Central air-to-water gas absorption heat pump for domestic hot water
What is the best way to model a central air-to-water gas absorption heat pump for domestic hot water in a multi-family residential building using the OpenStudio application? I think the best option would be a HeatPump:PlantLoop:EIR:Heating object in a primary loop connected to the service water loop via a storage tank (OS:WaterHeater:Mixed with 0 kBtu/hr). Then, I would manually convert the electrical usage to gas usage in a spreadsheet outside of the OpenStudio. However, it seems that HeatPump:PlantLoop:EIR:Heating objects are still not supported in the OpenStudio application. I see that NREL's openstudio-standards includes a file called "Prototype.CentralAirSourceHeatPump.rb," but if that is my best option, how do I implement that as an OpenStudio measure in the OpenStudio application?
Do you mind sharing Prototype.CentralAirSourceHeatPump.rb as a file on this site?
If so I might be able to assist in converting that code to an OS measure.
Thanks, sashadf1. Here is a link to "Prototype.CentralAirSourceHeatPump.rb".
