Before the age of the fridge, leftovers during the summer usually meant a waste of money and food, no matter how much was left over. After the fridge was invented, people who could afford such a device knew they were given a blessing that would not only save their money, but also cause them less stress- or at least they thought so. Does the fridge really give us all that we believe it provides? Or is the fridge just an illusion reflecting what we consider to be our standard of living?
Back in the day, food could only be preserved during the chilly winters of December or in underground rooms that maintained its cool temperature throughout the seasons. During the summer, people would label cards with how much ice they wanted. Then icemen would come (in a wagon or chilled box), and fill up an icebox with the amount of ice demanded before moving on the next house. Using these techniques did not prove very effect, because chilly weather conditions were spontaneous, and ice would last only a short time before turning into water. So when the fridge went on sale to the public, people were astounded at how much longer food could last with this new contraption. They wondered about the compartments and mysteries that functioned inside that magical big white box.
The basic idea behind a fridge is that the cold temperatures slow down bacteria activity (something that all food contains), so that the process of decaying food would take longer. The fridge contains and stores many different items, allowing their users to store – as well as preserve- anything they wanted for extended amounts of time. Inside the fridge lies a freezing chamber, a refrigeration chamber, a cooling system, a cooling circuit, and a cooling surface in each of the chambers. With this construction, temperature regulation is done by balancing the surfaces of each of the cooling units. Exterior units are made using glass, plastic, and metal. Using
