Product description
The principle of refrigeration is the exchange of heat and, in absorption liquid chilling, there are
four basic heat exchange surfaces: the evaporator, the absorber, the generator, and the condenser.
See Figure 1.
Like any refrigeration system, an absorption chiller uses evaporation and condensation to remove
heat. The single effect absorption cycle uses deionized water as the refrigerant and lithium bromide
(LiBr) as the absorbent. The entire process occurs in almost a complete vacuum.
Chiller components
The absorption chiller unit consists of the following components:
• Evaporator
• Absorber
• Condenser
• Generator
• Solution heat exchanger to heighten the cycle efficiency and piping to connect them
• Pumps to circulate the refrigerant and solution in the cycle
• Purge unit to purge non-condensable gas out of the machine
