Fig. 3 illustrates the workflow diagram of the supply control method for heat of boiler according to an embodiment of the invention.
Referring to Fig. 3, supply control method for heat is in the heat supply function of selecting boiler and when beginning heat supply, utilize certain hour, for example supplied with first heat of having set in 3 minutes, by detecting the supply coolant-temperature gage that 3 minutes first heat of above-mentioned supply produces and returning coolant-temperature gage, confirm detected supply coolant-temperature gage and the difference of returning coolant-temperature gage, stage S310, S320.
Described first heat is any one in the heat that can supply with of boiler, coolant-temperature gage rises to the safe temperature set, boiler will be stopped when for example 80 degree are above when supplying with, therefore, its temperature of supplying with heat stops to preferably can prevent boiler, might be the minimum heat that boiler can be supplied with according to the one example.
Difference in the S320 stage across two kinds of temperature of certain hour affirmation utilizes the difference of two kinds of temperature confirming to judge the heat supply circular flow, stage S330.
Wherein, two kinds of temperature difference T1 that first heat produces preferably judge that at flow as shown in Figure 4 the interval is maintained until to a certain degree, but, supply with afterwards coolant-temperature gage rising earlier, supply with water returns water afterwards by all water pipes the apparent slightly slowly rising of temperature that the coolant-temperature gage ratio is supplied with water of returning by the supply of first heat, therefore, Δ T1 is shown as identical during necessarily or is shown as difference.Thus, judge more preferably whether two kinds of temperature difference T1 that confirm are lower than below certain error during first heat is supplied with, utilize two kinds of following temperature contrasts of certain error to judge the heat supply circular flow.
Certainly, judge the interval difference that can confirm two kinds of temperature by some cycles at the flow of Fig. 4, difference that also can be according to circumstances, judge interval last time point or only confirm that at a place of specific time point the discrepancy delta T1 of two kinds of temperature judges the heat supply circular flow at flow.
Preferably, judge that at flow the heat supply circular flow in the interval also can be according to following＜mathematical expression 1〉judge or calculate.
＜mathematical expression 1 〉
Q?=?m×C×ΔT
Wherein, Q supplies with heat, refers to that namely flow judges the first interval heat, and m is the heat supply circular flow, and C is fluid, is the specific heat of confession under directions feedwater, and Δ T supplies with coolant-temperature gage and returns the difference of coolant-temperature gage, namely refers to that flow judges interval Δ T1.
Utilize the heat supply circular flow that calculates after calculating the heat supply circular flow in the S330 stage and control lasting heat and supply with the detected coolant-temperature gage that returns of real time, impel and return coolant-temperature gage and be maintained until to a certain degree stage S340.
Wherein, the heat that continues is supplied with control and can be impelled and return coolant-temperature gage and continue to rise to keep and return the water design temperature, preferably supplies with control by the heat that continues and will supply with the supply water design temperature Ref.T1 that water design temperature TR-set sets that returns that coolant-temperature gage is maintained until the discrepancy delta T1 that utilizes two kinds of temperature and user's setting.
At this moment, the design temperature Ref.T1 that preferably supplies with water equals to add two kinds of temperature difference T1 sums to returning the water design temperature.
Carefully be described as follows in conjunction with the S340 of Fig. 4 stage:
As shown in Figure 4, be maintained until and return water design temperature TR-set in order to return coolant-temperature gage at the heat control interval, can know the heat supply that continues behind the initial stage heat of supplying with to Fast Heating supply water, the initial stage heat is to judge that return coolant-temperature gage, supply water design temperature Ref.T1 and the heat supply circular flow in stage decide according to flow.
According to circumstances do not consider the supply coolant-temperature gage in flow judgement stage and return coolant-temperature gage, supply water design temperature Ref.T1 and heat supply circular flow, can set the initial stage heat with the heat of having set.For example, the initial stage heat that the stage of heat can being controlled is supplied with is set at the maximum heat Qmax that boiler can be supplied with, and also can set with the value between minimum heat Qmin and the maximum heat.
After having supplied with the initial stage heat, also make the thermal change of supply along with the increase of returning coolant-temperature gage, can decide the heat that the heat control stage supplies with according to supplying with water design temperature Ref.T1, the detected heat supply circular flow that returns coolant-temperature gage and judge in the flow judgement stage of current time point.
The heat supplied with of described heat control stage is can be according to following＜mathematical expression 2〉decide.
＜mathematical expression 2 〉
Q?=?(Ref.T1-TR)?×m×C
＜mathematical expression 2〉in, C is the specific heat quotient of fluid, Ref.T1 and m are that flow is judged the value that the stage determines, so the heat that the heat control stage is supplied with is to decide according to the coolant-temperature gage TR that returns that changes according to the time, usually increase in order owing to returning coolant-temperature gage, supply with heat so reduce successively.Shown in the example as shown in Figure 4, confirm to return coolant-temperature gage according to certain hour unit, and utilize stage control to supply with heat according to the certain hour cycle.
