Overview
Steam-operated lithium bromide absorption chiller is a large industrial cooling unit driven by saturated steam, using lithium bromide solution as the absorbent and water as the refrigerant. It reduces electrical consumption and operating costs in sites with available steam and helps smooth peak-valley power demand.

Information
Suitable steam supply: saturated steam at 0–8 bar (G), typically LP or MP in industrial plants. Low-cost steam sources (WHRB/HRSG waste-heat steam, process extraction steam) are recommended. Based on steam heat grade the product is available in two types:

• Steam-Operated Double Effect Lithium Bromide Absorption Chiller: Saturated steam pressure range 2.5–8 bar (G); high energy performance with COP up to 1.55.
• Steam-Operated Single Effect Lithium Bromide Absorption Chiller: Saturated steam pressure range 0–2.5 bar (G); lower COP vs. double effect but applicable to lower-grade heat and capable of recycling steam around 100 °C.

Function
Provide chilled water above 0 °C for HVAC, process cooling and industrial applications.

Capacity Range
233–11,630 kW (20–1000×10^4 kcal/h).

Driving Sources
Saturated steam, 0–8 bar (G). Recommended: LP/MP steam, WHRB/HRSG waste-heat steam, steam extraction from processes.
