The absorption refrigeration and absorption cooling are attractive when there is a source of inexpensive or waste heat readily available. This cycle uses a refrigerant that is readily soluble in a liquid transport medium. In brief, the condensation, expansion and evaporation processes are identical to those of conventional refrigerators and air conditioners. But instead of the latter's compression process, the absorption cycle's liquid transport medium absorbs the refrigerant vapor upon leaving the evaporator, creating a liquid solution. This solution is then pumped to a higher pressure, and then heat is used to separate the refrigerant from the solution, whereupon the high-pressure refrigerant flows to the condenser to continue the familiar cycle. The equipment used to accomplish the solution-dissolution processes is complex and heavy, but the advantage lies in the low work input requirement to raise the pressure of a liquid solution as compared to that required for compressing a gas. If the heat utilized is otherwise wasted heat, the low operating costs of absorption systems can be quite attractive. ...more on Wikipedia about "Absorption refrigeration"
Adiabatic demagnetization is a technique for attaining temperatures well below 1 kelvin. The fundamental principle was suggested by Debye (1926) and Giaque (1927), and the first working adiabatic demagnetization refrigerators (ADRs) were constructed by several groups beginning in 1933. Adiabatic demagnetization was the first method developed for cooling below ~0.3 kelvin (the temperature attainable by pumping on liquid 3He). ...more on Wikipedia about "Adiabatic demagnetization"
An air conditioner (often abbreviated to AC in the United States and Canada, and air-con in Australia and in Britain) is an appliance or mechanism designed to extract heat from an area using a refrigeration cycle. In construction, a complete system of heating, ventilation and air conditioning is referred to as HVAC. ...more on Wikipedia about "Air conditioning"
Aircooling (also: air cooling) is one method of dissipating heat. It works by making the object to be cooled have a larger surface area or have an increased flow of air over its surface, or both. An example of the former is to add fins to the surface of the object, either by making them integral or by attaching them tightly to the object's surface (to ensure efficient heat transfer). In the case of the latter it is done by using a fan blowing air into the object one wants to cool. In many cases the addition of fins adds to the total volume of material making a heatsink that makes for greater efficiency in cooling. ...more on Wikipedia about "Aircooling"

A Chiller is a machine that produces chilled water which is used to cool and dehumidify air in commercial and industrial facilities (see air conditioning). A typical chiller is rated between 15 to 1000 tons (180,000 to 12,000,000 BTU/h or 53 to 3,500 kW) in cooling power. There are basically four different types of chillers: Reciprocating, centrifugal, or screw-driven chillers are mechanical machines that can be powered by electric motors, steam, or gas turbines. Absorption chillers are powered by a heat source (such as steam) using no moving parts. ...more on Wikipedia about "Chiller"

A coolant, or heat transfer fluid, is a fluid which flows through a device in order to prevent its overheating, transferring the heat produced by the device to other devices that utilize or dissipate it. An ideal coolant has high thermal capacity, is low-cost, and is chemically inert, not causing nor promoting corrosion of the cooling system. Some applications also require the coolant to be an electrical insulator. ...more on Wikipedia about "Coolant"
A cooling pond is a man-made body of water primarily formed for the purpose of providing cooling water for a nearby power plant. Many such lakes have secondary outdoor recreational purposes that include fishing, swimming, boating, camping and picnicing. ...more on Wikipedia about "Cooling pond"
Cooling towers are structures for cooling water or other working medium to near-ambient temperature. The primary use of large, industrial cooling towers is to lower the temperature of the cooling water used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants and other industrial facilities. With respect to the heat transfer mechanism employed, the main types are: * wet cooling towers operate on the priciple of evaporation, (see Swamp cooler) ...more on Wikipedia about "Cooling tower"
This can be done passively by a heatsink which improves the thermal coupling between the CPU and the surrounding air. This may be combined with positive airflow through the computer case driven by the fans in the power supply, or for still higher power systems by actively cooling the heatsink with one or more integral fans circulating air through the heatsink (see aircooling). ...more on Wikipedia about "CPU cooling"

Deep lake water cooling uses cold water pumped from the bottom of a lake as a heat sink for climate control systems. Because heat pump efficiency improves as the heat sink gets colder, deep lake water cooling can reduce the electrical demands of large cooling systems where it is available. ...more on Wikipedia about "Deep lake water cooling"
A dilution refrigerator is a cryogenic device first proposed by Heinz London. Its refrigeration process uses a mixture of two isotopes of helium: helium-3 and helium-4. When cooled below 700 mK, the mixture undergoes spontaneous phase separation to form a 3He-rich phase and a 3He-poor phase. ...more on Wikipedia about "Dilution refrigerator"
The Einstein refrigerator is a type of refrigerator co-invented in 1926 by Albert Einstein and former student Leó Szilárd, who were awarded US patent number 1,781,541 on November 11, 1930. The machine is a single-pressure absorption refrigerator, similar in design to the gas absorption refrigerator. The refrigeration cycle uses ammonia (pressure-equalizing fluid), butane ( refrigerant), and water (absorbing fluid). The Einstein refrigerator is portable, made of inexpensive, nonmoving parts, operates silently, and is very reliable. However, leaks of the toxic ammonia caused problems among the earlier models. ...more on Wikipedia about "Einstein refrigerator"

Evaporative cooling is a system in which latent heat of evaporation is used to carry heat away from an object to cool it. The latent heat contains a considerable amount of energy, and carries away more heat than if the same temperature liquid was simply removed physically. ...more on Wikipedia about "Evaporative cooling"
A fan has two purposes – to move air for creature comfort or for ventilation and to move air or gas from one location to another for industrial purposes. Fans have broad surfaces that usually revolve. Leaves or flat objects, waved to produce a more comfortable atmosphere, are the simplest kind of fan. ...more on Wikipedia about "Fan (implement)"

A heat sink is an environment or object capable of absorbing heat from another object with which it is in thermal contact (either direct contact or radiational "contact"). In common use, it is a device made of metal brought into contact with the hot surface of a component (in most cases, some kind of thermal interface material is put between the heat sink and the heat source to increase thermal throughput), such as a microprocessor chip or other power handling semiconductor in order to stablise its temperature through increased thermal mass and heat dissipation (primarily by conduction and convection and to a lesser extent by radiation). Heat sinks are widely used in electronics, and have become almost essential to modern central processing units. ...more on Wikipedia about "Heat sink"
Heliox is a gas that is composed of a mixture of helium (He) and oxygen (O2). The term Heliox generally describes a mixture that is 21% O2 (the same as air) and 79% He, although other mixtures are available. Heliox has been used in a medical context since the 1930s, and although the medical community adopted its use initially to alleviate the symptoms of upper airway obstruction, its range of medical uses has since expanded greatly, most of which are dependent on the low density of heliox. ...more on Wikipedia about "Heliox"
(Icehouse (building)) Ice houses were buildings used to store ice throughout the year, prior to the invention of the refrigerator.

Laser cooling is a technique that uses light to cool atoms to a very low temperature. It was simultaneously proposed by Wineland and Dehmelt and by Haensch and Schawlow in 1975, and first demonstrated by Wineland and coworkers in 1978. One conceptually simple form of laser cooling is referred to as optical molasses, since the dissipative optical force resembles the viscous drag on a body moving through molasses. ...more on Wikipedia about "Laser cooling" The Ultimate shortopedia Machine.
