Aquatic Processing Flake Ice Machine Factory Tells You How To Make The Cold Storage Temperature Drop?

1. Aquatic Processing Flake Ice Machine Factory tells you the cold storage throttle valve is improperly adjusted or blocked, and the refrigerant flow rate is too large or too small. If the cold storage throttle valve is improperly adjusted or blocked, it will directly affect the refrigerant flow entering the evaporator.

2. The refrigerant quantity in the cold storage system is insufficient and the refrigeration capacity is insufficient. There are two main reasons for the shortage of refrigerant in the cold storage. First, the refrigerant charge is insufficient. In this case, it is only necessary to fill in a sufficient amount of refrigerant. Another reason is that the system refrigerant leaks more. In case of such a situation, the leak point should be found first, and the connection points of each pipeline and valve should be checked. After the leak is repaired, a sufficient amount of refrigerant is charged.

3, the compressor efficiency is low, the cooling capacity can not meet the warehouse load requirements. Due to the long-term operation of the compressor, the components such as the cylinder liner and the piston ring are seriously worn, the clearance is increased, the sealing performance is reduced, the gas transmission coefficient of the compressor is also reduced, and the cooling capacity is reduced.

Therefore, in daily operation and maintenance, attention should be paid to timely clearing the external oil in the evaporator heat transfer tube and discharging the air in the evaporator of the cold storage to improve the heat transfer efficiency of the evaporator. Improper adjustment or blockage of the throttle valve will directly affect the flow of refrigerant into the evaporator.
