摘要

光伏/热(PV/T)热电联产的性能与环境温度密切相关。为了获得适用于寒冷地区的微型热管光伏/热(MHP-PV/T)系统的PV/T性能，在45°安装角下，比较相同截面面积的梯形MHP-PV/T(梯形通道截面MHP-PV/T, T-MHP-PV/T)和矩形MHP-PV/T(矩形通道截面MHP-PV/T, R-MHP-PV/T)系统的性能，得出截面形状对MHP-PV/T系统热电产性能的影响。结果表明:当室外初始环境温度为19℃时，MHP-PV/T可以正常启动;R-MHP-PV/T系统的电效率与T- mhp - pv /T系统相似，但热效率、总能量功率和总能量效率明显优于T- mhp - pv /T系统。研究结果对MHP-PV/T在寒冷地区的应用和推广具有指导价值和意义。

Study on Performance of MHP-PV/T with Different Cross Sections in Cold Regions

The cogeneration performance of Photovoltaic/Thermal (PV/T) is closely related to the ambient temperature. In order to obtain the PV/T performance suitable for cold areas based on the micro heat pipe Photovoltaic /Thermal (MHP-PV/T) developed in the early stages, the performance of trapezoidal MHP-PV/T (Trapezoidal channel section MHP-PV/T, T-MHP-PV/T) and rectangular MHP-PV/T (Rectangular channel section MHP-PV/T, R-MHP-PV/T) with the same cross-section area are compared at 45°installation angle to obtain the effects of cross-section shape on the cogeneration performance of the MHP-PV/T system. The results show that the MHP-PV/T can start normally when the initial outdoor ambient temperature is 19°C; the electrical efficiency of the R-MHP-PV/T system is similar to that of the T-MHP-PV/T system, but the thermal efficiency, total energy power, and total energy efficiency of the R-MHP-PV/T system are significantly better than that of the T-MHP-PV/T system. The results of the study provide guidance value and significance for the application and promotion of MHP-PV/T in cold regions.
