Absorption Chillers
Specification: Steam & Direct-Fired Heat Driven
Thermal energy cooling systems utilizing low-pressure steam, hot water, or natural gas for off-peak energy savings.
Engineering Scope & Overview
Absorption chillers use heat energy instead of mechanical electricity to drive the refrigeration cycle. Western Mechanical Inc. provides comprehensive maintenance on lithium bromide and ammonia absorption chillers, lithium bromide crystallization recovery, and vacuum integrity testing.
WMI Field Protocol & Certified Best Practices
- Lithium bromide chemical concentration and inhibitor titration
- High-vacuum purge pump servicing and hermetic leak testing
- Heat exchanger descaling on steam and hot water generator bundles
- Burner modulation and combustion efficiency tuning on direct-fired units
Frequently Asked Questions
- What causes crystallization in a lithium bromide absorption chiller?
- Crystallization happens when the lithium bromide solution concentration becomes too high or solution temperature drops too quickly, often caused by rapid condenser water temperature drop or power interruptions.
- How does Western Mechanical de-crystallize an absorption chiller?
- We use controlled steam or heat injection, internal bypass flushing, and chemical titration without damaging internal tube bundles or rupturing rupture discs.
- Why are absorption chillers ideal for co-generation and central energy plants?
- They utilize waste steam, turbine exhaust heat, or landfill gas to produce high-tonnage chilled water, completely bypassing high peak-hour electrical demand charges from electric utilities.
