A kind of machine room supply air system
The utility model relates to a kind of machine room supply air system.
In communications equipment room, communication equipment has corresponding requirement to environment temperature.Usually, need to install enough air conditioners, with the whole equipment room cooling, so that satisfy the requirement of communication equipment to environment temperature.Because the machine room space is big, the wall heat transfer area is big, adds the leakage by door, window, and a large amount of energy have been wasted.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly can accurately deliver to communication cabinet in right amount with cold wind, satisfies communication equipment to the requirement of environment temperature and can save the energy, reduce the machine room supply air system of investment.
In order to realize above-mentioned utility model purpose, the technical scheme of employing is as follows:
A kind of machine room supply air system comprises cold wind equipment, communication cabinet and ajutage, and described cold wind equipment connects the inlet of ajutage, and ajutage is drawn some outlets and is connected to different communication cabinets respectively.
Described ajutage comprises air main and some branch wind pipes, and an end of described air main connects cold wind equipment, and the other end connects some branch wind pipes, and some branch wind pipes are connected to different communication cabinets respectively.
The junction of described air main and some branch wind pipes is equipped with volume adjusting apparatus.
Described volume adjusting apparatus is manual air-valve or Electric air valve or air-valve and blower fan composite set.
Adopt between the cabinet door of described branch wind pipe employing flexible pipe or branch wind pipe and communication cabinet and be flexible coupling.
Establish the airduct fixture on the described air main, be fixed on by the airduct fixture on the fixed frame of machine room.
Between the communication equipment cabinet tradition of a family road that a supply cold wind passes through is set in the cabinet door of described communication cabinet and the cabinet, and cabinet door is provided with a plurality of air vents.
Described cold wind equipment is air conditioner or air-cooler.
The utility model with respect to the beneficial effect of prior art is:
The utility model cold wind equipment by ajutage and volume adjusting apparatus, is transported to the cabinet tradition of a family road of communication cabinet after cold wind is pressurizeed by demand, pass the communication equipment in the rack then, exclude from the rack back, heat is taken away, get back to the return air inlet of cold wind equipment then.Because cold wind is accurately delivered to communication equipment, almost not loss can guarantee the communication equipment environment temperature midway, plays the effect of energy savings.The utility model small investment, high efficiency is convenient to implement.
Description of drawings
Fig. 1 is the structural representation of the utility model machine room supply air system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the machine room supply air system comprises cold wind equipment 1, air main 2, volume adjusting apparatus 3, branch wind pipe 4, cabinet door, cabinet tradition of a family road 5, communication cabinet 6 and airduct fixture 7, air main 2 is fixed on the fixed frame of machine room by airduct fixture 7, communication cabinet 6 is installed on the machine room floor 9, one end of air main 2 connects cold wind equipment 1, the other end connects some branch wind pipes 4, some branch wind pipes 4 are connected to different communication cabinet 6 respectively, in order to satisfy the requirement of machine room, airduct should select for use fire prevention, waterproof, heat insulation material to make; Volume adjusting apparatus 3 is located at the junction of air main 2 and branch wind pipe 4; In order to satisfy the needs that communication equipment upgrades, safeguards, should guarantee the normal opening and closing of cabinet door, adopt between the cabinet door of branch wind pipe 4 employing flexible pipes or branch wind pipe 4 and communication cabinet 6 to be flexible coupling.
Cold wind equipment 1 can be air conditioner or the air-cooler of going up air-supply, also can be the air conditioner or the air-cooler of air-supply down.The supply air system that Fig. 1 forms for the under-floor air distribution air-conditioning machine.Form supply air system if go up the air supply air-conditioner machine, the last air outlet of the air conditioner of only air main 2 need being plugged into gets final product, and all the other are constant.
Volume adjusting apparatus 3 can be manual air-valve, can Electric air valve, and also can be the combination of air-valve and blower fan, according to the needs of communication equipment in the rack, can close or open the size of regulating cold blast rate by volume adjusting apparatus 3.Satisfying under the prerequisite of communication equipment to the environment temperature requirement, suitably improving the temperature of machine room.
The utility model can be used for the transformation of newly-built machine room or old machine room.Need between the communication equipment to dispose the cabinet tradition of a family road 5 that a supply cold wind passes through in cabinet door and cabinet, cabinet door must have enough air vents, to guarantee enough draught areas in the rack.
The utility model can connect into network with many cold wind equipment and many row's communication cabinets in the machine room with airduct, form a bigger accurate supply air system, also many cold wind equipment and the many row's communication cabinets in the machine room can be divided into several less accurate supply air systems.
The utility model is accurately delivered to communication cabinet in right amount with cold wind, satisfies the requirement of communication equipment to environment temperature, suitably improves the temperature of machine room, reduce the machine that installs an air-conditioner, reduce the available machine time of air conditioner, reduce investment thereby reach, save the energy, reduce the effect of machine room operation cost.
