Introducing Refrigerators

The very first refrigerators, so to say, were built as ice houses. These buildings contained man-made underground chambers, which are built close to natural options for winter ice including freshwater lakes. During winter, this ice and snow can be packed into the ice house along with straw or sawdust that has been useful for insulation. The ice house kept the ice intact for several months on end, even through summer.

Many countries tell you he is the home of the refrigerator. Over time, refrigerator technologies have evolved in extreme measures. One of the first home refrigeration units was installed at Biltmore Estate in Vermont in around 1895. That very same year, the first commercial refrigeration unit was opened through the Vestey Brothers in London.

Present day refrigerators primarily work on electric power, however some in the older models use gas being a source of energy. Today, a domestic refrigerator exists in 99.5% of yankee homes. It functions using phase change heat pumps operating in a refrigeration cycle. A commercial refrigerator is just a refrigerator used in a commercial setting, usually in the restaurant or supermarket where large quatities of food stocks are stored. They may consist of either a cooling compartment (a more substantial refrigerator), a freezing compartment (a freezer) or both. The dual compartment was introduced commercially by General Electric in 1939. Some refrigerators are actually separated into four zones for that storage of various kinds of food at different temperatures.
