Direct Expansion Feed in Dual Stage Ammonia Plants: Operatin
Direct Expansion Feed in Dual Stage Ammonia Plants: Operating Experiences in a Large Refrigerated Distribution Center (2006)-The performance and reliability of ammonia liquid overfeed systems are well known and documented. Documented operating experiences with large-scale, low-temperature, extended-surface, galvanized-steel air coolers designed for direct expansion feed are less frequent. The paper describes such an experience in a refrigerated distribution center in Queensland, Australia, and details the methodology and the computerized techniques employed in the design, circuiting, and performance prediction for such coolers. The evolution of the electronic expansion valve control algorithms and the operating experiences on which they are based are presented, as well as practical issues relating to oil management.
