Re: [EnergyPlus_Support] how can I change the HOT WATER PLANT HW SUPPLY PUMP power in a HVAC Template System VAV

[Jason Kirkpatrick <jason.alan.kirkpatrick@xxxxxxxxx>]

Jose,

You can modify the pump power by changing the pump rated head in the HVACTemplate:Plant objects that you need to include to create the chilled water, hot water, and condenser water loops.

Pump Electric Power = Pump Volume Flow Rate  x  Pump Head /  Total Pump Efficiency

Refer to the EngineeringReference.pdf documentation that came with your install of energyplus for more detail.

Alternatively, once you have an expanded input data file that works, you could directly input the rated power consumption into the pump object and autosize the pump head. 

In order to accomplish this you will need to rename the file that end with .expidf to a file with name .idf and then you can edit and run the expanded idf like any other input file.

Hope this is of help.
