A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...
Food in a refrigerator with its door open. A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature.

The start of the Kimchi refrigerator dates back to 1984. At that time, LG predecessor, GoldStar (금성사), first used the word 'Kimchi refrigerator' (김치 냉장고). The model name of the first kimchi refrigerator was 'GR-063', and according to the advertisement], the inside was made of stainless steel and the internal temperature could be ...
While this technique was originally applied to the refrigerator compartment, it was later used for freezer compartment as well. A combined refrigerator/freezer which applies self-defrosting to the refrigerator compartment only is usually called "partial frost free" or semi-automatic defrost (some brands call these "Auto Defrost" while Frigidaire referred to their semi-automatic models as ...

LG Smart Refrigerator at CES 2011. A smart refrigerator is a refrigerator that is able to communicate with the internet. [1] This kind of refrigerator is often designed to automatically determine when particular food items need to be replenished.
Copper, steel, brass, iron, and nickel are commonly used metals in bimetallic strips. [6] Metal alloys have been used in bimetallic strips as well, such as invar and constantan . Material selection has a significant impact on the working temperature range of a bimetallic strip, with some having a temperature limit up to 500°C, with others only ...
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
