多时间尺度下间接式PV/T热泵供暖系统运行特性研究
Study on the Operational Characteristics of Indirect PV/T Heat Pump Heating Systems Under Multiple Time Scales
摘要
Abstract
In response to the urgent demand for clean heating in rural areas,a heat pump heating system utilizing indirect photo voltaic/thermal(PV/T)components has been proposed.This study focuses on a single household building(64 m2)located in a village in the Lanzhou region.A simulation model was constructed using the TRNSYS dynamic system simulation software platform,analyzing the operational characteristics of the system across three time scales:hourly,daily and during the heating period.The research investigates how variations in heat pump rated thermal power and thermal storage tank volume affect system performance.The results indicate that when the heat pump's rated thermal power is set at 2.50 kW and the thermal storage tank volume is 0.9 m3,the system effectively reduces the average temperature of the thermal storage tank.Consequently,total electricity consumption during peak periods is lowered to 536.2 kW·h.The average electrical efficiency of PV/T components reaches 12.3%,while their average thermal efficiency stands at 35.35%.Additionally,the solar energy guarantee rate for this system is recorded at 77%,with an overall system efficiency of 49%.This optimized parameter combination demonstrates significant advantages for PV/T heat pump heating systems applied in rural clean heating contexts;it effectively enhances energy utilization efficiency and reduces operating costs,providing a viable solution for clean heating technologies in rural areas.关键词
