Solar Engineering of Thermal Processes, Photovoltaics and Wind || Building Heating
摘要： The active systems described in the previous chapter are based on collectors and storage systems that are not necessarily integrated into a building structure. Passive systems can be distinguished from active systems on either of two bases. The first distinction lies in the degree to which the functions of collection and storage are integrated into the structure of the building; windows and the rooms behind them can serve as collectors, with storage provided as sensible heat of the building structure and contents as they change temperature. Second, many passive systems require no mechanical energy for moving fluids for their operation; fluids and energy move by virtue of the temperature gradients established by adsorption of radiation (and hence the term passive). (Mechanical energy may be used to move insulation for loss control or to move fluids to distribute absorbed energy from one part of a building to another.)

Solar Engineering of Thermal Processes, Photovoltaics and Wind || Solar Water Heating
摘要： This is the first of a set of chapters on thermal energy applications. In this chapter, we treat the use of solar heating for domestic or institutional hot-water supplies. Descriptions of systems, components, and important design considerations are outlined. Considerations important in designing water heating systems are also basic to solar heating and cooling systems, applications that are covered in succeeding chapters. Many of the principles noted here for service hot water for buildings also apply to industrial process heat, discussed in Chapter 16.

Reference Module in Earth Systems and Environmental Sciences || Solar Energy in Buildings☆
摘要： Solar Energy can be utilized in many ways (e.g., photovoltaics, solar–thermal–electrical systems, solar ponds, and biomass conversion), but in the current chapter only applications associated with covering the heating and cooling requirements of buildings will be discussed. These applications require low or medium -temperature heat and include water heating, either for domestic hot water systems or swimming pools, space heating, and possibly also space cooling.
