Modelling of Low-Temperature Solar Thermal Systems with Modelica

摘要

A new Modelica library named Soltermica is presented. It contains models of solar thermal systems such as solar collectors, hot-water storage tanks, boilers, and heat exchangers; and models of climatic conditions, including solar irradiance. These models are intended for aiding in the design, optimization and control of solar water heating systems. The validation has been performed comparing the simulation results obtained from Soltermica and ACSOL/PACSOL, a TRNSYS-based tool. Soltermica has been developed using the OpenModelica modelling environment and is freely available at https://github.com/gheralb/Soltermica.
