IMPROVEMENTS ON THE CAPABILITIES OF TRNSYS 15

摘要

This paper is about new features which where added to TRNSYS15 (Beckman, 2000) to improve its capabilities. For system simulations with TRNSYS15 now 6 new component libraries are available. Those Libraries include more than 160 new TYPES like solar, geothermal and HVAC components Also building simulations have been improved significantly. Thermally activated elements for heating and cooling are now integrated in the building model. Due to this simulations are now 5 times faster as with old finite element approach and setting up the system is now a matter of minutes instead of hours. Improvements on the solar radiation distribution within a zone and the possibility to have internal windows make it very easy to simulate double facades and air flow windows. For the detailed window model a new library with special windows based on manufacturing data provided by Pilkington, Saint Gobain, Interpane and Luxguard are now available. In order to speed up the performance of single zone building simulations significantly, the new interface TRNSYSlite for TRNSYS 15 was developed. Due to a variant manager and predefined control strategies it is possible to simulate several variants in less then half an hour. TRNSYSlite is a very useful tool for both experts and beginners.
