Kakao Cuts Cooling Power Costs at Rented Data Center by 23% With AI
TECHWORLD ·
✦ AI Summary
Kakao said on the 22nd that it had improved the cooling system operation method at a data center in Hanam, Gyeonggi Province, that is operated by LG CNS under contract.
Without replacing or expanding equipment, it adjusted the cooling temperature in the server rooms and the chilled-water temperature of the chiller, and applied LG CNS's AI agent to some server rooms.
Kakao said cooling power costs fell by about 23% on a comparison basis that reflects server usage and outside air conditions, and that it maintained service stability despite extreme heat and changes in server usage.
Kakao said on the 22nd that it has improved the operation of the cooling system at a data center in Hanam, Gyeonggi Province, that is operated by LG CNS under contract. The improvement was an extension of the energy management experience from "Kakao Data Center Ansan" to a leased facility. Kakao applied the heat-management know-how it accumulated at its own data center to the leased data center.
Kakao pursued the improvement by adjusting operating conditions without replacing equipment. It did not carry out any new equipment replacements or expansions. Based on actual operating data and on-site conditions, it adjusted the cooling temperature in the server rooms and also adjusted the chilled-water temperature of the chillers based on actual operating data and on-site conditions.
During this process, Kakao applied LG CNS's AI agent to some server rooms. This improved energy efficiency.
Kakao said cooling power costs fell by about 23% on a comparison basis that reflects server usage and outside air conditions. The cooling power costs at the leased data center were reduced by about 23% from a year earlier.
Kakao explained that it maintained service stability despite record-breaking heat and changes in server usage. The company said service stability was maintained despite the heat wave and changes in server usage.
Kakao presented a plan to improve cooling efficiency based on data analysis. LG CNS, which participated in the operational improvements, adjusted the operating conditions of key cooling equipment based on its data center operating experience and equipment operation know-how. The equipment subject to adjustment included precision air conditioners (FWU) and chillers. LG CNS also confirmed stability at each stage.
LG CNS's AI agent developed by LG CNS was used in some server rooms. The AI agent analyzed the server room environment and equipment operating data in real time and supported autonomous control of the cooling equipment. It also helped maintain operating stability and reduce energy use.
Kakao operates Kakao Data Center Ansan on its own. At the Ansan data center, Kakao pursued optimization of cooling equipment, improvements to HVAC operations, greater efficiency in power equipment, and self-consumption of solar power. According to the company, the greenhouse gas reduction effect at the Ansan data center last year was 4,753 tCO2eq.
LG CNS and Kakao plan to expand the scope of energy efficiency improvements, starting with the Hanam data center application. The target includes leased facilities as well as the company's own data centers. This plan is intended to widen the scope of energy efficiency improvements from its own facilities to leased facilities, beginning with the Hanam data center application.
Leased facilities have the characteristic that equipment changes are limited. Accordingly, the two companies plan to adjust cooling methods based on operating data and site conditions, and they also plan to apply AI-based control technology. LG CNS plans to prioritize data center operational stability while simultaneously applying existing equipment operation efficiency improvements and AI-based autonomous cooling operation technology.
LG CNS plans to support customers in improving energy efficiency based on its data center operations expertise and AI technology. Kakao applied the data-driven heat-management know-how it accumulated at Kakao Data Center Ansan to the leased data center. Kakao said that as a result of applying this to the leased data center, it cut cooling power costs by about 23% and confirmed that energy efficiency can be improved by using operating data even in environments where equipment replacement is limited. Kakao said it will continue expanding eco-friendly data center operations.
