Hope someone can answer my questions about my boat refer.
It is an R 12 system with two cold plates in series.
One Danfoss tev at the inlet of the first plate (brine solution) and the sensing bulb at the outlet of the 2nd (antifreze solution)
Sanyo 508 compressor with seawater condensor,sightglass receiver and fiter drier and finally a suction accumulator.
I recently noticed the suction accumulator and line ot the compressor was frosting at start up.
At start up low pressue is 20lb and high presure is 140 lb.
within two minutes low pressure drops to 10" hg and high pressure is145lb . Ambient about 70F.
I called a tech out to the boat he adjusted the super heat and said it was fine.The compressor is still running in a vaccumn.
The system has run fine for 8 years why would the super heat
suddenly need adjustementand is it ok to run a vaccumn?
Thanks Terry.
