• The four main heat exchange components of an absorption chiller are:
   1. Evaporator
   2. Condenser
   3. Generator
   4. Absorber
• Refrigerant water cycle:
   The generator separates into water vapor and concentrated lithium bromide solution → condensed into water in the condenser → throttled → refrigerated in the evaporator → combined with lithium bromide in the absorber as dilute solution → returned to the generator.
• Lithium bromide cycle (function of the compressor):
   The generator separates water vapor into concentrated solution → throttled to reduce pressure → absorber absorbs water vapor and becomes dilute solution → pumped to increase pressure → returned to the generator.
• Advantages:
   ① Simple structure, fewer mechanical moving parts, smooth operation, minimal vibration.
   ② Convenient operation, large range of refrigeration capacity adjustment, capable of achieving stepless adjustment within 10% to 100% range.
   ③ Steam and hot water types have low requirements for energy quality, can utilize waste heat, residual heat, and other low-grade heat energy.
   ④ Powered by thermal energy, the power consumption of the refrigeration unit is only 5% of that of the compressor unit with the same refrigeration capacity.
   ⑤ When the heat source is stable, it can effectively ensure the efficiency of refrigeration and achieve automation control.
• Disadvantages:
   ① Lithium bromide solution is corrosive to carbon steel, maintenance and care are required.
   ② The unit operates under vacuum for a long time, strict requirements on sealing, if air enters, it will cause refrigeration capacity decay.
   ③ Still requires cooling water.
• Conditions for using lithium bromide absorption chillers:
   Ø Energy-saving!!! No compressor required!!!
   Ø Hot water with waste heat steam pressure not less than 30 kPa or waste heat hot water temperature not less than 80°C.
   Ø Waste heat source with over 500,000 kcal/hr.
   Ø Or equivalent fluid conditions such as waste gas, sewage, etc., with the above heat source conditions.
   Ø Demand for refrigeration capacity greater than 100 RT (=350 kW).
   Ø Refrigeration demand above 5°C.
   Ø Initial investment is approximately double that of traditional compression chillers.
