When you run the model, you even get different energy use results for each cooling plant (GSHP) when you have two identical rooms with one assigned to each cooling plant (since the temperature of the ground loop is different based on TLoop Ent Bldg). This implies that there are two separate loops, otherwise the one loop would have two different entering temperatures simultaneously.</span> <br><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>Catalina, does that address the question that you asked?</span> <br><b><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'><br>Alex N.

TRACE 700 can only model a single ground heat exchanger per alternative and system coils (e.g. cooling and heating coils) are assigned to a plant, rather than an individual piece of equipment. In your scenario, you may have one or two ground loops but you'll only be able to model a single loop in the alternative. This limitation prevents you from modeling the systems independently.<br><br>If you create two ground source heat pump pieces of equipment, you'll still need to assign these to a single plant. Doing so does not allow you to independently operate each plant based upon system coil load because cooling and heating coils are assigned to plants rather than equipment. The sequencing options will not help you in this instance.<br><br>To model this system, you'll need to make a ground source heat pump system as shown in the User's Manual. You can make a single cooling plant (water source heat pump equipment type) and modify the energy rate and ground loop information as you desire. You may wish to use a composite energy rate the best represents all heat pumps on the ground loop(s).<br><br>I suspect that the information you received from C.D.S. is correct in that you can model two separate heat pump plants, but you cannot model two separate ground loops in a single file.<br><br>Regards,<br>Eric Sturm<br>Applications Engineer<br>Trane Commercial Systems<br>Ingersoll Rand<br>3600 Pammel Creek Rd<br>La Crosse, WI 54601<br><br>Office: +1.608.787.3736<br>Fax: +1.608.787.3005<br>Email: esturm@trane.com<</span><a href="mailto:esturm@trane.com"><span style='font-size:10.0pt;font-family:"Courier New"'>mailto:esturm@trane.com</span></a><span style='font-size:10.0pt;font-family:"Courier New"'>><br>Website: </span><a href="www.trane.com"><span style='font-size:10.0pt;font-family:"Courier New"'>www.trane.com</span></a><span style='font-size:10.0pt;font-family:"Courier New"'><br><br>From: </span><a href="mailto:trace-users-bounces@lists.onebuilding.org"><span style='font-size:10.0pt;font-family:"Courier New"'>trace-users-bounces@lists.onebuilding.org</span></a><span style='font-size:10.0pt;font-family:"Courier New"'> [</span><a href="mailto:trace-users-bounces@lists.onebuilding.org"><span style='font-size:10.0pt;font-family:"Courier New"'>mailto:trace-users-bounces@lists.onebuilding.org</span></a><span style='font-size:10.0pt;font-family:"Courier New"'>] On Behalf Of Caballero, Catalina<br>Sent: Tuesday, November 27, 2012 2:57 PM<br>To: 'trace-users@lists.onebuilding.org'<br>Subject: [Trace-users] Multiple Ground source Heatpump in one alternative<br><br>Good afternoon,<br><br>I'm trying to find out a way to model 2 ground source heat pumps in an alternative.
