March 2016 Cutting Edge Cooling Facility Phase Change Cooling Unit COOLING UNIT TO REDUCE DATACENTER OPERATING COST NEC’s Phase Change Cooling Unit is a very innovative facility to support datacenters’ efficient operation. Coolant vaporizes exhaust heat to move upward outside the datacenter. Cooled and liquefied coolant returns to the server racks to repeat circulation. The heat can be removed from servers efficiently without using electric power. Cooling Power Consumption Reduced by 30 *1 % Renting Space Cost: Reduced by 30 Energy Efficient Power Consumption Reduction *1 % Space-Saving Safety & Green Renting Space Cost Reduction Safe and Green Coolant Phase change cooling unit removes 50% of The unit enables to mount more ICT devices The coolant is solvent having high safety and utilizing electric power. It reduces power Datacenter capabilities can be enhanced and environment. Global Warming Potential exhaust heat to outside datacenter without consumption required for cooling by 30%. on racks without increasing cooling capacity. without space expansion. capable of minimizing influences to human value is ¼ of general air conditioning refrigerant (R134a). It is nonflammable, electrically insulated and practically non-toxic.*2 *1 Effects may vary by datacenter. *2 “Practically non-toxic” on acute inhalation toxicity according to the guidelines of U.S. EPA PHASE CHANGE COOLING UNIT Advantages: ●Newly developed multiple heat exchangers effectively and evenly remove the heat from each ICT device. The unit removes 50% of exhaust heat from 30kW ICT devices. Total exhaust heat Servers Unit removing rate Rack top ●The coolant is safe and environmentally friendly and have no affect on the human body. ●Coolant circulates through multiple heat exchangers installed on the back of a rack and a plumbing attached on top to move heat outside datacenter without electrical power. ●No periodic maintenance is required for the circulating system has neither mechanical nor electrical parts and the coolant circulate in the system almost permanently.
