Steam jet cooling
In the contemporary world, Steam jet cooling has acquired an importance that has transcended borders and has become a topic of interest for a wide spectrum of society. Its relevance is manifested in different areas, from politics and economics to culture and entertainment. Steam jet cooling has captured the attention of experts, academics, critics and the general public, generating debates, reflections and analyzes that seek to understand its impact and influence today. In this sense, this article aims to delve deeper into the topic of Steam jet cooling, exploring its multiple facets and offering a broad and complete vision to delimit its scope and importance in the contemporary world.
Steam jet cooling uses a high-pressure jet of steam to cool water or other fluid media. Typical uses include industrial sites, where a suitable steam supply already exists for other purposes or, historically, for air conditioning on passenger trains which use steam for heating. Steam jet cooling experienced a wave of popularity during the early 1930s for air conditioning large buildings. Steam ejector refrigeration cycles were later supplanted by systems using mechanical compressors.[1]
Principle
Steam is passed through a vacuum ejector of high efficiency to exhaust a separate, closed vessel which forms part of a cooling water circuit. The partial vacuum in the vessel causes some of the water to evaporate, thus giving up heat through evaporative cooling. The chilled water is pumped through the circuit to air coolers, while the evaporated water from the ejector is recovered in separate condensers and returned to the cooling circuit.
Usage
The AT&SF railroad (Santa Fe) used this method, which they called "Steam Ejector Air Conditioning", on both heavyweight and lightweight passenger cars, built until the mid-1950s.
