Refrigeration Applications: Liquid Recirculation Systems

Ammonia Refrigeration

Liquid recirculation systems, often called liquid overfeed systems, were introduced to the industry in 1925 when a patent was issued to the York Corporation. As with many great ideas, it took between 35 and 40 years before it became common practice in the industrial refrigeration area. Even though there has been some very astute research regarding liquid recirculation, there seems to be as many designs as there are designers.
