NOTE: During this operation, maintain water circulation through the chiller cooler and condenser vessels to prevent tube freeze-up. DISTILLING THE REFRIGERANT — Refrigerant vapor is transferred from the chiller cooler vessel or pumpout stor- age tank through the pumpout condenser , condensed to a liq- uid, and pumped to the chiller condenser vess[...]
