The ice box. An insulated chamber cooled by a block of ice harvested from lakes and streams and delivered to your home by the ice man. Before ice boxes farmers had a spring house where cold spring water flowed through a tub, keeping some items (butter, eggs) cool. Others had root cellars, just a big hole in the ground sometime they packed ice in saw dust to keep it cool in the warmer months. If they had a cave on their property it wasn't unusual for that to be used for cold storage, even to the point of keeping ice collected in the winter for summer use.
Refrigerators are used in houses
The refrigerant typically used in refrigerators is called R-134a.
The type of freon typically used in refrigerators is R-134a.
The most common refrigerant used in refrigerators is R-134a.
refrigerators
The refrigerant commonly used in new refrigerators is R600a, also known as isobutane.
Helium is not typically used in refrigerators for cooling purposes. Refrigerators commonly use refrigerants like fluorocarbons, hydrocarbons, or ammonia to facilitate the cooling process. Helium is often used in cryogenic applications or for leak detection.
Refrigerators are not bulletproof, but they are built heavy and can take a few heavy knocks and hits before breaking.
The most common refrigerant used in household refrigerators is R-134a.

No, freon is no longer used in refrigerators today. It has been phased out due to its harmful effects on the environment, and refrigerators now use more environmentally friendly refrigerants.
The gas commonly used in refrigerators is called refrigerant, with some of the most common types being chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). These gases help in the heat transfer process that allows refrigerators to cool and maintain low temperatures inside.
