The history of refrigeration

The history of refrigeration

Refrigeration is the action of creating cooling conditions by removing heat. It is used for preserving food by slowing bacteria growth.

  • Around 1000BC, the Chinese used to cut and store ice.
  • Five hundred years later, the Egyptians and Indians left earthenware pots out during cold nights to make ice.
  • In the 17th century, it was found that saltpeter dissolved in water creates cooling conditions.
  • In the 18th century, Europeans collected ice in winter, salted it, wrapped it in flannel, and stored it underground for months. Ice was even shipped around the world.
  • People also used cool cellars or placed goods underwater.
  • Others built ice boxes out of wood, lined with tin or zinc, and insulated with cork, sawdust, or seaweed, and filled with snow or ice.
