The Design of The Solar Water Heating System of Civil Buildings
Abstract： This topic is the design of solar water heating system and low temperature hot water floor radiation heating system with heating solar energy. Solar hot water system mainly consists of a solar collector system and hot water supply systems, including solar collectors, water storage tanks, circular pipes, brackets, control systems, heat exchangers and pumps and other equipment and accessories. The main subject of the classification, characteristics and applicability of solar water heating systems, analysis of the Villa hot water system load, hydraulic calculation and equipment selection and the energy efficiency of the system as a whole according to the calculated results. Solar low-temperature radiant floor heating system is mainly composed of solar collector system, auxiliary heating systems, heat storage tank, solar circulating pump, circulation pump to warm the floor coil heating system. The main subject of the structure and working principle of radiant floor heating system, the villa needs to be installed to warm the room heat load calculation, solar collector area, floor heating system designed according to the calculated results.
Keywords：the solar energy; hydraulic calculation; floor heating; heat load calculation
