Description
Technical field
The present invention relates to fan speed regulation control fields, and in particular to a kind of optimal control method of heat-exchange fan.
Background technology
Outdoor integrated cabinet is with the advantages such as its construction period is short, construction cost is low, running cost is low on Communications Market
A large amount of application is obtained, but since interior of equipment cabinet is mounted with communication equipment and power supply, certain heat will necessarily be generated, this is just
It needs to radiate by temperature control device.The outdoor integrated common radiating mode of cabinet has air-conditioning, heat exchanger, direct ventilation etc.
Several ways whether using which kind of radiating mode, all be unable to do without wind turbine.In this way, wind turbine start after the noise that brings just not yet
It can avoid.Operator is often complained because noise disturbs residents.Therefore it is a class for being worth research to solve noise problem
Topic.
Below brief description once presently, there are heat exchanger wind turbine control method.
Not speed governing
The wind turbine of early stage carries out start-up and shut-down control merely by a temperature relay, does not carry out speed regulating control, undoubtedly
This control method cost is minimum, but noise is but the largest always.
(2) linear speed regulation
Speed governing curve is as shown in Figure 1 and Figure 2.Linear speed regulation scheme makes great progress than not speed governing.Increase in system
A controller and a temperature sensor are added.Controller carries out linear speed regulation control according to the temperature in cabinet and the curve of setting
System.It may be said that solves most noise problem.But it is regional at some, even if to night, environment temperature also has close
When 30 DEG C, temperature in cabinet may also can be at 37 DEG C or more, at this moment the rotating speed of wind turbine is still very high (calculates during with 37 DEG C
It is 69% to obtain inner blower rotating speed, and outer wind turbine is 61%), noise is also very big.Although some producers can be by wind turbine full speed running
Temperature spot sets to obtain higher or even 60 DEG C, but cannot thoroughly solve the problems, such as noise.
(3) improved linear speed regulation
Fig. 3, Fig. 4, Fig. 5, Fig. 6 are improved fan speed regulation curves.This improvement is reduced based on evening environment temperature
Afterwards, cabinet internal-external temperature difference is allowed to increase to realize the purpose for reducing rotation speed of fan, and then reduce the operation noise in evening.Still with evening
For upper outdoor environment temperature is 30 DEG C.If in-cabinet temperature is allowed to have 20 DEG C of Wen Sheng, inner blower rotating speed is 54%, outside
Rotation speed of fan 51%.There is apparent reduction than the noise before improvement.If daytime, when in-cabinet temperature breaks through 55 DEG C, wind
Machine rotating speed rapidly increases to maximum, makes in-cabinet temperature rapid decrease.If certain areas, night environment temperature is relatively low, at 25 DEG C
Hereinafter, the higher area to noise requirements, may be used this super mute control model of Fig. 5, Fig. 6.Wind turbine can in this way
To be run under 25% rotating speed, noise can be controlled in floor level.
Although improved controlling curve can further solve the problems, such as noise, improved control strategy is also deposited
Certain the defects of.
(1) there are two kinds of control models, it is impossible to automatically switch.
(2) controller does not detect ambient temperature, it is impossible to adjust turning for wind turbine according to the variation of cabinet internal and external temperature
Speed.
(3) controller not according to the time to determine whether be at night, can only be reduced by way of increasing the temperature difference
The rotating speed of wind turbine, the consequence brought in this way are to make the equipment long-term work in cabinet that may be reduced under higher temperature condition
The service life of equipment.
