Model that demonstrates the use of a heat exchanger with
condensation and with autotuning PI feedback control (intentionally
designed to fail)
This example is identical to
Buildings.Fluid.HeatExchangers.Examples.WetCoilCounterFlowPIControlAutoTuning
except that the configuration is intentionally designed to cause a
failure, used to test error-handling mechanisms.
The autotuning is triggered twice.
- The first one occurs at 100 seconds and it completes
successfully, with the tuned PI parameters taking effect at
157 seconds.
- The second one occurs at 2100 seconds. However, the
tuning process yields negative control gains, thus the autotuning
fails and a warning is issued. The PI gains remain unchanged from
the previous tuning.
