Air conditioner systems were mainly used in the ancient days to preserve food. These systems provided a low temperature (under 4°C or 40°F) to prevent harmful bacteria from spoiling the food. This system also offered several other benefits in terms of air conditioning, manufacturing processes and humidity control.

What was the principle behind refrigeration?

The principle of the refrigeration was introduced in the year 1824 by a renowned physician named “John Gorrie.” It showed that liquid form of ammonia could cool the air when it is made to evaporate. This created ice with the help of compressor technology.

When did commercial air conditioner come into existence?

Commercial air conditioning systems came into market in the year 1902. The need for their introduction was for industrial processes than personal convenience. The air cooling it provided helped in the successful accomplishment of several industrial processes. The 1st electrical air conditioning system was invented in the year 1902 by scientist Willis Haviland Carrier. Due to his marvelous invention, he began to be called as the “Father of Modern Air Conditioning.”

Air conditioning units were originated in the 2nd century in China, where a scientist named “Ding Huane” manufactured a manually operated rotary fan. In the year 2000, air refrigeration was listed among the ten greatest achievements in the field of mechanical engineering, of the 20th century.

In the year 1933, the carrier air conditioning firm of US developed an air conditioner with the help of a blower, belt-driven condenser, evaporator coil and mechanical controls. This model captured the thriving U.S. marketplace as soon as it was introduced.

In what ways did commercial air conditioning systems contribute?

The invention of commercial air conditioner systems improved the overall functioning of manufacturing procedure of a printing plant. The design of Llyod AC systems offers efficient controlling of the humidity and temperature of the plant. The processes got more efficient as the size of paper and the alignment of ink was consistently maintained. It leads to employee comfort and enhanced productivity.

Invention of refrigerant

The invention of a safer refrigerant “Freon” in the year 1928 made it more beneficial for residential, commercial, and industrial application. To comply with the standard set of regulations, AC manufacturers have increased the “Seasonal Energy Efficiency Ratio” to 16 / 18. This aids the environment and enables power cost savings for users.

Introduction of smart technologies

To further minimize energy usage, today’s AC manufacturers work on the same Carrier’s 1933 principle. They have started stretching their abilities of the standard wall-based thermostat by manufacturing sophisticated microprocessor-based control kits and diagnostic devices.

It helped in automating the execution of the air-flow and compressor system. Remote thermostat feature enables the homeowner to easily adjust settings and functions on the AC from any off-site PC and web-enabled phones.


In these brilliant ways, air conditioning systems have grown from just a luxury to a basic necessity in any household. With every invention, the quality of the life of its users and productivity of industrialized processes has enhanced.
