摘要
为解决农村地区冬季供暖问题,推动农村能源低碳转型,本文提出一种适用于新农村住宅的空气源热泵辅助太阳能、沼气互补供暖系统,并对系统关键参数进行优化研究。首先,建立了太阳能-沼气-空气源热泵互补供暖系统仿真模型,进行了多能互补供暖系统的运行控制策略分析;其次,以费用年值最小为目标函数,对太阳能集热器的面积、倾角、方位角、蓄热水箱容积和沼气池容积进行了参数优化;最后,对优化前后的供暖系统的性能进行了比较和讨论。结果表明,优化前后室内温度和沼气池温度分别保持在20℃和26℃,优化后系统耗电量相较优化前节省28.5%的电能,空气源热泵COP由3.12提高到3.88。本研究结合太阳能、沼气和空气源热泵技术的优势,可以为农村地区供暖系统的设计和实施提供有价值的见解。
To address the heating needs in rural areas and promote the low-carbon transformation of rural energy,this study proposes an air source heat pump-assisted solar and biogas complementary heating system suitable for rural residential buildings.Firstly,a simulation model of solar-biogas-air source heat pump complementary heating system was established,and the operation and control strategy analysis of the multi-energy complementary heating system was carried out.Secondly taking the annual cost of the system as the objective function,The optimization parameters include the area,tilt angle,azimuth angle of the solar collector,as well as the volume of the thermal storage tank and biogas digester.Finally,a comparison and discussion of the performance of the heating system before and after optimization are presented.The results show that after optimization,the indoor temperature and biogas digester temperature are maintained at 20℃and 26℃,respectively.The optimized system achieves a 28.5%reduction in electricity consumption compared to the pre-optimized system,and the COP of the air-source heat pump increases from 3.12 to 3.88.This research provides valuable insights for the design and implementation of heating systems in rural areas,combining the strengths of solar energy,biogas,and air source heat pump technologies.
