The Development of Refrigerators

by : teahupoo

For almost a hundred years now, no home has been complete without a freezer refrigerator. They first became widely available in the 1920's. The fridge, as its affectionately known, has become as necessary in today's home as the toilet or the walls and roof, for that matter. There are many types of freezer refrigerators. If you're old enough to remember them, or have come across one in an antique shop or junk yard, freezer refrigerators used to be made with the freezer built inside the refrigerated compartment. You had to open the fridge to get to the freezer. Modern freezer refrigerators can basically be broken down into three categories: side-by-side models, top freezer refrigerators, and bottom freezer refrigerators.

Side-by-side refrigerators are pretty popular, but they're not all that convenient for someone who stores a lot of food in their freezer. If you have such a refrigerator and plan on doing a lot of freezing, then you're probably going to have to invest in a chest-style reach-in freezer. The narrow door on such refrigerators can make accessing your food somewhat difficult.

Top freezer refrigerators may be the most common style of fridge. These, of course, have the main refrigerator compartment on the bottom and the freezer on top. Unless you're really short, the food is kept at a convenient height. The wide door makes accessing your food relatively easy. The wide-open freezer area can store a fair amount of food and not restrict you to a bunch of narrow shelves.

Bottom freezer refrigerators place the freezer beneath the refrigerated compartment. Of all the designs, the bottom freezer refrigerator makes the most sense. Warm air is less dense than cold air so heat rises and cold sinks. Given this truism, don't you think it'd make the most sense to put the coldest part of a freezer refrigerator on the bottom and the warmer part on top? Well, to many of us this does, indeed, make the most sense, and that's why the bottom freezer refrigerator has become increasingly popular in recent years. Because of this basic law of physics, bottom freezer refrigerators are the most efficient refrigerator design. Such efficiency means more money in your pocket because your electric bills will go down. Plus, these days we need to be more concerned with energy conservation as it pertains not just to your wallet, but to the environment as well. The less energy we use, the less fossil fuels we consume, and the less greenhouse gases we emit into our fragile atmosphere.

Freezer refrigerators come in a myriad of shapes, sizes, and styles. They can range in price from cheap mini-fridges to exorbitantly priced luxury models found the homes of the rich and famous. For the money, the best design is the bottom freezer refrigerator. It takes advantage of the laws of nature to more effectively freeze your food and keep it frozen.
