I am very happy to learn about the history of mini-splitting from someone who has actually lived.

Before my current position in Tosot Bathica, Quebec, I did some contract work for Heat Controller, Inc. in Jackson, Michigan. You may know them by the brand name Comfort-Aire.

I was fortunate to learn about the history of mini split from a person who had experienced it firsthand. Mr. Don Peck was the CEO of Heat Controller at the time and worked there for more than 50 years.

Don always proudly tells me that FIRST mini split is developed by Heat Controller. The following are his original words:

"The Comfort-Aire Twin was first introduced in 1965. It is a window air conditioner with a split cabinet design. The window can be close to the center of the unit, while the compressor and condenser fan are located outside the window. The fan makes the application very quiet."

This is the actual documentation of Comfort-Aire Twin Pac. Look at the indoor unit... It seems that everything is the wood grain of the 70s!

Twin Pac is the first mini split type, a branch of Twin. It was originally developed for Sears in 1969 under the name "Sears Modular Central Air Conditioning System". The device is available in two sizes, 6000 (115 V) and 16000 (230 V). The original unit was only 8 feet. Refrigerant line and quick connection, and includes a double wrench kit for connection.

In 1971, Twin Pac went on the market under the Comfort-Aire label. Then three sizes (6000, 11000 and 16000) are provided. The cord set accessories have also been changed to allow distances of up to 19 feet between indoor and outdoor installations. When the federal government established the first energy efficiency ratio (EER) rating of 8.0 in the late 1980s, the product disappeared because it was classified as a split system rather than a room unit.

Tang always pointed out that in 1974, the Comfort-Aire Twin Pac won the Michigan Product of the Year Award. It defeated the 1974 Ford Mustang.

Now, you might say that almost anything should beat this car, but those of us who are old enough to remember know that Ford sold a bunch of these cars, and any non-auto product winning in Michigan is unheard of. . time.

Now, let's enter the DeLorean DMC-12 in 1982 and set the flux capacitor to 2021...52 years after the first mini split in North America was launched.

In these 52 years, we went from the lunar module to the space shuttle to Space-X.

We started with the 1969 Ford Mustang Mach 1 with 390 cubic inches. The 6.4-liter V8 engine, the Mustang II equipped with a 2.3-liter 4-cylinder engine in 1974, and the 2021 Mustang Shelby GT500 equipped with a 760-horsepower supercharged 5.2-liter V8 engine.

We went from Comfort-Aire Twin Pac with EER less than 8 in 1969 to modern mini-split devices. For example, Tosot Lomo Plus has an EER of 15.3 and a seasonal energy efficiency rating (SEER) of 30.5 (9K Lomo Plus has an EER of 16.5 and SEER of 38. ).

Oh, yes, the maximum cable length of the Comfort-Aire Twin Pac is 19 feet, and the maximum cable length of modern units is 164 feet. This is progress.
