en.Wedoany.com Reported - NTT Facilities, the construction and engineering division of NTT, has recently expanded its FMACS-VI air conditioning product line with the launch of a high-capacity downflow model, the FMACS-VI(LL), offering a cooling capacity of 63kW. Designed for high-heat-generating telecommunications equipment rooms and data center server rooms, this unit represents an improvement over the previous generation FMACS-V(LL) model's 56kW. Developed in collaboration with cooling equipment supplier Daikin, it is a high-capacity version of the sixth-generation FMACS-VI series. NTT states that the unit is 20% more efficient than the base model and is the first to use R32 refrigerant, which has a lower global warming potential than the traditionally used R410A.

NTT plans to further expand the FMACS-VI series to meet demand following the enforcement of traditional refrigerant regulations in 2029. This includes high-capacity upflow models for large telecommunications equipment rooms, data centers, and direct ground areas such as power rooms and equipment rooms, as well as small-capacity models for small telecommunications equipment rooms.

NTT and Daikin are also collaborating on a new Artificial Intelligence proof of concept. The two companies will leverage NTT Data's operational expertise and data on the relationship between server behavior and cooling performance, combined with Daikin's cooling system control technology and AI control capabilities, to jointly develop an AI model for predicting server thermal conditions. They will also establish a new cooling optimization method that integrates AI-based thermal prediction with facility control systems. From July 2026 to March 2027, this solution will be deployed at an NTT Data data center in Japan to evaluate its effectiveness in improving energy efficiency, reducing electricity costs, and enhancing operational automation.
