	Wikinfo \| Refrigeration (Site not responding. Last check: 2007-11-03)
		Refrigeration (from the Latin frigus, frost) is generally the cooling of a body by the transfer of a portion of its heat away from it.
		The refrigerator was invented in 1876 by Karl von Linde.
		The gas absorption refrigerator, which cools by the use of a source of heat, was invented in Sweden by Baltzar von Platen in 1922.

	Thermoacoustic refrigeration - Wikipedia, the free encyclopedia
		Sonic or thermoacoustic refrigeration is a technology that uses high-amplitude sound waves in a pressurised gas to pump heat from one place to another.
		This type of refrigerator has no ozone-depleting or toxic coolant and has few moving parts.
		A device consisting of a series of small parallel channels, referred to as a ‘stack’, is fixed in place at a set location inside the tube.

	Refrigeration (Site not responding. Last check: 2007-11-03)
		In some cases, refrigeration by material at ambient temperature is acceptable, for example the fan cooling of computer equipment.
		The function of a refrigerating machine, therefore, is to take in heat at a low temperature and reject it at a higher one, using external energy to drive the process.
		The gas absorption refrigerator[?] which cools by the use of a source of heat was invented in Sweden by Baltzar von Platen in 1922[1] (http://otal.umd.edu/~vg/amst205.F97/vj09/project5.html).

	Charging Residential Air Conditioning
		The process of a refrigerant changing its state (from a liquid to a vapor) in the metering device is called flash gas.
		Refrigerant saturation temperature is the pressure-temperature when the refrigerant is turning from a high-pressure vapor into a high-pressure liquid (giving up heat).
		Refrigerant saturation temperature is the pressure-temperature when the refrigerant is turning from a low-pressure liquid to a low-pressure vapor (absorbing heat).

	Rungis, les meilleurs produits au service du savoir-faire
		Accordingly, refrigeration technologies are being continuously developed to adjust to new regulatory requirements in terms of environment and consumption.
		Indirect refrigeration systems operate with a secondary fluid (refrigerating or cooling) that transmits the cold produced by a generator.
		Many studies are being carried out on these refrigerating fluids, among which the "ice slurry" (diphasic refrigerator – liquid/solid) is one of the most promising.

	Sonic Air Systems
		A Sonic 10 Hp blower system will generally do the work of 40+ Hp of compressed air in the same application.
		Low velocity fans are not powerful enough to break the boundary layer of surface heat and, in many cases, must be supplemented with refrigeration to make up for the lack of air impingement velocity.
		Sonic utilizes ambient blower air for most applications and if in-line air chillers are required, the net result is that Sonic is most often a far more efficient air quench.

		It's hard to decide what's weirder: that Penn State researchers are building a sonic refrigerator using acoustics to keep food cold, or that the U.S. Navy has teamed up with Ben & Jerry's to fund the project.
		The most common chemical refrigerants, chlorofluorocarbons (commonly known as CFCs), are ozone rippers, banned by a 1996 international convention.
		So the two organizations turned to a team lead by Steven Garrett, a Penn State professor of acoustics -- and former drummer -- who has been working for years to build a refrigerator that relies on sound waves, rather than toxins, to take the temperature down.
