In refrigeration systems, some parts are more susceptible to wear due to continuous use, temperature variations and external factors such as dust, humidity and lack of maintenance. Knowing these parts is essential to prevent failures and ensure the proper functioning of the equipment. See below the main ones:
1. Compressor
The compressor is the heart of the refrigeration system. It compresses the refrigerant gas and circulates it throughout the system. Because it is constantly operating and under pressure, it tends to be one of the parts that suffers the most wear over time. Signs of failure include abnormal noises, overheating and a drop in cooling efficiency.
2. Air filters
Air filters are responsible for retaining impurities and particles from the air before it circulates through the system. When they become saturated, they impair performance, increase energy consumption and overload the system. Therefore, they need to be cleaned frequently or replaced, depending on the model.
3. Fans and bearings
Fans (both internal and external) and their bearings work continuously to ensure air circulation. Over time, the accumulation of dirt, mechanical wear and lack of lubrication can cause noise, vibrations and even equipment shutdown.
4. Expansion valve
The expansion valve controls the amount of gas that enters the evaporator. Over time, it can become blocked, leak or malfunction due to dirt or mechanical failures, directly affecting refrigeration performance.
5. Pipes and connections
Copper pipes and connections that carry refrigerant gas can corrode, crack and leak — especially in environments with salty air or where the system was not properly installed. Gas leaks compromise the entire operation of the system and need to be fixed urgently.
Conclusion
Keeping preventive maintenance up to date is essential to extend the life of these parts and avoid unexpected shutdowns. If you notice any sign of strange noise, loss of efficiency or bad smell, it is recommended to call a specialized technician to check the system. Taking good care of these parts ensures savings, comfort and safety when using your refrigeration system.
