| 摘 要： | 为了充分利用土壤热能，对热泵供热量、运行时间与系统性能之间的关系进行研究。通过对采暖房间建立逐时热平衡方程，推导出房间温度变化与时间关系的计算式。通过该式计算出不同情况下室内平均温度、热泵运行时间、停机时间、供热运行份额的数值，对5种运行方案进行模拟计算分析。结论如下：地下盘管长度设计计算中供热运行份额应根据热泵机组制热量计算得出。热泵制热量相同时时间周期（一次运行时间与停机时间之和）小，运行时间短，地下盘管出口平均水温高，热泵运行效率高，但是随着时间周期变小，室内平均温度下降，热舒适性降低。时间周期相同时热泵制热量越大，运行时间越短，地下盘管出口平均水温高，热泵运行效率高。根据这些特点可采用100%设计热负荷的热泵机组+20%～30%设计热负荷的辅助热源的形式进行热源的配置。

| Abstract: | In order to make full use of soil heat energy, the relationship between heat supply, running time and system performance was studied. By establishing the hourly heat balance equation of the room, the calculating formula on room temperature change and time was derived. The average indoor temperature, heat pump running time, downtime, and heating running share were calculated by this model, and the simulation calculation and analysis of five operating schemes were carried out. |
