摘要

构建兼顾清洁高效供暖和电网削峰填谷需求的 PV/T-热泵联合谷电蓄热供暖系统（PV/T-HP-VEHSH）,基于模式搜索算法提出以供热量、碳排放量和初投资为目标的系统优化设计方法,用TRNSYS研究其运行特性,对比分析其与光伏联合空气源热泵供暖系统和不考虑谷电蓄热的PV/T-热泵供暖系统的性能提升。结果表明：PV/T-HP-VEHSH综合效益最佳时,单位PV/T面积匹配的集热泵流量和集热水箱容积分别为13.8 （kg/h）/m²和0.1 m³/m²,单位蓄热水箱容积匹配的电锅炉容量为1.2 kW/m³;PV/T-HP-VEHSH供暖季月均性能系数（COP）为2.8~3.2,PV/T综合效率超过56%;谷电蓄热使PV/T-HP-VEHSH运行成本降低3.3元/m²。

Abstract

Considering the demands of clean and efficient heating with grid peak shaving and valley filling, a novel building heating system combined with photovoltaic/thermal, heat pump and heat storage using off-peak electricity （PV/T-HP-VEHSH） was proposed. The optimization design method for PV/T-HP-VEHSH was developed targeting optimal heating reliability, minimal carbon emissions and initial investment based on the pattern search algorithm. The operating performance of PV/T-HP-VEHSH was studied by TRNSYS software and the performance improvement was also investigated in comparison with the photovoltaic-air source heat pump heating system and the heating system without thermal storage by off-peak electricity. The results show that the PV/T-HP-VEHSH has the optimal comprehensive benefits at the ratio of flow rate of the thermal collection water pump to PV/T area of 13.8 （kg/h）/m², the ratio of volume of thermal collecting tank to PV/T area of 0.1 m³/m², and the ratio of electric boiler capacity to volume of thermal storage tank of 1.2 kW/m³. The average monthly COP of PV/T-HP-VEHSH varies from 2.8 to 3.2 and the comprehensive photoelectric and photothermal efficiencies of PV/T are higher than 56% during the heating season in cold zones. The operation cost of PV/T-HP-VEHSH is reduced by 3.3 ¥/m² due to the thermal storage using off-peak electricity.
