Application analysis of various air conditioning formsin a data center in Guiyang

This paper takes a data center in Guiyang as the research carrier. Through the analysis of the project overview, climate conditions, resource conditions, air conditioning principle and technical scheme,the number of cabinets, energy conservation and economic indicators of each air conditioning scheme are explored and compared. The results show that the construction investment of the maglev evaporative phase change cooling air conditioning scheme is high, but it can greatly improve the number of cabinets and the project income. This air conditioning system consumes less electricity throughout the year, but the water consumption is large. The indirect evaporative cooling air conditioning scheme has the best energy conservation, but the number of cabinets is the least, the unit power consumption cost is high, and the profit rate is low. The water-cooled chilled water air conditioning scheme has poor energy conservation and less number of cabinets, but the construction investment is low.
