Whirlpool Refrigerator - Keeping it Cool
Early refrigerators were called ice houses or ice boxes. Ice cut from nearby lakes and rivers was stored in these containers. The Chinese cut and stored ice around 1000 BC and 500 years after that Egyptians and Indians placed jars out overnight to cool or make ice. When ice wasn’t available or practical, people used cool cellars or even placed goods underwater sometimes. The Hebrews, Greeks, and Romans were known to use snow placed in storage pits to keep things cold. In the 17th century, various places in Europe, Saltpeter or Potassium Nitrate dissolved in water was found to create cooling conditions and this was used to create ice. The Europeans also collected ice in the winter, salted it and wrapped it in flannel after which they stored it underground for several months. William Cullen invented the first form of the artificial refrigerator in 1748 - Glasgow, Scotland. He showed how the rapid heating of liquid to a gas can result in cooling. This is the principle even behind refrigeration and it still applies today. Though Cullen himself never turned his theory into practise, many others were inspired to actualize his idea. Refrigerator units became more common at home during World War II. In the year 1930, Albert Einstein designed his own form of a refrigerator and named it “Einstein’s Refrigerator”, which required no moving parts or electricity. Though he sold the patent to Electrolux, it didn’t last long in commercial production. Interestingly, Einstein used the royalties that he received from the patent to fund the “Manhattan Project”, which brought about the development of the atomic bomb. During the 1970s and 80s, there were many discoveries that were made linking CFC-gases like Freon to the depletion of the ozone layer. Environmental concerns led to the ban of “Freon” - an aerosol propellant and refrigerant, consisting of one or more of a group of chlorofluorocarbons and related compounds. Since then, refrigerators started using variations of tetrafluoroethane as a refrigerant. In 1805, Oliver Evans, an American inventor, designed a refrigeration machine that used vapour instead of liquid and in 1820 Michael Faraday received a patent for using liquefied ammonia to create a cooling effect. Jacob Perkins who worked with Evans also received a patent for a vapor-compression cycle using liquid ammonia in 1835. He is often referred to as the “Father of the Refrigerator”. In 1947, an automatic spinner-type washer was sold by Sears under the “Kenmore” brand, and a year later, it was sold by the company under the “Whirlpool” brand. In the year 1950, the Nineteen Hundred Corporation was renamed as the Whirlpool Corporation.
The popularity of commercial refrigerators grew tremendously towards the end of the 19th century due to breweries. By the turn of this century, nearly all breweries had a refrigerator. Today, refrigerators have gone from being a luxury necessity in every household. The meatpacking industry followed suit and went with the first refrigerator introduced in 1900. The refrigerators
of today work similarly to the olden day refrigerators. Early refrigerators used liquids and gases that were flammable, toxic, and highly reactive.
Refrigerators keep our food safe and fresh but these happen only if they’re operating at a proper temperature. When refrigerators are not kept cold enough, harmful bacteria can grow rapidly within perishable food and contaminate the entire fridge. Another thing to keep in mind is that refrigerators should not be overly packed. Even though cramming the last vessel into the fridge may seem like a good idea, you might be in danger of blocking the cooling unit that will chill your food. There is also a danger of the fridge door not being shut properly. The air inside the fridge needs to circulate around the food for the food to stay fresh. All the new stock should always be kept behind the old stock. It is also important to keep a check on the expiry date of the food inside the fridge in order to prevent food wastage and also ensure that you don’t end up eating stale food. Open cans especially containing food such as fruit and tomatoes should never be stored in the refrigerator as this may lead to chemical contamination. You can put the food in a container that is suitable for chilling. It is important to cool leftovers as quickly as possible, ideally within two hours and always defrost leftovers completely either in the fridge or in the microwave. When defrosted, it is advised against reheating food more than once, because the more number of times you reheat the food, the higher the risk of food poisoning.
