[TRNSYS-users] Type 557 (ground heat exchangers) problem

[Jeff Thornton]

Hamid,

The new model replaces Type 557 and adds a few powerful features including the ability to have multiple occurrences of the model within a project and the ability to have multiple inlets into a radially stratified field.  This model will be featured in the GHP library of the new TESS Libs v18 package; a paid upgrade for users of the existing TESS Libraries.  The upgrade will include a lot of new components, new example projects, increased output reporting, and upgraded features in many models.

You are welcome to continue using Type 557 and all of your existing TESS components.  But if you’d like to use the new model, you’ll need to either purchase the new libraries when they come out later this fall or purchase this model directly.

It is not a free give-away as we have invested significant development time to add features to the existing Type 557 model.  If you are interested in purchasing the model before the TESS Library update, please contact us off-line and we can send you a quote.

>>> As you found out, Type 557 only allows once instance of this type in a TRNSYS simulation.  With several large projects requiring multiple borehole fields, we took quite a bit of time and re-worked Type 557 to allow multiple instances as well as add a few features; namely the ability to direct flow into and out of distinct radial regions in the field.  This becomes important when you use the model with radial stratification and wish to explore creative charging and discharging options with the field.  This new model will be featured in the new TESS GHP library when we release it for Version 18 in a few months - but we could make it available earlier if people are interested.  Please e-mail us off the mailing list if you are interested in learning more.
