Heating, ventilation, and air conditioning (HVAC) technologies have come a long way since ancient times. In fact, here’s a brief rundown of HVAC’s journey from 16th century laboratories to the modern home.
16th to 17th Centuries
In 1758, Benjamin Franklin and John Hadley’s work on the process of rapid evaporation gave way to future innovations in the HVAC industry, specifically cooling. As the pioneering researchers into various HVAC solutions, Franklin and Hadley closely conducted an experiment to explore how evaporation can be used to rapidly cool an object. They both confirmed that the evaporation of highly volatile liquids, such as alcohol and ether, can be used to drive down the temperature of an object beyond water’s freezing point. Aside from this, Franklin was also credited with the invention of the first stove, which was also regarded as the first steam-heating system in history.
18th Century to the Present
By the 1900s, one of HVAC’s most well-known figures emerged – Willis Haviland Carrier. As an engineer working at a Brooklyn printing plant, Carrier was tasked to find a way to significantly reduce the heat and humidity inside the plant as the latter is damaging the paper and colored ink being manufactured. Building on the concepts by those who came before him, Carrier invented the world’s first air conditioner – a device that can easily cool down a sweltering space. Carrier’s invention caught on and found its way into homes and commercial establishments; and the rest, they say, is history.
