What Happens If the Screw Chiller Lacks Refrigerant

Jul. 01, 2020

The ice water and cooling work of the screw chiller are based on refrigerant. Without refrigerant, screw chillers have no refrigeration function. When you find that the screw chiller reduces the cooling effect of the equipment and reduces the cooling capacity, it is likely that the refrigerant is insufficient. So, what happens if the screw chiller lacks refrigerant?

What is the performance of screw refrigerators lacking refrigerant? The most basic performance is: the cooling capacity is reduced, and the cooling effect is reduced. The lack of refrigerant for screw chillers also includes:

Judging from the load performance of the compressor: When the compressor load of the screw chiller suddenly increases, sometimes overload protection will occur, and it is basically judged that there is no problem with the compressor or insufficient refrigerant. Due to insufficient refrigerant in the working chamber of the compressor, the compressor will automatically increase the working load by increasing the compression effect of a small amount of refrigerant to a normal amount of refrigerant.

Observation window: You can directly observe whether the refrigerant is missing. It is generally believed that any refrigerant loss can be observed through the observation window. Of course, the foam roller can only be observed when the system is running, but the foam is not necessarily refrigerant, or the system is not smooth. Please note this for other reasons.

The cause of insufficient refrigerant may be normal consumption, but on the other hand, it may also be abnormal consumption: the most common type of abnormal consumption is leakage. Refrigerant leakage is a common problem in screw chillers, and it is also one of the main causes of insufficient refrigerant and insufficient refrigerant in screw chillers.
