Research On Application Of Biomass And Air Source Heat Pump Combined Heating System In New Rural Community In Northern China

At present,the state is vigorously promoting clean energy heating,to replace the serious pollution of fossil fuel heating.Air energy and biomass energy are good clean energy,the tWo are reneWable energy.Taking into account the rapid development of neW rural communities in recent years,this paper presents a multi-element heating system for air source heat pump and biomass energy,and the north of 50,000 square meters of rural neW community for the calculation of cases,In this paper,the system is optimized,analyzed and analyzed for environmental benefits,and it has a certain guiding significance to replace the traditional fossil fuel heating.This topic is derived from <Large Scale Renewable Energy Development Project of China> undertaken by Qingdao Technological University,and supported by the Chinese government / World Bank / Global Environment Facility department.This paper analyzes the heating status of the three heating methods of biomass(direct combustion of biomass fuel,biogas cogeneration and MSW incineration)and the existing policy to obtain the theoretical heating applicability.It is found that the biomass boiler and air source heat pump combined heating system has advantages in terms of resource conditions,heating stability and environmental protection.This is the foundation for the later simulation and analysis of biomass boiler and air source heat pump combined heating system.In the TRNSYS platform,the topic establishs a biomass boiler+air source heat pump combined heating system model for instantaneous simulation.First of all,under the existing cost level,the optimal cost is obtained by optimizing the factors such as the different ratio of the system,the different price policy and the different Water tank,and the optimal ratio of the scheme under the different price policy and the optimal Water tank.Secondly,the main influencing factors include different regions(North China,NorthWest and Northeast),different price,different biomass fuel prices and different loan interest rates.Finally,compared With other traditional heating methods(gas boilers,electric boilers,biomass boilers,etc.),it is concluded that the biomass boiler+air source heat pump combined heating system is more economical and has better energy saving than coal-fired boilers RoW efficiency.Through the research and analysis of this subject,it has a certain significance for the future promotion of biomass boiler+air source heat pump combined heating system in the northern region.
