2020-05-20 05:11:57 -0500 | marked best answer | Fan electricity postprocessing Ideal Loads Air System results How to determine the total Fan energy through postprocessing the Outdoor and Supply Air Standard Density Flow Rates in output from a zone simulation with Ideal Air Loads? The outputs that I'm referring to are:
I thought that running the simulation to get hourly values for the flow rate I could then input these values into a simple equation to obtain the fan power: fanPressureRise*fanFlowRate/fanEfficiency (fanPressureRise and fanEfficiency being constant values) I'm working with Grasshopper Honeybee to run the EnergyPlus simulation. I’ve done a quick test, but I’m not sure my assumptions are correct. Would the total fan power be: FanSupply + FanOutdoor + FanExtract with:
This forum doesn't allow me to upload files yet, but I've posted screenshots and Honeybee script of the test in the Ladybug forum as well, here the link: link text I've been advised to post the question in Unmet, hope you can help me. Many thanks. |
