Indirect External Air Cooling Type Energy-Saving Hybrid Air Conditioner for Data Centers, 'F-COOL NEO'

摘要

To improve the energy efficiency of air conditioners in data centers, in which heat generation is dramatically increasing due to improved performance and higher-density of servers, systems that make use of outside air cold, which is natural energy, are being adopted. Fuji Electric has developed a hybrid air conditioner "F-COOL NEO" combining indirect external air cooling, which is less susceptible to the effect of dust and corrosive substances contained in external air, and vapor compression refrigeration cooling. F-COOL NEO automatically controls the operation ratio of the two types of cooling according to external air temperature and a cooling load. As a result of evaluation, it has been verified that high efficiency can be attained of the amount of power consumption throughout the year approximately 1/3 that of general air conditioners.
