Individual Component Libraries

Recently, we have found ourselves asked to write single, quite complex TRNSYS components for clients and to build them into somewhat conventional systems; technology assessment tools if you will. In some cases, the client has been willing to allow us to share the components with the larger public. Somewhat inappropriate for inclusion in one of the TESS Libraries, we have chosen to offer these components for sale individually instead.

"Be All End All" Ground Coupling

Type Number: 1267

This models a multi-zone slab/basement/crawlspace conditions that communicates thermally with the ground. This model also allows the user to place fluid-filled pipes within or around the materials (such as pipes excavated under or around the foundation of the building) and connect the pipes together to form circuits. The component may also be used with storage tank models that are buried in the ground.

Ventilated Air Cavity Facade

Type Number: 1230

This component models an exterior wall where the outside surface is massive in nature (brick, terracotta, wood to a lesser extent) with a ventilated air gap behind it. In effect its an opaque solar collector. The back side of the air gap has small resistive layer and is then connected to a standard Type 56 wall for modeling the interior wall heat transfer. The model accounts for the absorption of solar energy on the exterior surface, long wave radiation exchange with the sky from the outside surface, convection to the ambient air, energy storage in the massive wall, conduction through the wall, radiation exchange through the air gap, convective exchanges to the air stream from both air gap surfaces, and conduction through the resistive layer. The model was derived from energy balances on the massive wall, the air stream, the exterior surface, and the interior surfaces.

VAV Air Handler

Type Number: 1249

The component models a VAV air handler for TRNSYS. The air handler contains a fan, heating coil, cooling coil and optional economizer and preheat coil. The model is intended to be connected to building models that can calculate sensible energy-rate-control loads (Type 56 etc.). The user should not specify the energy rate control dehumidification system, but rather should connect the moisture removal rate from the model as a negative moisture gain into the building model.

Exposed Basement or Parking Garage

Type Number: 1228

This component models a partially buried parking garage (3-sides buried and 1 exposed to the ambient).

Wetland Cell

Type Number: 979

Type 979 models the thermal behavior of one cell in a wetland waste water treatment system. The cell is essentially a rectangular parallelepiped that may be partially buried in the ground. It is assumed to be filled with some kind of porous media such as gravel and it is capped by a transparent or an opaque cover. Air and liquid may be pumped into and/or removed from the cell.

Ice Rink

Type Number: XYZ

This component models coils in either ground or concrete with a layer of ice on top. The ice rink may either be simulated for indoor or outdoor use.
This component was implemented into Type1267 Ground Coupling Component. Please refer to that component

Phase Change Material (PCM) Wall

Type Number: 1270

A phase change material wall that can be implemented with Type56/TRNBuild. Type1270 is designed to interact with Type56. The user is able to specify the physical properties of the PCM (density, specific heat, melting temperature, freezing temperature, and latent heat of fusion) or can enter a code to choose a particular commercially available "BioPCM" manufactured by Phase Change Energy Solutions. It should also be noted that Type1270 models a pure PCM. It should also be noted that Type1270 models a pure PCM. From a physical point of view, this means that the PCM is assumed to to go through its freeze/thaw process at constant temperature, to have a constant specific heat in the solid phase and to have a constant specific heat in the liquid phase.
