evap fan speed control?

[knighty]

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?

Hi
I done it .

It was confection ( gummi candy -- strach mold )room

To dry it

Evaporators Surface area about 4 times

It has 2 Condenser one in the room and another one on the roof with actual capacity
Room's Condenser ( to cover cooling comes from Evaporators) with temperature control's for using desuperheat

Room temperature about 32 c

Evaporators has speed control's for fans

Room has extra circulation fan to remove humidity form gummi and strach molds

In winter time we had heating system ( steam Coil )

Also Compressor has a crankcase presuure control's to protect that .
