there's plenty of info/talk about condenser fan speed control, inverter driven compressors etc..

but I never see anything about evap fan control on commercial stuff?

small split air con units are the only thing I can think of that controls evap fan speed


I've been thinking about this for a while... as long as liquid and suction pressures are within range you could (pretty much) just use room temperature to control evap fan speed?

evap capacity is pretty much just linked to air on temp

so as room temp drops, why not increase fan speed?
