Abstract: 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.
Key words: Geothermal heat pump Capacity adjustment Frequency
