"Invalid Component" Error using AirLoopHVAC:UnitarySystem

asked 2018-06-08 14:21:22 -0500

updated 2018-06-11 07:25:47 -0500

I'm stuck on this error shown below:

    ** Severe  ** During AirLoopHVAC:UnitarySystem Input, Invalid Component Type input=COIL:COOLING:DX:SINGLESPEED
   **   ~~~   ** Component name=ACDXCOIL 1
   **   ~~~   ** Occurs in AirLoopHVAC:UnitarySystem = MINISPLITUNIT

This does not make sense as the I/O manual and IDD both clearly state this coil type is a valid choice for the unitarysystem object.

Additional context: trying to model a residential minisplit system (no outside air), EnergyPlus 8.9.0 on windows

Any help would be greatly appreciated, thanks!

Visual inspection of the components shows correct implementation. However, if you search for the coil name it only appears once. One component uses a 1 (one) in the name (ACDXCoil 1) and the other uses the lowercase letter L. So it's not the coil type that is the problem, it's a misspelled coil name.

   MiniSplitUnit,           !- Name
   Coil:Cooling:DX:SingleSpeed,  !- Cooling Coil Object Type
   ACDXCoil 1,              !- Cooling Coil Name

   ACDXCoil l,       !- Name

Thanks! That fixed it.
