| In the face of rising energy and environmental problems,how to make better use of renewable energy in order to realize the sustainable development is an important problem faced by human.The purpose of this paper is to study the new way of solar energy utilization,to breakthrough the limitations of traditional solar energy utilization and to achieve the solar energy utilization in the increasingly dense city.This paper mainly aimed at simulate the photovoltaic/solar thermal(PV/T)panels system running situation in Shenyang area.Firstly according to the meteorological parameters of Shenyang area on its annual solar radiation conditions and influence factors to build a model,to analyze the solar radiation characteristics of Shenyang area and to build model of the photovoltaic/solar thermal panels.Secondly according to the model of PV/T panels,choose to decorate the panels vertical to the ground in the south facade of building and 42' inclined on the roof.Then using Fluent to simulate PV/T panels and ordinary PV panels under the condition of high temperature,low temperature,and month by month respectively,get the simulation result of temperature field.Thirdly according to the simulation temperature results of PV/T panels and ordinary PV panels,compared with them to get the effect of PV/T panels.Then get the photoelectric conversion efficiency PV/T panels can improve,to evaluate the running situation of PV/T panels.Finally calculating the solar energy utilization ratio PV/T panels,including photovoltaic and thermal conversion efficiency.To convert the conversion solar energy into primary energy,for its energy-saving evaluation.And then build the actual engineering model,use high-rise building for the model,PV/T panels will according to the characteristics layout on the building model.Simulating the operation of the covered and uncovered PV/T panels,in order to get the PV/T panels energy-saving effect in engineering application and evaluate the whole system running. |
