Green energy saving practice in Unicom Harbin Cloud Data Center

Based on the superior natural climatic condition and the natural cooling technology, Unicom Harbin Cloud Data Center uses the operation mode of plate heat exchanger and dry cooler to provide cold source for the data room. The operation results show that in the initial stage of production, the low-load operation mode saves electricity by 29%. After reaching the design load, the operation mode is expected to save electricity 5.78 million kWh per year, and the power saving rate can reach 31%. The water saving is obvious, and the energy saving benefit is good.
