Quick Summary

A snow cellar, also known as a root cellar, is a room built underground or partially underground. It is designed to store fruits and vegetables by maintaining a constant temperature and humidity, protecting them from freezing.1

Historically, before mechanical refrigeration, people used snow cellars to store ice transported from mountains. These pits were insulated with wood and straw, allowing ice to be preserved for months.2

Refrigeration itself is the process of removing heat from an enclosed space to lower its temperature. This is primarily used today to preserve foodstuffs by inhibiting the growth of bacteria, yeast, and mold.2
