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.
