ChillerHeaterPerformance:Electric:EIR Object In E+?
Hello All,
Could I use ChillerHeaterPerformance:Electric:EIR Object in energyplus as an Air to water Heatpump?
Thank you

No. The ChillerHeaterPerformance:Electric:EIR object is meant to define one chiller-heater module within a Central Heat Pump System. This central heat pump system is able to then provide cooling and heating either individually or simultaneously, but it is only set up to reject heat to water and not air.
If you want to model an air to water heat pump (useful heating/cooling of water by rejecting heat to air), I would recommend using the plant loop heat pump object (one for heating and one for cooling) that allows you to select air-cooled or water-cooled condenser. This feature was added to EnergyPlus in version 9.3.

Thank you,
In the Input output Reference (E+ 9.3): ChillerHeaterPerformance:Electric:EIR has water-cooled as the only valid condenser type!! But in E+, the ChillerHeaterPerformance:Electric:EIR object condenser could be water-cooled or air-cooled (E+ 9.3)?
For the centralHeatPumpSystem, the source loop inlet and outlet node name: what should be filled if I have an air condenser (evaporator)??
Yes, the chiller heater performance and central heat pump system will only allow water-cooled condensers. That is why I recommended a different object type for an air-cooled condenser that heats/cools water - the plant loop heat pump object.
