In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
A 3He/4He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK, with no moving parts in the low-temperature region. [ 1][ 2] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
Globally. A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [ 1] This induces polar molecules in the food to vibrate [ 2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and ...
Dacor (/ ˈ d eɪ k ɔːr / "day-core") is a subsidiary of Samsung Electronics America that designs, manufactures and distributes kitchen appliances, specializing in the high-premium product tier, including wall ovens, ranges, cooktops, dishwashers, warming drawers, microwaves, ventilation hoods, refrigerators and wine dispensers.

An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used. An absorption refrigerator uses two coolants: the first coolant ...
Globally. Food in a refrigerator with its door open. A refrigerator, commonly 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 ...
Magnetic refrigeration. Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field and becomes cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ...
The Samsung T9000 is a smart refrigerator that runs Android (operating system) made by Samsung Electronics and introduced along with a soda-making fridge [1] in CES 2013. It was succeeded by the Samsung Family Hub refrigerator line which runs Tizen. [2] In early 2014, Samsung released the Samsung Smart Home app and service, now called Samsung ...
