Along with the development of science and technology and the improvement of people's standard of living, the heating heat transfer equipment who gathers into water flow signal and carry out temperature control is popularized gradually in people's daily life, and wherein comparatively common this type of heating heat transfer equipment has gas heater.

In the product standard GB6932, a mandatory requirement is made on the stipulation that the water temperature fluctuation is not more than 3 ℃, and the human skin can sense the temperature change amplitude of the product according to scientific research over 1K. Therefore, keeping the outlet water temperature stable and reducing the fluctuation range of the water temperature is one of the core indexes for measuring the quality of a gas water heater.
However, the water flow signal is generally collected and transmitted in the form of an electric wave signal, and the feedback and collection are basically free of time delay. The heat load is adjusted by adjusting the current of the proportional valve and then changing the opening of a gas channel of the proportional valve through the movement of the tympanic membrane, so that the gas inflow is changed, and finally the purpose of adjusting the combustion heat load is achieved. It is clear that there is some hysteresis in the regulation of the thermal load in the operation to achieve the thermal load correction based on the water flow signal. In the actual use process of a gas water heater, the situation that the water inlet pressure fluctuates briefly and then recovers immediately is common, the heat load cannot be synchronous with the water flow change due to the hysteresis of the heat load after the heat load changes, and the fluctuation of the water outlet temperature is further aggravated under the situation.

Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling a heating heat exchanger includes step S300, step S400, and step S500.
And step S300, when the water inlet pressure of the heating heat exchange equipment fluctuates, acquiring the fluctuation duration of the water inlet pressure and the fluctuation value of the water inlet flow caused by the fluctuation of the water inlet pressure.
Specifically, the heating equipment of this embodiment is the heating heat exchange equipment that needs to gather water flow signal and carry out outlet water temperature control, and the equipment of this type is more, for example purifier, gas heater etc. for easy understanding of each embodiment of this application, the heating heat exchange equipment that each embodiment below shows all can understand as gas heater.
In a normal state, the water inlet pressure is in a constant state, and even if the water inlet pressure changes, the change of the water inlet pressure does not exceed a certain threshold interval. Therefore, the water inlet pressure change can mean that the water inlet pressure is considered to be changed when the difference value of the water inlet pressures acquired by two adjacent times is not in the threshold interval. When the water inlet pressure changes, the water flow flowing into the heating heat exchange equipment is often caused to fluctuate, namely, the water inlet flow is caused to fluctuate. Therefore, at the moment, the corresponding water flow fluctuation value can be visually acquired through the parameter acquisition device arranged at the water inlet port of the heating heat exchange equipment. For example, in one embodiment, a flow collector is arranged at a water inlet of the heating heat exchange device, the water inlet flow is collected in real time and sent to a controller for analysis, and when the water inlet flow fluctuates, the water inlet pressure is equivalently considered to fluctuate.
The duration of the fluctuation of the water inlet pressure is the time required for the water inlet pressure to recover to the vicinity of the initial pressure (smaller deviation is allowed) after the fluctuation of the water inlet pressure, and the duration of the fluctuation of the water inlet pressure can be obtained by timing detection of the controller. When the controller acquires the water inlet flow values of the heating heat exchange equipment in real time, each water inlet flow value can record a corresponding acquisition time point, and when a certain water inlet flow value fluctuates relative to the previous water inlet flow value, the time point corresponding to the water inlet flow value is acquired. And then, continuously monitoring the inflow water flow value, and recording the corresponding time point when the inflow water flow value is recovered. Finally, the duration of the fluctuation of the inflow water flow, namely the duration of the fluctuation of the inflow water pressure, can be obtained only by subtracting the two time points.
And step S400, performing comparative analysis according to the duration, the inlet water flow fluctuation value, the preset duration and the preset flow fluctuation value.
Specifically, the controller is pre-stored with a preset duration and a preset flow fluctuation value, and when the water inlet pressure fluctuates and the duration and the water inlet flow fluctuation value are obtained through analysis, the duration and the preset duration are compared and analyzed, and meanwhile, the water inlet flow fluctuation value and the preset flow fluctuation value are compared and analyzed. And reflecting the fluctuation degree of the water inlet pressure in the current state by using the fluctuation duration of the water inlet pressure and the fluctuation value of the water inlet flow caused by the fluctuation of the water inlet pressure, and further determining whether the heat load of the heating heat exchange equipment needs to be adjusted according to a comparison result.
