Refrigerators

It may seems confusing that liquid propane (LP) fuel used for heating can also be used to keep items cold. Though counter-intuitive, this process is commonly used for refrigerators installed in...

Portable refrigerators are devices used to keep drinks, food and other temperature-sensitive materials cool on the go. They can range in complexity from simple ice chests to more complex...

Refrigeration is an essential part of every day life for people. We need our cars cooled and our food stored in cold environments for freshness. You may have heard about some of the benefits of...

Defrost freezer with a heat gun!? Yes, you can. This is a quick and easy way to defrost the freezer, without needing to unplug the whole refrigerator or take a whole day to get the job done.

Refrigerators use the laws of heat transfer to keep certain compartments cold, channeling heat away from the air and into a gas that is pumped through the inner workings of the refrigerator. The...

Nearly all refrigerators, whether commercial, industrial or domestic are powered by a heat pump. Heat pumps are devices that pump a fluid through a circuit to transfer heat from one place to...

Freezer seals are essential to the proper operation of a freezer. Without a proper seal, a freezer is less efficient. Air leaking into the freezer carries moisture that causes rapid ice buildup,...

Thermoelectric coolers work based on a phenomenon called the Peltier effect. When two different metals are attached together and a current is run between them, heat is drawn out of one metal into...

A thermal insulator is any material that slows the transfer of heat. This means that the insulator reflects heat and does not emit much heat. Common insulators use vacant space as their...

A refrigerator is powered by a heat pump, a device that moves heat from one area to another. Cool is simply the absence of heat and can't be "made" by a refrigerator. As a matter of fact,...

A refrigerator seems like it should be fairly complex, but in reality it is much easier to understand than you would think. Your microwave oven is more complex than your refrigerator. Find out...

Refrigerators that use ignition are called absorption refrigerators. They are not the most common type. Most refrigerators use an electronic pump to circulate the coolant and cool food. These...

On the surface, the most puzzling thing about a refrigerator is the fact that the little light is on when you open it and off when you close it. The mechanics behind a refrigerator are actually...
