Hello Honeybee Modelers,
TLDR: I want to model an earth tube that precools air before it reaches the DOAS in HB 1.2.0
I noticed that HB Legacy had an earth tube component which presumably was referencing this Zone Earthtube component in EP. From what I understand, this object works in a similar fashion to a natural ventilation object with mins and max’s between heating and cooling setpoints.
This is all well and good, however, it is not what I need, nor is it available in HB 1.2.0 (I think!)
Rather, I would like to model an earth tube at the beginning of the DOAS system, effectively precooling outside air before it hits the cooling coil. The simplest way I can think of doing this would be to approximate the air temp that is entering the DOAS (haven’t found a reference yet, but I’m sure it’s out there.) Do any of your know of a method to adjust the DOAS outdoor air supply temp manually in HB 1.2.0(3)? As with many of my HVAC related posts, I suspect the answer might lie with Ironbug…
