Optimum Analysis on the Thermal Performance of the Small-sized Biogas Fermentation Tank Based on Annual Energy Consumption Simulation

In order to reduce energy consumption, investment and operating costs of the small-sized biogas fermentation tank to promote the energy efficiency of rural building, its thermal performance has been researched for optimization in this paper. Firstly, we established the annual comprehensive energy consumption method of biogas fermentation tank based on annual meteorological data of 8760 hours, which is more rigorous and accurate than the conventional method. And then, the optimization research is carried out at the three aspects of solar radiation, surface area and insulation, correspondingly, the optimum method and result is promoted for providing guidance for engineering design.
