In today's rapid development of the digital economy, data centers, as the core of computing infrastructure, have attracted much attention to their energy consumption. According to statistics, air conditioning systems account for more than 40% of the total energy consumption of data centers, and how to improve cooling efficiency and reduce PUE (energy use efficiency) has become a key challenge in the industry.

With its innovative advantages such as all-EC frequency conversion technology, near-end refrigeration design, and natural cooling source utilization, Haiwu CRA has become an ideal temperature control solution for small and medium-sized data centers, modular computer rooms, and high-heat density cabinets, helping enterprises achieve efficient, low-carbon, and sustainable data center operations.

 Core product advantages: precise refrigeration, high efficiency and energy saving

1. Close to the heat source, precise air supply

• It adopts the inter-column level proximal refrigeration design, which is directly installed in the cabinet row to shorten the cold air path and reduce the loss of cold capacity.
• Precise control of server sensible heat avoids the mixing of hot and cold of traditional room-level air conditioners and improves cooling efficiency.

2. Full EC frequency conversion technology, intelligent adjustment

• The key components are made of internationally renowned brands to ensure high reliability.
• The full EC inverter compressor + fan automatically adjusts the cooling capacity and air volume according to the load, and the energy saving effect is remarkable.

3. Efficient heat exchange design to improve energy efficiency

• The "full-cabinet one-line/U-shaped" evaporator increases the heat exchange area, reduces wind resistance, and improves refrigeration efficiency.
• "V" type condenser + three-sided return air design optimizes heat dissipation performance and adapts to high return air temperature scenarios.

 4. Intelligent O&M, flexible expansion

• The pull-out design of the electronic control box supports front + back maintenance, reducing the difficulty of operation and maintenance.
• Group control networking function, intelligent collaboration of multiple air conditioners, and adjustment of operation strategies as needed.
• Optional power metering module monitors energy consumption in real time and helps refined management.

Applicable scenarios: Covering the needs of data centers in multiple industries

Haiwu CRA inter-column air-cooled precision air conditioners are widely used in:

✔ Small and medium-sized data centers – provide efficient cooling and reduce PUE

✔ Modular data center – flexible adaptation and rapid deployment

✔ High heat density computer rooms (such as AI servers and GPU clusters) - precise heat dissipation to ensure stable operation of equipment

 Typical Industry Applications:

• Internet & Cloud Computing: Meet the cooling needs of high-density servers
• Carrier IDC: Reduces operating costs and complies with green data center standards
• Financial securities: ensure the stable operation of the core trading system
• Government & Enterprise Data Centers: Energy conservation and consumption reduction, responding to the "dual carbon" policy

Social value: green refrigeration and empowering the digital economy

1. Low-carbon and energy-saving, in response to national policies

• The fluorine pump natural cooling technology is used to make full use of the natural cooling source in a low temperature environment, reduce the operating time of the compressor, and save more than 30% of energy.
• In line with the industry trend of "wind in and water retreat", reduce water consumption, and meet the standards of green data center construction.

2. Improve the energy efficiency of computing power infrastructure

• Through near-end cooling + intelligent frequency conversion, it significantly reduces the PUE of the data center and helps enterprises pass the "Data Center Energy Efficiency Limit Value and Energy Efficiency Level" (GB 40879) certification.
• Support the construction of a national integrated computing power network, and provide efficient temperature control solutions for East Data and West Computing and AI Computing Power Centers.

3. Promote the sustainable development of the digital economy

• Ensure high reliability and low latency in data centers to meet the needs of emerging technologies such as 5G, AI, and edge computing.
• Help enterprises achieve green transformation and improve ESG (environmental, social, governance) ratings.
