I am trying to add a DX cooling coil to an air loop using an OpenStudio measure. It all works very well when I use "OS:Coil:Cooling:DX:VariableSpeed". The coil does indeed show up on the Air Loop HVAC diagram, together with heating coil, variable speed fan, outdoor air system and energy recovery ventilator, all of which also get added in the same OpenStudio measure. At this point, I am not adjusting any parameters yet, just trying to compose the general topology.
However, when I comment out the "OS:Coil:Cooling:DX:VariableSpeed" creation and uncomment out the "OS:Coil:Cooling:DX:MultiSpeed" creation in that measure, the cooling coil no longer shows up in the Air Loop HVAC diagram, though all other components still show up. Also, while the .OSM file with the "OS:Coil:Cooling:DX:VariableSpeed" shows corresponding OS:Connection entries, the .OSM file with the "OS:Coil:Cooling:DX:MultiSpeed" does not, even though the "OS:Coil:Cooling:DX:MultiSpeed" entry itself does show up.
It is as if this call generates the connections
cooling_coil = OpenStudio::Model::CoilCoolingDXVariableSpeed.new(model)
but this call does not?
cooling_coil = OpenStudio::Model::CoilCoolingDXMultiSpeed.new(model)
I'd appreciate any thoughts.
