Solar Absorption Chiller

High-efficiency, clean cooling solution empowering sustainable buildings and renewable energy systems

Product Overview

The solar absorption chiller is a lithium bromide-based absorption refrigeration system powered primarily by solar energy. It operates on the principle of water vapor absorption by lithium bromide solution. Solar collectors convert solar radiation into thermal energy, which heats the solution in the generator, causing the separation of water and lithium bromide. The resulting water vapor is condensed in the condenser and then evaporates in the evaporator, absorbing heat and providing cooling. The vapor is then absorbed back by the lithium bromide solution, completing the cycle. This system is known for its energy efficiency, environmental friendliness, and zero carbon emissions, making it ideal for energy-saving buildings and integrated renewable energy projects in sun-rich regions.

Advantages

• Solar-powered operation: Utilizes solar energy as the primary heat source, eliminating the need for fossil fuels and achieving zero emissions.
• Smart anti-freezing system: Multi-level interlock protection ensures safe operation in low-temperature environments.
• Strong vacuum performance: Multi-ejector and water-head design enables rapid vacuum creation and effective oxygen corrosion prevention.
• Reliable piping design: Simplified and compact structure with fewer valves reduces potential leakage points and lowers maintenance needs.
• Intelligent anti-crystallization system: Integrated temperature and potential difference control prevents lithium bromide crystallization through automatic dilution.
• High part-load adaptability: Refrigerant water storage adjusts automatically to varying load conditions, improving operational efficiency.
• Enhanced energy-saving features: Isooctanol additives and economizer improve absorption efficiency and reduce energy consumption.
• Integral sintered sight glass: Unit's sealing performance exceeds national standards, ensuring long-term operational stability.
• Eco-friendly corrosion inhibitor: Uses lithium molybdate (Li₂MoO₄), a non-toxic, heavy metal-free inhibitor for enhanced sustainability.
• Efficient heat exchange components: Hydrophilic-treated evaporator and absorber tubes ensure superior heat transfer and lower energy use.
• Frequency-controlled operation: Smart variable-speed control of key components adapts to actual load conditions, reducing energy use.
• Stainless steel plate heat exchanger: Compact design, high heat recovery efficiency, energy-saving, and over 20 years of service life.

Applications

• Central cooling systems for green and nearly-zero energy buildings
• Energy retrofits for public facilities (e.g., schools, hospitals) in high-sunlight regions
• Industrial plants and data centers utilizing solar waste heat
• Energy-saving upgrades for central air conditioning in commercial complexes (malls, airports, hotels)
• Auxiliary cooling for renewable energy-based tri-generation systems
• … and more
