The refrigeration system is an indispensable part of modern industry and life, however, some problems will inevitably occur during use, among which abnormal exhaust is a common one. This article will analyze the causes of abnormal exhaust gas in the refrigeration system in detail and give corresponding solutions.
1. Abnormal performance of exhaust of refrigeration system.
Abnormal exhaust gas in the refrigeration system is usually manifested as a decrease in the refrigeration effect, an increase in the load of the compressor, and fluctuations in the pressure of the pipeline. In severe cases, it can lead to compressor damage, refrigerant leakage, and other consequences.
2. The cause of abnormal exhaust of the refrigeration system.
1.Insufficient or excessive refrigerant.
Refrigerant is one of the most important components of a refrigeration system, and if there is not enough or too much refrigerant, it will lead to abnormal exhaust gas. Insufficient refrigerant can be caused by refrigerant leakage, compressor failure, etc.;Excessive refrigerant can be caused by overcharging or improper maintenance.
2.Compressor failure.
The compressor is the core equipment in the refrigeration system, and if the compressor fails, it will lead to abnormal exhaust gas. Compressor failure can be caused by wear and tear of bearings, cylinders, pistons, and other components, excessive clearance, or poor sealing.
3.Cooling water anomalies.
Cooling water is an important medium used to dissipate heat in the refrigeration system, and if the cooling water is abnormal, it will lead to abnormal exhaust. Cooling water abnormalities can be caused by poor water quality, excessive limescale, or poor water flow.
4.Clogged pipes or air leaks.
If the pipes in the refrigeration system are clogged or leaking, it will lead to abnormal exhaust gas. Pipeline blockage may be caused by scaling on the inner wall of the pipe, foreign body blockage, etc.;Pipeline leaks can be caused by poor sealing, material defects, etc.
5.Control system failure.
The control system is an important part of the refrigeration system used to control the refrigerant cycle, and if the control system fails, it will lead to abnormal exhaust gassing. Control system failures can be caused by damage to the circuit board, sensor failure, or actuator failure.
3. Solutions to abnormal exhaust of refrigeration system.
1.For the problem of insufficient or excessive refrigerant, it is necessary to check whether the refrigerant charge is appropriate, if it is insufficient, it needs to be replenished, and if it is excessive, it needs to be discharged. At the same time, it is also necessary to check whether there is a fault in the compressor and other components, and if so, it needs to be repaired or replaced in time.
2.For the problem of compressor failure, it is necessary to check whether the various parts of the compressor are operating normally, and if there is a problem, it needs to be repaired or replaced in time. At the same time, it is also necessary to check whether the lubricating oil of the compressor is sufficient, whether it needs to be replaced, etc.
3.In view of the problem of abnormal cooling water, it is necessary to check whether the quality and flow rate of the cooling water are normal, and if there is a problem, it needs to be cleaned or replaced in time. At the same time, it is also necessary to check whether the equipment such as cooling towers or cooling water pumps is operating properly.
4.For the problem of pipeline blockage or air leakage, it is necessary to check whether the patency and sealing of the pipeline are good, and if there is a problem, it needs to be cleaned or replaced in time. At the same time, it is also necessary to check whether the material and welding quality of the pipeline are qualified.
5.In view of the problem of control system failure, it is necessary to check whether the circuit board, sensors and actuators of the control system are operating normally, and if there is a problem, it needs to be repaired or replaced in time. At the same time, regular maintenance and servicing of the control system is required.
4. Preventive measures.
In order to reduce the problem of abnormal exhaust gas in the refrigeration system, the following precautions can be taken:
1.Regularly inspect and maintain various components in the refrigeration system, including compressors, condensers, evaporators, piping, etc.
2.Regularly replace the lubricating oil and clean the impurities inside the pipeline to ensure the normal operation of the compressor.
3.Regularly check the quality of cooling water and the operation status of equipment such as water pumps to ensure the normal circulation of cooling water.
