DETAIL
Main Heat Exchange Components of a Lithium Bromide Absorption Chiller:
  1. Evaporator
  2. Condenser
  3. Generator
  4. Absorber
Refrigerant Water Cycle:
Water vapor and concentrated lithium bromide solution are separated in the generator → The vapor condenses into water in the condenser → Passes through a throttle valve →
Evaporates and absorbs heat in the evaporator → Mixes with lithium bromide in the absorber to form a dilute solution → Returned to the generator.

Lithium Bromide Cycle (Performs the function of a compressor):
Water vapor is separated in the generator, forming a concentrated solution → Pressure is reduced through throttling → In the absorber, the solution absorbs water vapor and becomes a dilute solution → The dilute solution is pumped to increase pressure → Returned to the generator.

Advantages
  1. Simple structure with few mechanical moving parts; smooth operation and low vibration.
  2. Easy to operate, with a wide range of cooling capacity adjustment (stepless control from 10% to 100%).
  3. Low energy quality requirements: steam or hot water-driven units can utilize waste heat, residual heat, or other low-grade heat sources.
  4. Thermal energy-driven: power consumption is only 5% of that of a mechanical compression chiller with the same cooling capacity.
  5. Stable cooling efficiency when the heat source is stable, and capable of fully automated control.
Disadvantages
  1. Lithium bromide solution is corrosive to carbon steel, requiring regular maintenance and protection.
  2. The unit operates under vacuum conditions, requiring high airtightness; air ingress will cause performance degradation.
  3. Still requires cooling water for operation.
 
Conditions for Using Lithium Bromide Absorption Chillers:
Ø Energy-saving!!! No compressor required!!!
Ø Available waste steam pressure ≥ 30 kPa, or waste hot water temperature ≥ 80°C
Ø Waste heat source capacity > 500,000 kcal/hr (approx. 581 kW)
Ø Or equivalent fluid conditions such as waste gas, exhaust air, or wastewater with the above heat parameters
Ø Cooling capacity demand > 100 RT (≈ 350 kW)
Ø Required chilled water temperature ≥ 5°C
Ø Initial investment is approximately twice that of a conventional mechanical chiller
