AIR CONDITION DUCTING PANELS & INSULATION MATERIAL

It was in the year 1906 that a humidifying head was created for the purpose of humidifying and treating the air in cotton mills and this is how the world's first air conditioning unit was made. A decade later, automatic controls for air conditioning units were installed, and soon large factories, munitions plants, ships, and mansions installed some of the world's first air conditioners. By 1926, air conditioners started to become popular in offices and homes, and by the 1940's refrigerators were brought into use, changing dramatically the way people worked and lived.
