An Introduction to Absorption Chiller Repair in Tehran and Understanding Its Main Components

Repairing absorption chillers involves a detailed examination of parts such as the generator, absorber, condenser, and internal pumps to restore the system’s operation to a standard condition. Alongside this, servicing absorption chillers plays a vital role in extending the device’s lifespan and typically includes circuit cleaning, leakage inspection, and adjustment of the lithium bromide solution. Absorption chiller repair in Tehran is carried out by specialized teams using advanced equipment.

Absorption chillers, as one of the commonly used cooling systems in industrial, commercial, and building projects, hold a special place among HVAC equipment. Unlike compression chillers that use compressors to compress the refrigerant, absorption chillers operate based on thermal and chemical processes in which compounds such as lithium bromide or ammonia play key roles.

Since the operation of these systems strongly depends on the precise balance of internal components and operating conditions, repairing absorption chillers requires a deep understanding of their structure and high skill in analyzing the performance of various parts.

The Importance of Absorption Chiller Repair in Large Cities Like Tehran
In a large city like Tehran, where absorption chillers are commonly used in hospitals, hotels, large residential complexes, and industrial centers, the importance of proper and principled absorption chiller repair becomes even more evident. The variable climate, fluctuations in municipal gas pressure, and specific operating conditions of the devices in this region have made maintenance and repair of these systems an essential expertise.

Specialists working in absorption chiller repair in Tehran must, in addition to technical skills, be fully familiar with climatic challenges and installation and maintenance limitations within the urban fabric.

The Importance of Knowing the Main Components of an Absorption Chiller as the First Step in Servicing
Familiarity with the main components of an absorption chiller is the first step in its repair and maintenance. Each absorption chiller consists of four key parts: the generator, condenser, absorber, and evaporator. The generator uses a heat source to convert the lithium bromide solution into refrigerant vapor.

The refrigerant vapor then enters the condenser and, after condensation, evaporates in the evaporator to create the cooling process. Subsequently, the vapor is again absorbed into the solution in the absorber, and the cycle repeats. Alongside these components, pumps, control valves, measurement systems, and solution transfer lines also play vital roles in the system’s correct operation.

In the absorption chiller repair process, detailed familiarity with these parts helps the technician quickly identify the problem area and take effective action. For example, if cooling efficiency has decreased, the issue may lie in the absorber or the system vacuum level. If solution leakage occurs, inspecting the generator connections and heat exchangers is prioritized.

For this reason, any repair action without a precise understanding of the internal mechanism may not only fail to solve the problem but also cause further damage to the system.

Absorption Chiller Repair in Tehran
Overall, absorption chiller repair in Tehran is a specialized and multi-layered process requiring technical knowledge, field experience, familiarity with local conditions, and use of precise equipment. With proper knowledge of internal components and regular interaction with maintenance teams, costly failures can be prevented and stable, reliable device operation ensured.

Common Reasons for Absorption Chiller Service and Signs of Malfunction
Due to their complex structure and high dependency on precise balance between components and operating conditions, absorption chillers require regular and accurate servicing. Contrary to the common misconception that these systems need less maintenance due to the absence of a compressor, the reality is that neglecting periodic service drastically reduces their performance and causes severe failures.

Servicing absorption chillers is not only necessary to improve cooling efficiency but also indispensable to prevent serious damage to internal components and extend the device’s useful life.

One of the most common reasons for the need for absorption chiller service is a drop in system vacuum. This vacuum loss, usually caused by leaks at connection points or damage to gaskets and internal seals, reduces the capacity of the absorbent solution (such as lithium bromide) to absorb refrigerant vapor.

As a result, the device’s cooling drastically drops and the system can no longer meet the cooling demand. In such cases, re-evacuation, leak repair, and working solution recovery are among the important service actions.

Scaling formation in heat exchangers is another frequent cause requiring absorption chiller service and repair. The flow of hard water through the condenser or evaporator over time leads to mineral deposit buildup that disrupts heat transfer and impairs system performance.

This issue is usually accompanied by signs such as increased outlet water temperature, excessive thermal energy consumption, and longer times to reach the desired temperature. In periodic service, chemical cleaning of the exchangers and inspection of inlet water quality are highly important.

Other signs indicating the need for absorption chiller service include temperature fluctuations, unusual noises in pumps, abnormal pressure changes, instability in the absorption process, and a distinctive odor caused by lithium bromide leakage. Ignoring these signs may lead to damage of sensitive components such as circulation pumps, sensors, or even harm to the internal metal structure.

