Numerical Simulation of High Mass Flow Rate Operation of Flat Plate Solar Collector in Winter
摘要
Abstract
An operation scheme with a high mass flow rate was proposed to address the problem of in-sufficient hot water temperature in the winter of the flat plate solar collector(FPSC)to improve the heating performance as well as the annual utilization rate of the system.Using CFD technology to sim-ulate the temperature changes of each component of the FPSC system under different flow conditions(0.02～0.15 kg/s),calculate the thermal efficiency of the system,and compare the advantages of high mass flow rate operation through the temperature nephogram.The result shows that the high mass flow rate operation can reduce the heat loss than that of the low mass flow rate and achieve better thermal performance.关键词
