Shen,<br>
There is a document called "Type557-DST_manual.pdf"
located in the ..\Trnsys16\Tess Models\Documentation\ directory that
provides an extensive description of how the Type557 model simulates the
interaction between the bore field and the surrounding ground.<br>
Kind regards,<br>

<blockquote type=cite class=cite cite="">Dear sir(s):<br>
I¡¯m a HVAC engineer working in China Academy of Building Research.
Recently, I¡¯m learning to use the Ground Heat exchangers model, which is
one part of TRNSYS models. There has a question that puzzled me for a
long time. So, I would appreciate that if you could give me some message
and instruction about it.<br>
In the Geothermal Heat Pump Library, after reading its menu, I still
could not understand very clearly that how does the boundary condition be
built up? Just taking <b>Type557a</b> for example. How does the boundary
condition be built up with only one borehole, and how about the
boreholes?<br>
Frankly speaking, my written English is not very well. So, if there are
any sentences confused you, please let me know. Thank you for you
time and consideration.<br>
I'm looking forward to receiving your message.<br>
Yours faithfully Shen<br><br>
