Dear Otto Schwieterman,<br> I am using Visual DOE 4.1 for energy simulation and i have followed the techinque told by you for modelling VRV systems . I created a Air to Air heat pump in my heating tab .But when i created it ,it is asking the COP of the heat pump should i enter the VRV COP in the heat pump COP?? in heating tab , or in my cooling tab it is also asking for DX system COP? where should i enter my VRV system COP?<br>
<br><br>Also the option to make compressor as one two or variable speed is comming in my air to air heat pump is it ok.<br><br><br>I look forward for your valuable response.<br><br>Thanks<br>Sambhav Tiwari.<br>
