Detailed description of the invention
The explanation of embodiment in conjunction with the drawings, clearly will show other objects of the present invention except above-mentioned purpose and feature.
The preferred embodiments of the present invention will be described in detail by reference to the accompanying drawings.If when judging the illustrating fuzzy main idea of the present invention of related known structure of the present invention or function, will description is omitted.
Below, 2 to accompanying drawing 10 describes supply control method for heat and the device of boiler according to an embodiment of the invention in detail by reference to the accompanying drawings.
Fig. 2 illustrates the general structure of boiler and water pipe, is back to boiler 200 after being flow through the water pipe being arranged at room or room by the supply water that boiler combustion is heated.
During heat supply boiler the multiple water pipe of supply current direction in the water pipe of valve open state, therefore, the flow of circulation is different according to flowing through for the open/close state of the aqueduct valve of feedwater.Main idea of the present invention is, under without the condition of flow sensor by this heating cycle flow by preliminary heating period certain hour, within such as 3 minutes, calculate, utilize the heating cycle flow calculated, according to returning coolant-temperature gage by the suitable heat of sustainable supply, realize the minimizing of the heat supply/stopping time of boiler, reduce boiling noise, increase boiler life.
Fig. 3 illustrates the workflow diagram of the supply control method for heat of boiler according to an embodiment of the invention.
See Fig. 3, supply control method for heat select boiler heat supply function and when starting heat supply, utilize certain hour, within such as 3 minutes, supply the first heat set, by detecting supplying feed temperature and returning coolant-temperature gage of the above-mentioned supply first heat generation of 3 minutes, confirm to detect for feed temperature and return the difference of coolant-temperature gage, the stage S310, S320.
Described first heat is any one in the boiler heat that can supply, when for feed temperature rise to set safe temperature, such as more than 80 degree time boiler will be stopped, therefore, the temperature of its supply heat is preferred can prevent boiler from stopping, and is likely the minimum heat that boiler can supply according to one example.
Confirm the difference of two kinds of temperature in the S320 stage across certain hour, utilize the difference of the two kinds of temperature confirmed to judge heating cycle flow, stage S330.
Wherein, at flow as shown in Figure 4, two kinds of temperature difference T1 that first heat produces preferably judge that interval is maintained until to a certain degree, but, the slightly aobvious slowly rising of the temperature of feedwater is supplied by the coolant-temperature gage ratio that returns returning water after all water pipes by first rising for feed temperature after the supply of the first heat, for feedwater, therefore, Δ T1 is shown as identical in certain period or is shown as difference.Thus, more preferably judge that whether the two kinds of temperature difference T1 confirmed during the first heat supply are lower than below certain error, utilize two of below certain error kinds of temperature contrasts to judge heating cycle flow.
Certainly, judge the interval difference that can be confirmed two kinds of temperature by some cycles at the flow of Fig. 4, also can difference according to circumstances, judge interval last time point at flow or only confirm at a place of specific time point that the discrepancy delta T1 of two kinds of temperature is to judge heating cycle flow.
Preferably, the heating cycle flow judged in interval at flow also can judge according to following < mathematical expression 1> or calculate.
< mathematical expression 1>
Q=m×C×ΔT
Wherein, Q is supply heat, and namely refer to that flow judges the first interval heat, m is heating cycle flow, C be fluid, i.e. confession under directions to specific heat of water, Δ T be for feed temperature and return coolant-temperature gage difference, namely refer to that flow judges interval Δ T1.
Utilize after the S330 stage calculates heating cycle flow calculated heating cycle flow and with the real time detect return coolant-temperature gage to control the heat supply continued, impel returning coolant-temperature gage and be maintained until to a certain degree, stage S340.
Wherein, the heat supply control continued can impel and returns coolant-temperature gage and continue to rise to maintain and return water design temperature, preferably by the heat supply continued control by be maintained until for feed temperature utilize the discrepancy delta T1 of two kinds of temperature and user's setting return that water design temperature TR-set sets for feedwater design temperature Ref.T1.
