Abstract

It is currently estimated that with the increasing numbers of IT equipment, the amount of information data used by society will reach 200 times the present volume by 2025. Under such circumstances, there is an urgent requirement for cooling systems in server rooms with high density servers and compatibility with faster and larger servers along with high environmental efficiency. This survey carried out an experiment in which energy performance measurements with variance of outside air taken into the server room in a real size server room were taken. The results show that the cooling load of air conditioners could be approximately 90 percent less than that of the conventional air conditioning system for server rooms and that the overall energy consumption and COP are increased by 18 percent and 24 percent of the maximum respectively, compared to those of the conventional systems under maximum heat load conditions.
