Preface: Past, Present, and Future of Ejector Refrigeration

The history of ejector refrigeration is tightly nestled in the broader history of refrigeration. When the steam jet chiller first appeared, many different refrigeration cycles had already been used for both refrigeration and air conditioning purposes. However, the steam jet refrigerator had the advantage that it could run using exhaust steam from any source (steam engines, industrial or chemical processes, etc.). Therefore, starting in 1910, steam jet refrigeration systems found use in breweries, chemical factories, theatres, ships, and trains. Despite the promising start, the use of supersonic ejectors for refrigeration applications almost ended when Thomas Midgley Jr. and his associates introduced the first synthetic refrigerants during the 1930s. These ga
