Issue overview

In the object AirConditioner:VariableRefrigerantFlow, fields:

41 !- Piping Correction Factor for Length in Cooling Mode Curve Name
44 !- Piping Correction Factor for Length in Heating Mode Curve Name

point to a curve or lookup table. Per the Input/Output reference (https://bigladdersoftware.com/epx/docs/24-2/input-output-reference/group-variable-refrigerant-flow-equipment.html#field-piping-correction-factor-for-length-in-cooling-mode-curve-name) the input (independent variable) for these curves should be in units of length.

When unit type "Distance"

Table:IndependentVariable,
...
Distance, !- Unit Type

is specified for these curves, EnergyPlus produces the following error:

**** Severe ** Table:IndependentVariable "TBL LOOKUP P72TNU/YNU_PCFC_FN_L-INPUT_0": Unit Type [Distance] is invalid**

Details

Some additional details for this issue (if relevant):

• Platform (Operating system, version) Windows 11
• Version of EnergyPlus (if using an intermediate build, include SHA) 24.2
• Unmethours link or helpdesk ticket number

Inputting a unit type of "Dimensionless" for this field will eliminate the error.
