Energy Integrations for Data Centers
  • Based on the framework of “Energy Saving, Energy Utilization, and Energy Generation”, Kaori is proposing the energy integration solution, or the“Energy Trio”. With the cloud data center as the main axis, the company proposes a liquid cooling solution for server cooling, and in the backup power support, the hydrogen technology is combined with a 5kW methanol fuel cell, and combined with a high-force plate heat exchanger. Waste heat recovery management can increase the overall energy efficiency by more than 40%, and fully demonstrates innovative thinking and complete technical capabilities in the energy field.

Data center cooling

Energy Trio
  • Energy Generation - Fuel Cell Generators
  • Energy Preservation - Liquid Cooling System for Servers
  • Energy Recovery - Heat Exchanger/Heat Pump
◎ Energy Trio - 1
 ◆ Energy Generation - Fuel Cell Power System
  • Kaori hydrogen fuel cell power generator is safe, high efficiency, clean and green energy, and can operate stably for a long time. It can be used as auxiliary power, emergency backup power, independent power supply, and integrated power generation. Replacing the dilemma of traditional highly-polluted diesel power generators and a large number of hydrogen cylinders, using low-environment hazard, high energy density, convenient storage and transportation, safe methanol water, natural gas, real estate hydrogen, immediate consumption, combined with self-made remote monitoring system, let green electricity go everywhere .

 ◆ Energy Preservation – Liquid Cooling System
  • With the continuous improvement of the world's awareness of energy conservation and carbon reduction, how to effectively reduce the energy consumption of data centers has become a major concern in the telecommunications industry. All e-commerce giants face more serious cooling issues in their self-built data centers. Kaori’s immersion cooling system is rigorously verified by cloud servers, generating huge amounts of heat during fast and large data volumes. Kaori’s high cooling capacity immersion coolant distribution unit(CDU) plays an important role.
