How does Honeybee create WSHP

[mrbro]

Hi there!

I think I found a bug (or maybe I am just confused) in how does Honeybee model the WSHP.

1. Here I am modeling a WSHP with central Cooling and Heating, without assigning the Air Details (bellow)
   

   
   
   And it is creating 5 DOAS and 1 HP Loop (Which is great)
   
   It is creating a HP loop with district Heating and Cooling
   
   

2. Here I am creating WSHP with central Cooling and Heating, with assigning air details (bellow)
   

   
   
   And it creates 5 DOAS and 5 HP loops.
   
   And the HP loops have Boiler and Cooling Tower
   
   

So my questions are:

1. Why even tho im creating central cooling and heating, it still creates 5 HP loops;
2. How exactly it understands to model weather it is district cooling/heating or boiler/tower? Since both cases have water rejection (0). Is it because of different COPs inputs for the heating and cooling?

I also believe I was using two different versions of HB at that time, but the questions above are still relevant.

Thank yoooouuuu

If you want a single loop then flatten the input for HBZones. It’s currently in 5 different branches and Honeybee creates a separate loop for each branch. This is not a bug and is happening by design.
