> After restarting flow to the solenoid yesterday in // cold return mode > TIC121 just refused to go lower than about 29K even when we closed CV155 > all the way. Tried various things, switching to // warm return, changing > opening of CV155, setting TIC121 to auto, even tapping TIC121. Finally > tried reducing flow to solenoid by reducing // warm return valves to about > 70% open to see if possible to cool just refrigerator a bit. > > TIC121 temp fell a bit and then inlet temperatures to solenoid began to > fall and solenoid slowly began to cool even though the mass flow to the > solenoid was reduced. Guess is that with solenoid homogeneusly at about 30K > there was not much resistance to flow so turbine massflow was starved just > enough to stall further cooling. > > After temps were on a good downward trend Doug switched to //cold return. > At about 16:00 yesterday I reduced CV155 to about 70% and waited a bit to > confirm that temps were falling and then left the system to cool until > later that evening.
