Application example of flat solar water heater heating system Http:// Ll , a solar heating system in Hangjiatun Village, Pinggu District, Beijing, designed by Beijing Solar Energy Research Institute , uses solar floor radiant heating technology combined with biomass boiler as auxiliary energy to realize renewable energy to solve rural heating, hot water and cooking. Demand. Each residential building in the new rural construction is a two-story small building, designed according to Beijing's 50 % building energy efficiency standards. Figure 10 . 12 is the appearance of the solar heating system residential. According to the thermal load and roof condition of the house, the system installs a 28m square flat solar collector , uses forced circulation, uses water as the heat transfer medium, and adopts the temperature difference control circulation method to implement the anti-freezing and anti-overheat design scheme. The solar heating system adopts a composite water tank, and the open type hot water storage tank and the closed domestic hot water tank are nested together, and the domestic hot water tank is used to heat the domestic hot water. The open type hot water storage tank is suitable for the falling water type solar water heating system, and has the advantages of simple structure and low cost; the closed domestic hot water tank uses the water tank wall to heat the domestic hot water, saves the heat exchange equipment, and utilizes the water pipe network. Pressure provides bathing water, no need to install water supply pump, reduce investment and use cost; domestic hot water tank is separated from solar collector system and heating system, and enamel water tank is used to ensure that domestic hot water meets drinking water quality standard; domestic hot water A volumetric electric heater is used . Improve the instantaneous hot water supply capacity; nested water tanks can also greatly increase the hot water demand during the non-heating season hot water supply " farmhouse " travel.
