Saturday Jan. 2, 2021’s Smile of the Day: Air Conditioning

On this Day:

Willis Haviland Carrier received the first patent for the world’s first air conditioner.
Willia Haviland Carrier (November 26, 1876 – October 7, 1950) was an American engineer, best known for inventing modern air conditioning in 1902. In 1915, he founded Carrier Corporation, a company specializing in the manufacture and distribution of heating, ventilation, and air conditioning (HVAC) systems.

In Buffalo, New York, on July 17, 1902, in response to an air quality problem experienced at the Sackett-Wilhelms Lithographing & Publishing Company of Brooklyn, Willis Carrier submitted drawings for what became recognized as the world’s first modern air conditioning system. The 1902 installation marked the birth of air conditioning because of the addition of humidity control, which led to the recognition by authorities in the field that A/C must perform four basic functions:

• control temperature
• control humidity
• control air circulation and ventilation
• cleanse the air

After several more years of refinement and field testing, on January 2, 1906, Carrier was granted U.S. Patent 808,897 for an Apparatus for Treating Air, the world’s first spray-type air conditioning equipment. It was designed to humidify or dehumidify air, heating water for the first function and cooling it for the second.

In 1906 Carrier discovered that “constant dew-point depression provided practically constant relative humidity,” which later became known among air conditioning engineers as the “law of constant dew-point depression.” On this discovery he based the design of an automatic control system, for which he filed a patent claim on May 17, 1907. U.S. Patent 1,085,971 was issued on February 3, 1914.

On December 3, 1911, Carrier presented what is perhaps the most significant document ever prepared on air conditioning – Rational Psychrometric Formulae – at the annual meeting of the American Society of Mechanical Engineers. It became known as the “Magna Carta of Psychrometrics.” This document tied together the concepts of relative humidity, absolute humidity, and dew-point temperature, thus making it possible to design air-conditioning systems to precisely fit the requirements at hand (per Wikipedia).

First, a Story:

A friend of mine graduated from an air conditioning course.  He now has ‘A license to chill’…..

Second, a Song:

Paul Eason is a talented up and coming singer/songwriter with roots deep in the lone star state. This is Paul’s passion and it can be heard in magnitudes through the lyrics he lays on paper and the music he plays on stage. Paul’s songs have that feel good, love life appeal that has put Texas country on the map. At the same time, Paul maintains a style of music that fits a more pure country sound that the general audience outside of the Texas country fan base can love and appreciate.

Paul first started playing the guitar in 1995 and quite literally has not put it down since. But his love for music did not stop there – while a senior at the Houston High School for Performing and Visual Arts, Paul put together a group of talented professional musicians to form the Paul Eason Band. Since that time Paul has played alongside Texas and Country artists such as Roger Creager, Jack Ingram, Django Walker, Randy Rodgers, Radney Foster, Clay Blaker, Rick Trevino, the Great Divide, Davin James, and members of the Ace in the Hole band, the Pat Green Band, Gary P. Nunn’s Bunkhouse Band, the list goes on… the Paul Eason Band has played all across Texas, with no intent to slow down.

Born in Houston and now living in the Texas hill country town of San Marcos, Paul is steadily becoming a popular singer/songwriter. He is all about producing good music that makes people dance, sing, and enjoy life. With the new addition to his band of Texas steel guitar legend Danny Hawk – formerly of the Cory Morrow and Gary P. Nunn bands – along with the release of his first full length album, Paul and the band are making strides in the country music industry.

With a talented band, enthusiastic management, ever-growing fan base, and a little bit of luck behind him, Paul is ready to have some fun and make the country music scene a little bit better. The band has been busy touring to promote their debut album titled “Keepin’ it ‘Tween the Lines” as well as continue to captivate crowds that appreciate good Texas music (per

Here is Paul Eason performing “Air Conditioning”.  I hope you enjoy it!


Thought for the Day:

“It was luxuries like air conditioning that brought down the Roman Empire. With air conditioning their windows were shut, they couldn’t hear the barbarians coming.” – Garrison Keillor

Have a great day!
