simulation software

This technical report is a deliverable of Task 38, Subtask C within the framework of the International Energy Agency’s Solar Heating and Cooling Programme. It describes both existing and developing simulation tools and models used for solar cooling applications.

Air collector systems of Grammer can now be simulated and planned with the new version 5.0 of T*SOL Pro, the dynamic simulation programme for the design and planning of solar thermal systems, developed by German company Valentin Software. The programme is the result of a close collaboration with German air collector manufacturer Grammer Solar.

This thesis from 2009 describes the design and testing of a solar thermal collector simulator. The main objective of this study is to assist research and development of future projects that incorporate a small solar collector array. An in-depth description is provided covering both the hardware and software needed to control the power output and the status of the simulator.

Due to the growth in the solar thermal industry, there is significant need for training in solar thermal system design. This document goes over the usage of simulation software in education. It allows a trial and error approach and motivates the students to make near-to-reality experiences with good and bad heating systems.

Solar cooling is a promising new field of application for solar thermal technology. A new version of the simulation software Polysun will be published in April. It will not only be able to design solar thermal systems but also solar powered cooling plants that work with compression coolers or fan coils. A version that also contains a simulation model for absorption chillers is scheduled for the summer months. Polysun is offered in Chinese, Czech, English, French, German, Greek, Italian, Portuguese and Spanish.
