Initially, the main purpose of refrigeration was to conserve foods. The Chinese were the first to find out that ice increased the life and improved the taste of drinks and for centuries Eskimos have conserved food by freezing it. At the beginning of the 19th century, it had been observed that the growth of microorganisms is temperature dependent, that growth declines as temperature falls and that growth becomes very slow at temperatures below +10°C. As a consequence of this knowledge, it was now possible to use refrigeration to conserve foodstuffs and natural ice came into use for this purpose.
The idea of air conditioning started before a machine was created to produce the cooling effect desired. The first attempt at building an air conditioner was made by John Gorrie (1803−1855), an American physician, in Apalachicola, Florida. During his practice there in the 1830s, Gorrie created an ice-making machine that essentially blew air over a bucket of ice for cooling hospital rooms of patients suffering from malaria and yellow fever
