10 interesting facts you may not know about air conditioning

Did you know that the United States uses more electricity to power its air conditioners each year than the entire continent of Africa? There are many interesting facts about air conditioning that you may not know, so we have compiled a list of the top 10 facts to help you expand and improve your knowledge about air conditioning!

1. In the old days, before air conditioning was invented, homes and buildings were built with high ceilings, open walkways, porches, and landscaping for shade, among other features that kept residents cool. However, as air conditioning became more common and standard, architects stopped designing buildings for cooling (making it much harder for us to do without it).

2. Before air conditioning was invented, schools and businesses would slow down or take summer breaks to avoid working in the sun. To this day, even after air conditioning became popular, schools continue to give students summer breaks as a rule.

3. Air conditioning helps alleviate allergies. Air conditioning has been shown to help people with asthma breathe easier. What is the reason for this? Air conditioners can remove allergens and other small particles from indoor air, leading to fewer sneezes and a more comfortable environment.

4. Willis Carrier invented the first air conditioner in 1902 to control humidity in a New York publishing house, not for cooling. He created it to prevent paper from expanding and shrinking, as well as to ensure that ink dried quickly and did not smudge.

5. The first home air conditioner was 7 feet tall, 6 feet wide, and 24 feet long, and was installed in 1914. People were willing to pay between $10,000 and $50,000 for one, despite its size. That would be between $120,000 and $600,000 in today's money! Residential air conditioning was only available to the very rich at the time.

6. The first air conditioner was an ice cube. People used to keep things cool and comfortable with large blocks of ice before air conditioning was invented. In fact, the efficiency ratings of the first air conditioners were based on the amount of ice needed to achieve the same cooling capacity.

7. In 1931, the first room-sized air conditioner was invented by HH Schultz and JQ Sherman. It was placed on a window ledge similar to today’s modern residential air conditioners.

8. The use of CFC and HCFC refrigerants severely damaged the ozone layer in the atmosphere, allowing harmful rays to penetrate straight to our planet. As a replacement, newer ozone-safe refrigerants such as R-11, R-12, and R-22 were created. In newer, more modern air conditioning systems, non-ozone depleting refrigerants such as R-410A and R32 are used.

9. In 1939, Packard introduced the first automobile with air conditioning. It was not very efficient due to its high cost and the fact that the evaporator and fan system took up half the trunk space.

10. The term “Summer Blockbuster” was coined because of air conditioning systems. Movie theaters were one of the first to adopt air conditioning technology in the early 20th century. People tended to flock to movie theaters in the 1930s not only to enjoy movies but also to enjoy the cool air during the summer months. Marketers took advantage of this and delayed the release of their films until the summer. As a result, the term “Summer Blockbuster” entered the dictionary.
