Hi Friends there, I have logged on to this forum after so many years. I can not remember when I last logged in. Anyway I am back now. Can any body let me know the refrigeration system working of Flooded Natural Circulation System of the Contact Quick Plate Freezers. Particularly the HP Liquid Flood release tank installed inside the freezing chamber. Need to know the stages of working from HP Liquid receiver to the Suction port of the compressor for return cycle.
