Each of the component libraries comes with a TRNSYS Model File (*.tmf) to use in the Simulation Studio interface, source code, and an example TRNSYS Project (*.tpf) that demonstrates typical uses of the component models found in that library. With the release of the TESS Libraries version 17.0, over 90 new models with many new examples have been added from the previous version 2.0.
The following are the 14 available TESS Component Libraries for TRNSYS17:
1.Application Components
The TESS Applications Library is an assortment of scheduling and setpoint applications that use the TRNSYS Simulation Studio plugin feature.
2.Controller Components
The TESS Controllers Library contains numerous controllers for practically any TRNSYS simulation. 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.
3.Electrical Components
The TESS Electrical Library has components for solar photovoltaic (PV) and combined solar thermal (PVT) modeling in TRNSYS. The library includes simple PV models, PVT models, building integrated PV models, a PV array shading component, an equipment outage component, and lighting controls.
4.Geothermal Heat Pump (GHP) Components
The TESS GHP Library is not only host to extensive ground heat exchanger models (horizontal multi-layer ground heat exchanger, and the vertical heat exchanger), but also to buried single and double pipes, and various heat pump models as well.
5.Ground Coupling Components
The TESS Ground Coupling Library features components compute the energy transfer between an object (building slabs, basements, buried thermal storage tanks, etc.) and the surrounding ground.
6.HVAC Equipment Components
With over 60 different components, the TESS HVAC Library is a far ranging group of components for modeling anything related to heating, ventilation, and air conditioning of buildings.
7.Hydronics Components
The TESS Hydronics Library contains a variety of fans, pumps, valves, plenums, duct and pipe components that are essential for working with fluid loops in a TRNSYS simulation.
8.Loads and Structures Components
The TESS Loads and Structures Library contains alternatives to the standard TRNSYS building model including a synthetic building (load curve generator), a simple multizone building, and methods for imposing precalculated building loads (generated by TRNSYS or by other software) onto a TRNSYS system or plant simulation.
9.Optimization Components
The TESS Optimization Library (also known as TRNOPT) is a tool that couples the TRNSYS simulation with the Lawrence Berkeley National Laboratory's GenOpt program for the minimization of a cost or error function.
10.Solar Collector Components
The TESS Solar Library contains 18 different solar collector components. From different theoretical and test-based (SRCC) collectors to collectors with different glazings, the TESS Solar Library has many to choose from.
11.Storage Tank Components
In addition to the popular vertical cylindrical storage tank, the TESS Storage Tank Library also contains spherical, rectangular, and horizontally cylindrical tank models.
12.Utility Components
The TESS Utility Library is a collection of useful components for TRNSYS simulations including random number generators, water draw profiles and many more.
13.Cogeneration (CHP) Components
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..
14.High Temperature Solar Components
Many of the models in the standard TRNSYS and TESS Solar Collector Libraries assume that the specific heat of the collector's working fluid is constant.