Now, preferably equal to add two kinds of temperature difference T1 sums to returning water design temperature for the design temperature Ref.T1 of feedwater.
4 pairs of S340 stages of composition graphs are carefully described as follows:
As shown in Figure 4, be maintained until return water design temperature TR-set in order to coolant-temperature gage will be returned between thermal control zone, the heat supply carrying out continuing after supply is for the initial stage heat of Fast Heating for feedwater can be known, initial stage heat be can according to flow judge the stage return coolant-temperature gage, for feeding water, design temperature Ref.T1 and heating cycle flow decide.
According to circumstances do not consider that flow judges supplying feed temperature and returning coolant-temperature gage, for feedwater design temperature Ref.T1 and heating cycle flow, can set initial stage heat with the heat set of stage.Such as, the initial stage thermal settings that the stage that heat can be controlled supplies is the maximum heat Qmax that boiler can supply, and also can set by the value between minimum heat Qmin and maximum heat.
For after giving initial stage heat along with the increase returning coolant-temperature gage also makes the thermal change of supply, coolant-temperature gage can be returned according to what detect for feedwater design temperature Ref.T1, current time point and judges that heating cycle flow that the stage judges decides the heat that the heat control stage supplies at flow.
The heat that described heat controls stage supply can decide according to following < mathematical expression 2>.
< mathematical expression 2>
Q=(Ref.T1-TR)×m×C
In < mathematical expression 2>, C is the specific heat quotient of fluid, Ref.T1 and m is that flow judges the value that the stage determines, therefore heat controls the heat that supplies of stage is according to deciding according to the coolant-temperature gage TR that returns of time variations, usually increase in order owing to returning coolant-temperature gage, so reduce supply heat successively.Shown in an example as shown in Figure 4, confirm to return coolant-temperature gage according to certain hour unit, and utilize stage control to supply heat according to the certain hour cycle.
Being controlled the heat the continued supply in stage by heat, again judging heating cycle flow, stage S350 when returning when coolant-temperature gage maintains uniform temperature TR1.
Wherein, again judge that the reason of heating cycle flow is, if for correctly judging that heating cycle flow and implemented for long periods flow judge that the stage can postpone heating time and will cause that consumer's is discontented, so with certain period, within such as 3 minutes, judge, therefore, judge that the heating cycle flow that the stage judges is different from actual heating cycle flow at flow, different circular flow will cause returning coolant-temperature gage in the heat control stage and maintain not according to returning water design temperature TR-set, and be maintained until other temperature.
In the stage S350 of judgement again of heating cycle flow, for again judging that heating cycle flow may have multiple condition, this is illustrated as follows.
1) whether with return water design temperature TR-set identical returning if judging to return coolant-temperature gage TR1 in the state that coolant-temperature gage maintains to a certain degree, again judges heating cycle flow time different.
This is same as returns water design temperature TR-set owing to controlling at heat the coolant-temperature gage TR1 that returns that the stage is maintained until to a certain degree when judging that at flow the heating cycle flow that the stage judges is identical with actual heating cycle flow, returns when the heating cycle flow judged is different from actual heating cycle flow other temperature that coolant-temperature gage maintains irrevocable water design temperature.
2) judge that whether with first heat identical by returning coolant-temperature gage TR1 if maintaining the supply heat of certain state, judge heating cycle flow time different again.
This is owing to judging heating cycle flow with the first heat in the flow judgement stage, when the heating cycle flow judged is identical with actual heating cycle flow, make to return coolant-temperature gage be maintained until the supply heat of certain state will be identical with the first heat.When the heating cycle flow judged is different from actual heating cycle flow, makes to return the supply heat that coolant-temperature gage is maintained until certain state and will be different from the first supply heat.
