modelCoilHeader
Header for a heat exchanger register
Extends from Buildings.BaseClasses.BaseIcon (Base icon).
Information
Header for a heat exchanger coil.
This model connects the flow between its ports without modeling flow friction. Currently, the ports are connected without redistributing the flow. In latter versions, the model may be changed to define different flow reroutings in the coil header.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | nPipPar | Number of parallel pipes in each register | |
| Assumptions | |||
| Boolean | allowFlowReversal | true | = true to allow flow reversal, false restricts to design direction (port_a -> port_b) |
| Initialization | |||
| Modelica.Units.SI.MassFlowRate | mStart_flow_a | Guess value for mass flow rate at port_a | |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Fluid.Interfaces.FluidPort_a[nPipPar] | port_a | Fluid connector a for medium (positive design flow direction is from port_a to port_b) | |
| Modelica.Fluid.Interfaces.FluidPort_b[nPipPar] | port_b | Fluid connector b for medium (positive design flow direction is from port_a to port_b) |

Removed start value forport_b.m_flowto avoid an error because of conflicting start values if Buildings.Fluid.HeatExchangers.Examples.DryCoilDiscretized is translated using pedantic mode in Dymola 2016. This is for #426. -
