Specifically, calculating the difference between the maximum conversion efficiency stored in the current transfer efficiency and the memory headroom
Value；If the difference is more than or equal to 0.1%, the corresponding relationship between the corresponding status information of current transfer efficiency is stored

And sensitivity, to guarantee the real-time of data acquisition, while the response time between each sensor should also be as quite, not going out
Existing excessive delay, and lead to the invalid of data.
The heat balance point η newly obtainedxIt is worth and is stored in η maximum value in memory headroom and compare, if more than memory sky is stored in
In η maximum value, then the η of the heat balance point of the new acquisitionxIt is worth corresponding data module and is stored in the corresponding number of η maximum value
According to a upper site for module；It is not stored if being less than the maximum value.The effect of this method is to obtain maximum thermal efficiency value；Until
Seek until optimum operating condition.Above-mentioned method is optimal state, that is, thermal efficiency value when each heat balance point obtained is equal
Be it is incremental, the full memory headroom could be stored in this way.
It will be detailed below how judging the η of next heat balance pointxValue be greater than existing memory headroom maximum value with
And the method for evaporator circuit valve how is controlled to guarantee in real time to be monitored the operating condition of evaporator.
Firstly, the heat balance point η that controller newly obtains judgementxWhether value is greater than the existing heat balance point in memory headroom
Maximum ηxValue；Judged by mathematical relationship function.
If the heat balance point η newly obtainedxValue is less than the existing heat balance point maximum η in memory headroomxValue, then controller control
Evaporator circuit valve processed increases or reduces flow；Operating condition when thermal balance can thus be changed, then controller is counted again
Calculate the η for being adjusted the heat balance point after evaporator circuit valvexValue；
The heat balance point η being calculated again is judged againxIt is flat whether value is greater than the maximum heat being stored in memory headroom
Weigh point ηxValue, if the heat balance point η calculated againxValue is greater than the maximum heat balance point η in memory headroomxValue then this count again
The heat balance point η of calculationxIt is worth the maximum heat balance point η that corresponding data module is stored in memory headroomxA upper site for value,
And controller continues to increase or reduce the flow of evaporator circuit valve.The flow for even increasing evaporator circuit valve makes ηx
Value becomes larger, then when changing thermodynamical equilibrium operating condition next time, controller then increases the flow of evaporator circuit valve, if reducing
The flow of evaporator circuit valve makes ηxValue becomes larger, then when changing thermodynamical equilibrium operating condition next time, controller then reduces
The flow of evaporator circuit valve.Such as the η of first timexValue is 50%, and second when increases 1% evaporator circuit valve
Flow, so that secondary η when reaching thermodynamical equilibriumxValue becomes 50.8%, then changes thermodynamical equilibrium work in third time
When condition, the flow of evaporator circuit valve should be greater than 1%, for example, 1.5% compared with for the first time；When being selected as reduction flow
Mode when, with increase flow mode as, herein without repeating.
If the heat balance point η being calculated againxValue is less than the maximum heat balance point η in memory headroomxValue, then do not store
To memory headroom, and controller control evaporator circuit valve adjusts flow in reverse direction, that is, flow is reduced or increased；Directly
It is filled to memory headroom.For example, the η of such as first timexValue is 50%, and second when increases 1% evaporator circuit valve
Flow so that secondary η when reaching thermodynamical equilibriumxValue becomes 49.8%, then changes thermodynamical equilibrium in third time
When operating condition, the flow of evaporator circuit valve should be adjusted back, i.e. reduction flow, and should be smaller than the flow value of first time.
Above-mentioned mode recycles always progress, until memory headroom is filled.
In addition, it is necessary to illustrate, first time described in above-mentioned example, second and third time are a relative concepts, i.e.,
The selection of the heat balance point three times of arbitrary continuation is all successively assumed to for the first time, for the second time and for the third time.
