Ben Franklin Was Really Cool

Ben Franklin Was Really Cool

Benjamin Franklin, one of our nation’s Founding Fathers, also had a hand in developing air conditioning. It happened in 1758. Working alongside a chemistry professor from Cambridge University, Franklin set up an experiment based on the principle of evaporation. Could evaporating liquids be used to cool something? Like, say, the bulb of a mercury thermometer?

Yes, they could. While air conditioning repair in Evans, CO was still centuries in the future, Franklin and his partner decided to douse the bulb in extremely volatile liquids, like alcohol and ether. The two went to work, augmenting the evaporation effort with a bellows to hurry it up. They found that the evaporation of these liquids could drive the temperature of the bulb down past the freezing point of water. They brought it down to seven degrees Fahrenheit in a spot where the ambient temperature was 64 degrees Fahrenheit. That was cold.

In his notes recording the results of the two men’s experimentation, Franklin wrote that after they had brought the temperature of the bulb down past the freezing point of water (32 degrees Fahrenheit), a thin film of ice appeared on the surface of the bulb. The ice was about a quarter of an inch thick when they halted the experiment at seven degrees Fahrenheit. Franklin, with his usual deadpan humor, wrote that, “From this experiment one may see the possibility of freezing a man to death on a warm summer’s day.”

Fortunately, there have been a few advancements in air conditioning since then. And you’ll find that Evans Air Experts, a locally owned and operated air and heating service company for everyone within a 30-mile radius of Greeley and Loveland, offers the very latest in heating and cooling systems.
