Standards for Servicing and Repairing Compression Chillers in Advanced Cooling Systems

The standards for servicing and repairing compression chillers in advanced cooling systems form the foundation for maintaining optimal performance, reducing energy consumption, and extending equipment lifespan.

In today’s cooling systems, often used in large projects, smart buildings, and industrial facilities, traditional maintenance and repair approaches are no longer sufficient. Adhering to specific and precise standards not only prevents unexpected breakdowns but also enhances efficiency and reliability in various operating conditions.

Compression chillers are central to many central air conditioning systems, and since the thermal load in advanced buildings constantly changes, the system must be highly flexible and stable. In this regard, chiller repairs should be conducted based on standard checklists and defined time intervals.
These checklists typically include checking the health of the compressor, refrigerant pressure control, condenser cleaning, electrical current testing, inspecting the control board, and calibrating the sensors. Each of these steps requires specialized knowledge and precise tools.

In advanced cooling systems, the use of modern control technologies such as BMS (Building Management Systems) or PLCs has expanded the range of chiller functionality and complexity. Therefore, service and repair standards must also include the ability to analyze real-time data, troubleshoot software errors, and make advanced adjustments.
For example, if there is a mismatch between temperature sensor data and compressor commands, the technician must be able to access the settings or monitoring panel of the system, diagnose the issue, and correct it.

Another important aspect of standardization is the use of components and equipment approved by the chiller manufacturer. Advanced systems are sensitive to small changes in component specifications, and using non-standard or counterfeit parts can cause severe damage to the device.
Additionally, lubricants, refrigerants, and cleaning agents used in the service process must be fully compatible with the model and capacity of the device and meet international standards like ASHRAE, AHRI, or ISO.

Adhering to safety principles is also an inseparable part of chiller repair standards. Since compression chillers are installed in specific rooms or on rooftops in large projects, technicians are required to use personal safety equipment, electrical insulation tools, and follow instructions for working at heights or in confined spaces.

Moreover, the process of documenting services performed, periodic reporting, and tracking performance changes over time is an essential part of the maintenance standards in advanced cooling systems.

In summary, the standards for servicing and repairing compression chillers in advanced cooling systems result from integrating technical knowledge, practical experience, specialized equipment, and safety requirements. Strict adherence to these standards ensures continuous operation, high efficiency, and reduced additional costs in modern buildings and critical infrastructure.

Troubleshooting Methods and Component Testing in the Process of Repairing Compression Chillers

Troubleshooting methods and component testing in the repair process of compression chillers play a vital role in quickly and accurately diagnosing system problems. A compression chiller is one of the most complex cooling systems, using a series of technical components to carry out the refrigeration process.
Since the failure of any of these components can disrupt the overall system operation, using specialized methods and precise tools for troubleshooting is essential. In this article, we will explore some common methods for troubleshooting and testing components in the process of repairing a compression chiller.
One of the earliest steps in the troubleshooting process of a compression chiller is inspecting the visible signs of the device. Reduced cooling, unusual sounds, refrigerant leaks, or the sudden shutdown of the system can indicate problems with the components.

At this stage, using a checklist to assess the signs and behavior of the device can quickly identify potential issues. After detecting the symptoms, the technician should use precise measuring tools to gather more information about the system’s condition.

One of the most important tools in troubleshooting a compression chiller is a pressure gauge. Testing refrigerant pressure in various parts of the system, especially in the compressor, condenser, and evaporator, can indicate issues such as gas leaks, filter blockages, or compressor damage.
Low pressure in the condenser and high pressure in the evaporator typically suggest refrigerant leaks or problems with the expansion valve’s function. By using digital and analog pressure gauges, the pressure at different points in the system can be accurately tested and compared.

Testing the compressor is another essential step in troubleshooting a compression chiller. The compressor is the heart of the refrigeration system, and its failure can cause the system to stop entirely. To assess the compressor’s condition, the technician must use tools such as an ammeter to measure the current drawn by the compressor.

If the compressor’s current consumption is higher than usual, it may indicate issues with connections or a decrease in gas pressure. Additionally, testing the temperature and vibration of the compressor can provide more information about its health.
Along with pressure and current tests, inspecting and testing the control board is also crucial. Modern compression chillers are typically equipped with electronic boards that control the operation of many components. A malfunctioning control board can cause voltage fluctuations, sudden on/off cycles, or improper sensor function.
To test the control board, using digital tools to check the voltage and input/output signals is an important step in diagnosing problems. In some cases, repairing or replacing the control board may be necessary.

Finally, testing the expansion valve is an essential part of the compression chiller repair process. The expansion valve regulates the refrigerant flow to the evaporator, and its failure can disrupt the refrigeration process and reduce the system’s efficiency. The technician must use precise tools to check the refrigerant flow in the system. If the expansion valve is blocked or malfunctioning, it must be repaired or replaced.

Troubleshooting methods and component testing in the process of repairing a compression chiller require a combination of precise measuring tools, technical knowledge, and practical experience. By applying these methods and using advanced techniques, system issues can be quickly and accurately diagnosed and repaired.
