Stimulation and Optimization of Parabolic Trough Solar Hot Water System

Abstract:

We firstly established stimulation model of parabolic trough solar hot water system with TRNSYS software.Based on the simulation model and the weather data of typical meteorological year in Tianjin,research was made on simulation and optimization from three aspects including the type, the inclination and azimuth,the ratio between the tank volume and the collector area,the water temperature ,the load and the tube length.We found that the efficiency and solar fraction of different types is different in 12 months throughout the year;There are great differences in the performance of different inclination and azimuth;The yearly efficiency and solar fraction will increase with the increase of the ratio between the tank volume and the collector area;When the temperature of water increases, the yearly efficiency and solar fraction will decrease and when the water load increases,the yearly efficiency will increase while the solar fraction will decrease;With increasing of the tube length ,the yearly efficiency and solar fraction will decrease.
