Abstract

Abstract: For the purpose of building a simulation platform of GSHP system, a semi empirical mathematical model of GSHP unit adopting multiple nonlinear regression method was established based on the mechanism knowledge and the sample data of GSHP unit. A GSHP unit module was developed, namely Type223, and its accuracy was verified by simulation analysis. A TRNSYS simulation platform of GSHP system was built by Type223 module. The operation characteristics of variable flow on ground source side of GSHP system was studied under variable frequency control. The results showed that, the energy consumption of GSHP unit is increased compared with the constant flow rate system, but the energy consumption of circle pump is greatly reduced. The energy saving rate is 6.47% during the whole cooling period.
