In almost 100% of the kitchens there is a refrigerator, and approximately 15 to 15 minutes you hear a motor turning, and it’s what keeps the refrigerated products without the fridge every day we would have to play out leftovers instead of saving for another meal for example.
The refrigerator is one of the greatest and most important inventions of modern life. And even then it’s the only way to preserve food in another way were salting and have cold drinks in the summer was a great luxury.
Here’s how a refrigerator works, and we will also see something about refrigerated containers, coolers electronics and also the propane refrigerators found in RVs.
A fundamental and important reason for having a refrigerator is keeping food cold enough. Low temperatures help keep food fresh for longer. The basic idea behind all the refrigeration is to slow down the activity of bacteria that exist and are active in all foods, causing them to take longer to spoil food.
A bacterium that will spoil the milk for two or three hours if it is left at room temperature in the kitchen, if he reduces this temperature should stay fresh for a week or two at low temperatures inside the refrigerator, slowing down the activity of bacteria. At this cool milk, you can still even stop completely the activities of bacteria and milk may also last much longer.
Refrigeration and freezing are two most common ways to preserve foods used today. The basic idea of the functioning of refrigerators is very simple, it uses the evaporation of a liquid to absorb heat, and you know that when water evaporates it absorbs heat, creating a sensation of cold, the liquid evaporates used in refrigerators at a temperature that is lower. This way he can create freezing temperatures inside the refrigerator. If you put them in contact with a fluid coolant in your skin will freeze while it evaporates.
