Partial model of a rear door heat exchanger with coolant and air ports

Information

Partial model of a rear door heat exchanger (RDHx) with four fluid ports: two for the liquid coolant side and two for the air side.

The heat exchanger is modeled using Buildings.Fluid.HeatExchangers.DryCoilEffectivenessNTU with a cross-flow unmixed configuration. The performance data are provided through the record dat.

The coolant connections (port_a1 to port_b1) are included in this partial model. The air connections are left to the extending models, because the Buildings.Fluid.DataCenters.Racks.RearDoorHeatExchangers.Active model inserts a fan in the air path while the Buildings.Fluid.DataCenters.Racks.RearDoorHeatExchangers.Passive model connects the ports directly.
