Steam Jet Cooling Adopted for Trains and Buildings
What happened
In the early 1930s, steam jet cooling systems, which used steam ejectors to create a vacuum and evaporate water for cooling, gained popularity for air conditioning large buildings and passenger trains. The technology was later supplanted by mechanical compressors.
Literary impact
Steam jet cooling appeared in technical manuals and popular science writing, influencing the language of modernism. Poets like W.H. Auden referenced industrial cooling in their depictions of the machine age.
