Hi. I am trying to model a condo building on eQuest where each suite has a water source heat pump connected to a central loop with boilers and a cooling tower to maintain the loop temperature.
So I have set up a central WLHP water loop with a boiler and a fluid cooler, and for all the suites I've assigned "Water Loop HP" as the system type and selected the WLHP loop as the condenser loop.
The problem is my heating energy use on the report is way too low. When I dug into the reports I'm finding out that for whatever reason, while the loads of the actual spaces are calculated, there's no HVAC heating use at all. LS-A shows the space peak loads, but the boiler for this loop in PS-C show no usage, and the Circulation Loop in PS-D show no heating usage (but it does show cooling usage). Another thing that's worrying is the % of hours outside throttling range is 99.99%.
Does anyone know what I should be looking at to fix this?
Thanks.
-John
