What causes the low suction pressure of the refrigeration unit?
In the pharmaceutical, food and other industries, refrigeration units are common equipment, providing reliable protection for various low-temperature environments such as pharmaceuticals.
In recent years, with the continuous development of my country's pharmaceutical industry and the continuous improvement of production, logistics and transportation requirements, the refrigeration unit market has ushered in a good room for development, and through continuous improvement and upgrading, to provide pharmaceutical companies with higher quality refrigeration units equipment.
However, in the process of using the refrigeration unit, even if the user purchases a regular brand, there are no major faults, but small faults often occur from time to time. Therefore, the user needs to understand the common faults of the equipment and the corresponding solutions to ensure that the equipment can continue to operate .
It is understood that in the process of using refrigeration units, many users often find that the cooling effect is suddenly not as good as before, or there is no cooling. What is going on?
According to the industry, the poor cooling of the refrigeration unit means that the suction pressure of the equipment is too low.
So, what is the reason for the low suction pressure of the refrigeration unit? How should the user solve it?
In this regard, some factory technicians said that in fact, there are many reasons for the low suction pressure of the refrigeration unit, including the refrigerant filter clogging the valve, not fully opening, insufficient refrigerant charging, etc. The following briefly introduces common faults and their Solution.
Fault one
The refrigerant filter is clogged.
The refrigerant filter has an important filtering function and should be kept unblocked. If clogging occurs, the filter needs to be cleaned or replaced regularly.
Fault two
Improper adjustment or malfunction of the expansion valve.
If this phenomenon occurs, it is recommended to adjust the correct or troubleshoot immediately, and replace it if necessary.
Fault three
The condenser refrigerant liquid outlet valve is not fully opened.
It is reported that if the refrigerant liquid outlet valve of the condenser is not safely opened, the refrigeration unit will produce a situation where the suction pressure is too low. At this time, the valve should be fully opened.
Fault four
The amount of water passing through the evaporator is insufficient.
In this case, the cooling capacity will also decrease and the cooling effect will be poor. The user should check the water pump and water valve in time.
Fault five
Excess lubricating oil circulates in the chiller refrigeration system.
If you find that there is a lot of lubricating oil in the refrigeration system, you should find out the reason at this time and reduce it to an appropriate value.
Fault six
When the inlet water temperature of the evaporator is too low, the cooling effect is not good.
In this case, the set value of the inlet water temperature should be increased.
In addition, technicians said that since the cooling water of the refrigeration unit is an open circulation loop, the tap water generally used is recycled through the cooling tower. When the content of calcium and magnesium salts in the water is large, it is easy to decompose and deposit on the cooling water pipe. The formation of scale, thereby affecting heat transfer.
"If the scale is too thick, the flow cross-section of the cooling water will be reduced, the amount of water will decrease, and the condensation pressure will increase."
The technicians suggest that when users find that the water quality of the cooling water used by the refrigeration unit is poor, it is recommended to make a regular cleaning plan to clean the cooling water pipe at least once a year to remove the scale and other dirt in the pipe to prevent the pipe Blockage of the road.
Eliminate the above six types of failures, if the user still can not find the cause, you can contact the manufacturer for maintenance services, which is also the important significance of the existence of regular refrigeration unit equipment manufacturers.
