Adjustment of LNG cryogenic tank refrigerant ratio

Based on your description, to increase the cooling capacity, you can try the following methods to adjust the refrigerant ratio in the LNG cryogenic tank: 1. Adjust the exhaust temperature of the refrigerant compressor: Check whether the exhaust temperature of the cryogenic tank’s refrigerant compressor is too high, as a high temperature may lead to a reduced cooling effect. The exhaust temperature can be reduced by cleaning or replacing the compressor intake filter, as well as by increasing ventilation in the condenser. 2. Adjust the cleanliness of the condenser: Scaling can hinder heat transfer efficiency and affect cooling performance. The condenser can be cleaned and inspected regularly to keep its surface clean and improve heat transfer efficiency. 3. Check the refrigerant charge: Verify that the amount of refrigerant filled meets the design requirements; if it is insufficient, add more refrigerant to ensure the system is fully filled with it. 4. Adjust the design parameters of the evaporator: Depending on the actual conditions, it is possible to adjust the design parameters of the evaporator, such as increasing its heat transfer area or changing its inlet temperature, in order to enhance the cooling capacity. 5. Check the type of refrigerant: Depending on the cooling requirements and actual conditions, it may be necessary to replace the refrigerant. When selecting a new refrigerant, factors such as its cooling performance, environmental friendliness, and compatibility with supporting equipment need to be considered. It should be noted that when adjusting the refrigerant ratio in the LNG cryogenic tank, it is recommended to seek the help of professional engineers to ensure safe and reliable operation. .
