This assumption, while appropriate for low temperature applications is not appropriate for high temperature collectors or for the heat transfer fluids that they typically employ. 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.

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. The TESS Utility Library is a collection of useful components for TRNSYS simulations including random number generators, water draw profiles, an 'event triggered' printer, a wind speed calculator, an economics routine, building infiltration models and many more.

It also features a wrap-around heat exchanger tank, aquastats, a heat pump water heater, and a zip water heater. In addition to the popular vertical cylindrical storage tank, the TESS Storage Tank Library also contains spherical, rectangular, and horizontally cylindrical tank models. From different theoretical and test-based (SRCC) collectors to collectors with different glazings, the TESS Solar Library has many to choose from. The TESS Solar Library contains 18 different solar collector components. TRNOPT may also be used to calibrate your simulation results to the data from the actual system. 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. 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. 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. Residential, commercial, and industrial HVAC components are all included. 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. 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.

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. The library includes simple PV models, PVT models, building integrated PV models, a PV array shading component, an equipment outage component, and lighting controls. 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. 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 TRNSYS17. 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. 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. 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.
