Entry Description
1.What are your product's/solution's key distinguishing features
ZTE Indirect Evaporative Cooling(IEC) solution brings in natural cold source to cool data center, reducing the demand for traditional air conditioner. Therefore, IEC solution achieve the goal of reducing carbon emissions by saving electricity. In the dry and cold regions of China, 70% electricity consumption can be saved.The unit capacity of our products is 130kW and 260kW, it supports dual-machine parallel operating, can be deployed in phases, and supports flexible expansion. Our product can be installed not only in data centers but also in some core rooms in the operator network. It only takes 3 man-days to install one unit which is very convenient and a big saving for manpower cost. At present, the IEC air conditioner have been deployed in China. ZTE helped Baidu to deploy more than 190 IEC units in its cloud data center , and helped Tencent to deploy 36 IEC units in its T-Block project. On the operator side, China Mobile has begun to trial the solution, and will follow up in its data center. The other two major operators in China have expressed strong interest in the application of IEC air conditioners. In the next few years, IEC air conditioners will achieve large-scale applications in the world.

2.What, exactly, is novel about the product / process or innovation?
The basic principle of IEC technology is to humidify the outside air to reduce its temperature, and then exchange heat between the hot air inside the data center and the humidified cold air through an air to air heat exchanger, thereby achieving cooling of the data center without operating traditional air conditioners.

3.How does the product or process break with conventional ideas or processes in its field?
IEC solution extend the natural resource cooling time as maximum as possible compared to conventional IDC cooling solution, it supports dual-machine parallel operating, can be deployed in phases, and supports flexible expansion. Our product can be installed not only in data centers but also in some core rooms in the operator network. It only takes 3 man-days to install one unit which is very convenient and a big saving for manpower cost.

4.How does it go beyond marginal improvements on something that already exists?
Air-to-air heat exchangers we adopted have the highest certification in the industry, and its efficiency is upto 70% which is higher than most competitor. In the northwest city Zhangbei in China, the minimun partial PUE is 1.03 which is lowest on the market. The host segment consists of three layers of independent functional modules that are assembled quickly. A reliable open architecture PLC is used to support customer customization. The solution is highly automated, and high pressure water gun and maintenance ladder is built-in for easy maintenance. Unique double-layer counterflow spray humidification is adopted, the humidification evaporation efficiency is upto 85% which is highest on the market.

5.How do customers benefit from the product/ process or in
IEC solution has been implemented in Shenzhen. The climate in Shenzhen is hot and humid, not the best geographical location for IEC application, but even so, significant energy savings have been achieved, and the the air conditioner operation time is reduced by 38% and the data center cooling load factor CLF(cooling power consumption/IT power consumption) is not more than 0.25. IEC Technology has also been deployed in the Tencent Western Laboratory Project, located in Guiyang, Guizhou, China. The climate there is dry and very suitable for the IEC application. After the authoritative testing by the Ministry of Industry and Information Technology of China, the overall Power Usage Effectiveness (PUE) of the data center is only 1.09, and the energy saving effect is remarkable compared to the traditional data center.
