If you find that the refrigerator is running out of oil, it basically has a lot to do with its structure. There are some refrigerators on the market that are manufactured in this way, that is, the original refrigerating oil and refrigerant are mixed. Because the density of the refrigerating oil and the refrigerant is different, that is, the weight is different, an oil separator can be used at this time. The freezing oil of the unit is separated from the refrigerant, and then the refrigerant is returned to the compressor through the flooded evaporator. This new type of refrigeration effect is quite good, but the easy failure is that the oil may run out, so why does it happen? How about running oil? Follow the editor of China Horizontal plate freezer on sales for a simple understanding!
We just explained this principle to you, so we will analyze the problem and solve the problem from the principle. When the cooling water temperature is low, the overheating degree of the startup is not high, and then due to the incomplete separation of the refrigerant, a mixture of refrigerant oil and refrigerant will appear, and they will enter the heat exchanger together, which will make the contentment low pressure and even low In severe cases, the expansion valve may be blocked, so that the refrigerator cannot be started. What should we do at this time?
If it is found that the classified oil level is lowering, the unit should be adjusted to manual control mode immediately, so that the load limit of the compressor can limit its energy to 50%, so that the condensing pressure will increase and the low pressure alarm value of the unit will be reduced to the allowable value. Within the scope, this can try to ensure that the unit is in a state that will not stop and can still be started. If we carry out the above operations and find that the oil level of the refrigerator is still very low, and the pressure of the evaporator is also very low, we need to consider whether the oil is Not all have run into the evaporator. At this time, we can see if there is a large amount of white foam rolling in the evaporator is the liquid crystal. If there is, it means that the oil is in the evaporator.
The above is the relevant knowledge of the analysis of the principle of oil running in refrigerators introduced by the editor of China Horizontal plate freezer on sales. I hope you can learn more.
