New Features for Solar Thermal Simulation in Transol
Abstract
This paper seeks to highlight the recent developments in TRANSOL, including new systems, improvements in the TRNSYS simulation projects, new and updated components, extended and new databases, ease-of-use modifications to the graphical user interface and implementation of parametric runs. The result is a new version of the software package with improved performance and nine new schemes. The total number of schemes, i.e. basic configurations for solar thermal systems, is now 34 which allow to simulate up to 163 different configurations. New systems have been included to simulate the performance of solar thermal systems for covering heating demand of industrial processes, cooling of buildings or thermal demand in covered swimming pools. Updated and new systems have been included to design systems for covering domestic hot water (DHW) and heating demand, both in detached houses, multi dwelling buildings or collective buildings, like hotels, sport centres, etc. The changes introduced in how the TRNSYS projects have been built and the modifications in some key components result in a decrease of computation time: up to four or five times compared to the previous version. This gives the possibility to launch parametric comparisons of up to 25 runs within a reasonable computation time.
