Panel schematic diagram, keeper by " optimizing regulation " one column, the setting of temperature difference temperature is switched to and " manually sets mould first
Formula ", then in " shaping modes " one column, is switched to " manual adjustment mode ", finally in " hand by valve opening " automatically adjusting "
" output MAN " in a dynamic control " column, keyboard keys in " 80 " and carriage return confirms, valve reality is now understood from monitored picture
The aperture 80% of feedback, manually control comes into force.
The 5 DEG C of temperature difference controls of water knockout drum end branch electric control valve root Ju are enabled, each end branch cold and hot amount balance is realized
With the energy hole of reallocation.As shown in figure 4, how " 1-3 floor fan coil in the middle part of C areas " branch road electric control valve is switched to root
It is as follows operation to be automatically controlled according to the temperature difference：In sign region mouse-click " TIC-07 " button, ejection picture is " C areas middle part 1-3 floor
How fan coil " branch road electric control valve is switched to the schematic diagram face-port mouthful automatically controlled according to the temperature difference；Keeper exists first
Chosen in " artificial control " column in " optimizing regulation ", temperature difference setting is switched to " artificial control model ", then in " setting
" 5.0 " are manually entered in " setting SP " column in parameter " and carriage return confirms, it is finally " automatic to adjust in " shaping modes " one column
Section " is chosen.Ratio P, integration I, differential D that suggestion user should not go to change in " PID regulations " column, and upper control limit and control
Lower data processed, because these data producers in equipment debugging, have been adjusted to optimal, user is without modification.Such as Fig. 5
Shown, " the big air-conditioning of B1 supermarket of A areas " branch road electric control valve guidance panel is switched to 5 DEG C of temperature difference and automatically controls.
" the big air-conditioning of B1 supermarket of A areas " water knockout drum end branch temperature difference setting value is searched according to COP Energy Efficiency Ratio maximum
Rope algorithm realizes that intelligent setting operation is as follows：As shown in figure 4, the authority account of initial landing engineer's rank, then in sign
Region mouse-click " TIC-06 " button, ejection picture is that water knockout drum end branch temperature difference setting value is very big according to COP Energy Efficiency Ratio
Value searching algorithm realizes that picture window is illustrated in intelligence setting；In " Based Intelligent Control " one column of keeper first in " optimizing regulation "
Choose, the branch road supply backwater temperature difference setting value is switched to " intelligent control mode ", then chosen in " shaping modes " one column
" automatically adjusting ".Do not change ratio P, integration I, the differential D in " PID regulations " column, and upper control limit and lower control limit number
According to, these data producers in equipment debugging, it has been adjusted to optimal, user is without modification；Meanwhile, do not change " parameter
Filtering h, frequency W, amplitude a, gain K in a setting " column, and the optimizing upper limit and optimizing lower data, these data producers
In equipment debugging, be adjusted to it is optimal, user without modification.
As shown in fig. 6, electric control valve aperture regulation and supply backwater temperature difference Collaborative Control, and realize overall energy consumption maximum journey
Degree energy-conservation J curve effectJ figure.Electric control valve aperture regulation and supply backwater temperature difference Collaborative Control, are ensureing end comfort level premise
Under, cold and hot amount more than needed is supplied to other cold and hot amounts demand great Zhi roads up, realize energy-conservation to the full extent.
Water knockout drum end branch timetable parameter is set, realizes certain electric control valve all the way on water knockout drum in the quitting time
17:Operation is automatically switched off after 30 as follows：" three layers of backwater, gastroscope " end branch realizes 17:30 are automatically switched off house steward's valve times
Table setting operation is as follows：The administrative public Administrative Area of doctor is traditional after doctor's quitting time in some special areas, such as hospital
Upper control does not consider to cut off the supply of cold and hot amount from branch road house steward, so as to cause the energy to transfer to make useless in pipeline overhead
The waste of work(, therefore this intelligent time list procedure just can very well solve the problem, with flexible parameter design function.For
Realize that " three layers of backwater, gastroscope " end branch realizes 17:30 are automatically switched off house steward's valve, it is only necessary to 17:30 moment started
To quitting time section below, former temperature difference setting value is improved to 2 to 3 times, at the normal boot-strap moment, automatic original of recovering just is set up
Definite value, the principle of design is according to big temperature difference low discharge.

Operation is as follows：Keeper is chosen in " Based Intelligent Control " one column first in " optimizing regulation ", and the branch road supply backwater temperature difference is set
Definite value is switched to " intelligent control mode ", then chooses " automatically adjusting " in " shaping modes " one column, in " PID regulations " column
Ratio P, integration I, differential D, and upper control limit and lower control limit data are provided with, filtering h, frequency are provided with " parameter setting " one column
Rate W, amplitude a, gain K, and the optimizing upper limit and optimizing lower data；So as to electric control valve aperture regulation and supply backwater temperature difference
Collaborative Control, under the premise of end comfort level is ensured, other cold and hot amounts demand great Zhi roads is supplied to by cold and hot amount more than needed
Up, energy-conservation to the full extent is realized.
5. end cold and hot amount is balanced and reallocation power-saving control method in central air-conditioning monitoring system as claimed in claim 1,
It is characterized in that certain electric control valve all the way on water knockout drum to be automatically switched off operation in the quitting time as follows：At a time
Start to quitting time section below, improve former temperature difference setting value to 2 to 3 times；It is automatic to recover original just at the normal boot-strap moment
Standing definite value, the principle of design is according to big temperature difference low discharge.
