RE: [EnergyPlus_Support] Water to Air heat pump

["bruno" <bbueno@xxxxxx>]

Hello,

 

I?m trying to model a hydronic system fed by a heat pump condensated by air.
I don?t find any water to air heat pump at the plant equipment objects. I
would like to know how I can do this and if there is any example file
related available.

 

Thanks in advance,

 

Bruno Bueno

Asunto: Re: [EnergyPlus_Support] Enthalpy reference temperature - PCM

 

My understanding is that the model is computing changes in enthalpy, so the 
reference for zero enthalpy should not matter. For example, if you were to
add 
1000 to every enthalpy value, but keep the same temperatures, you should get

the same result. 

I will forward this to the Conduction Finite Different model developer for 
clarification.