And S500, when the duration is longer than or equal to the preset duration and the inflow fluctuation value is longer than or equal to the preset flow fluctuation value, correcting the heat load of the heating heat exchange equipment.
Specifically, the condition that the duration is longer than or equal to the preset duration indicates that the water pressure fluctuation of the heating heat exchange equipment does not belong to the common situation that the water inlet pressure fluctuates for a short time and then recovers immediately, and the heat load regulation in the state can not cause more severe outlet water temperature fluctuation due to regulation lag. Meanwhile, if the inflow water pressure fluctuation value is larger than or equal to the preset flow fluctuation value, the inflow water pressure fluctuation is larger, the larger inflow water pressure fluctuation can cause larger outflow water temperature fluctuation, and if the thermal load correction is carried out in the state, the correction amount of the thermal load can be used for making up the outflow water temperature fluctuation caused by the inflow water pressure fluctuation, and more severe outflow water temperature fluctuation can not be caused. Therefore, through the scheme of the embodiment, the heat load correction can be carried out under the condition that the water inlet pressure changes greatly, and the condition that the water outlet temperature is fluctuated cannot be aggravated at the moment, so that the comfort level of the domestic water of a user is ensured.
Referring to fig. 2, in an embodiment, after step S400, the method further includes step S600.
And step S600, when the duration is less than the preset duration and/or the inflow fluctuation value is less than the preset fluctuation value, maintaining the heat load of the heating heat exchange equipment unchanged.
Specifically, referring to fig. 3, when the controller performs comparative analysis according to the duration, the intake flow fluctuation value, the preset duration, and the preset flow fluctuation value, at least one of the case where the duration is less than the preset duration and the case where the intake flow fluctuation value is less than the preset flow fluctuation value may occur. Under these conditions, the fluctuation degree of the water inlet pressure is small, and if the heat load is corrected, the fluctuation of the water outlet temperature is further aggravated because the hysteresis of the heat load correction cannot be synchronous with the water flow change. Therefore, if the controller detects that the duration is less than the preset duration and/or the inflow fluctuation value is less than the preset flow fluctuation value, the heat load does not need to be corrected, and only the current heat load needs to be maintained and the automatic recovery of the inflow pressure of the heating heat exchange equipment is waited.
Referring to fig. 4, in an embodiment, before step S300, the method further includes step S100.
And S100, analyzing according to different inflow signals output by the external inflow signal simulator to obtain preset duration and a preset flow fluctuation value.
Specifically, the inflow pressure fluctuates and corresponds to the inflow flow signal, and the inflow flow rate of the inflow pressure changes inevitably, so the present embodiment utilizes the inflow flow signal to realize the setting of the preset duration and the preset flow fluctuation value. The preset duration and the preset flow fluctuation value are not unique, in order to ensure that the preset duration and the preset flow fluctuation value meet the actual working condition of the current heating heat exchange equipment, an inflow water signal simulator is required to be externally connected to a controller of the heating heat exchange equipment and used for simulating and outputting an inflow water signal to the controller, and then the preset duration and the preset flow fluctuation value used for carrying out heat load correction judgment on the heating heat exchange equipment are obtained according to detection results of the inflow water signal in different states.
Further, referring to fig. 5, in an embodiment, step S100 includes step S110 and step S120.
Step S110, when the external inflow water flow signal simulator simulates that the output inflow water flow signal fluctuates and is recovered immediately, the heat load of the heating heat exchange equipment is adjusted to obtain the preset duration; and step S120, when the external inflow water flow signal simulator simulates and outputs the continuous fluctuation of the inflow water flow signal, comparing and analyzing two operation states according to the correction of the heat load of the heating heat exchange equipment along with the inflow water flow signal and the correction of the heat load of the heating equipment without correction, and obtaining a preset flow fluctuation value.
Specifically, the external inflow water flow signal simulator simulates and outputs an inflow water flow signal to fluctuate and immediately recover, namely, the inflow water flow signal simulator sends an inflow water flow signal which fluctuates to the controller, and then sends a normal water flow signal to the controller. Under the action of the fluctuating inflow water flow signal, the controller can immediately correct the heat load of the heating heat exchange equipment, and the corresponding required preset duration can be obtained by collecting the time points of generation or reception of each signal in the process.
