摘　　要：为了解决地热热泵系统输出能量和用户需求能量之间的平衡问题,就必须选择出适宜的能量调节方式并加以研究。首先,对现有的几种能量调节方式进行了比较,发现了适宜的调控方式;然后,在小型地热热泵系统上进行了变频试验研究,频率变化范围为30～55Hz;最后,得出了系统各主要参数随频率的变化规律。此结论可以在制定地热热泵系统能量输出的调节策略中起到一定的指导作用。In order to match the export capacity of geothermal heat pump system (GHPS) and the actual load, selection of suitable adjustment mode for GHPS and the influence of such mode on cycling parameters of GHPS are researched. Firstly, some adjustment modes are compared and it is found that the mode of import frequency conversion of compressor is better than others in GHPS. Secondly, experiments on a GHPS are done, with the frequencies changing from 30 Hz to 55 Hz. Lastly, based on the analysis of experimental data, the relationships between the compressor frequency and other important parameters are given, which may be helpful to adjust GHPS' export capacity.
