Ancient Egyptian Air Conditioner over 4,000 Years Old
The air conditioning and heating systems appeared hundreds of years ago, but passed through different stages of modernization and improvement until today. Nowadays, people use completely automated and multifunctional AC and HVAC systems, which make their everyday routine more comfortable.
A GLIMPSE OF HISTORY
FIRST AC SYSTEM
Air conditioner is a device that regulates the air condition. A person feels comfortable in a very narrow temperature range, only a few degrees, and if the problem with the cold was solved relatively simply, then the problem with heat remained a real problem for a long time.
The Frenchman Jeanne Chabannes patented the term air conditioning in 1815. The industrial use of this patent happened by accident in 1902 in New York. American Willis Carrier created a device that maintains constant humidity in the printing house, but in addition to humidity, his brainchild began to give out cold as a by-product. The effect was amazing and a year later, a similar device was created in Cologne and cooled the air in the theater. History is tactfully silent about the technical characteristics of this air conditioner, its dimensions and the number of maintenance personnel.
Something more or less similar to the air conditioner appeared only in 1929. General Electric has created the great-grandfather of modern split systems, a room air conditioner consisting of an outdoor and indoor unit. It did not go into mass production because ammonia was used as a refrigerant, which has a very characteristic odor and is harmful to health.
In the 60s, Japan seized the palm from the United States and is still the leader in this field. In 1958, Daikin invents a heat pump that allows air conditioners to be operated all year round and “teaches” them not only to cool, but also to heat the air. Toshiba begins serial production of split systems in 1961.
Daikin’s counter move was the creation of multi-split systems in 1969, when one outdoor unit served several indoor units located in different rooms. Toshiba said the final word in this controversy with the development of an inverter split system – one of the most popular air conditioning systems today.
