摘要

为研究严寒地区太阳能-地源热泵系统不同方案下的运行效果,基于Fluent建立耦合系统数值仿真模型,对传统地源热泵运行方案、太阳能-地源热泵均匀蓄热与分区蓄热方案进行完整运行周期仿真和对比分析。结果表明：跨季节蓄热系可实现热量跨季节储存和利用,同时可有效提升地源热泵系统能效,降低系统全年能耗20%以上;采用分区蓄热方案后蓄热体热量集中在内区,同时可降低蓄热体外区温度,全年热量损失由38.71%降至19.19%,可有效提升跨季节蓄热效果和热泵能效、降低系统全年能耗。

Abstract

To investigate the performance of different operating strategies of a solar-assisted ground source heat pump （SGSHP） system in severe cold regions, a numerical simulation model is developed based on Fluent. Three operating modes are simulated and compared： a conventional ground source heat pump（GSHP） system, an SGSHP system with uniform heat storage, and an SGSHP system with partitioned heat storage. The results show that the coupled system achieves cross-seasonal heat storage and utilization. It also improves the energy efficiency of the ground source heat pump system and reduces the annual energy consumption by over 20%. The partitioned operating strategy demonstrates superior thermal regulation, concentrating heat storage in the inner zone and simultaneously lowering the outer zone temperature. The annual heat loss is reduced significantly from 38.71% to 19.19%, which improves the cross-seasonal heat storage efficiency and heat pump performance. The annual energy consumption of the system is further reduced.
