Study on Heating System of Solar Energy Combined with Bioenergy

In order to employ the solar energy and bioenergy efficiently and economically, a new model of heating system is established for theoretically studying the exergy and energy utilization of solar energy and bioenergy on the basis of the Integrated Cascaded Utilization of Chemical and Physical Energy Principle. The results indicate, the low temperature floor radiation heating way is better than the traditional radiator heating way, and compared with traditional direct burning biomass heating, the energy and exergy utilization efficiency of the new system are more than 89% and 20% respectively, and the capital recovery period is less than 3 years.
