SHWWin: Freeware (Beta Stadium) for Universities and Schools for the Simulation of Solar Thermal Plants
Abstract
The simulation software SHWwin is being developed since 1993, first at the Institute of Thermal Engineering at Graz University of Technology, Austria and since 2009 at the Unit for Energy Efficient Buildings at the University of Innsbruck, Austria. In 2015 a new Version compatible with 64bit Operating Systems (Windows 7© and higher) was relaunched. Several new features like swimming pool, second domestic hot water store, English language, statistics on temperatures and pressure distribution, thermotrophic or back cooled collectors and others were implemented and a new layout of the graphical user interface was developed. Like the old Version also the new Version is available for free from the author to be used for education and research. SHWwin has a large number of sets of hydraulic layouts. As all parameters of e.g. heat stores (position of in/outlets, sensors) and control can be chosen freely, it is a nice tool to show students dependencies and relevance of the parameters and allows optimizing plants. Climate data can be taken from e.g. Meteonorm (2015) or any other source.
