基于风光互补的农村住宅联合供热系统研究

Research on Combined Heating System for Rural Residential Houses Based on Wind-Solar Complementation

针对张家口坝上地区农村住宅冬季供热问题,构建由太阳能集热器供热结合风力、光伏发电供热组成农村住宅的联合供热系统。通过网络化智能化控制,充分利用太阳能和风能供热,控制风力光伏发电系统、太阳能集热器、电锅炉、蓄电池组、蓄热水箱和换热给水系统协调工作,来适应风能和太阳能辐射强度动态变化,解决风能、太阳能辐射强度变化热源不稳定及建筑供暖需求连续稳定之间的矛盾,满足北方坝上地区农村居民冬季连续供暖和日常生活热水需要。

Aiming at the heating problem of rural houses in the Bashang area of Zhangjiakou in winter,a combined heating system for rural houses is constructed by combining solar collector heating with wind power and photovoltaic power generation heating.Through networked intelligent control,make full use of solar energy and wind energy for heating,control the coordinated work of wind photovoltaic power generation system,solar collector,electric boiler,battery bank,hot water storage tank and heat exchange water supply system to adapt to dynamic changes of wind energy and solar radiation Intensity.It solves the contradiction between the unstable heat source of wind energy and solar radiation intensity and the continuous and stable heating demand of buildings.It meets the needs of rural residents in the northern Bashang area for continuous heating and hot water for daily life in winter.
