Winter heating in rural areas in shandong district are mainly composed of traditional way of coal,fossil fuels such as coal,oil,natural gas decline,environmental pollution aggravate,biogas and solar energy as a clean and renewable energy,with winter heating areas,in rural areas can not only make full use of the shandong region rural biogas biomass energy,solar energy and resources,and can solve the problem of single energy heating the effect not beautiful,but also can reduce emissions of pollutants,protect the environment.In this paper,first of all,through field investigation,questionnaire survey and field test methods such as in shandong region rural current heating situation do the investigation and study,for the rural building energy consumption is higher,the winter heating means using stove,heatable adobe sleeping platform,Tu Nuan Qi,heater traditional way more,such as solar power and biogas in the rural areas as a source of living hot water use is more,other renewable energy utilization rate is low,in the shandong region rural development biogas and solar heating has plenty of resources,and rural residents have the urge to improve the current way of heating in winter;According to current situation of the heating area village in shandong,then build a biogas and solar energy heating system,through the study of the design and calculation of system components,building thermal load,pool heat load,solar,etc are all meet the demand of heating in winter of rural residents,in the shandong area of rural biogas and solar energy heating system is a way of sustainable heating energy saving and emission reduction.And then through the establishment of the shandong region rural biogas and solar energy heating system and running,you can solve the problem of low winter methane gas production in shandong district,combined heating system of heating water into the pool,pool for heating,promote the methane gas.Compared with traditional coal-fired heating system,biogas and solar energy heating system be more save energy than traditional coal-fired heating system,energy-saving rate can reach 75.92%,the heating season can save about 1860.86 kg of standard coal,save money about 2791.29 yuan,at the same time,the indoor thermal comfort is much higher than traditional coal-fired heating system,especially to solve the problem of heating in winter night,don't need to manually add coal-fired heating.Finally,through the TRNSYS system model of the simulation results with the experimental results of comparison,get the appropriate TRNSYS system model,using the TRNSYS system model for the heating season,the daily average temperature of outdoor air and indoor air temperature of the heating season daily simulated calculation and sorting into line chart,get along with the change of the average outdoor air temperature,the heating period the whole biogas and solar energy heating system will also be made corresponding change,such not only can save biogas,biomass energy,renewable energy and reduce carbon emissions,protect the environment.Using TRNSYS system calculate the whole heating heating season total heat load and wall of the building heat provided by the gas water heater burning gas,further calculated solar assurance throughout the heating season in shandong area,get the whole heating season in shandong district solar assurance not less than 0.57,more than design value,illustrate the shandong region has abundant solar energy resources in the heating season,and then get biogas and solar heating is feasible.
