摘 要: 根据海相沉积砂岩——设计了土壤源热泵热水系统。试验采用单因素法,在连续和间歇运行两种工况下研究不同热负荷下系统的运行情况及土壤换热能力(通过控制开启主机的数量和土壤换热井数量来改变热负荷大小);在主机停止工作后,让土壤换热器中的循环介质与大地进行充分换热,测试土壤换热器中循环介质的温度变化来判断埋管区土壤温度场的恢复能力,从而综合评价地源热泵热水系统的运行性能。 According the mutually area of Sea and sandstone' s deposits, this paper introduces the hot-water system of ground source heat pump (GSHP). By using single factor, The author studying the function of this system and the heat exchange ability of the ground source, under the condition of continuous mode and intermittent mode (by controlling the amount of machine and the length of well) ; By testing the circulating medium' s tempera, ture to find the recover ability of ground source' s temperature field, after the machines stopping work and felling heat exchange during the circulating medium and ground source.
