MDW's profile - activity

The model_add_hvac_systemmethod is called, which requires input thermal zones to be the thermal zone object rather than

Ah right, thanks for the pointer. I'm now using the following thermal_zone = model.getThermalZoneByName(thermal_zone_nam

No, the measure does not call the mentioned method. It's possible that a method I'm calling from the openstudio standard

Hello, I am writing an ASHP measure on Ruby to be used in Open Studio and am encountering an error. The error file reads as the following:

Seems like the DX cooling coil doesn't know where to go because the nodes are not defined. Is there a method that can define the nodes for the system in a standardized way? As context, I initialized a new cooling coil with the following lines (similar for heating coil):

new_cooling_coil = OpenStudio::Model::CoilCoolingDXSingleSpeed.new(model)
air_loop_hvac_unitary_system.setCoolingCoil(new_cooling_coil)

Thank you!
