Abstract

The purpose of this study is to clarify the practicability of the electrical loss component (ELC) index proposed by ASHRAE standard 90.4 during the design phase of data centers in South Korea. For this purpose, we derived the main design components required for the calculation of ELC by reviewing the design document of electrical equipment and was conducted by the ELC method for two domestic data centers. The results were as follows : (1) The energy performance information in the design document was insufficient to calculate the ELC of the incoming electrical service segment at the front of the UPS. (2) The ELC value was affected by the efficiency of the voltage conversion rather than the distribution loss. (3) The effect of the load rating was underestimated when calculating the ELC based on the test report suggested by the manufacture. (4) If the actual energy efficiency of the equipment is secured in the design phase, the efficient design of power supply systems based on the ELC will be possible in the future.
