If you are a fairly advanced user comfortable with EMS, there is an object called Coil:UserDefined that can be used to roll your own model. See the chapter called User-Defined Component Models in the EMS Application Guide.

Subject: [EnergyPlus_Support] Modeling Condensing Unit in the DX system
Hi,
I am currently trying to model a condensing unit that is connected to a DX coil in EnergyPlus. I know that one way is to model it under Coil:Cooling:DX, specifying the 5 performance curves as input to model part load performance. However, unlike a packaged rooftop system, the performance data provided by the manufacturer for a condensing unit is a function of saturated suction temperature and ambient air temperature. Hence I would like to ask if there is any other ways to model the specification for such a condensing unit (as part of a DX system) in EnergyPlus?
Best,
Weili
