I have a plant setup with vertical ground source and 2 HX in sequence to model Boiler heat addition and Fluid cooler heat extraction. The idea here is that the ground source would serve as much as it can and boiler and cooling tower are supplemental.
The first confirmation here is
-Is it a valid representation ? -as an alternate, If I sequence the bore field and the HX in parallel and select sequential in the plant order, it still wants to only account for 10-11% on the ground source and always runs either of the HX for boiler and fluid cooler. I am guessing the plant loop 'Sequential' and the combination of operation schemes that Open studio auto populates are counter acting each other? !
- Is it okay to over ride the peak gpm on the ground source to a higher flow rate? 400 gpm instead of a ~52 gpm ?
-The main problem with this loop is that the ground source comes out at much lower temperature than an expect 55-60 F under small flow rates in cooling season! The boiler is kicking on to maintain 55F! why is this ?
