Contrastive Analysis of Solar-Ground Source Heat Pump Coupling System Based on TRNSYS

本文针对邯郸市某高校实验室搭建太阳能-地源热泵并联系统、太阳能-地源热泵串联系统、地源热泵系统进行模拟仿真研究。以TRNSYS软件搭建仿真模拟平台,模拟邯郸室外环境变化情况及分析邯郸地区室外环境对这三种系统运行的影响。搭建实验室建筑围护结构模拟系统,进行负荷计算。模拟这三种系统在冬夏季运行时的土壤温度、源侧供回水温度、热泵机组消耗功率以及COP进行对比分析,得出三种系统运行时,冬季串联系统供暖与夏季并联系统制冷效果较好,全年运行串联系统消耗功率较低,节能效益好,为搭建地源热泵系统提供指导意义。

In this paper, the parallel system of solar energy and ground source heat pump, the series system of solar energy and ground source heat pump and the ground source heat pump system were built in a university laboratory in Handan City to carry out the simulation research.TRNSYS software was used to build a simulation platform to simulate the changes of outdoor environment in Handan and analyze the influence of outdoor environment on the operation of the three systems.Build laboratory building envelope simulation system,load calculation.Simulation of the three systems in the runtime of the soil temperature during summer and winter seasons,the source side consumed power and COP for the return water temperature,heat pump unit,this paper compares and analyzes three kinds of system running,winter heating and summer series system paralleling system refrigeration effect is good,running all the year round in series system with low power consumption,good energysaving benefit,provide guiding significance for building ground source heat pump system.
