Re: [EnergyPlus_Support] Accurately model a multi-compressor dx unit?





You can model up to 4 stages with the AirLoopHVAC:UnitaryHeatPump:AirToAir:MultiSpeed object.

I need to model a (6) compressor DX rooftop unit to compare the annual energy consumption with that of a comparable building that uses chilled water. Has anybody done something similar or have tips for how to model the multiple compressors?

The information available from EnergyPlus seems to say the program is limited to a high/low speed on a max 2 compressor unit. Am I misreading this?

Thanks ahead of time!
