A friend of mine that has industrial refrigeration experience only called me about an ice machine that he has been working on at his deer camp. I drove down there Sat. evening and this is what I found:
suction pressure: 20#
Disharge: 100# (cond. fan was running)
ambient room temp: 83Deg F
subcooling:11 Deg F
superheat: 56 Deg F
recirculating water temp: 80 Deg F
Based on the superheat, I think it is the TXV. I unplugged
the water pump to see if it would start frosting up and it didn't; the superheat went down a little but not much. I expected the suct. press. to drop quit a bit, but it stayed right at 20#. Dish press. dropped a little. The
hot gas line didn't feel like it was leaking by, just slighty warm past the solenoid. The filter is vertical and the liq. line loops down and into the bottom of the TXV(TXV is Horizontal) then exits where I had expected there to be an adjustment stem...is there no way to set this type? What do you think I should do, replace the TXV?
Thanks for any input...
