Dear Anderson,<div><div><br></div><div>The example file (in EnergyPlus 8.0) is indeed what I was looking for. </div><div>This has AirLoopHVAC for DOAS and VRF system, which has separate coils assigned for each system controlling temperature and humidity. <br>
Great!</div><div><br></div><div>Thank you!</div><div>Sang Hoon</div><div><br><br><div class="gmail_quote">On Mon, Jun 3, 2013 at 4:42 PM, Anderson Letti <span dir="ltr"><<a href="mailto:anderson.a.letti@gmail.com" target="_blank">anderson.a.letti@gmail.com</a>></span> wrote:<br>

Hi Bldg-Sim Group,<div><br></div><div>I am working on variable refrigerant flow (VRF) system modeling using EnergyPlus to understand energy savings compared to other conventional systems. </div><div><br></div><div>For VRF modeling, I utilized the example file "VariableRefrigerantFlow_5Zone.idf". This example uses outdoor air mixer in each VRF indoor unit for the supply air which goes through cooling and heating coil to the zone inlet node. </div>
<div><br></div><div>But, a typical VRF system practice uses a separate DOAS system to reduce cooling and heating load in the VRF side only recirculating return air to be conditioned. </div><div><br></div><div>I am trying to add DOAS in the VRF modeling. The problem is that HVACTemplate:DOAS (in EnergyPlus 7.2 or 8) does not support this. </div>
<div><br></div><div>Is there anybody who did VRF system modeling with adding DOAS?</div><div><br></div><div>Thank you!</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>--</div><div>Sang Hoon Lee, Post-doc</div>
