Title: Cavalier USS-8-64 evaporator airflow direction ??
Post by: riv187 on July 29, 2021, 02:54:30 pm
I know some things are changed inside like it now has a digital thermostat. I noticed the evaporator fan ,that sits atop the square evap coil,,It pushes downward. the airflow hits bottom and has to deflect upward ,,only to return through back rectangle opening of the fan hood. This didn't seem correct,,so I pulled off the hood as shown and looked at the specs of motor and fan. Its a GE 4w 1550 rpm CCW.
 Is this the correct flow direction?? pushing down at the tray????? It seems to me it should go up the back towards top and fall down to tray. This would require either a different fan blade or motor that goes clockwise,,,,but the motor would be sucking instead of pushing air,,,,less efficient I'd think?

 I also checked the condensor fan to compare,and it pushes,,is a Morrill Motors 1450 rpm 6W cw -clockwise.
Does my machine have correct fans for watts, and direction? ?
Both have 5 blade fans.
 Thanks for help!

The evaporator fan should pull “up” from the bottom of the tank ( tray) & push out the back of the deflector & up the rear wall behind the bottle shelves,   The condenser ( compressor) fan should pull air first through the condenser coils (radiator) & push it back over the compressor itself.
