1. The principle of suction and exhaust in the refrigeration system is to suck the refrigerant from the low-pressure side through the suction action of the compressor, and then compress it into high-pressure gas through the compression action of the compressor, and finally discharge the high-pressure gas out of the refrigeration system through the exhaust port.
2 Abnormal suction and exhaust of the refrigeration system is usually caused by the following reasons:
2.1. Compressor failure: The compressor is the core component of the refrigeration system, if the compressor fails, it will cause the refrigerant to fail to circulate normally, thus affecting the refrigeration effect.
2.2. Insufficient refrigerant: Refrigerant is an important medium in the refrigeration system, if the refrigerant is insufficient, it will lead to a decrease in the refrigeration effect.
2.3. Condenser failure: The condenser is a heat dissipation device in the refrigeration system, if the condenser fails, it will lead to poor heat dissipation of the refrigerant, which will affect the refrigeration effect.
2.4. Expansion valve failure: The expansion valve is a throttling device in the refrigeration system, if the expansion valve fails, it will lead to abnormal refrigerant flow, which will affect the refrigeration effect.
2.5. Pipeline blockage: The pipeline is the channel for the flow of refrigerant in the refrigeration system, if the pipeline is blocked, it will cause the refrigerant to flow normally, thus affecting the refrigeration effect.
3. For the abnormal suction and exhaust problems of the refrigeration system, the following measures can be taken to investigate and deal with them:
3.1 Check whether the compressor is working properly, if the compressor is found to be faulty, it needs to be replaced or repaired in time.
3.2. Check whether the refrigerant is sufficient, if it is insufficient, it needs to be added in time.
3.3. Check whether the condenser is working properly, and if it is found that the fault needs to be repaired or replaced in time.
3.4. Check whether the expansion valve is working normally, and if a fault is found, it needs to be repaired or replaced in time.
3.5. Check whether the pipeline is blocked, if it is found to be blocked, it needs to be cleaned up in time.
