Wall-mounted solar water heater Changzhou eighth stage of the project since 1992, a large number of fossil energy consumption caused by the global environmental pollution and ecological break, then to human survival and development constitute a serious threat to the development of solar energy back again climax. Solar water heater project definition Changzhou solar collectors are mounted on the wall: the absorption of solar radiation and the resulting transfer of heat energy to heat the working fluid in the system; solar collector itself, although not directly to consumers of the end product, but solar collector is a key component composed of a variety of solar thermal systems. Solar collectors can be classified in several ways, according to heat the working fluid TYPE: liquid collectors (with the working fluid as a heat transfer liquid solar collectors), air collector (using air as the heat transfer working fluid solar collector)
