Air-Water heat pump in EnergyPlus?

Hi!,

I'm simulating a building that uses an air-water heat-pump to produce hot water. The Fan-coil and UTAs use hot water but is impossible to associate my heat pump with these systems.

The solution I have found is to use a boiler with efficiency 1 and calculate the real consumption using the COP of the heat pump.

The problem is that I need use Jeplus to calibrate the COP but its not an input variable.

Is there a way to define a hot water production system to which I can introduce the COP of my heat pump?

Thank you!

You can use the HeatPump:PlantLoop:EIR:Cooling and HeatPump:PlantLoop:EIR:Heating objects for an air-to-water heat pump. From the documentation:

Beginning with version 9.1, an EIR-formulated heat pump model was added. This heat pump can be operated as a water-source object with the source-side connected to another plant loop, or as an air-source object with the source-side interacting with the outdoor air. This formulation allows the user to enter curves for specifying the capacity and energy usage in a more generic way, allowing the curves to be applicable to a wide variety of components. With the original equation fit model, the curve form was locked in to a specific set of linear coefficients. With the new form, the curve can be a quadratic function of temperatures, or an even more generic lookup table.

The implementation of this capability occurred here.
