溴化锂是一种无机化合物，化学式为LiBr，以其卓越的吸湿性而闻名——它能迅速吸收周围环境中的水蒸气。这一特性使其成为吸收式制冷系统中的理想吸收剂，作为驱动制冷循环的工作流体。与氯氟烃或氢氟烃等传统制冷剂不同，溴化锂无毒、不可燃且对环境友好，既不会破坏臭氧层，对全球变暖的贡献也微乎其微。在吸收式制冷机中，浓溴化锂溶液流经吸收器部分，吸收制冷剂蒸气（水）后变为稀溶液，并将吸收热释放到冷却水回路中。随后，稀溶液被泵送至发生器，在那里通过热能（通常来自蒸汽、热水或废热）将水蒸气驱出，从而再生出浓溴化锂以供下一循环使用。这一巧妙的热力学循环无需机械蒸气压缩机即可实现高效制冷，与传统蒸气压缩系统相比，显著降低了电力消耗。

Beyond its role in absorption chiller technology, lithium bromide is also used in other industrial applications such as air conditioning in large commercial buildings, pharmaceutical drying processes, and chemical synthesis. One of the key advantages of LiBr over alternative absorbents is its high solubility in water and its ability to maintain stable performance across a wide range of temperatures and concentrations. Additionally, lithium bromide has a very high affinity for water vapor, which translates into superior dehumidification and cooling capacity per unit volume of solution. When properly maintained with the correct balance of corrosion inhibitors, a lithium bromide system can operate reliably for decades with minimal chemical degradation. For businesses evaluating absorption cooling options, understanding the fundamental properties of lithium bromide is essential to appreciating why it remains the dominant absorbent in commercial and industrial absorption chillers worldwide.

溴化锂吸收式冷水机组基于热力学循环运行，利用热能生产冷冻水，这与依靠电力驱动的压缩式冷水机组有本质区别。在标准单效循环中，系统由四个主要部件组成：发生器、冷凝器、蒸发器和吸收器。循环从发生器开始，热源（如低压蒸汽、热水或天然气）加热稀释的溴化锂溶液，使水蒸气从溶液中分离出来。水蒸气进入冷凝器，由独立的冷却水回路冷却并凝结为液态水。液态制冷剂随后流入蒸发器，该蒸发器在深度真空状态下运行，使水在极低温度下蒸发，并从冷冻水回路中吸收热量，从而产生所需的制冷效果。最后，蒸发器中的水蒸气被吸入吸收器，在此被浓缩的溴化锂溶液重新吸收，稀释后的溶液再被泵送回发生器，循环重复进行。这一无缝循环仅利用热能及少量用于泵的电力即可实现持续制冷，与传统系统相比，显著降低了电力消耗。

For applications requiring higher energy efficiency, double-effect absorption chillers introduce a second generator stage that captures and reuses heat that would otherwise be rejected. In a double-effect configuration, the heat released during condensation in the first stage is used to drive additional vapor generation in a second stage, effectively boosting the system's coefficient of performance (COP) from approximately 0.7 for single-effect units to a range of 1.0–1.4. These single-effect and double-effect cycles provide flexibility for project designers, allowing them to match the chiller configuration to the available heat source temperature and quality. Low-grade waste heat at around 85–95°C is sufficient for single-effect units, while higher temperature heat sources at 130–180°C can be utilized more efficiently in double-effect designs. Understanding these operational principles is crucial for facility managers and engineers who are evaluating LiBr absorption chiller technology as a solution for reducing energy costs and carbon footprints. The ability to leverage steam, hot water, or even direct exhaust gases as the driving energy source makes these systems exceptionally versatile across many industrial sectors.

Shanghai Oujin Industrial Co., Ltd. produces lithium bromide solution that is formulated to deliver outstanding performance characteristics demanded by modern absorption chiller applications. One of the most important attributes of the company's product is its exceptionally high absorption rate, which enables more efficient mass transfer in the absorber and allows chillers to achieve their rated cooling capacity with less solution inventory. This high absorption efficiency translates directly into smaller equipment footprints or increased capacity from existing machines, offering tangible value to system operators. Additionally, Oujin's lithium bromide is manufactured with strict control over impurity levels, particularly metallic contaminants such as iron, copper, and chromium that can catalyze corrosion within the chiller's internal surfaces. The result is a product that exhibits remarkably low corrosion rates when used with the recommended inhibitor package, helping to extend the service life of expensive chiller components such as heat exchanger tubes, pump seals, and vessel walls.

Beyond purity and absorption performance, Oujin's lithium bromide solution is engineered for long-term stable performance under the demanding operating conditions typical of industrial refrigeration and HVAC systems. The company uses proprietary stabilization technology that prevents solution degradation during prolonged exposure to high temperatures in the generator section, ensuring that the chemical composition remains consistent cycle after cycle. This stability reduces the frequency of solution replacement and minimizes operational interruptions, which is particularly important for mission-critical cooling applications in data centers, pharmaceutical plants, and food processing facilities. Furthermore, Oujin offers a comprehensive range of additive packages, including advanced corrosion inhibitors and pH buffers, that are pre-mixed into the solution to simplify maintenance procedures for end users. Each batch is tested for density, alkalinity, inhibitor concentration, and impurity levels before shipment, and the company provides a detailed certificate of analysis with every delivery. By choosing Oujin's high-quality lithium bromide, operators benefit from long service life of both the solution and the chiller equipment, resulting in lower total cost of ownership over the system's operational lifespan.

