✦ AI Summary
Kakao said on the 22nd that it applied the heat management methods it had built up at its own data center to a leased data center. It improved the cooling system operations at a data center in Hanam, Gyeonggi Province, that is operated by LG CNS. As a result, the cooling power cost at the leased data center fell by about 23% from a year earlier.
Kakao said on the 22nd that it applied the heat management methods it had built up at its own data center to a leased data center. The company said it improved the cooling system operations at a data center in Hanam, Gyeonggi Province, that is operated by LG CNS. Kakao Data Center Ansan is located on the Hanyang University ERICA campus in Ansan, Gyeonggi Province.
Kakao pursued efficiency without replacing or adding new cooling equipment. The focus of the savings was on optimizing the operating method of the existing cooling systems. To that end, it adjusted the cooling temperature in the computer room and the chilled water temperature of the chiller.
As a result, the cooling power cost at the leased data center fell by about 23% from a year earlier. Kakao said the comparison with the same period a year ago reflected the impact of server usage and outdoor conditions.
During operations, Kakao adjusted temperature conditions based on actual operating data and on-site conditions. LG CNS changed the operating conditions of major cooling equipment such as precision air conditioners (FWU) and chillers. LG CNS also checked stability step by step.
An AI agent developed by LG CNS supported the process in some computer rooms. The AI agent was responsible for analyzing the computer room environment and equipment operation data in real time, controlling the cooling equipment, and searching for the proper operating values. However, a Kakao official said that, as a factor behind the results, there was a difference in human operations capability rather than in AI capability.
The approach applied in Hanam was based on the operational experience of Kakao Data Center Ansan. Kakao Data Center Ansan is Kakao's first in-house data center. In Ansan, Kakao improved cooling and air-conditioning operations and also improved the efficiency of its power facilities, cutting greenhouse gas emissions by 4,753 tCO2eq annually as a result. The reduction effect has also been verified by a third party.
However, in Hanam, because it is a leased data center, consultation with the facility operator was necessary. In addition, due to the constraints of a leased data center, it was difficult for Kakao to change operating methods on its own. Accordingly, in Hanam, Kakao proposed energy-saving measures, while the operator, LG CNS, took charge of adjusting the on-site equipment operating methods.
The company said that expanding the approach to other leased data centers would require consultation with each operator. Because operating operators and equipment environments differ from center to center, the specific expansion targets have not been decided, and the specific schedule has also not been decided, it said.
A Kakao official said the company confirmed the potential to improve energy efficiency based on operating data even in an environment where equipment replacement is limited. The official added that Kakao plans to continue expanding eco-friendly data center operations based on its technological capabilities and on-site collaboration.
