The TESS Electrical Library has components for solar photovoltaic (PV) and combined solar thermal (PVT) modeling in TRNSYS. Components range from a simple thermostat controller to a complex multi-stage differential controller with minimum on and off times, and from a tempering valve controller to an outside air reset controller. The TESS Controllers Library contains numerous controllers for practically any TRNSYS simulation. TESS has used them to simulate the thermodynamics of the beer brewing process and to model a biomass power plant. These components may be used to simulate different cogeneration or trigeneration systems at different scales. The TESS Cogeneration (also known as the Combined Heat and Power or CHP) Library features many steam system components: pumps, valves, superheaters, desuperheaters, turbines, etc. These components are extremely useful for creating daily, weekly, monthly schedules, normalized occupancy, lighting, or equipment schedules, and setpoints for thermostats. The TESS Applications Library is an assortment of scheduling and setpoint applications that use the TRNSYS Simulation Studio plugin feature. The following are the 14 available TESS Component Libraries for Trnsys18.

With the release of the TESS Libraries version 18, nearly 100 new models have been added from the previous version (v17). Each of the component libraries comes with a TRNSYS Model File (*.tmf) to use in the Simulation Studio interface, source code, documentation, and an example TRNSYS Project (*.tpf) that demonstrates typical uses of the component models found in that library. The components contained in these libraries represent the best of our in-house Types.

Through our consulting projects at TESS, we have developed well over 500 TRNSYS components.
