Airflow Rate Units

Hi,

I am modifying measure code to increase the capacities and airflow rates through the DX single speed cooling and heating coils of a single stage ASHP.

In the line below, I set the airflow rate through the coil(s) to the new, increased rate;

Airflow Percent Increase

I would like to print the units of value_after_flow to my log file in the runner.registerInfo() statement, but I don't know what they are.

Back of the envelope calculations tell me the units are probably m^3/s. Is this the case?

The method for the coil classes I am using is documented here: https://openstudio-sdk-documentation....

and here: https://openstudio-sdk-documentation....

but the airflow units are not displayed.

I confirmed by looking in the Input Output Reference that the units are indeed m^3/s.

Per input output reference: "The air volume flow rate, in m3 per second, across the DX cooling coil at rated conditions"

Since the OpenStudio SDK simply provides methods to modify EnergyPlus inputs, you should consult the EnergyPlus documentation for descriptions/units/etc. for the inputs themselves.

For example, here is the Rated Air Flow Rate documentation for the Coil:Cooling:DX:SingleSpeed object.