The heat that continues by the heat control stage is supplied with, and judges heat supply circular flow, stage S350 when coolant-temperature gage maintains uniform temperature TR1 again when returning.
Wherein, the reason of judging the heat supply circular flow again is, if judge that for correct the heat supply circular flow implemented for long periods flow judgement stage can postpone heating time and will cause being discontented with of consumer, so with during certain, for example judged in 3 minutes, therefore, the heat supply circular flow of judging in the flow judgement stage is different from actual heat supply circular flow, different circular flow will cause returning coolant-temperature gage in the heat control stage to be kept not according to returning water design temperature TR-set, and is maintained until other temperature.
In the stage S350 of judgement again of heat supply circular flow, for judging the heat supply circular flow again multiple condition may be arranged, this is carried out following explanation.
1) maintains and judge in to a certain degree the state and return coolant-temperature gage TR1 whether with to return water design temperature TR-set identical returning coolant-temperature gage, judge the heat supply circular flow when different again.
This is because the coolant-temperature gage TR1 that returns that is maintained until to a certain degree in the heat control stage when flow judges that heat supply circular flow that the stage judges is identical with actual heat supply circular flow is same as and returns water design temperature TR-set, returns other temperature that coolant-temperature gage maintains irrevocable water design temperature when the heat supply circular flow of judgement is different from actual heat supply circular flow.
2) judge whether with first heat identical by returning coolant-temperature gage TR1 if maintaining the supply heat of certain state, judge the heat supply circular flow in the time of different again.
This be since in the flow judgement stage with first heat judgement heat supply circular flow, when the heat supply circular flow of judging is identical with actual heat supply circular flow, make return the supply heat that coolant-temperature gage is maintained until certain state will be identical with first heat.When the heat supply circular flow of judging is different from actual heat supply circular flow, makes and return supply heat that coolant-temperature gage is maintained until certain state and will be different from first and supply with heat.
3) judge that whether the supply coolant-temperature gage that is maintained until to a certain degree and the discrepancy delta T2 that returns coolant-temperature gage judge that with flow the supply coolant-temperature gage in stage is identical with the discrepancy delta T1 that returns coolant-temperature gage, judge the heat supply circular flow again when different.
This also be since in the flow judgement stage with supplying with coolant-temperature gage and returning coolant-temperature gage discrepancy delta T1 and judge the heat supply circular flow, when the heat supply circular flow of judging is identical with actual heat supply circular flow, the supply coolant-temperature gage that flow is judged the stage with return supply coolant-temperature gage that coolant-temperature gage discrepancy delta T1 will be same as the heat control stage and return coolant-temperature gage discrepancy delta T2, also difference of two value Δ T1, Δ T2 when the heat supply circular flow of judging is different from actual heat supply circular flow.
Thus, the heat supply circular flow be can by as above-mentioned 1) to 3) multiple condition judge that again this time point of judging the heat supply circular flow again can utilize and return coolant-temperature gage information or supply with caloric information and decide.
Such as, store successively and return coolant-temperature gage information or supply with caloric information, more current time point stores returns coolant-temperature gage or supplies with returning coolant-temperature gage or supplying with heat before heat and the certain hour, the difference of two values is lower than the value set, determines as C.T, when the comparison heat is following for judging the time point of heat supply circular flow again this to be elaborated at Fig. 4 to Fig. 7.
After judging the heat supply circular flow again as above-mentioned multiple condition, utilize the heat supply circular flow of judging again to replenish the supply heat and impel and return coolant-temperature gage and be maintained until and return the water design temperature, stage S360.
Supply with heat such as the additional heat interval shown in Fig. 4 in order to replenish, the supply coolant-temperature gage that utilizes the heat control stage with return coolant-temperature gage discrepancy delta T2 and will supply with the water design temperature and be set at Ref.T2 again, replenish to supply with heat and impel and supply with coolant-temperature gage and be maintained until the supply water design temperature Ref.T2 that sets again, will return coolant-temperature gage and can be maintained until and return water design temperature TR-set.At this moment, can become first heat for judging that the heat supply circular flow is supplied with in the flow judgement stage when returning the supply heat that coolant-temperature gage maintains when returning water design temperature TR-set.
Replenishing of supply heat by the S360 stage, make and return coolant-temperature gage and maintain the state that returns the water design temperature heat supply circular flow that judges no change is arranged, feed back to the follow-up S320 stage, stage S370, S380 behind second heat of when the heat supply circular flow changes, having set according to the variation supply of heat supply circular flow.