Even the best-maintained absorption chiller can occasionally encounter operational problems, and recognizing the early warning signs is critical to preventing costly downtime. One of the most frequently reported issues is low absorption efficiency, which typically manifests as a gradual decline in cooling capacity or an inability to reach the setpoint chilled water temperature. This condition is often caused by contamination of the lithium bromide solution with non-condensable gases such as nitrogen or oxygen, which accumulate in the absorber and interfere with the mass transfer of water vapor into the solution. Another common problem is the formation of scale or sludge deposits on heat exchanger surfaces, which reduces heat transfer efficiency and forces the system to work harder to achieve the same cooling output. Diagnosing these conditions requires systematic checking of solution concentration, temperature profiles across each component, and vacuum level readings to pinpoint the root cause accurately.

Vacuum issues represent another major category of faults in LiBr absorption chillers, since the entire cycle depends on maintaining a deep vacuum — typically in the range of 5–10 mmHg absolute — in the evaporator and absorber sections. Even a small air leak can dramatically degrade performance by increasing the partial pressure of non-condensable gases, which impedes absorption and raises the evaporation temperature. Common leak points include gaskets, valve stems, sight glass seals, and pump shaft seals, and locating them often requires helium leak detection or ultrasonic testing. Crystallization is a third serious problem that occurs when the lithium bromide solution becomes too concentrated or drops below a critical temperature, causing solid crystals to form and block solution flow paths. This can happen during low-load operation, improper shutdown procedures, or when cooling water temperatures fall too low. Finally, erosion and corrosion of internal components can result from improper inhibitor chemistry, excessive oxygen infiltration, or prolonged operation at elevated temperatures beyond design limits. Shanghai Oujin Industrial Co., Ltd. provides comprehensive technical support to help customers diagnose and resolve these issues, offering solution analysis services, inhibitor adjustment recommendations, and guidance on proper operating procedures to prevent recurrence.

Proactive maintenance is the most effective strategy for ensuring long-term reliability and efficiency of any absorption chiller system, and it begins with regular vacuum level verification. Operators should check the vacuum at least once per week using a calibrated absolute pressure gauge or a digital vacuum transducer, logging readings to detect gradual deterioration that may indicate a developing leak. Any reading that deviates from the manufacturer's specified range should be investigated immediately, as even small vacuum losses can significantly impair cooling performance. In parallel with vacuum monitoring, the concentration of the lithium bromide solution should be measured routinely using a refractometer or by sampling and laboratory analysis, since concentration directly affects both absorption capacity and the risk of crystallization. Ideally, the solution concentration should be maintained within the range recommended by the chiller manufacturer for the specific operating conditions, and adjustments should be made by adding either distilled water (to dilute) or fresh concentrated LiBr (to strengthen) as needed.

Equally important is the regular addition and monitoring of corrosion inhibitor chemicals, which protect the metal surfaces inside the chiller from attack by the bromide ions in the solution. Oujin recommends that customers test the inhibitor concentration and pH level of the solution on a monthly basis, using test kits or sending samples to the company's laboratory for comprehensive analysis. The pH should be maintained in the slightly alkaline range, typically between 9.5 and 10.5, to minimize corrosion of copper and steel components while preserving the effectiveness of the inhibitor package. Operators should also perform annual visual inspections of the chiller's internal components, including heat exchanger tubes, spray nozzles, and solution strainers, cleaning or replacing parts as necessary. Keeping a detailed maintenance log that documents all measurements, adjustments, and repairs creates a valuable historical record that can help identify emerging trends before they escalate into major failures. For customers who prefer a hands-off approach, Shanghai Oujin Industrial Co., Ltd. offers scheduled solution analysis and replenishment services, ensuring that the system always operates with optimal chemistry.

The versatility of lithium bromide absorption chillers makes them suitable for a remarkably wide range of applications, from large-scale HVAC systems in commercial buildings to specialized industrial refrigeration processes. In the commercial sector, LiBr chillers are frequently installed in hospitals, universities, hotels, and office complexes where the demand for cooling coincides with the availability of waste heat from cogeneration plants, solar thermal collectors, or district heating networks. These installations take advantage of the chiller's ability to use low-grade heat that would otherwise be discarded, converting it into valuable cooling capacity and dramatically improving overall facility energy efficiency. For example, a hospital with a combined heat and power system can route engine jacket water or exhaust heat to an absorption chiller, producing chilled water for air conditioning without increasing the electrical load on the grid. Similarly, many universities have adopted LiBr technology as part of their sustainability initiatives, integrating absorption chillers into campus district energy systems to reduce carbon emissions and operating costs simultaneously.

Industrial waste heat recovery represents one of the most compelling applications for lithium bromide absorption chillers, particularly in energy-intensive sectors such as chemicals, petrochemicals, steel manufacturing, and food processing. In these environments, furnaces, dryers, boilers, and other process equipment generate substantial quantities of waste heat that can be captured and used to drive absorption cooling. The chilled water produced can then be employed for process cooling, product storage, or facility air conditioning, creating a valuable energy cascade that reduces both fuel consumption and electrical demand. Additionally, LiBr absorption chillers are finding growing adoption in data centers, where the need for year-round cooling is constant and the availability of waste heat from servers and IT equipment provides an excellent heat source for absorption cycles. By integrating absorption chillers with existing cooling infrastructure, data center operators can achieve significant reductions in power usage effectiveness (PUE) and contribute to corporate sustainability goals.
