摘　　要：由于单独采用太阳能不能满足供暖需求,设计出一种具有自动控制功能的太阳能墙-空气源热泵联合供暖系统,用于北方寒冷地区的冬季采暖.通过建立实验室,研究联合供暖系统的供暖效果和能耗水平.实验结果显示:不同天气条件下,联合供暖系统在保障室内温度大于19℃的同时,具有很好的保温作用.采用联合供暖的耗电量相比于空气源热泵单独供暖降低很多,进行全天24 h供暖时,平均可减少19%;进行白天12 h供暖时,平均可减少27%,节能效果显著.建立TRNSYS模型,研究系统的运行COP、太阳能保证率等.模拟结果显示:室内平均温度达到18.7℃;太阳能墙的平均集热效率为0.45;空气源热泵的COP为2.7;联合供暖系统总的COPz为4.3,太阳能保证率为33.4%.Since solar energy alone cannot meet the heating demand,the paper designed a solar wall-air source heat pump combined heating system for heating in winter.A laboratory was built to study the heating effect and energy consumption level of the combined heating system.The experimental results show that under different weather conditions,the combined heating system has a good insulation effect while ensuring an indoor temperature greater than 19℃.The power consumption of the system is much lower than that of the air source heat pump.In the 24-hour heating experiment,the power consumption can be reduced by an average of 19%;in the twelve-hour heating experiment,the power consumption can be reduced by an average of 27%,a significant energy saving effects.A TRNSYS model was established to study the system's operating COP and solar energy guarantee rate.The simulation results show that the average indoor temperature reaches 18.7℃;the average heat collection efficiency of the solar wall is 0.45;the COP of the air source heat pump is 2.7;the total COPz of the combined heating system is 4.3,and the solar energy guarantee rate is 33.4%.
