In the development of modern information, data center undertakes extremely important central nervous system, with a few notable features in this system: 1, the sensible heat of a very high proportion, about 0.95~0.99; 2, precision air conditioning with high precision and sensitive control system based on microprocessor, can change the external environment quickly in response, so as to ensure the environmental change range of setting value required to keep stable in the environment; 3, computer room precision air conditioning usually adopts high efficiency filters, the dust in the air to a minimum; 4, the design of air-conditioning in a full 8760 hours operation design, components have redundant function, it will greatly improve the reliability, reduce the cost of operation and maintenance. Therefore, based on such conditions, the refrigeration system in the engine room area should take full account of the above factors.
Worsley demands to the current data center equipment power density, reliability and flexibility based on the actual air conditioning system are not the same, the data room chiller application has the following features:
The advanced modular configuration, meet the requirements in the long term, in line with the development trend of IT;
The reliability of system redundancy, multi pipeline routing, considering from the cold source, and at the end of the pipeline configuration;
The flexibility of modular design, system flexibility and scalability;
The function of the space design and functional areas set up in line with the service process, and flexible combination;
The service: it is easy to maintain, update, monitoring and service facilities to meet the;
The economy: green data center energy saving, green environmental protection, energy saving, automatic operation control and low PUE;
The energy recovery: through system integration, to achieve the data room heat into heating and hot water production and energy recovery system for city winter heating, hot water supply, it becomes possible to provide
