There are high heat loads in the spaces and therefore higher return air temperatures than the norm. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>When I remove the re-heat from the systems I have excessive unmet load hours (heating). I have specified “HEAT-SET-T” to activate the central heating coil. I also have cooling control set to “warmest” and heat control set to “coldest”. If I do not set the coil capacity it is still not meeting the loads. The only way I have been able to eliminate these unmet hours is by adding the re-heat back in or changing it to a multi-zone (MZS) system with all the same parameters. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If I model this scenario using the multi-zone system in eQuest to get around this would that be vastly different than VAV with no re-heat? Has anyone had this issue before? Any insight is appreciated.
