20 Chilly Facts about Air Conditioning

Can you imagine a hot summer’s day without air-conditioning? Air conditioning is used to create and maintain a certain temperature, relative humidity, and air purity conditions in indoor spaces. One of the most refreshing feelings in the summer has to be entering into an air-conditioned space.

An air-conditioning system must be effective regardless of outside climatic conditions and involves control over four fundamental variables: air temperature, humidity, movement, and quality. We love it because it maintains a level of personal comfort, and who doesn’t want comfort? But is that all? Read these fun facts about air conditioning and you’ll be even more appreciative of these devices that make our life cooler…

4. Gorrie is credited as the AC master.

John Gorrie is considered the father of refrigeration and air conditioning. As a Floridian doctor in 1842, he developed a machine that made ice to cool the air for his patients. He was granted a patent to create a similar machine for homes and buildings but died before he could create it.
