Advantages:
Little environmental risk, very useful, less evidence.
Disadvantages:
It has more complex systems, danger of high temperatures, among others... -
Period: to
The modern cooling system
From the findings of William Cullen was devised how to use low temperature artificial environments for food preservation. Later, the original versions of modern refrigerators were developed.
Pros:
Increased food preservation.
Cons:
None
