NEC Company developed and utilized natural ventilation to cut down the energy-efficient module of data centre that the air conditioner consumed energy by a wide margin a few days ago. Its principle is high-temperature air utilizing communication equipment of information to produce and introduces the temperature difference among the indoor outside air. This module is and the hot industrial company of Japan engaged in project business of the air conditioner, engaged in NECFielding Company of container type making and selling operation of data centre and common development of NSK Company.
This administrative legal person?s science and technology as Japan independently revitalizes the organization JST Subject for research carry on development, utilize technology of every company, has found out the operation information of the apparatus, used shape, indoor air flow state and temperature profile to change the mechanism, thus develop the products this time. Compared with application shape of the past data centre, the annual air conditioner consumes energy and can be cut down by about 60%. Make the size that uses up after adopting the delivery container that can utilize with the ordinary container type data centre.
Arrange into a framework of 1 to inhale in the underpart to the side of the module of side and set up and introduce the air inlet of the external air in the module, the top sets up the gas vent of the framework to the side of the relative module, the used heat that utilized outside air that sucked from the air inlet and the apparatus discharged. And adopt and arrange heat and promote the organization in order to improve the chimney effect. Through the above-mentioned action, have constructed not to use the natural ventilating system of the scavenger fan, can cool and discharge the used heat in the room.
Carry on the assessment with external possibility of air to natural ventilating system according to meteorological data, result reveal Tokyo have 26% time every year, thin pieces of wood used for writing on in ancient China heavy curtain have 14% time can utilize external air, through regulating the ventilating amount in severe cold season, then Tokyo can be lengthened to 65%, the heavy curtain of thin pieces of wood used for writing on in ancient China can be lengthened to 62%. In the future, will continue developing and making up and utilizing natural ventilation, apparatus ventilation and system of the air conditioner, strive to finish developing within 2013, in addition consider applying it to the large-scale data centre in order to advance commercialization.
