摘　　要：为了实现太阳能供暖系统的高效运行,本文采用TRNSYS软件对太阳能空气源热泵供暖系统进行了模拟仿真。研究不同蓄热水箱体积与集热面积配比(VAR)下复合供暖系统的集热效率,有效集热量及空气源热泵供热量的变化情况,设计7组VAR参数,分别为0.235m,0.115m,0.073m,0.053m,0.041m,0.033m和0.027m。结果表明:随着VAR的减小集热器的平均集热效率和有效集热量有所减小,且随着VAR的减小集热效率降低的幅度也有所增大。随着VAR的减小,空气源热泵供热量有所增加,且空气源热泵的供热量在11月份和3月份较少,1月份最大。In order to realize the efficient operation of solar heating system,TRNSYS software was used to simulate the solar air source heat pump composite heating system.The variation of heat collection efficiency,effective heat collection and heat supply amount of air source heat pump in the composite heating system under different heat storage tank volume and heat collection area ratio(VAR)was studied.Seven groups of VAR parameters were designed,which were 0.235 m,0.115 m,0.073 m,0.053 m,0.041 m,0.033 m and 0.027 m respectively.The results show that the average heat collection efficiency and effective heat collection efficiency of the collector decrease with the decrease of VAR,and the decrease amplitude of the heat collection efficiency also increases.With the decrease of VAR,the heating quantity of air source heat pump increased,and the heating quantity of air source heat pump was less in November and March,and the heating quantity of air source heat pump was the largest in January.
