An Engineering Guide to Air Conditioners and HVAC Topics
The articles in this guide are designed to help students and enthusiasts who are encountering these works for the first time in a high school, college, or work setting. Whether you’re looking for a detailed analysis of a technology, an explanation of a working methodology, or study questions so that you can prepare well for a quiz or an upcoming test, this series will help you tremendously.
How it All Began
A heat extracting device that also dehumidifies a specific area is called an air conditioner. Dr. John Gorrie was the first person who thought of making a device that could cool rooms and bring down the temperature. In the 1830s, he invented a device that was used to cool hospital rooms, but it was more of an ice making machine than an air conditioner. The first machine came into being in 1902, when Willis Carrier, an American engineer invented an apparatus for “treating air.” Gradually living styles improved, and industrialization and technological advancements increased the environmental temperature as well, which increased the demand for air conditioning systems. Let us first delve into the evolution and development of air conditioners and HVAC technology.
