High Efficiency Fan In Row Air Cooling Units For High Heat Density Data Centers

Electronically Commutated Compressor
♦R410A
♦Compressor speed is infinitely variable dependent on the heat load
♦Energy saving under partial-load mode, improving energy efficiency
♦Significant reduce the start/stop frequency of the compressor
♦Improve the system reliability

EC Fan
♦Saving 20~30% energy compared to traditional AC motor
♦Soft-startup function, low startup current
♦Adjust rotary speed automatically according to cooling requirements and airflow pressure, and provide airflow as required
♦N+1 redundancy configuration of fans, ensure the airflow in case of any fan fault
♦Easy-maintenance designed

Electronic Expansion Valve
♦Adjust the throttle of valve smoothly and combine with the EC compressor to save the energy
♦Wide range of operations, which can help reduce the superheat degree and improve the EER
♦Realize cooling capacity and heat load precise matching
♦Quick response, realize the precise cooling

• It can be cooled close to the heat source, the air flow path is short, and the cooling capacity loss is small;
• Adapt to high return air temperature, high matching degree with the output air temperature of equipment with large heat generation;
• Ultra-high energy efficiency ratio, energy saving, and low operating cost;
• Ultra-high sensible heat ratio, will not cause excessive dehumidification;
• High reliability, long life design: 24 hours 365 days uninterrupted operation design, the design life is 10 years;
• Multiple high-efficiency backward-inclined centrifugal direct-connected fans, air volume redundancy design, each fan is designed to operate at the best efficiency point under standard working conditions;
