The invention relates to a
data center equipment
type selection method based on electrical and heating ventilation load linkage, and belongs to the technical field of
data center infrastructure design. The
model selection method comprises the steps of setting basic data, obtaining the number of
machine rooms and the number of IT devices in a single
machine room, obtaining the total power of the IT devices, setting an energy efficiency index set value, obtaining the project
power consumption scale, obtaining the total
cooling load, selecting models of air conditioners at the
tail ends of the
machine rooms and substations, selecting models of water chilling units, selecting models of heat exchangers, selecting models of cooling water pumps and
chilled water pumps and selecting models of cooling towers. And obtaining the total power of the air conditioner, obtaining an energy efficiency index accounting value, and carrying out PUE
verification. According to the method, through closed-loop iteration of
electrical load-heating and ventilation load-PUE,
model selection and quantity selection of all key equipment are completed at a time; professional splitting, repeated adjustment and modification and capacity redundancy caused by traditional serial design are avoided, the design period is remarkably shortened, and initial investment is reduced.
