modelBypassDampers

Information

Example for the model Buildings.Fluid.HeatExchangers.ThermalWheels.Latent.BypassDampers.

The input signals are configured as follows:

• The operating signal uRot changes from false to true at 72 seconds.
• The supply air temperature TSup changes from 273.15 + 30 K to 273.15 + 40 K during the period from 60 seconds to 120 seconds. The exhaust air temperature remains constant.
• The bypass damper position uBypDamPos changes from 0 to 0.2 during the period from 200 seconds to 360 seconds.
• The supply air flow rate and the exhaust air flow rate are constant.

The expected outputs are:

• The sensible heat exchanger effectiveness epsSen and the latent effectiveness epsLat are 0 at the beginning. They become positive at 72 seconds and keep constant until 200 seconds. After the 200 seconds, both epsSen and epsLat decrease.
• Before 72 seconds, the temperature of the leaving supply air is equal to TSup. Likewise, the temperature of the leaving exhaust air is equal to that of the entering exhaust air temperature. The temperatures of the leaving supply air and the leaving exhaust air follow the change of TSup during the period from 72 seconds to 200 seconds. After 200 seconds, the leaving supply air temperature increases and the leaving exhaust air temperature decreases.
