Recently, Honeywell announced the launch of a liquid-cooled platform for cooling high-performance electronics. These new refrigerants reduce the running costs of applications such as data centers using high-performance servers.
According to the Global Market Research Corporation (GMI), data centers currently use approximately 3% of the world’s electricity, and it is expected that this number will rise to 8% by 2030. As the energy consumption of cooling systems accounts for approximately 40% of the total energy consumption, the demand for intelligent and energy-efficient solutions will drive the growth of the data center cooling market. In addition, the transition to 5G will also generate more demand for cooling solutions.
La Chris LaPietra, vice president and general manager of Honeywell Static Refrigerants, said: “The density of transistors in chips has become so small that these chips are generating a lot of heat.”
Paula Pietra says glycol or fans are not enough. Even moving to a colder climate is not enough. Solstice E-Cooling is the latest product on Honeywell’s next-generation low-GWP refrigerant technology production line. It uses a two-phase liquid cooling process to reduce the impact on the environment while transferring heat in electronics applications.
Compared with single-phase liquid cooling, two-phase cooling can achieve more energy-saving, more uniform cooling, better heat dissipation, and reduced pumping power. During single-phase liquid cooling, the liquid always remains liquid.
Solstice E-Cooling is also a dielectric solution. As an electrical insulator, it will not cause damage even if the equipment is in contact with liquid.
Honeywell also announced the introduction of Solstice N15 (R-515B), a new nonflammable, low global warming potential (LGWP) A1 refrigerant that can replace R-134a for refrigerators and heat pumps. Solstice N15 has a GWP of 299 (AR5).
This new refrigerant will be available this year. La Pietra said that it worked perfectly in equipment designed for Solstice ZE, the company’s older refrigerant. They are completely interchangeable, and N15 can still significantly reduce GWP.
StSolstice N15 has been adopted by compressor manufacturer Danfoss for its newly launched turbo TGS490 compressor, which can be used in air-conditioning applications for air or water-cooled chillers.
Paula Pietra said that Honeywell will continue to invest heavily in research and development at its plant in Buffalo, New York to find new refrigerant solutions. With the development of each generation, design becomes more and more difficult, and the cost of design becomes higher and higher. “We are still looking for new molecules,” La Pietra said. “If this is easy, we will have a new refrigerant this week, but it will not be so easy.”
