<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:arial, helvetica, sans-serif;font-size:10pt"><div></div><div>So I determined why I was not getting any heating, and the resolutions perplexes me.</div><div><br></div><div> I am modeling an Air-to-Air heat pump, so in the air-side system --> Basics tab I selected "NO" for the field "WL/GS Ht Pump". In doing so, I get no heating out of the system. When I change the field to "YES" I now get heating. Attached are two images showing the field i am referring to, and showing that I have an air-cooled condenser. Does anyone know why this might be happening. I am worried that eQuest is treating my HP like a ground or water source HP instead of an air-to-air system. Any thoughts on the matter would be appreciated. By the way, I am using eQuest

<div style="font-family:arial, helvetica, sans-serif;font-size:10pt;color:#000000;"><div></div><div>I am trying to model a PVVT system, that uses an air-cooled heat pump for heating and cooling. For some reason, the system refuses to supply any heating. When I change the condenser type from air-cooled to water-cooled, the system WILL provide heat. Has anyone experienced problems like this, or has someone successful modeled a PVVT air-cooled heat pump? I have attached my IDF and PD2 file for review. </div><div style=""></div>
