Node Mass Flow Variables[LINK]
The node mass flow variables merit a little more discussion. Six mass flow variables are defined at each node. They are: MassFlowRate, MassFlowRateMin, MassFlowRateMax, MassFlowRateMinAvail, MassFlowRateMaxAvail and MassFlowRateRequest. These variables hold loop mass flow rate information according to the following definitions.
MassFlowRate – this node variable holds the simulation mass flow rate for the current timestep. The remaining four variables serve as limits to MassFlowRate.
MassFlowRateMax, MassFlowRateMin – These node variables hold the maximum possible and the minimum allowable flow rates for a particular component. As such, they represent the “hardware limit” on the flow rate for the component.
MassFlowRateMaxAvail, MassFlowRateMinAvail – these node variables represent the loop maximum and minimum flow rate for the current configuration of the loop on which the component resides.
MassFlowRateRequest – this node variable applies only to plant and holds the desired mass flow rate for the current timestep. This stores a record of what flow was desired.
