How to model an air source heat pump for small commercial space?

edit

I'm searching everywhere to find an ASHP to add as the HVAC for a small commercial space. I'm finding "Multi Speed HP Air to Air", but the heating input is on natural gas and it can't be changed. Tried searching on BCL, too, but I can't find it anywhere. I imagine lots of people are modeling ASHP, so where is the library/component?
