Information

Model of a sensible heat recovery wheel, which consists of a heat exchanger and two dampers to bypass the supply and exhaust airflow, respectively.

This model does not require geometric data. The performance is defined by specifying the part load (75% of the nominal supply flow rate) and nominal sensible heat exchanger effectiveness. This operation of the wheel is configured as follows.

• If the operating signal uRot=true,
  • The wheel power consumption is constant and equal to the nominal value.
  • The heat exchange in the heat recovery wheel is adjustable via bypassing supply/exhaust air through the heat exchanger. Accordingly, the sensible heat exchanger effectiveness is calculated with Buildings.Fluid.HeatExchangers.ThermalWheels.Sensible.BaseClasses.Effectiveness.
• Otherwise,
  • The wheel power consumption is 0.
  • In addition, there is no heat transfer, i.e., the sensible heat exchanger effectiveness of the heat recovery wheel is 0.
