Research on the application of district cooling system in cloud computing center in cold climate: taking Inner mongolia as an example

摘要

In recent years, the cloud computing center has developed rapidly all over the world, the contradiction between its high energy consumption and the present situation of tension energy supply increasingly stand out. One of the most effective cards to reduce the electricity consumption of cloud computing center and decrease operating cost is reducing the power consumption of air-conditioner. In this project, on the basis of heat supply capacity in thermal power plants and the cold demand of users in terminal cloud computing center, LiBr absorption chiller utilizing gas and electric centrifugal refrigerator were adopted, and the energy was electricity power from thermal power plant and waste heat steam power generation. In addition, in consideration of high reliability about cold source of data center, the standby energy was natural gas, and LiBr absorption chiller utilizing gas was adopted. The guaranteeing design of equipment, energy, water supply and drainage, and cooling network satisfied the request of cooling safety for users. Construction of this district functional item brought out economic benefits such as the reduce of operating cost, plant room, placing cooling tower and maintenance attendance cost, social benefits such as the increase of overall energy utilization degree, the decrease of heat island effect and carbon dioxide.