Under the other condition, the external inflow water flow signal simulator simulates and continuously outputs a fluctuating inflow water flow signal, the heating heat exchange equipment is processed under two states, one is to adjust the heat load according to the fluctuation of the inflow water flow in real time, the other is to only send a water flow fluctuation signal to the heating heat exchange equipment, the correction is not carried out, and the critical flow fluctuation value corresponding to a high critical flow fluctuation value when the heat load adjustment does not aggravate the outflow water temperature fluctuation is the preset flow fluctuation value.
Further, referring to fig. 6, in an embodiment, step S110 includes step S111, step S112, and step S113.
Step S111, when the external inflow water flow signal simulator simulates that the output inflow water flow signal fluctuates and recovers immediately, recording the fluctuation period of the inflow water flow signal; step S112, acquiring a change cycle of heat load change when the heating equipment adjusts the heat load according to the inflow water flow signal; and step S113, obtaining the lag time of the thermal load regulation according to the fluctuation cycle and the variation cycle, wherein the lag time is the preset duration.
Specifically, the fluctuation period of the inflow water flow signal is the time interval between the inflow water flow and the recovery, and the change period of the thermal load change is the time interval between the thermal load change and the thermal load recovery due to the inflow water flow when the thermal load is adjusted. By subtracting the variation period and the fluctuation period, the corresponding lag time can be obtained.
It is understood that, in one embodiment, in order to ensure the accuracy of the preset duration, the plurality of lag times may be obtained in the manner described in the above embodiment, and then the final preset duration may be obtained by averaging.
Referring to fig. 7 in combination, in one embodiment, step S120 includes step S121 and step S122.
Step S121, when the external inflow water flow signal simulator simulates and outputs an increasing inflow water flow signal, recording a first water temperature fluctuation amount when the heat load is corrected along with the inflow water flow under each inflow water flow signal and a second water temperature fluctuation amount when the heat load is not corrected; and S122, recording a corresponding inflow water flow signal when the first water temperature fluctuation amount is smaller than or equal to the second water temperature fluctuation amount for the first time, wherein the inflow water flow fluctuation value corresponding to the inflow water flow signal is the preset flow fluctuation value.
Specifically, in this embodiment, the inflow signal is gradually increased from small to large (i.e., the inflow or the inflow fluctuation value is gradually increased), the test is performed in groups 2, the group 1 is added with a thermal load correction mechanism, and the group 2 is not corrected. Respectively detecting and recording the fluctuation value of the water outlet temperature under the same water inlet flow signal, finding out the corresponding water inlet flow signal when the fluctuation value of the water outlet temperature of the group 1 is smaller than or equal to the fluctuation value of the water outlet temperature of the group 2 for the first time in the process of gradually increasing the water inlet flow signal through data comparison and analysis, and obtaining the corresponding preset flow fluctuation value according to the water inlet flow signal.
It will be appreciated that in the case of a group 1 with a heat load regulation mechanism, due to the lag time, the fluctuation value of the leaving water temperature will be greater than in the case of a group 2 without heat load correction, in the case of a non-varying entering water flow. Along with the increase of the inflow water flow signal, namely along with the increase of the inflow water flow fluctuation value, the first water temperature fluctuation value is gradually close to the second water temperature fluctuation value, and the corresponding inflow water flow signal is obtained under the critical state that the first water temperature fluctuation value is smaller than or equal to the second water temperature fluctuation value, so that the preset flow fluctuation value can be obtained through analysis.
In a specific embodiment, the scheme may be: setting the long-time continuous fluctuation and fluctuation quantity Q of the inflow water flow signal in different rangesWave motionIs n × QPractice of(0＜n≤20％)，QPractice ofNamely the water flow under the condition that the fluctuation does not occur in the initial state. And the test was performed in two states: the state 1 is that the heat load is corrected in time along with the change of the inflow rate; state 2 is a state in which the thermal load is not changed after setting. Continuously increasing the value of n (namely increasing the inflow water flow) step by step through a plurality of times of fuzzy experiments, detecting the critical value n of the fluctuation amplitude of the water flow signal, and when the actual fluctuation quantity Q isWave motion＜nCritical point of×QPractice ofThe fluctuation range of the water outlet temperature in the state 1 is larger than that in the state 2, and when the actual fluctuation quantity Q isWave motion≥nCritical point of×QPractice ofWill cause the symptomsThe fluctuation range of the outlet water temperature under the state 1 is less than or equal to that under the state 2, and the corresponding preset flow fluctuation value Q is obtained at the momentPreset of＝nCritical point of×QPractice of。
It should be noted that, in order to ensure the detected preset flow fluctuation value QPreset ofThe accuracy of the method is that the increasing amplitude of the n value can be set to be smaller in the process of gradually increasing the inflow. For example, in one embodiment, the value of n is increased by 0.1% each time, i.e. the inflow signal is output by the inflow signal simulator at QPractice ofOn the basis of the (A), sequentially adding 0.1% multiplied by QPractice of、0.2％×QPractice of、0.3％×QPractice of、0.4％×QPractice of… … until a state 1 outlet water temperature fluctuation less than or equal to the state 2 outlet water temperature fluctuation occurs.
