I like it cool


Personally, I like to see fridges full of beer. So do the guys at BeerLoverCam, where you can upload your beer fridge photo.

The first domestic refrigerator was apparently manufactured in 1913 by Fred W. Wolf Jnr. in Chicago, and called the DOMELRE (DOMestic ELectric REfrigerator). It was not commercially successful, that distinction apparently going to the Kelvinator Company. This company was formed in May 1916 as the Electro-Automatic Refrigerating Company by Edmund J. Copeland and an industrialist, Arnold H. Gross. The company was renamed within two months to the Kelvinator Company and produced their first model shortly afterwards. Like most of their modern descendents, this refrigerator cooled using a phase change heat pump.

The first refrigerators were of the "remote" type, essentially an upgrade of an existing ice box with the installation of a cooling unit in it, but the motor, compressor and condenser installed either beside it or in the basement. The first self-contained refrigerators were not manufactured until 1925.

The earliest units used a toxic gas, sulphur dioxide as their refrigerant, converting it between gas and liquid through mechanical compression. It was not until the 1930s that General Motors developed the freons which were neither toxic nor inflammable and continued to be used until the 1990s.
