[TRNSYS-users] Two boreholes and one heat pump installation

[David BRADLEY]

Matthieu,
   You are correct that you can have only one instance of Type557 in a 
project. We have a Type1557 that I can send you; it is simply a copy of 
Type557 but renumbered. This will allow you to define two bore "fields" 
but keep in mind that there will be no thermal interaction between the 
two bores apart from the impact of the fluid passing through the pipes. 
In other words the bores won't know of each others' existence.  Please 
simply send me the contents of your user17.id file (please don't copy 
the whole list!) and I'll get you the additional files needed.

   As to your other question; the data file is not specific to one or 
another heatpump. It is quite generic and can be used to model the 
performance of any number of heat pumps and of heat pump sizes. If you 
have a specific heat pump in mind then I would recommend that you go the 
manufacturer's website and look for the performance data specific to 
that machine. Once you normalize its data you will probably find that 
the data file looks quite similar to the generic file.
Kind regards,
  David