Referring to fig. 8, in an embodiment, before step S300, the method further includes step S200.
And S200, acquiring the water inlet flow of the heating heat exchange equipment in real time and analyzing whether the water inlet pressure of the heating heat exchange equipment fluctuates or not.
Specifically, the inlet port of the heating heat exchange equipment is provided with a water inflow collector, and in the process of power-on operation of the heating heat exchange equipment, the pressure collector can collect water inflow in real time and send the collected water inflow to the controller to analyze whether the water inflow fluctuates. Specifically, it may be determined whether the two adjacent water inlet flows are completely consistent, or whether a difference between the two adjacent water inlet flows is within an allowable threshold range, and if the water inlet flow fluctuates, the water inlet pressure is equivalently considered to fluctuate. Through the scheme of this embodiment, can in time learn when pressure of intaking takes place to in the time of water pressure fluctuation is great, can in time adjust the heat load volume.
Referring to fig. 9, in an embodiment, the step of correcting the heat load of the heating heat exchanger includes step S510 and step S520.
Step S510, acquiring and analyzing the current water outlet temperature, the target water outlet temperature and the current water inlet flow to obtain a required heat load correction quantity; and step S520, adjusting the running state of the heat exchange quantity regulator of the heating heat exchange equipment according to the heat load correction quantity.
Specifically, taking a heating heat exchange device as a gas water heater as an example, an outlet water temperature collector is arranged at a water outlet of the gas water heater, an inlet water flow collector is arranged at a water inlet of the gas water heater, during operation of the gas water heater, the outlet water temperature collector and the inlet water flow collector respectively collect current outlet water temperature and current inlet water flow, and in combination with preset target outlet water temperature, a thermal load amount to be corrected is calculated by using a constant temperature algorithm, then a gas valve current value is adjusted to enable a tympanic membrane to move, specifically, the gas proportional valve opening is properly increased or decreased, so that the gas flow can be properly increased or decreased, and the thermal load is corrected.
Adopt the gas heater of the scheme of above-mentioned embodiment, can effectively improve gas heater's temperature controllability, when user's water inlet pipe pressure had undulant, the adaptation that can be better reduced the temperature and undulant, promoted product use comfort.
According to the control method of the heating heat exchange equipment, when the water inlet pressure fluctuates, the heat load is not directly adjusted along with the fluctuation of the water inlet pressure, but the duration time of the fluctuation of the water inlet pressure and the fluctuation value of the water inlet flow caused by the fluctuation of the water inlet pressure are obtained and analyzed with the preset duration time and the preset flow. And only when the duration is longer than or equal to the preset duration and the inflow water fluctuation value is longer than or equal to the preset flow fluctuation value, the heat load is corrected along with the fluctuation of the inflow water pressure. Through the scheme, the heat load can be prevented from being corrected under the condition that the water inlet pressure is recovered after transient fluctuation, so that the phenomenon that the water outlet temperature is fluctuated due to the correction hysteresis of the heat load is avoided.

For specific limitation of the control device of the heating heat exchange device, reference may be made to the above limitation on the control method of the heating heat exchange device, and details are not described herein again.

Referring to fig. 13, a control system for heating heat exchange equipment includes a water inflow collector 20 and a controller 10, wherein the water inflow collector 20 is connected to the controller 10, and the controller 10 is configured to control the heating heat exchange equipment according to the above method.
Specifically, in a normal state, the water inlet pressure is in a constant state, and even if the water inlet pressure changes, the change of the water inlet pressure does not exceed a certain threshold interval. Therefore, the water inlet pressure change can mean that the water inlet pressure is considered to be changed when the difference value of the water inlet pressures acquired by two adjacent times is not in the threshold interval. When the water inlet pressure changes, the water flow flowing into the heating heat exchange equipment is often caused to fluctuate, namely, the water inlet flow is caused to fluctuate. Therefore, at the moment, the corresponding water flow fluctuation value can be visually acquired through the parameter acquisition device arranged at the water inlet port of the heating heat exchange equipment. For example, in one embodiment, a flow collector is disposed at a water inlet of the heating heat exchange device, and collects and sends the inflow water to the controller 10 for analysis, and when the inflow water fluctuates, the inflow water pressure is considered to fluctuate.
