Nodes of different colours represent the following:
Solid arrows point from a parent (sub)module to the submodule which is descended from it. Dashed arrows point from a module being used to the module or program unit using it. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Nodes of different colours represent the following:
Solid arrows point from a procedure to one which it calls. Dashed arrows point from an interface to procedures which implement that interface. This could include the module procedures in a generic interface or the implementation in a submodule of an interface in a parent module. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

SUBROUTINE SizeWrapper(WrapperNum)
! SUBROUTINE INFORMATION:
! AUTHOR Yunzhi Huang, PNNL
! DATE WRITTEN Feb 2013
! MODIFIED na
! RE-ENGINEERED na
! PURPOSE OF THIS SUBROUTINE:
! This subroutine is for sizing all the components under each 'CentralHeatPumpSystem' object,
! for which capacities and flow rates have not been specified in the input.
! METHODOLOGY EMPLOYED:
! Obtains evaporator flow rate from the plant sizing array. Calculates reference capacity from
! the evaporator (or load side) flow rate and the chilled water loop design delta T. The condenser
! flow (or sourse side) rate is calculated from the reference capacity, the COP, and the condenser
! loop design delta T.
