Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
It is very similar to absorption refrigeration (note that the second letter is different) where an absorber absorbs the refrigerant vapour into a liquid. [1] The refrigerants used in absorption systems are ammonia , water, or methanol , etc, which all experience phase changes between the vapor and liquid states - the same as in vapor ...
Carl Georg Munters (22 March 1897 – 1989) was a Swedish inventor, most known for inventing together with Baltzar von Platen the gas absorption refrigerator now sold by Electrolux. He also invented and patented a method of making foamed plastic, which was later rediscovered by Dow Chemical Company and used to make Styrofoam. [1]
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...
A Crosley IcyBall with cold side ball on left, hot side ball on right. Icyball is a name given to two early refrigerators, one made by Australian Sir Edward Hallstrom in 1923, and the other design patented by David Forbes Keith of Toronto (filed 1927, granted 1929), [1] [2] and manufactured by American Powel Crosley Jr., who bought the rights to the device.
While we all like to treat the fridge as a safe-haven for all things food and drink, there are things you should in fact not put there. Storing the foods in the fridge won't cause any harm ...
It is also used in absorption chilling along with water (see absorption refrigerator). Solid LiBr is a useful reagent in organic synthesis . It is included into oxidation and hydroformylation catalysts; it is also used for deprotonation and dehydration of organic compounds containing acidic protons, and for the purification of steroids and ...
