SCF Integrated FP Unit integrates the application of natural air and greatly reduces the overall energy consumption of the unit by using natural cooling technology with fluorine pump liquid. The unit integrates three cooling modes: full variable frequency fluorine pump natural cooling mode, variable frequency fluorine pump + variable frequency compressor hybrid cooling mode, and full variable frequency compressor cooling mode. The overall unit adopts a V-type condenser and an A-type evaporator, increasing the overall heat exchange area, extending the unit's natural cooling operation time, reducing the system pressure ratio in both pump and compressor modes, and reducing the rated temperature point for full cooling capacity of pump operation. The overall unit adopts an integrated design, which can reduce the air leakage rate and then improve the reliability of on-site operation. With cooling capacity covering 150 kW to 250 kW, the unit is green, low-carbon, energy-efficient, flexible combination, and widely used in green data centers.