In addition, as a kind of preferred mode, in order to avoid the thermal efficiency value mistake adjacent when reaching thermodynamical equilibrium
In close, and storage update is carried out, causes data to update excessively frequent, such as the thermal efficiency value of first time is 35.82%, second
Secondary thermal efficiency value is 35.85%, if replacing 35.82% for 35.85%, then seems and is not necessarily to, therefore, deposit for the first time
During full memory headroom, established standards are accepted or rejected to adjacent data.
The heat balance point η being even calculated againxValue is greater than the maximum heat balance point η being stored in memory headroomxValue
When, judge the heat balance point η being calculated againxThe maximum heat balance point η for being worth and being stored in memory headroomxThe difference of value,
When the difference is greater than 0.1%, the heat balance point η that is calculated againxIt is worth corresponding data module and is stored in memory headroom
Interior maximum heat balance point ηxIt is worth a upper site for corresponding data module；It is not stored if less than 0.1%, controller continues to adjust
The flow of whole evaporator circuit valve.I.e. first time thermal efficiency value is 48.53, %, and secondary thermal efficiency value is 48.55%,
It is then unnecessary that the corresponding data module of thermal efficiency value 48.55% of second of heat balance point is stored in memory headroom.
When memory headroom stores full for the first time, whole system is also in orderly running, and working condition and external environment
All in variation, it is therefore necessary to carry out further optimizing to floor data, guarantee the lasting effectiveness of floor data.It is several
Heat balance point ηxValue is filled with after memory headroom for the first time, and controller continues evaporator circuit valve and increases or reduces flow；
It calculates and is arbitrarily once filled with the heat balance point η after memory headroomxValue；Calculate the thermal efficiency value of this heat balance point
When, the control of device circuit valve is evaporated when should expire memory headroom to store based on the heat balance point of last time；Its
For example above-mentioned valve control method of method.
First determine whether the heat balance point η being arbitrarily once filled with after memory headroomxValue (hereinafter referred to as rear ηxValue) with storage in
Deposit the maximum heat balance point η in spacexThe size of value；If the rear ηxValue is greater than the maximum heat balance point η in stored memory spacexValue, then
The rear ηxIt is worth the maximum heat balance point η that corresponding data module is stored in memory headroomxIt is worth a upper site for corresponding data module,
Controller continues to control the η that evaporator circuit valve change flow continues calculating heat balance pointxValue.
If the rear ηxValue is less than the maximum heat balance point η in stored memory spacexValue, does not store, and controller continues control evaporation
Device circuit valve changes flow and continues to calculate the η of heat balance pointxValue.
It will be detailed below the control method of the evaporator circuit valve of the process.
First determine whether rear ηxValue is greater than the maximum heat balance point η in stored memory spacexValue, then controller control evaporator returns
Road valve continues growing or reduces flow until calculating heat balance point η next timexValue；If η after judgementxIt is empty that value is less than stored memory
Between maximum heat balance point ηxValue, then flow is reduced or increased until calculating next time hot in controller control evaporator circuit valve
Equalization point ηxValue.I.e. if first time controller control evaporator circuit valve increases flow, obtained secondary heat is flat
The η of weighing apparatus pointxValue increases, then should also increase when third time changes evaporator circuit valve flow, if being for the first time similarly to subtract
Small flow is also to reduce when then third time changes evaporator circuit valve flow.
Certainly, if increasing flow for the first time, the η of obtained secondary heat balance pointxValue becomes smaller, then third time
Flow should be reduced when changing evaporator circuit valve flow, and it is smaller than secondary flow, or even when than first time
Flow is small.
In addition, in order to eliminate error amount, if η after judgementxValue is greater than the maximum heat balance point η in stored memory spacexWhen value,
It should continue η after calculatingxThe maximum heat balance point η of value and stored memory spacexThe difference of value, if difference is greater than or equal to 0.1%
Then be stored in memory headroom, do not stored if less than 0.1%, controller continue control evaporator circuit valve change flow into
Row calculates next time.
