5 ways to avoid liquid shock and noise problems of refrigerators

The liquid shock of the refrigerator is a malfunction, that is, when the compressor enters the liquid refrigerant, moisture or other liquids, a knock phenomenon will occur. The compressor will be damaged or the compression efficiency will decrease. And cause serious consequences, including the company’s refrigeration capacity can not meet the actual demand, and cause the company’s operating losses and so on.

Then, the refrigerating machine operation and maintenance personnel of the enterprise should understand where the liquid hammer problem of the refrigerator is and how to avoid it. Today, the editor of Shenchuangyi Refrigeration will talk about how to avoid the liquid hammer problem of the refrigerator and the noise problem. , The following five solutions are proposed, hoping to help the personnel responsible for the operation and maintenance of the refrigerator in the enterprise.

The first method to avoid the liquid shock and noise problems of the refrigerator: In the refrigerator system, after the evaporator, there must be a gas-liquid separation device.

why? Because the evaporator does not necessarily evaporate completely during the evaporation process, there will be a certain amount of liquid refrigerant. In this case, it will cause liquid, and even other non-refrigerant liquids, so compression will occur. The liquid hammer phenomenon of the machine.

Liquid hammer will cause the noise of the refrigerator, especially the noise of the compressor, to become very loud. This is the legendary liquid hammer phenomenon, so it will bring serious consequences.

The second method to avoid liquid shock and noise problems of the refrigerator: The refrigerant filling amount or the temperature of the refrigerated lubricating oil can also cause liquid shock. If you want to tell from the source, you should avoid it. Too much refrigerant is charged, or to ensure the normal operation of the oil separator.

The third method to avoid the liquid shock and noise problems of the refrigerator: tighten the screws, ensure that the machine feet and brackets are in compliance with the requirements, and avoid the increase in noise and vibration due to these reasons.

The fourth method to avoid the liquid shock and noise problems of the refrigerator: install it on a flat ground and install it according to the regulations!

Needless to say, when installing the refrigerator, it must be done well.

The fifth method to avoid liquid shock and noise problems of the refrigerator: avoid preventing various items on the main body of the refrigerator, and ensure air circulation and ventilation and heat dissipation, and avoid noise and vibration problems caused by poor heat dissipation, especially for air-cooled refrigerators. .
