the world pay much attention to the issues of energy and environment in recent years. To search the way of sustainable development of buildings, energy and environment is staring us in the face. Solar energy is clean, sanitary, unexhausted, and friendly to environment. Integration of solar energy application and buildings is one of the effective approaches to resolve above mentioned problems. Solar energy integrating with buildings is the tendency of synchronous development of energy, buildings and environment. Solar building involves many fileds, and is the result of development and improvement of cross-disciplines. There are many demonstration projects of solar buildings in the world. Because of no systemic estimation theory about solar building, the performances of the buildings exists many disagreements. As we know, the heating duct of the solar energy low-temperature heat-water floor radiant heating system can snugly lay in the building structure. Floor radiant heating system can perfectly integrate into building, and now it is considered as an ideal heating mode. As above mentioned advantages, this heating mode also belongs to the research field of solar building integration. To begin with, the problems of energy consumption of buildings, energy, environment protection, and mainly investigative contents have been roughly discussed in the Chapter 1. Integration modes of solar collector unit and building have been introduced and analyzed in the Chapter 2. Perfect integration mode was obtained in aesthetics. Then, many calculation models, i.e. energy transfer and conversion model of solar collector unit integrated into buildings, indoor temperature model, have been built in Chapter 3. Optimal tilted angles of cylindrical absorber evacuated tube solar collector used for different months and for entire year in Kunming have been calculated, and its optimal tilted angle for entire year is 23.5°. For a flat-plate tube-fin collector and cylindrical absorber evacuated tube solar collector used in Kunming, and the evacuated tube solar collector used in Beijing, the area compensation Ap/Ap0 of collectors at different azimuth and tilted angles have been carried out on conditions that the useful energy output of the collector unit at different angles equals to that of the one facing due south with the optimal tilt angle. The results show that the tilted angle should be controlled in the range of 25°45°; ±30° and ±60° for azimuth angles of flat-plate solar collector and evacuated tube collector. Considering the economic situations, the Ap/Ap0 s; 2.0 for flat-plate tube-fin solar collector... |
