1) No cooling tower, circulating water pump, water pipeline, etc. are needed. The unit has compact structure, small floor area, convenient on-site installation, space saving and cost reduction

2) A cooling tower is not needed, which reduces the project investment cost, and can save water by more than 50% compared with a water-cooled unit using a cooling tower

3) ethylene glycol is used as the coolant, which has large specific heat, large cooling capacity with the same mass and good heat transfer, and the temperature of the cooled object is easy to keep stable

4) all kinds of equipment of the refrigeration device are arranged together to facilitate operation and management

5) Using the water film evaporation phase change cooling mode, there is no need for a cooling water tower, and the phenomenon of "flying water" in the cooling water tower is completely eliminated

6) Cold energy can be sent to a place far away from the refrigeration system, which is convenient for distribution and control of cold energy

7) Reduce the total volume of refrigerant piping system, thus reducing the refrigerant charge and leakage in operation