3) judge that whether the feed temperature that supplies be maintained until to a certain degree judges the identical with the discrepancy delta T1 returning coolant-temperature gage for feed temperature of stage with flow with the discrepancy delta T2 returning coolant-temperature gage, judges heating cycle flow time different again.
This be also due in the flow judgement stage with for feed temperature with return coolant-temperature gage discrepancy delta T1 and judge heating cycle flow, when the heating cycle flow judged is identical with actual heating cycle flow, flow judge the stage for feed temperature with return coolant-temperature gage discrepancy delta T1 by be same as heat controls the stage for feed temperature with return coolant-temperature gage discrepancy delta T2, when the heating cycle flow judged is different from actual heating cycle flow, two value Δ T1, Δ T2 are also different.
Thus, heating cycle flow is can by such as above-mentioned 1) to 3) multiple condition come again to judge, thisly again judge that the time point of heating cycle flow can utilize and return coolant-temperature gage information or supply caloric information decides.
Such as, store successively and return coolant-temperature gage information or supply caloric information, coolant-temperature gage or supply heat is returned before what relatively current time point stored return coolant-temperature gage or supply heat and certain hour, the difference of two values lower than the value set, as C.T, compare below heat time determine as again judging heating cycle flow time point, this is described in detail at Fig. 4 to Fig. 7.
After again judging heating cycle flow as above-mentioned multiple condition, utilize the heating cycle flow that again judges to carry out supplementing supply heat and impel and return coolant-temperature gage and be maintained until and return water design temperature, stage S360.
Additional heat such as shown in Fig. 4 is interval in order to supplementary supply heat, utilize the confession feed temperature in heat control stage and return coolant-temperature gage discrepancy delta T2 and again will be set as Ref.T2 for the design temperature that feeds water, supplement supply heat impel for feed temperature be maintained until again set for feedwater design temperature Ref.T2, coolant-temperature gage will be returned and can be maintained until and return water design temperature TR-set.Now, flow can be become judge in the stage as judging the first heat that heating cycle flow supplies when returning the coolant-temperature gage supply heat maintained when returning water design temperature TR-set.
Supplementing by the supply heat in S360 stage, make to return coolant-temperature gage to maintain the state returning water design temperature to judge that heating cycle flow has unchanged, feed back to the follow-up S320 stage after supplying when heating cycle changes in flow rate the second heat set according to the change of heating cycle flow, the stage S370, S380.
Wherein, the the second supply heat supplied according to the change of heating cycle flow will differently set when heating cycle flow increases or reduces, and heating cycle flow can be judged as the change of heating cycle flow when the change that the additional heat stage is maintained until confession feed temperature to a certain degree or returns coolant-temperature gage becomes more than a reference value set during setting.
Now, for feed temperature or return when coolant-temperature gage rises to more than a reference value and can be judged as that heating cycle flow reduces, for feed temperature or return and can judge into heating cycle flow when coolant-temperature gage drops to below a reference value and increase.
Such as shown in Fig. 8 for feed temperature or return coolant-temperature gage maintain to a certain degree after when heating cycle changes in flow rate, be such as reduced to 6.5L from 13.5L time, after the time point t1 of heating cycle changes in flow rate, supply feed temperature and return coolant-temperature gage will sharply rise 810, when this temperature rises to more than a reference value, be judged as that heating cycle flow changes.
The heat supplied according to heating cycle changes in flow rate in the present invention namely, the second heat is when heating cycle flow reduces, sharply rise to prevent its temperature, preferably its heat is less than the heat supplement stage with the heat to a certain degree supplied, such as, be likely the minimum heat Qmin that boiler can supply.
And, decline owing to supplying feed temperature when heating cycle flow increases and returning coolant-temperature gage, second heat likely higher than the heat supplement stage with the heat to a certain degree supplied, but high heat supply can make sharply to rise for feed temperature, therefore, the supply heat supplement stage is preferably intactly maintained with the heat to a certain degree supplied.
