Know about Insulated Icebox Industry

A cool box (also called a refrigerator) is a compact, non-mechanical refrigerator that was a common kitchen appliance in the early 20th century before the development of safely operated refrigerators. Before electric refrigerators were developed, cool boxes were referred to as "refrigerators" by the public. It was only after the invention of the modern electric refrigerator that the early non-electric refrigerators became known as cool boxes. The terms ice box and refrigerator were used synonymously in advertising as early as 1848.

The first proven use of refrigeration technology dates back to 1775 BC. In the Sumerian city of Terqa. It was there that the king of the region, Zimri-lim, began building an ornate ice house that was equipped with a sophisticated drainage system and shallow pools to freeze water at night. Using ice for chilling and preserving was nothing new at the time, but these ice houses paved the way for their smaller counterpart, the cool box. The more traditional cool box dates from the ice harvest period, which had reached an industrial peak from the mid-19th century to the 1930s when the refrigerator was introduced into the home.

Most of the ice consumed communally was harvested in winter in snow-covered areas or frozen lakes, stored in ice houses and shipped domestically. In 1827, the commercial ice cutter was invented which increased the ease and efficiency of harvesting natural ice. This invention made ice cream cheaper and, in turn, helped make the ice box more common. Up until that point, cool boxes were used for personal purposes but not for mass production.
