In vapour absorption refrigeration systems most commonly these two pairs are used.
- Water-Lithium Bromide (H2O – LiBr) system for above 0ºC applications such as air conditioning. Here water is the refrigerant and lithium bromide is the absorbent.
- Ammonia-Water (NH3 – H2O) system for refrigeration applications with ammonia as refrigerant and water as absorbent.
About VARS:
- In vapour absorption refrigeration system (VARS), the components used are Evaporator, Absorber, Pump, Generator, Condenser, Expander.
- In vapour compression refrigeration system (VCRS), the components used are Evaporator, Compressor, Condenser and Expander.
- Thus generator, absorber and pump are absent in VCRS.
- In VARS less mechanical work is used compared to VCRS.
- In the vapour absorption system, the compressor is replaced with the absorber, pump and generator.
