Absorption Water Chiller

Discussion of the fundamentals of the refrigeration cycle as it pertains to an absorption water chiller.  

Topics include:

• Absorption refrigeration cycle (generator or concentrator, condenser, evaporator, absorber, heat exchanger)
• System fluids (water, lithium bromide)
• Equilibrium chart
• Single-effect versus double-effect chillers
• Indirect-fired versus direct-fired chillers
• Chiller/heaters
• Capacity control methods (energy valve, AFD)
• Causes of crystallization and methods of prevention
• Purge operation
• General maintenance considerations (corrosion inhibitors)
• Cooling-water temperature limitations
• Combination gas-and-electric plants
• Special considerations for direct-fired chillers
• ASHRAE Standard 15
• ARI Standard 560
