Vapor Absorption Cooling System
Vapor Absorption Systems or the use of Absorption Chillers heat source to produce a cooling effect. Compression vapor refrigerant in the system. Absorption chillers are mainly used in areas with access to cheap heat, source or process of recycling of heat. Absorption chillers have few moving parts and can mean less noise and vibration, especially in commercial buildings.
The process of vapor absorption requires two substances with strong chemical affinity at low temperatures. Produces absorption chillers can be of two types:
- The use of Lithium Bromide absorbent and water (refrigerant) for chilled water 5C and above.
- With the help of Water (absorbent) and Ammonia (refrigerant for temperatures below 5C. secondary fluid (brine) is required to transfer heat to ammonia.
Absorption Chillers can be one effect or a multiple effect machines; the effectiveness of the multiplier effect of the machines above. In India, one effect and double-effect machines are manufactured. Triple-effect absorption of machines available international manufacturers.
Most of absorption chillers used in India for chilled water with the help of LiBr and water. One machine capacity of over 1200 TR. Both heated pool, steam and shot the direct model is widely used. A small amount of refrigerating units using ammonia and water, as well as in the operation...
