FOCUS on RACKS AND CABINETS
MODULAR COOLING SOLUTION Hitachi has developed the refrigerant Natural Circulation system (NC system), saving energy by eliminating the need for a power source to drive operation.
NATURAL CIRCULATION – THE BESPOKE
THE TECHNOLOGY Hitachi’s NC system requires no pump or
compressor. The heat from the server vaporises the refrigerant, causing it to rise. When cooled, it condenses and falls. Utilising these rising and falling streams, the system circulates the refrigerant without an externally powered driving force.
NC RACK Half the width (300mm) of standard server racks, rack type air conditioners takes up far less space than conventional models, providing 23kW of cooling capacity.
The warm air from
the server is exhausted to the back of the rack where it is sucked in by the adjacent rack type
air conditioner. It is cooled and vented to the front as a stream of chilled air, which the server then takes in creating a cooling cycle.
NC DOOR Rear door cooling units attach to the back of server racks to provide 10kW of cooling capacity. The air conditioner directly takes the heat exhausted from the server and rejects it at optimal room conditions, allowing a high degree of server integration.
The Cloud Unit resides above IT Racks enabling additional IT capacity within data halls by
eliminating the need for large CRAC units located along corridor fl oors, providing 15kW of cooling capacity. Refrigerant pipework is located above the isle eliminating the need for a raised fl oor.
SCALABLE AND FLEXIBLE Easy integration to new and existing facilities provide customers with a tailor-made solution as Hitachi recognises the necessity for bespoke and cost effi cient answers to data centre needs.
