摘    要:以TRNSYS为仿真平台,结合某工程实例,建立一个带热回收的土壤源热泵系统的数字仿真系统。通过研究其夏季冷凝热的计算机模拟及热水供应变化规律,计算出系统热回收装置开启和关闭时不同工况下性能参数。基于此模拟结果,根据热经济学原理,分析比较三种冷凝热回收方式在额定工况下的技术可行性和经济性,最后提出土壤源热泵冷凝热回收最优方式。

Abstract:

A digital simulation system of ground-source heat pump with heat recovery was established combined with a project example based on TRNSYS as the simulation platform system. By computer simulation of condensing heat in summer and study of hot water supply change rule, the performance parameters were calculated when the heat recovery device was open or closed under different conditions. Based on the simulation results, an optimized scheme for proposing three ways of heat recovery was discussed and compared according to the technical economics, and the possibility of adding condensing heat recovery system on design conditions from the point of both technical and economic was analyzed.