The duration of the fluctuation of the water inlet pressure is the time required for recovering the water inlet pressure after the fluctuation of the water inlet pressure, and the duration of the fluctuation of the water inlet pressure can be obtained by timing detection of the controller 10. When the controller 10 acquires the water inlet flow values of the heating heat exchange equipment in real time, each water inlet flow value records a corresponding acquisition time point, and when a certain water inlet flow value fluctuates relative to the previous water inlet flow value, the time point corresponding to the water inlet flow value is acquired. And then, continuously monitoring the inflow water flow value, and recording the corresponding time point when the inflow water flow value is recovered. Finally, the duration of the fluctuation of the inflow water flow, namely the duration of the fluctuation of the inflow water pressure, can be obtained only by subtracting the two time points.
The controller 10 is pre-stored with a preset duration and a preset flow fluctuation value, and after analyzing the duration and the intake flow fluctuation value in the state that the intake pressure fluctuates, the controller 10 will control the duration and perform comparative analysis with the preset duration, and simultaneously perform comparative analysis with the intake flow fluctuation value and the preset flow fluctuation value. And reflecting the fluctuation degree of the water inlet pressure in the current state by using the fluctuation duration of the water inlet pressure and the fluctuation value of the water inlet flow caused by the fluctuation of the water inlet pressure, and further determining whether the heat load of the heating heat exchange equipment needs to be adjusted according to a comparison result.
The duration time is more than or equal to the preset duration time, namely the situation that the water pressure fluctuation of the heating heat exchange equipment is not common 'the water inlet pressure is fluctuated for a short time and then is recovered immediately', and the more severe fluctuation of the water outlet temperature caused by the regulation lag can not be caused by the heat load regulation in the state. Meanwhile, if the inflow water pressure fluctuation value is larger than or equal to the preset flow fluctuation value, the inflow water pressure fluctuation is larger, the larger inflow water pressure fluctuation can cause larger outflow water temperature fluctuation, and if the thermal load correction is carried out in the state, the correction amount of the thermal load can be used for making up the outflow water temperature fluctuation caused by the inflow water pressure fluctuation, and more severe outflow water temperature fluctuation can not be caused. Therefore, through the scheme of the embodiment, the heat load correction can be carried out under the condition that the water inlet pressure changes greatly, and the condition that the water outlet temperature is fluctuated cannot be aggravated at the moment, so that the comfort level of the domestic water of a user is ensured.
In one embodiment, referring to fig. 14 in combination, the control system of the heating heat exchanger further includes an outlet water temperature collector 50. Taking heating heat exchange equipment as a gas water heater as an example, a water outlet temperature collector 50 is arranged at a water outlet of the gas water heater, a water inlet flow collector 20 is arranged at a water inlet in a matching manner, when the gas water heater operates, the water outlet temperature collector 50 and the water inlet flow collector 20 are arranged at the water outlet and respectively collect the current water outlet temperature and the current water inlet flow, the preset target water outlet temperature is combined, the heat load quantity needing to be corrected is calculated by using a constant temperature algorithm, then the gas valve current value is adjusted to enable the tympanic membrane to move, specifically, the opening degree of a gas proportional valve is properly increased or decreased, so that the gas flow can be properly increased or decreased, and the heat load is corrected.
When the water inlet pressure fluctuates, the control system of the heating heat exchange equipment does not directly adjust the heat load along with the fluctuation of the water inlet pressure, but obtains the duration of the fluctuation of the water inlet pressure and the fluctuation value of the water inlet flow caused by the fluctuation of the water inlet pressure, and analyzes the duration and the preset flow. And only when the duration is longer than or equal to the preset duration and the inflow water fluctuation value is longer than or equal to the preset flow fluctuation value, the heat load is corrected along with the fluctuation of the inflow water pressure. Through the scheme, the heat load can be prevented from being corrected under the condition that the water inlet pressure is recovered after transient fluctuation, so that the phenomenon that the water outlet temperature is fluctuated due to the correction hysteresis of the heat load is avoided.
