摘要
通过实验分析得出混合式地源热泵在工程应用中的意义。指出合理的混合式地源热泵冷却塔与地埋管的连接方式,在综合考虑地源热泵地埋管全年吸热排热平衡与地源热泵系统效率的基础上得出混合式地源热泵的合理控制方式和控制参数。指出地埋管单位井深换热量无明确的意义,提出地埋管单位井、地埋管内换热介质与土壤原始温度单位温差换热量的意义,并在本实验中给出地源热泵机组制冷效率与地埋管出口水温的关系。
Analyzes through the experiment obtains the HGSHPs in project application significance. Points out the reasonable cooling tower and the ground heat exchanger connection mode in HGSHPs, Obtains the reasonable control mode and the controlled variable of the HGSHPs on the annual ＂the thermal equilibrium＂, and on the source heat pump system efficiency＇s foundation. Pointed out that the ground heat exchanger unit depth heat transfer quantity is not explicit significance, proposed that the ground heat exchanger unit well, the heat transfer medium and the soil initial temperature unit temperature difference heat transfer quantity＇s significance, and gives the ground source heat pump unit refrigeration efficiency and the ground heat exchanger export water temperature relations in this experiment.
