Refrigerators are important because they keep our food cold. Without them, we wouldn’t have ice-cream or smoothies, or even cold, juicy apples. You would have to go to the grocery store daily just for cold food. Without keeping your food cold, your food would rot. If you didn’t get rid of it and someone ate it, they would probably die from eating it. So refrigerators are an important part in society. They keep food cold and they help prevent some people from getting sick. They keep medicine cold, which is very important to many people.

The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.

Refrigerators may be large boxes but they’re far from monolithic. They come in a range of shapes, sizes, and designs. Each style has its specific strengths and weaknesses. Some fridge types generally cost less but won’t offer many fancy features. Others tend to have all the latest bells and whistles plus a massive price and large size. Buying the wrong style appliance could mean bad news. You might get stuck with a bloated bill, no frills at all, or something that won’t fit where you want it.

Talk about a life-changing invention. Refrigerators allow us to easily preserve food, as opposed to the old days, when this was a major chore. Now food that might spoil in a couple hours on the counter, will last a couple weeks in the fridge. This not only makes our lives more convenient but also helps us stay healthy by reducing the risk of food-borne diseases. Lowering the temperature slows down the growth of bacteria significantly. When something is frozen, bacteria growth stops entirely.

How do refrigerators work?

When you’re hot, you sweat. This liquid (sweat) then evaporates causing your body temperature to drop. This is basically the same thing that happens with a refrigerator, except that when the liquid evaporates, that vapor is trapped, and the cycle of vaporizing and returning to liquid continues.

If you look underneath or at the back of a refrigerator, there is a thin pipe running back and forth. At one time, the pipe was filled with Freon gas. This isn’t exactly environmentally friendly in the case of a leak, so a different type of gas or refrigerant is used today.

The refrigerant begins as a liquid and is pumped, by means of a motorized compressor, through tubes inside the fridge. This compresses the refrigerant and turns it into a vapor, pulling the warm air out of the fridge, leaving cold air in its wake. The vapor then passes through the thinner pipes outside the fridge, warming up, and turning to a liquid again. Warm air is released into the room, so you’ll often feel heat coming from behind or beneath the fridge. The whole cycle is then continuously repeated.

When the fridge reaches the desired cold temperature, the compressor shuts off. When the fridge warms up again, because it’s not completely air-tight, or because you’ve been standing with the door open staring at the stuff in the fridge, deciding what to eat, you’ll hear the compressor come back on. We’re all familiar with the sound of the fridge “kicking in”.

Refrigeration and freezing are two of the most common forms of food preservation used today and listed below are some of the best refrigerators that you can find currently on Amazon.
