Can energyplus now simulate the energy consumption of air-water heat pump units?
EnergyPlus does not yet have an object to simulate a central air-to-water heat pump object. This is a high priority feature request, and is expected to be part of an EnergyPlus release in the next year.
As there are several modeling projects that require it, openstudio-standards has a method that mimics a central air-to-water heatpump with the PlantComponentUserDefined object in EnergyPlus. You can add this object to a plant loop, or add a whole HVAC system served by an air-source heat pump with the model_add_hvac_system method with AirSourceHeatPump as the main_heat_fuel.
thank you for your help
I am not clear as to how you use the openstudio-standards method to mimic a central air-to-water heatpump. Do you put the Prototype.CentralAirSourceHeatPump.rb file in a Lib directory of the OpenStudio installation directory? Then do you create a measure a require 'Prototype.CentralAirSourceHeatPump' statement to replace the PlantComponentUserDefined objects placed in the plant loops created in the OpenStudio user interface? I would really appreciate an example or detailed instructions as to how to use this method or a measure on the BCL. Thank you.
E+ has since added a central air-to-water heat pump object. I suggest you use that. The method in openstudio-standards is still using a PlantComponentUserDefined object to model the heat pump. If you want to add it to your model, you can use the "Create Typical Building from Model" OpenStudio measure on BCL.
