evap fan speed control?
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?

Re: evap fan speed control?
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 .Last edited by mbc; 05-10-2022 at 07:14 AM.
