This week we celebrate the 114th anniversary of “cool” just as a major heat wave settles over the United States and experts predict record warmth on a global basis for the year.
On July 17, 1902, Willis Carrier invented modern air conditioning to help solve a production problem at the Sackett & Wilhelms printing plant in Brooklyn, New York. Once Carrier identified the way to reduce the dew point and lower the temperature via his new “cooling machine,” the heat and humidity no longer wreaked havoc on the printer’s supply of paper and ink.
From that first installation, which effectively helped avoid waste and preserve resources, to today’s modern and energy-efficient systems, sustainability has consistently been a Carrier focus.
United Technologies is proud to be a part of this history, and even more proud to have worked throughout the years to create non-ozone depleting technology to ensure that we balance sustainability with efficiency and performance. Carrier was the first in the world to phase-out of ozone depleting CFC refrigerants and to begin using non-ozone depleting cooling technologies. Scientists recently confirmed the Earth’s ozone layer is well on its way to recovery thanks in part to the investments in non-ozone depleting technologies.
Today, Carrier pushes technology further by using recycled carbon dioxide (CO₂) as a refrigerant instead of high global warming synthetic refrigerants. In the case of Carrier’s NaturaLINE® marine container refrigeration system, the use of CO2 as a refrigerant reduces emissions by up to 28%, as compared with previous systems. We’ve been able to make significant advancements in the transport and stationary refrigeration industries that we serve today, which lead to improved management of the cold food supply chain around the globe.
To better understand the impact our efforts have had on the environment, we started tracking the metric tons of CO2 saved by our high efficiency products in 2000. We call it the Carrier CO2NSERVATION Meter and it recently hit a new milestone - 200 million metric tons of avoided CO2! That is equivalent to keeping nearly 37 million vehicles off the road each year.
