Graph Key

Nodes of different colours represent the following:

Solid arrows point from a submodule to the (sub)module which it is descended from. Dashed arrows point from a module or program unit to modules which it uses. Where possible, edges connecting nodes are given different colours to make them easier to distinguish in large graphs.

Arguments

Type	Intent		Name
real(kind=dp),	intent(in)	::	OutdoorDryBulb	Outdoor (environmental) air temperature [°C]
real(kind=dp),	intent(in)	::	OutdoorHumRatio	Outdoor (environmental) air humidity ratio [kg/kg]
real(kind=dp),	intent(in)	::	OutdoorPressure	Outdoor (environmental) pressure [Pa]
real(kind=dp),	intent(in)	::	InletDryBulbTemp	Actual inlet air temperature [°C]
real(kind=dp),	intent(in)	::	InletAirHumRat	Actual inlet air humidity ratio [kg kg-1]
real(kind=dp),	intent(in)	::	RatedCOP	Rated COP [1]
real(kind=dp),	intent(in)	::	RatedTotCap	Rated capacity [W]
real(kind=dp),	intent(in)	::	PartLoadRatio	Part load ratio (PLR). This is the actual heating produced by the AC unit divided by the maximum heatng available - i.e. `PLR = (SensibleHeatingLoad / TotalHeatingEnergyRate)` `[1]`
real(kind=dp),	intent(in)	::	RatedAirMassFlowRate	HVAC air mass flow rate [kg/s]
real(kind=dp),	intent(out)	::	OutletAirTemp	Actual outlet temperature [°C]
real(kind=dp),	intent(out)	::	OutletAirHumRat	Actual outlet humidity ratio [kg/kg]
real(kind=dp),	intent(out)	::	ElecHeatingPower	Electrical power consumed by the DX unit [W]
real(kind=dp),	intent(out)	::	TotalHeatingEnergyRate	Total energy supplied by the DX unit [W]
real(kind=dp),	intent(out)	::	TotalSensibleHeatOut	Total sensible heat removed by the evaporator[W]
