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)	::	OutdoorTDryBulb	Outdoor dry bulb air temperature `[°C]`
real(kind=dp),	intent(in)	::	OutdoorHumRatio	Outdoor air humidity ratio `[kgH₂O kgAIR⁻¹]`
real(kind=dp),	intent(in)	::	OutdoorPressure	Outdoor barometric pressure `[Pa]`
real(kind=dp),	intent(in)	::	InletTDryBulb	Indoor (inlet) dry bulb air temperature `[°C]`
real(kind=dp),	intent(in)	::	InletHumRatio	Indoor (inlet) air humidity ratio `[kgH₂O kgAIR⁻¹]`
real(kind=dp),	intent(in)	::	RatedCOP	Rated Coefficient Of Performance (COP) `[1]`
real(kind=dp),	intent(in)	::	RatedTotCap	Rated (total) system capacity `[W]`
real(kind=dp),	intent(in)	::	PartLoadRatio	Part load ratio (PLR). This is the actual cooling effect produced by the AC unit divided by the maximum cooling effect available - i.e. `PLR = (SensibleCoolingLoad / SensCoolingEnergyRate)` `[1]`
real(kind=dp),	intent(in)	::	RatedAirMassFlowRate	Rated air mass flow rate `[kg s⁻¹]`
real(kind=dp),	intent(out)	::	OutletTemperature	Actual (calculated) outlet air dry bulb temperature existing the cooling coil `[°C]`
real(kind=dp),	intent(out)	::	OutletHumRatio	Actual (calculated) outlet air humidity ratio existing the cooling coil `[kgH₂O kgAIR⁻¹]`
real(kind=dp),	intent(out)	::	ElecCoolingPower	Calculated electrical power consumed by the DX unit `[W]`
real(kind=dp),	intent(out)	::	SensCoolingEnergyRate	Sensible cooling power used to calculate the PLR. This is the maximum amount of sensible heat rate that the coil is capable of extracting from the indoor environment for the specified conditions. `[W]`
real(kind=dp),	intent(out)	::	LatCoolingEnergyRate
real(kind=dp),	intent(out)	::	TotalCoolingEnergyRate	Total cooling power of the DX unit (energy rate extracted by DX unit from the indoor environment) `[W]`
real(kind=dp),	intent(out)	::	TotalSensibleHeatOut	Total power rejected by the evaporator into the outdoor environment i.e. TotalCoolingEnergyRate + ElecCoolingPower `[W]`
