摘要
以青海省西宁市一独立建筑为例,介绍了以空气源热泵为核心搭建的太阳能-空气源热泵联合供热系统(以下简称“联合供热系统”)的仿真模型和实际供暖效果,并将其与单纯的空气源热泵热水机组进行经济性和CO2排放量的比较。实验结果表明:在测试时间段内,空气源热泵加热系统的ηCOP,h的平均值为2.36,达到了节能要求;室内平均温度维持在21.94℃左右,完成了供暖目标;联合供热系统在经济性和降低CO2排放方面的表现更加优异。
Taking an independent building in Xining City,Qinghai Province as an example,this paper introduced the simulation model and actual heating effect of a solar-air source heat pump combined heating system(afterwards referred to as"combined heating system")built with air source heat pump as the core,and compared it with pure air source heat pump hot water unit for economy and carbon dioxide emissions.The experimental results show that during the test period,the average of ηCOP,h of air source heat pump heating system is 2.36,which meets the energy-saving requirements;the average indoor temperature is maintained at about 21.94℃,which means the heating target is completed;the combined heating system performs better in terms of economy and reduction of carbon dioxide emissions.
