.Buildings.Fluid.HeatExchangers.ThermalWheels.Data.ASHRAE

Information

ASHRAE performance dataset for the variable-speed wheel model.

It is developed based on Figure 7 in ASHRAE (2024). However, the original data set was extrapolated to cover lower values of speed ratio, i.e. <= 0.2, by setting the heat exchange effectiveness corrections to 0 when the speed ratio is 0.
