Effective handling of air, water, and oil in ammonia refrigeration systems to conserve energy.

Author(s) : DANDAWATE L.

Summary

In our experience: Air, water and oil are the cause of most problems in refrigeration systems. Symptoms include: (1) Loosing capacity over the years. (2) Capacity problems during the summer. (3) Increased power consumption. (4) Higher service/maintenance costs. (5) Oil decomposing. (6) Unexplained behavior… Often the symptoms are addressed, not the root problem. What happens ? (1) Air: (a) Occupy condenser surface -> higher condensing pressure. (b) Blocking drainage of liquid. (c) Chemical reactions, oxidation of oil and metals. (d) Control problems due to air pockets (HP float valves). (2) Water: (a) Chemical reactions, breaking down of oil, corrosion. (b) Shift in saturated vapor pressure. (c) Lubrication problems (especially ball and roller bearings). (3) Oil: (a) Heat exchanger and/or evaporator fouling. (b) Cost of oil, filling and draining by authorized personnel, disposal. (c) Risk of ammonia leaks during draining.
