This installation consists of two 415 kW reciprocating engine generators and an absorption chiller that produces 160 tons of 25F refrigeration from the engine waste heat. The components like absorber and generator perform the regular functions.
This article describes the.
Ammonia water absorption chiller. The dimensions of the absorption chiller illustrated on Fig. 1 are L W H 08 06 22 m and its mass is 350 kg. It contains 16 kg of ammonia and 8 kg of water.
Its evaporator is a vertical falling film shell and tube heat exchanger where the refrigerant flows through the tubes. 7 rânduri The ammoniawater absorption chiller named ago congelo generates cooling energy up to a coolant. Water-lithium bromide and ammonia-water.
Ammonia-water chillers are particularly interesting because of their low production and maintenance cost 5. Moreover the high pressure thermodynamic cycle is favorable for internal heat and mass transfer optimization reduction of the ammonia-water solution quantity lower hydraulic pressure drops and a compact final design. Ammonia water absorption chiller works with positive pressure Li-Br works with negative pressure reducing maintenance problems and making the machine to be more robust.
Ammonia water absorption chiller can work with extreme conditions high condensation temperature and. The single-effect ammoniawater absorption chiller illustrated schematically in Fig. 1 is designed to supply the chilled water for use in air-conditioning.
Flue gas produced by the combustion of fossil fuel is the heat source and air is the heat sink. In the ammonia-water absorption refrigeration system ammonia works as the refrigerant and water works as the absorbent. When ammonia leaves the generator in the vaporized state some particles of water vapor are also carried with it and these are removed in the analyzer and the rectifier.
The components like absorber and generator perform the regular functions. This article describes the. In the absorber this mixture of gases contacts water technically a weak solution of ammonia in water.
The gaseous ammonia dissolves in the water while the hydrogen which doesnt collects at the top of the absorber leaving the now-strong ammonia-and-water solution at the bottom. The hydrogen is now separate while the ammonia is now dissolved in the water. The next step separates the ammonia and water.
How Absorption Chiller Works First of all a mixture of around 50 lithium bromide and 40 water is pumped from the absorber through the heat exchanger and then up into the generator. This line is refereed to as the the weak solution line because the lithium bromide is mixed with water. Another common refrigerantabsorbent pair is ammonia as the refrigerant and water as the absorbent.
These fluids are more common in small residential applications. There are other refrigerantabsorbent combinations. This clinic however will focus on water as the.
The ammoniawater absorption chiller generates cooling energy up to -40 C. For this the chiller primarily requires heat which is generated during the industrial processes or from the CHP plant. Packed Towers are used for gas absorption including acid gases such as S02 HCl and others.
Packed Towers can also absorb solvents such as Alcohol and gases such as Ammonia. Almost any water soluble chemical can be removed from the gas using a Packed Tower. Some liquids like water have a great tendency for absorbing large amount of certain vapors NH3 and reduce the total volume quite.
The absorption chiller refrigeration system differs basically from vapor compression system only in the method of compressing the refrigerant. Implementation sectors for the Colibri absorption refrigeration plants. Our Ammonia Absorption Chillers can be introduced in any place where a certain amount of refrigeration is needed and where a heat source is available.
The main sectors are. A single stage ammonia-water absorption chiller with complete condensation is designed built and tested. The apparatus is designed for a cooling capacity of 2814 W which is obtained using.
The thermodynamic mathematical model of the transportation system is similar to the traditional ammoniawater absorption chiller. The main difference is that there exist three transportation conditions related to strong solution weak solution and liquid. About 3 of these are Industrial Chiller 0 are Industrial Air Conditioners.
A wide variety of ammonia water absorption chiller options are available to you such as local service location key selling points and applicable industries. Integrated ammoniawater absorption chiller. This installation consists of two 415 kW reciprocating engine generators and an absorption chiller that produces 160 tons of 25F refrigeration from the engine waste heat.
The 160 tons of refrigeration is supplied directly to.
