It was in 18th century that the process of invention of refrigerator started. In 1748 William Cullen of University of Glasgow developed a process for creating an artificial cooling medium. No one took interest in it for commercial or home consumption, it only attracted scientific attention. An American inventor Oliver Evans made the first design for the refrigerator in 1804 but until 1834 none was interested in the same. Jacob Perkins built the first refrigeration machine in 1834. In 1844, a physician John Gorrie built a working unit on the basis of Oliver’s designs. He constructed this unit to create cooling atmosphere for his patients who were suffering from yellow fever.
In 1876 Carl von Linden invented the improved method of liquefying gas and got it patented. This was a great help in the creation of practical refrigerator. Ammonia, sulphur dioxide and methyl chloride were utilized for the formation of this gas which led to many accidents. The need led to the development of Freon and was used in bulk till it was found that it was not environment friendly and affected the ozone layer.
The gas compounds have now changed to safer compounds which compress and heat up working to cool the inside air of the refrigerator. Without this adjustment the working of the refrigerator seems impossible. It has been a work of many great inventors that the present form of refrigerators has simplified the work.
That really help me on my homework assignment
Keep up the good work
thank You
this helped me a lot on my homework
hmmm i guess it was good it did kinda help especial this part “It was in 18th century that the process of invention of refrigerator started.

Add more in4mation I want to know more!
This helped me alot on my homework assignment thank you.
This maybe sounds crazy, but Iam eager to know if anyone who does cooling equipment or appliances can make a wrist band or necktie that will give a person wearing it , will lower their body temperature. Heat is unbearable in a country with only two season like here in the Philippines. .
😜
We’re where they made
