modelSingleCircuitMultipleCircuitFiniteDifference
Model that tests the radiant slab with multiple parallel circuits
Extends from Buildings.Fluid.HeatExchangers.RadiantSlabs.Examples.SingleCircuitMultipleCircuitEpsilonNTU (Model that tests the radiant slab with multiple parallel circuits and epsilon-NTU configuration).
Information
This example compares the results of two models of a single circuit that are arranged in parallel, versus a model that directly implements two parallel circuits. Both configurations have the same mass flow rate and temperatures. For simplicity, a combined convective and radiative resistance which is independent of the temperature difference has been used. The model is exposed to a step change in pressure, which causes forward and reverse flow.
