Study on Performance of Solar Water Heating System using TRNSYS Software

Abstract

Based on the basic principles of thermodynamics and heat and mass transfer, this paper establishes the simulation model of solar hot water system to investigate its performance. The annual thermal performance of solar hot water system is simulated with TRNSYS software as simulation platform. At the same time, under typical weather conditions, the variation of water temperature in the storage tank, the temperature of the inlet and outlet of the collector, the total solar radiation and the change of the heat collection efficiency are analyzed. The establishment of the simulation model of solar hot water system is of guiding significance for setting operating parameters of components and improving the comprehensive performance of solar hot water system. The present study provides theoretical guidance for the operation of the solar hot water system,
