The indoor environment of any building or closed space needs ventilation so that the indoor environment is comfortable. The temperature of the room must be warm if the outside temperature is cool and vice versa. The system that helps maintain the temperature and air purification are HVAC, where H stands for heating, V stands for ventilating, and AC stands for air conditioning. The elements of the HVAC systems, such as filters, ducts, compressors, air conditioners, ventilators, electrical devices, etc., were developed over time and have now resulted in the best technological HVAC system.

The Evolution of the HVAC system
The heating and cooling system was discovered thousands of years ago. To keep the environment cool, the Egyptians hung wet reeds in the windows, causing the air passing through them to cool. Also, the ancient cultures of the east involved building wind catchers: long chimneys that acted as the direction for the winds to enter the building. In the Iron Age, people used a furnace, buried pipes, and stones to produce heat and raise the temperature.
During the industrial revolution in 1800, cast iron radiators came into being. These radiators were widely used to heat the rooms with energy from steam or hot water. Oliver Evans invented the refrigeration machine in 1805. The cooling technology encountered another breakthrough in the 1840s when a doctor invented the first powered ice machine. The reason for the invention was the increased symptoms of the patient due to the heat in Florida.
In 1902, the first air conditioner (AC) was invented, which removed excess moisture from the air. In 1904, a new 35,000 cubic foot air conditioner was circulated inside Missouri’s state building.
The inventions did not stop; more and more innovations were seen in the 20th century. These inventions resulted in the development of the HVAC system, which is now in great demand. The heating, ventilating, and air conditioning systems have a rich history of innovations and are going to evolve in the future due to technological advancements.
