since 2014, Accessen has provided heat exchange solutions on demand for dozens of data centers in Xinjiang Karamay, Jiangsu Yancheng, Guangdong Shenzhen, Zhejiang Huzhou, Hunan Yongzhou, Sichuan Luzhou, Jilin Changchun, Yunnan Yuxi and Tianjin. Nearly 40 sets of heat exchange equipment with stable performance and fast and efficient service have won the trust of customers. Huawei Yuxi E-cloud computing data was in the Jiulong electronic information industrial park of Yuxi. As Huawei important national E-cloud services network, the data center is set up with 1,000 E-cloud computing cabinets, which can provide 10,000 E-cloud servers, 80PT storage, and 20,000 E-cloud computing services. It could provide E-cloud service for nearly 50 enterprises, jointly create the Yuxi model of "Internet + Education" and becoming a model of educational informatization reform in Yunnan and even the whole country.

In the technical design planning, Huawei Yuxi E-cloud computing data center will take advantage of the free cooling system application due to the unique climate conditions in Yunnan (low outdoor temperature in spring, autumn, winter seasons). Under the condition of mechanical refrigeration units closed, cool the data center machine room through the plate heat exchanger and cooling tower to make a cold source, thereby reduces the energy consumption of the data center. The free cooling source system is composed of a cooling tower, plate heat exchanger, chiller, circulating pump, air conditioning terminal, etc. The plate heat exchanger and related switch valve group are installed based on the original cooling water system. In high-temperature weather, chillers are used for mechanical refrigeration. In low-temperature season, low-temperature cooling water generated by the cooling tower is heat exchanged with high-temperature chilled water. In transition season, low-temperature cooling water and high-temperature chilled water are pre-cooled before entering the chillers. So we can reduce the load and running time of chiller, also reduced the energy consumption. Although waterside in a natural cooling system is relatively complex, it has become the most recognized air conditioning system scheme in China's current data center project design with the increasingly mature process and remarkable effect in data center application. As indispensable equipment in the free cooling system, the plate heat exchanger plays an intermediary role in energy exchange in the whole system. During the technical discussion period, Huawei finally selects Access as a heat exchange equipment partner after consideration of performance, effect, services, performance, price, and other comprehensive factors. Accessen has rich experience in the application of energy saving in the data room. Rich plate type provides a better choice for the realization of various air-conditioning system heat exchange and energy saving. Accessen efficient plate heat exchanger can achieve less than 1 ℃ logarithmic mean temperature difference in heat transfer, fully use the free cooling source, increase thermal efficiency, reduces the engine running cost. Advanced structural design makes the later maintenance more convenient.
