[Bldg-sim] loop to loop heatpump in equest

[Anthony Hardman]

Would the following get you close enough (ignoring the DOAS side)?

 

1)      Specify a water-air HP system

2)      Zero out the fan energy

3)      Factor the load side pumping energy into the EIR of the HP

a.       Alternatively, you could add your load side pump energy to the
source side pump

 

Obviously there's limitations either way and I've never tried this, just
thinking out loud.  Certainly someone else out there can comment who has
attempted this?

Hi All, 

 

I am trying to model a building with water-to-water heat pump connected to
ground HX and 4-pipe AHUs with induction unit at the terminal. 

I have specified induction unit at the terminal, to model active chilled
beams, with a dedicated outdoor air unit. But with this configuration on
airside I am not able to attach the water to water heat pump to any
condenser water loop on the water side. Is there a way I can model GSHP
serving active chilled beams in equest?

 

Thanks in advance.
