The original concept of air conditioning is thought to come from Ancient Rome. Also, it’s said that early cooling applications and techniques were used in Medieval Persia using cisterns and wind towers. The emergence of central air conditioning came forth in the early 19th century due to the advances in chemistry.

All refrigerators and air conditioners work on the evaporation and condensation cycle. As the coolant evaporates, it takes in heat, and moves it outside when it condenses. On a gas-powered air conditioner or refrigerator, the evaporation is done by a gas burner.
