Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment and only be not used in restriction scope of the present utility model for the utility model is described, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present utility model.
If Fig. 1 is a kind of data center of centralized management frozen water type air conditioner in machine room, comprise: chilled water allocation units, precise machine room air conditioner unit, server cabinet, be to be understood that the listed equipment of this figure is only for illustrating principle of the present utility model, in data center, other equipment all do not comprise.The freezing water source of chilled water allocation units described in the utility model needs building chilled water to provide, as machine room place building do not have 24 hours uninterrupted chilled waters, and need be at the outdoor refrigerating water sets of separately joining.
Chilled water allocation units comprise master control section and many sections, master control section is connected with filter, temperature/pressure measuring section and the first valve in turn, this valve adopts ball valve, and many articles sections are connected with the second valve and the 3rd valve, and after collecting and refrigerating water sets be connected to form loop.Thereby and between the second valve and the 3rd valve, precise machine room air conditioner unit is set and provides low-temperature receiver to carry out heat exchange.The chilled water of handpiece Water Chilling Units or building the inside is flowed to precise machine room air conditioner unit by chilled water allocation units, water after the heat exchange of precise machine room air conditioner unit enters chilled water handpiece Water Chilling Units or building by chilled water allocation units again, chilled water allocation units are equipped with adjustable valve, it can facilitate user to carry out water conservancy balance adjustment to the cold feed of air-conditioning between frozen water type row, realizes distribution according to need.Simultaneously can safety air-conditioning is carried out to supply and the shutoff of chilled water, needn't enter cold passage area.By 2 embodiment, the utility model is specifically described now.
embodiment 1
If Fig. 2 is the pipeline system schematic diagram that the utility model embodiment 1 adopts.It should be noted that the present embodiment legend illustrates with 12 loops, be to be understood that the utility model also contains other number loops and do not limit the utility model with loop quantity.
The master control of described chilled water allocation units comprises water filter 31, temperature/pressure measuring section 32, the first valves (ball valve) 33; And every section all comprises pipe joint 34, connecting line 35, the second valves and the 3rd valve (hydraulic equilibrium valve) 36; Precise machine room air conditioner unit comprises fan unit 21, heat exchanger unit 22, Flow-rate adjustment valve cell 23.Enter after chilled water allocation units from the freezing freezing water source that freezes water or handpiece Water Chilling Units of building, enter 12 distribution circuit through water filter 31, temperature, pressure measuring section 32, ball valve 33 successively, every road pipeline comprises again the second valve, connector 34, connecting pipe 35.Then chilled water enters the precise machine room air conditioner cell mesh in dotted line frame, and precision air conditioner unit department is mainly responsible for the heat that absorption data central server distributes as mentioned above, maintains the temperature range of desired 24 ± 1 DEG C of data center.Absorption data central concentrated load temperature rises to chilled water to connecting pipe and the connector of the approximately 12 DEG C hydraulic equilibrium valve 36 of flowing through again and is back to building chilled water or handpiece Water Chilling Units.
Be quick union as preferred chilled water allocation units 2 to the connector 34 of precise machine room air conditioner unit 3.The installation and debugging stage does not need to employ welding equipment and just chilled water allocation units can be connected with precise machine room air conditioner, and this feature is particularly important to machine room security against fire.Comprise that the work such as later maintenance, the renewal of the equipment replacement all can directly not use soldering set and manually complete, improve computer room safety performance.
Be immunity flexible pipe as preferred chilled water allocation units 2 to the connecting pipe 35 of precise machine room air conditioner unit 3, immunity flexible pipe anti-twisting property is strong, full pipe-line system no-welding-spot.As adopt copper pipe welding manner, cannot effectively prevent that the leakage of solder skip rosin joint from occurring.
It should be noted that, in the present embodiment, the 3rd valve (hydraulic equilibrium valve) 36 is static balancing valve.Static balancing valve should be used for constant flow water system, is that three-way flow regulating valve 23 is constant to ensure flow system flow in precise machine room air conditioner 2.Static balancing valve 36 is linear pattern discharge characteristic, all has good Flow Adjusting Performance in the time of big or small aperture, and especially in the time of little aperture, anti-cavitation erosion and hydrodynamic noise are stronger.
It should be explicitly made clear at this point, can not use as static balancing valve as valves such as ball valve, butterfly valve, gate valves for other valve classes, its main cause is that its valve flow characteristic is fast open form, and, in the time of the little aperture of valve, even if valve event is very little, flow amplification is very large.And in the time of large aperture, valve event is very large, and that flow changes is very little, in addition this type of valve cannot be in the time of little aperture anti-cavitation erosion and noise ability.
embodiment 2
If Fig. 3 is the pipeline system schematic diagram that the utility model embodiment 2 adopts.It should be noted that the present embodiment legend illustrates with 12 loops, be to be understood that the utility model also contains other number loops and do not limit the utility model with loop quantity.Compared with embodiment 1, the difference part of the present embodiment 2 is to use dynamic differential pressure balancing valve 37, correspondingly in precise machine room air conditioner 2, adopts two logical proportional flow control valves 24, and the discharge of the precise machine room air conditioner 2 of flowing through is variable value.Variable flow system compared with the power savings advantages of constant flow water system increasingly extensive accept and adopt, the key character of variable flow system is that the actual waterpower operating condition of system and design conditions exist greatest differences, system internal drop distributes and is different from design conditions completely thus.As air-conditioning system operates under sub-load, as still used static balancing valve, because static balancing valve cannot be eliminated the excess enthalpy pressure at two logical ratio adjusting valve two ends, cause the water yield of passing through to be greater than actual demand, consume water pump excess power.The little temperature difference operation of large flow in addition, makes handpiece Water Chilling Units depart from 7～12 DEG C of designed temperature differences, and water temperature declines 1 DEG C will cause refrigerating efficiency low 3%～5%.
In addition also can use dynamic differential pressure balanced type electric control valve to replace static balancing valve or dynamic balance valve, due to built-in differential pressure controller and electric control valve, can reduce the influence of fluctuations of driver drives number of times little.
