摘要/Abstract

摘要： 为实现地源热泵 (Ground source heat pump, GSHP) 系统仿真平台的建立,基于GSHP机组的机理知识和样本数据采用多元非线性回归方法,建立GSHP机组半经验数学模型,开发GSHP机组仿真模块Type223,并通过仿真分析,验证了模块的准确性。利用Type223模块搭建了GSHP系统TRNSYS(Transient System Simulation Program)仿真平台,研究了变频控制下地源热泵系统地源侧变流量的运行特性。结果显示：相对于定流量系统,变流量系统的GSHP机组运行能耗有所增加,但地源侧循环泵的运行能耗大幅度降低,整个制冷期地源侧总能耗的节能率可达7.99 %。

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.

Key words: GSHP, mathematical model, multiple nonlinear regression, variable frequency control, energy simulation
