Description
Technical field
The present invention relates to the machine room refrigeration technology field, relate in particular to a kind of rack, and this rack is accurately controlled the method for air quantity.
Background technology
According to statistics, in the middle of the huge energy consumption of machine room was formed, air conditioning energy consumption had occupied more than 40%.In order to guarantee the long-time operation reliably of server, the server room disposes 24 hours air-conditionings usually to reduce computer room temperature.Present most machine room heat radiation strategy is by reducing the temperature that machine room bulk temperature rack installation simultaneously fan reduces erection unit in each rack and the rack.
Reduce cabinet temperature by reducing the machine room bulk temperature, cold is passed in the room needs in the rack through rack, prolonged the time of server cooling to a certain extent, cause room temperature very low easily, the situation that temperature in the rack but remains high, simultaneously to whole equipment room air-supply temperature reduction way, increased the cooling area, increased the operating time of air-conditioning equipment, the loss of cold and the consumption of the energy have also been increased, though some enclosure top is equipped with radiator fan, make that the server radiating effect at top is better, the server radiating effect of middle lower curtate but is not very desirable.
In order to solve this technical barrier, there is the technical staff to propose the technical scheme that a kind of air-conditioning directly is communicated with rack.For example, Chinese patent literature CN202713866U discloses a kind of " cooling machine cabinet system ", it comprises air-conditioning, the supply air duct that is communicated with the air-conditioner air outlet of being located at the air-conditioning bottom, also comprise the return airway of being located at each enclosure top, the baffle plate of each rear of cabinet, described return airway is communicated with the air-conditioning return air inlet that is located at air-conditioning top, each rack bottom is equipped with a rack air intake vent, and the rack air intake vent communicates with supply air duct, rack air intake vent place be provided with can before and after the slip lid of slip.Though this energy-conservation cooling rack forms the kind of refrigeration cycle of sealing by directly being communicated with refrigeration air-conditioner, has promoted cooling rate.But, because this cooling machine cabinet system only controls air quantity by the slip lid of rack bottom, can't reach the accurate control to air quantity, can not realize that equally temperature cooperates with the real-time of air quantity size, cause the significant wastage of cold air resource, reduced the refrigerating efficiency of rack and the utilance of resource.
