Highlights and values of Inspur scheme

Energy Conservation Special Chapter

An important indicator of measuring the energy consumption of data center is PUEPower Usage Effectiveness. PUE is an energy ratio of all energy consumed in data center to energy used for IT load. That is to say PUE=energy consumption of total equipments in data center/ energy consumption of IT equipments. Currently, PUE of domestic data center is generally about 2.0, and the design aim of this product is PUE1.6.

High-efficiency heat preservation measures: interior of container is laid with 50mm thickness color-coated steel sandwich board. The thermal insulation material inside color-coated steel sandwich board is XPS Polystyrene with heat transfer coefficient 0.003W/ (m,K), and it effectively prevents solar radiation from entering into interior of container while prevents the external flow of refrigeration capacity. The pipeline connecting outdoor unit of air conditioning and end of refrigeration is wrapped with heat preservation cotton, it prevents heat transfer between refrigerant and outside environment and avoids refrigeration capacity waste.

Hot and cold channel separation: the cold channel and hot channel is separated through reasonable layouts, thus it can avoid refrigeration capacity waste caused by cold and hot flow mix.

High-efficiency precision air conditioning: adopting high-efficiency precision air conditioning can get larger refrigeration capacity in the same power consumption condition. It can automatically regulates refrigeration capacity and directly save electric energy.

Precise air supply: precision air conditioning adopts horizontal circulating air supply mode, making cold air enter into IT equipment in the shortest distance and avoiding the loss of air flow. At the same time, horizontal circulating air supply mode solves the problem of large temperature difference in the top and bottom of IT cabinet caused by under inlet air and upper return air. It realizes the high density application of rack.

Special Chapter of Reliability

Waterproof design: since the founding of data center, water damage has been always upsetting people. The water collector installed in the bottom of precision air conditioning can draw the condensate water that may arise to the outlet appointed by customer through drain pipe.

Fire prevention design: in accordance with article 3.1.4 of GB50222-95 Fire Protection Standard of Building Internal Decoration and Design, large and medium-sized electronic computer room, master control room, telephone exchange room and other rooms that place special equipment,whose ceilings and walls should adopt grade A decoration materials, and ground and other decoration should adopt materials that no less than grade B1. All decoration materials used in this project can meet requirements. In the meantime, monitoring and fire protection system are linkages. Set up fire alarm system, founding fire alarm timely.
