When was air conditioning invented?

July 1902 Carrier, a young man who just graduated from Cornell University for one year, invented air conditioning while working in Buffalo Company. But the original purpose of air conditioning was not to bring people a comfortable living environment, but to serve some dead things.

The invention of air conditioning is called the father of refrigeration. The British inventor Willis haviland Carrier designed and installed the first air conditioning system in 1902. The air conditioning system was designed for a printer in new york, USA. He found that the change of temperature would cause the deformation of paper, which would lead to the imbalance of color ink. Carrier registered the patent 1906.

principle of operation

Air conditioning is divided into single cooling air conditioning and cold and warm air conditioning, and the working principle is the same. Freon used to be the common refrigerant in air conditioning. The characteristic of freon is that it releases a lot of heat when it changes from gas to liquid. When it changes from liquid to gas, it will absorb a lot of heat. That is, the air conditioner is designed according to this principle.

The compressor compresses the gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant, and then sends it to the condenser (outdoor unit) for heat dissipation, and turns it into liquid refrigerant at normal temperature and high pressure, so the outdoor unit blows out hot air.
