Cooler
A cooler, portable ice chest, ice box, cool box, chilly bin (in New Zealand), or esky (Australia) is an insulated box used to keep food or drink cool. Ice cubes are most commonly placed in it to help the contents inside stay cool. Ice packs are sometimes used, as they either contain the melting water inside, or have a gel sealed inside that stays cold longer than plain ice (absorbing heat as it changes phase). Coolers are often taken on picnics, and on vacation or holiday. Where summers are hot, they may also be used just for getting cold groceries home from the store, such as keeping ice cream from melting in a hot automobile. Even without adding ice, this can be helpful, particularly if the trip home will be lengthy. Some coolers have built-in cupholders in the lid. They are usually made with interior and exterior shells of plastic, with a hard foam in between. They come in sizes from small personal ones to large family ones with wheels. Disposable ones are made solely f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Esky
Esky was an Australian brand of portable coolers. The term "esky" is also commonly used in Australia to generically refer to portable coolers or ice boxes and is part of the Australian vernacular, in place of words like "cooler" or "cooler box" and the New Zealand "chilly bin". The term derives from the word "Eskimo". Esky brand was purchased by United States firm Coleman Company, (a subsidiary of Newell Brands) in 2009. History Some historians have credited Malley's with the invention of the portable ice cooler. According to the company, the Esky was ''"recognised as the first official portable cooler in the world."'' The company's own figures claim that, by 1960, 500,000 Australian households owned one (in a country of approximately 3 million households at the time). Outdoor recreation company Coleman Australia bought the Esky brand from Nylex Ltd after the company went into administration in February 2009. Esky has been producing coolers since 1952. Coleman still produces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peltier Effect
The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa via a thermocouple. A thermoelectric device creates a voltage when there is a different temperature on each side. Conversely, when a voltage is applied to it, heat is transferred from one side to the other, creating a temperature difference. At the atomic scale, an applied temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side. This effect can be used to generate electricity, measure temperature or change the temperature of objects. Because the direction of heating and cooling is affected by the applied voltage, thermoelectric devices can be used as temperature controllers. The term "thermoelectric effect" encompasses three separately identified effects: the Seebeck effect, Peltier effect, and Thomson effect. The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Bag
A thermal bag is a type of thermally insulated shipping container in the form of a bag which can be carried, usually made of thermally insulating materials and sometimes a refrigerant gel. It is used to help maintain the temperature of its contents, keeping cold items cold, and hot items hot. Insulated bags have been in use for many years in industry, medical/pharmaceutical use, food delivery, lunch bags, etc. Several designs have been available. Shopping bags Commercial thermal shopping bags, to carry temperature-sensitive purchases home without breaking the cold chain, were first introduced by grocery and other shops in Europe in the mid 1980s. A thermal bag to keep pizzas being delivered hot was invented by Ingrid Kosar in 1983, and is commonly used now. A cool box is very similar in concept, but typically larger and in the form of a rigid box. Medical use Thermal pharmaceutical bags are designed to transport temperature-sensitive medications, protecting them from dam ...

Fan (mechanical)
A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an ''impeller'', ''rotor'', or ''runner''. Usually, it is contained within some form of housing, or case. This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines. Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air. Fans produce air flows with high volume and low pressure (although higher than ambient pressure), as opposed to compressors which produce high pressures at a comparatively low volume. A fan blade will often rotate when exposed to an air-fluid stream, and devices that take advantage of this, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drive-through
A drive-through or drive-thru (a sensational spelling of the word ''through''), is a type of take-out service provided by a business that allows customers to purchase products without leaving their cars. The format was pioneered in the United States in the 1930s, and has since spread to other countries. Hillcrest State Bank, Dallas, Texas, installed the first drive-through banking system in America. It was a George Dahl designed building, constructed in the 1920s, across from SMU. The second recorded use of a bank using a drive-up window teller was the Grand National Bank of St. Louis, Missouri in 1930. The drive-up teller allowed only deposits at that time. Orders are generally placed using a microphone and picked up in person at the window. A drive-through is different from a drive-in in several ways - the cars create a line and move in one direction in drive-throughs, and normally do not park, whereas drive-ins allow cars to park next to each other, the food is generally bro ...

Freezing
Freezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting point and freezing point. It melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F). Crystallization Most liquids freeze by crystallization, formation of crystalline solid from the uniform liquid. This is a first-order thermodynamic phase transition, which means that as long as solid and liquid coexist, the temperature of the whole system remains very nearly equal to the melting point due to the slow re ...

Refrigerator
A refrigerator, colloquially 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. Refrigeration is an essential food storage technique around the world. The lower temperature lowers the reproduction rate of bacteria, so the refrigerator reduces the rate of spoilage. A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is .Keep your fridge-freezer clean and ice-free ''BBC''. 30 April 2008 A similar device that maintains a temperature below the freezing point of water is called a freezer. The refrigerator replaced the icebox, which had been a common household appliance for almost a century and a half. The United States Food and Drug Administration recommends tha ...

Refrigerant
A refrigerant is a working fluid used in the heat pump and refrigeration cycle, refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated due to their toxicity, flammability and the contribution of CFC and HCFC refrigerants to ozone depletion and that of HFC refrigerants to climate change. Refrigerants are used in a Direct Expansion (DX) system to transfer energy from one environment to another, typically from inside a building to outside (or vice versa) commonly known as an "air conditioner" or "heat pump". Refrigerants can carry per kg 10 times more energy than water and 50 times more than air. Refrigerants are controlled substances due to 1) High Pressures (100-145 psi), 2) Extreme temperatures (-50°C to 145°C), 3) Flammability A1 class non-flammable, A2/A2L class flammable & A3 class extremely flammable/explosive and 4) Toxicity B1-low ...
