An increasing number of data centers have been developed in line with the progress of digitalization in recent years. It is an urgent issue to reduce the power consumption of non-IT facilities and significantly improve power usage effectiveness (PUE) in the trend toward carbon neutrality. As such, Mitsubishi Heavy Industries, Ltd. (MHI) participated in the development of a containerized data center with an immersion cooling system that achieves compactness and low PUE for use in multi-access edge computing (MEC) and installed it in Yokohama Hardtech Hub. As a result, PUE of less than 1.07 was achieved. Moving forward, we will propose a system that optimizes the entire system, including a hyperscale data center, and progress with the development to meet the needs of our customers.
