Water is not used in refrigerators. Why?
Water is not used in refrigerators because it evaporates too slowly. Ether, another refrigerant, is never used in domestic refrigerators since it is both poisonous and inflammable. However, it is sometimes used for industrial refrigeration because it evaporates very fast. Freon is usually used in domestic refrigerators as it evaporates fast, is non-toxic, and non-flammable.
