The refrigerator absorbs heat from the food and cools the food. As a result, germs or bacteria cannot grow in this cold environment. So the food stays good.
Who doesn’t want to eat fresh. And since this demand, the fridge is now a constant companion of people. Although this electronic device for cooling food is generally known as a fridge, the academic name is refrigerator. The main task is to keep food, drink and various life-saving medicines cool and good for a long time.
The advent of refrigerators has been through a lot of research and development. This research has been going on for more than 50 years. Scientists were then able to create simple and safe refrigerators. With the change in lifestyle, refrigerator seems to be one of the furniture in the house now.
From ancient times the people have always been looking for a way to cool down. In ancient Egypt, bottles were dipped in earthenware vessels to cool the drink and then covered with another earthenware vessel. Attempts to build refrigerators in modern times began in the 1900s. The need for the cold of that time and the picture was different! In Europe, icemen used to go from house to house to meet the cold. Now comes the morning hawker to give the magazine. Icemen used to come with huge chunks of ice. Pieces were bought from there and kept in a wooden box at home. There was another box under that box. The drink bottles were in the box below. Usually every two days the iceman would go through the ice. Refrigerators were pretty much like that in the early nineteenth century. This procedure lasts for several days. Due to the popularity of the method, the industry of cutting and selling ice deposited on the lake was also developed at that time. Even then, no one has adopted the method of artificially watering ice.
That's how it could go! But the problem is for the people of Australia. Due to the high temperature, natural ice could not be found there. It is also difficult to import ice from abroad. So they started looking for scientific solutions. The first solution was given by Jacob Perkins. However, the solution was seen with a crooked eye. Because if we go in a scientific way, the ice-cutting industry will be ruined and thousands of people involved in this industry will become unemployed. However, an Australian journalist named James Harris became interested in Parkinson's technology and built an artificial ice-making machine and took it to Australia. And thus began the journey of the modern refrigerator.
