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 holidays. When summers are hot, they may also be used just to get cold groceries home from the store, such as keeping ice cream from melting in a sizzling 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esky
Esky is a brand of portable coolers, originally Australian, derived from the word "Eskimo". The term "esky" is also commonly used in Australia to Generic trademark, 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 brand name was purchased by American 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). The brand "Esky" was used from around 1945, for an Australian-made ice chest, a free-standing insulated cabinet with two compartments: the upper to carry a standard () block of ice, and the ...

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. 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 (temperature differences cause electromotive forces), the Peltier effect (thermocouples create temperature differences), and the Thomson effect (the Seebeck coefficient varies with temperature). The Seebeck and Peltier effects are different manifestations of the same physical proces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coleman Company
The Coleman Company, Inc. is an American brand of outdoor recreation products, especially camping gear, now owned by Newell Brands. The company's new headquarters are in Chicago, and it has facilities in Wichita, Kansas, and in Texas. There are approximately 4,000 employees. Some of the products manufactured are portable stoves, lanterns, coolers, sleeping bags, camp chairs, and shelters. History The company was founded by William Coffin Coleman, who began selling gasoline pressure lamps in 1901 in Wichita. In 1905, the company provided a demonstration for the 1905 Cooper vs. Fairmount football game (now Sterling College and Wichita State University). Coleman gas lamps were provided to play the first night football game west of the Mississippi River. In 1996, the company acquired the French Campingaz. In September 2004, Jarden acquired American Household, which was the privately-held parent company of Coleman as well as other brands like Sunbeam Products, for $745.6 mi ...

Temperature
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measurement, measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), with the third being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible ...

Freezing
Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. 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#Liquid–solid-phase transitions, hysteresis in its melting point and freezing point. It melts at and solidifies from . Crystallization Most liquids freeze by crystallization, formation of crystal, 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 removal of heat when in contact with air, which is a poor heat conductor. Because of the latent heat of fusion, the freezing is greatly slowed and the temperature will not drop anymore once the freezing starts but ...

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 (or use the service provided by the business) without leaving their cars. The format was pioneered in the United States in the 1930s, and has since spread to other countries. Drive-through facilities typically come in one of three forms. 1. Single lane, where the agent is in the kiosk on the driver's side; 2. Dual lane, with the left lane on the left side of the kiosk facing the right side of the vehicle, and the right lane on the right side of the kiosk, facing the left side of the vehicle, with either an agent for each lane or a single agent handling both lanes; and 3. multilane, with two or more lanes all with an agent on the driver's side of the vehicle. In some cases, a single lane kiosk may be approached in either direction at the driver's choice as to whether the driver or the passenger interacts wit ...

Fan (mechanical)
A fan is a powered machine that creates airflow. A fan consists of rotating 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 anemometers and win ...

Heat Pump
A heat pump is a device that uses electricity to transfer heat from a colder place to a warmer place. Specifically, the heat pump transfers thermal energy using a heat pump and refrigeration cycle, cooling the cool space and warming the warm space. In winter a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in summer. As they transfer heat rather than generating heat, they are more energy-efficient than heating by gas boiler. A gaseous refrigerant is compressed so its pressure and temperature rise. When operating as a heater in cold weather, the warmed gas flows to a heat exchanger in the indoor space where some of its thermal energy is transferred to that indoor space, causing the gas to condense into a liquid. The liquified refrigerant flows to a heat exchanger in the outdoor space where the pressure falls, the liquid evaporates and the temperature of the gas falls. It is no ...

Refrigerator
A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermal insulation, 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 preservation, food storage technique around the world. The low temperature reduces the reproduction rate of bacteria, so the refrigerator lowers the rate of Food spoilage, 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 freezer is a specialized refrigerator, or portion of a refrigerator, that maintains its contents’ temperature below the freezing point of water. The refrigerator replaced the icebox, which had been a common househ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
