Hitachi GLS IT Equipment Air Conditioning Unit Cooling Tower Heat Dissipation Type / Water-Cooled
Hitachi Global Life Solutions
Cooling tower heat dissipation type / water-cooled air conditioning unit for IT equipment that does not bring cooling water into the IT room.
No cooling water is brought into the IT equipment room. By installing the water-cooled unit outside the IT layer geology, there is no need to bring cooling water piping into the IT equipment room. Issues such as cooling water leaks within the IT equipment room have been eliminated. (The water-cooled unit is designed for indoor installation.) Refrigerant piping length of 160m. The on-site connected refrigerant piping [between the indoor unit and the water-cooled unit] also achieves an actual length of 160m. The layout of the cooling tower, water-cooled unit, and indoor unit can be easily planned. Low-temperature cooling water compatibility. By applying low-pressure ratio control similar to air conditioning systems, the high pressure can be reduced as much as reliability allows, enabling operation with a cooling water inlet temperature of up to 5°C. Reduction of rooftop installation space. A compact cooling tower is used instead of an air-cooled outdoor unit. Therefore, the layout of the rooftop can be easily planned. Easy adaptation to existing buildings (installation of water-cooled heat source equipment for building updates). For more details, please contact us.
