为缓解中国北方冬季供暖能耗普遍偏高的问题
以邯郸某小区为研究对象
结合当地峰谷电价差
通过TRNSYS软件构建基于低谷电驱动的光伏光热耦合中深层地源热泵供暖系统(PV/T-GSHP)模型。对在低谷电驱动下系统的运行策略进行探讨
对以供暖为主的地区使用地源热泵系统(GSHP)长期供暖土壤热失衡问题进行研究
分析系统在有无谷电蓄热的情况下对供暖性能的影响
最后对PV/T-GSHP系统进行能源、环境和经济性评价。研究结果表明:PV/T-GSHP系统最佳运行策略为方案3
整个供暖季谷电利用率达90%以上;系统全年累计向土壤补热量比土壤放热量多976.82 kW·h
可保持土壤热平衡;相较于传统供暖系统
PV/T-GSHP系统最高可节约74.93%的能耗;CO2减排率最大可达74.94%;系统运行费用最高可节约77.27%。
To address the significant energy consumption associated with heating during winters in northern China
a residential community in Handan is examined. A model of a photovoltaic photo-thermal coupled medium-deep ground source heat pump (PV/T-GSHP) system
driven by low valley electricity
is constructed using TRNSYS software. This model takes into account the local disparities between peak and valley electricity prices. The operational strategy that utilizes low valley electricity is investigated
alongside an analysis of the soil thermal imbalance issue encountered by the ground source heat pump (GSHP) during long-term heating. The effects on heating performance are analyzed both with and without valley electricity heat storage
culminating in an evaluation of the PV/T-GSHP system concerning energy efficiency
environmental benefits
and economic viability. The findings indicate that: the optimal strategy for the PV/T-GSHP system is Scheme Ⅲ
achieving over 90% utilization of valley electricity during the heating season; the annual cumulative heat replenished to the soil is 976.82 kW·h more than the heat extracted from the soil
maintaining the soil thermal balance; energy consumption is reduced by up to 74.93% compared to conventional systems; CO emissions can decrease by as much as 74.94%
and operational costs may drop by up to 77.27%.