Absorption chiller service is a preventive and intelligent measure aimed at maintaining stable performance, avoiding early failures, and optimizing energy consumption. In cities like Tehran where the cooling systems experience high workload and diverse operating conditions, regular servicing relying on expert personnel and precise tools not only helps preserve system efficiency but also prevents costly future repairs.

Initial Troubleshooting Steps to Start Absorption Chiller Repair
The absorption chiller repair process begins with a key and sensitive stage: initial troubleshooting. This phase forms the foundation for decision-making regarding subsequent repair actions and must be conducted carefully, with technical awareness and use of specialized tools.

Since absorption chillers are complex systems highly dependent on balance between pressure, temperature, solution composition, and pump performance, any diagnostic error can lead to incorrect interventions and ultimately further damage to the device. Therefore, principled troubleshooting is the first vital step in the absorption chiller repair path.

The troubleshooting process usually starts with a visual and auditory inspection of the device’s condition. Presence of signs such as unusual pump noises, abnormal vibrations, characteristic odors caused by solution leaks, or signs of corrosion and leakage on the body can provide the technician with the first clues. These inspections help categorize the fault broadly, for example mechanical or chemical, and guide a more detailed analysis path.

Next, key operational parameters of the system such as pressure, temperature at critical points (like the generator, absorber, and evaporator), and internal vacuum level are checked. Absorption chillers require maintaining a certain vacuum level for correct operation. Vacuum loss due to leaks is one of the main reasons for efficiency reduction or complete system shutdown. Using precise gauges and leak tests, the technician can identify the location or area suffering from pressure loss.

Also, the condition of the lithium bromide or ammonia solution, used as the absorbent, must be checked for concentration, contamination, or crystallization. In many cases, improper system operation is due to changes in the chemical properties of the solution and reduced absorption capacity. This issue can be diagnosed by sampling and examining the color, viscosity, or deposits within the solution.

Next, the proper functioning of moving components such as solution pumps, control valves, and electronic control equipment is evaluated. Even the slightest malfunction in these parts can cause disharmony in the absorption and evaporation cycle, leading to problems throughout the system. At this stage, paying close attention to sensor signals and comparing them with the normal values recorded in the device’s catalog is very important.

Finally, the results of the initial troubleshooting are documented in a detailed report so that the subsequent technical actions—repair or replacement of parts—can be performed correctly and without wasting time. In fact, the initial troubleshooting phase to begin absorption chiller repair is like an accurate diagnosis before treatment; if done carefully, the success rate of the final repair will be very high, preventing recurring costs and failures.

Technical and Specialized Actions in the Absorption Chiller Repair Process
Technical and specialized actions during absorption chiller repair include a set of precise and engineered operations carried out based on the troubleshooting results. These actions may include repairing or replacing solution and refrigerant pumps, welding and sealing leak points, restoring the lithium bromide solution by filtration and adjusting concentration, and in some cases, chemical cleaning of heat exchangers to remove deposits.

Additionally, inspection and readjustment of sensors, controllers, and electronic valves are other specialized repair stages that directly affect restoring the system’s proper function. All these actions must be performed by experienced technicians using standard tools to not only fully resolve defects but also prevent new issues in the chiller’s operating cycle.

Key Points After Absorption Chiller Repair to Extend Device Lifespan
After completing absorption chiller repair, attention to preventive maintenance and correct operation plays a very important role in increasing the useful life and preserving system efficiency. Regular scheduled services should be planned so that all system components are regularly inspected, cleaned, and adjusted to prevent sudden failures.

Continuous monitoring of key parameters such as pressure, temperature, and vacuum level in different sections of the absorption chiller helps timely detection of anomalies and prevents possible damage. Furthermore, the quality and concentration of the lithium bromide solution should be regularly evaluated and corrected if necessary to maintain the system’s absorption and heat transfer capabilities.

Training operators and maintenance teams to familiarize them with proper device operation, how to respond to system alerts, and safety protocols is another vital post-repair measure. Operators who are well acquainted with the technical specifications and operating conditions of the absorption chiller can effectively prevent operational errors and improve the overall device performance.

Finally, establishing a comprehensive and continuous maintenance program that includes technical inspections, checking the condition of moving parts, and timely replacement of filters and consumable components is the key to ensuring stable operation and high energy efficiency after absorption chiller repair. Such an approach reduces operating costs and ensures the device will work trouble-free for many years.
