Trane Technologies cuts data center HVAC energy use with HFO refrigerants and liquid cooling

Data center energy use is expected to triple by 2030, with HVAC systems accounting for 30 to 40 percent of facility power consumption. Trane Technologies is addressing this through a shift to HFO refrigerants, which now make up 70 to 80 percent of its Asia Pacific portfolio, and through acquisitions of liquid cooling companies LiquidStack and Stellar Energy. The company's Gigaton Challenge aims to cut one billion metric tons of customer carbon emissions by 2030, with 331 million tons already removed. Trane also emphasizes in-region manufacturing and local R&D to tailor solutions for different climates, such as Australia's varied conditions. By offering energy audits and ROI-based proposals, the company helps building owners reduce operating costs while keeping existing equipment running until fully amortized. The move toward liquid-to-chip cooling is positioned as a likely standard for future data center thermal management.
