How i-Row Achieves High Energy Efficiency
●Close to the heat source, the return air temperature and evaporation pressure are improved, and the refrigeration efficiency is improved
●The system design of the unit adopts computer-aided fluid dynamics (CFD) calculations to ensure the optimal distribution of airflow within the unit and between racks
●DC variable frequency EC compressor can adapt to rapid changes in server temperature, reduce frequent opening and closing of the compressor, and also improve system reliability
●Advanced EVO controller, controlling air volume and cooling output as needed, combined with EC fan and DC variable frequency EC compressor to achieve the best effect and minimum
●Energy consumption; Multiple control algorithms can be used to calculate the highest and average temperatures, which can ensure effective cooling and effectively reduce the total temperature
●Physical energy consumption
i-Row air-cooled condenser
●Stepless speed regulation owl type fan control
●Extremely low maintenance requirements, suitable for various climatic conditions
