In the precision air conditioning system of data centers, Tianlai Energy-Efficiency centrifugal atomizers are deployed on the air intake side of outdoor unit condensers. Adopting high-speed centrifugal technology, the equipment breaks water into ultra-fine droplets with a diameter of ≤80 microns (only 1/500 of the volume of original water droplets), boosting the evaporation speed by more than 300 times. The fog droplets rapidly vaporize and absorb heat in the air intake area, reducing the average air inlet temperature of the condenser by 10.5°C. This significantly cuts down the condensing temperature and pressure, lowers the exhaust resistance and operating power consumption of the compressor, and directly optimizes the PUE of data centers. Meanwhile, the reduced condensing pressure extends the service life of the compressor and prevents high-temperature shutdowns. As a superimposed energy-saving solution, it can be quickly deployed without replacing the existing main air conditioning units, making it especially suitable for low-cost renovation of existing computer rooms. Faced with the dual pressure of high heat density and stringent PUE indicators in modern data centers, centrifugal atomization technology has become an indispensable core energy-saving method to ensure safe equipment operation and reduce operational energy consumption, thanks to its remarkable cooling effect and ultra-low renovation cost.
Targeting the core pain points of precision air conditioners in data centers — excessive wind resistance, scaling, water leakage, and inaccurate temperature control — the centrifugal atomizer delivers a perfect solution with superior performance. Firstly, in terms of atomization performance, it converts water into micron-level fog droplets and achieves uniform coverage of parallel fog within a diameter of 1.6 meters. The fog distribution is perfectly parallel to the heat exchange fins, completely avoiding local overcooling, water dripping and scaling. It ensures uniform and efficient condensing heat exchange without increasing wind resistance. Secondly, in terms of energy saving and intelligent control, the atomizer features powerful intelligent adaptation capabilities. It supports intelligent speed regulation and 485 communication control, enabling real-time monitoring of air conditioner load and dynamic adjustment of spray volume (with a flow rate of only 6-60L/H) to realize true on-demand cooling. It achieves prominent evaporative cooling with extremely low water consumption and eliminates energy waste caused by excessive cooling. In addition, in terms of safety and operation and maintenance, the low-pressure water circuit design completely eliminates the risk of computer room water flooding caused by high-pressure pump pipe bursts. With flexible water quality requirements, it requires minimal daily maintenance. Integrating efficient cooling, ultimate safety and low operation and maintenance costs, the Tianlai Energy-Efficiency centrifugal atomizer serves as an ideal and indispensable product for energy-saving renovation of outdoor units of precision air conditioners in data centers.
