WCT Series Integrated Refrigerant Unit integrates the application of natural air and greatly reduces the overall energy consumption of the unit by using fluorine pump liquid natural cooling technology. 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 to the maximum, 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 reduces the air leakage rate of the unit and then improves the reliability of on-site operation. With cooling capacity covering 150 kW to 250 kW, the unit is green, low-carbon, energy-saving, efficient, flexible combination, and widely used in green data centers.
Core Value
Air-cooled system design instead of evaporative cooling:
• No need for water consumption during operation, resulting in no water demand or consumption
• Suitable for water shortage areas
• Saving water costs as well as water treatment and maintenance costs
Energy-efficient system design:
• High energy efficiency ratio (EER), and annual average PUE as low as 1.1 in cold regions, saving electricity and distribution costs
• Overall heat insulation, reducing the loss of cooling capacity
• Smooth airflow, and high heat exchange efficiency
Prefabrication:
• All-in-one structure design against air and water leakage
• Integrated evaporator-condenser design, which avoids the impact of long pipes and high drop on the performance of the split type product design when deploying
• Engineered product, improving the reliability and stability of the unit
Extreme silence:
• The fans adopt redundant hot standby design
• The heat exchanger is designed with dual coils in one single system, which has a large windward area, low wind speed, and can reduce the overall power consumption and noise of the unit
Application Scenarios
• Innovative green data center
The unit is integrated with the building structure of the server room, relying on the enclosed cold and hot aisles to reduce the energy consumption.
• Renovated energy-saving data center
The unit is integrated with the building structure of the server room, relying on the natural cool sources outdoors to dissipate the heat out of the server room.
