Application
CN201610426075.5 discloses a low-loss, high-efficiency solar heating system, comprising: a solar energy collection system that gathers dispersed solar energy and converts it into heat energy; an energy storage system that forms an energy storage circulation pipeline with the solar energy collection system, wherein the energy storage medium absorbs heat energy; a heating system having a heat storage tank and heat dissipation equipment, wherein the energy storage circulation pipeline passes through the heat storage tank to heat the heating medium inside the heat storage tank; and a medium-low temperature power generation system having a low-boiling-point medium that absorbs heat from the energy storage medium; wherein the heating medium comprises 30-50 wt% lanthanum bromide, 20-40 wt% samarium bromide hexahydrate, 20-40 wt% cerium bromide, 0.3-0.8 wt% polyethylene glycol, and 0.2-0.5 wt% mannitol. This invention has a reasonable design, significant energy-saving effect, high efficiency, and the insulation layer design ensures safe operation of the system in cold winters and freeze protection in the event of unexpected power outages.
