Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making creative efforts based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
Please refer to fig. 1 and fig. 2. An embodiment of the present invention provides a heating temperature control method that is applicable to, but not limited to, heating outlet water temperature control of heating equipment such as a heating stove or a heat pump water heater, and that is also applicable to heating temperature control of heating equipment such as an air conditioner, and the like. Specifically, the heating temperature control method includes the steps of:
s100, acquiring outdoor temperature, indoor actual temperature and indoor set temperature;
s200, determining a basic heating temperature according to the outdoor temperature and the indoor set temperature;
s300, correcting the basic heating temperature according to a temperature difference value of the indoor set temperature and the indoor actual temperature.
According to the heating temperature control method provided by the embodiment, the basic heating temperature is determined firstly through the outdoor temperature and the indoor set temperature, and then the basic heating temperature is corrected according to the temperature difference value of the indoor set temperature and the indoor actual temperature, so that the self-adaption of the actual heating temperature to the outdoor temperature change and the self-adaption of the indoor actual temperature change can be achieved simultaneously, the heating equipment can continuously and stably operate, frequent start and stop of the heating equipment (such as a heating furnace) and large room temperature fluctuation are avoided, and the effect of energy-saving heating is achieved.
In the present embodiment, the heating temperature control method is applied to a heating facility to control the heating temperature of the heating facility (the corrected base heating temperature is used as the actual heating temperature). In other embodiments, the heating temperature control method may be applied to a controller that is externally installed, and the present application is not limited to the embodiment of the heating device or the controller integrated in the heating device.
In step S100, there are various ways to obtain the outdoor temperature, for example, the outdoor temperature may be obtained through external communication, or input by a user, or even obtained through self-detection. In this embodiment, the outdoor temperature may be obtained through a communication module communicating with the outside, or the outdoor temperature may be measured through a temperature sensor.
Specifically, the heating device may be provided with a network communication module, and obtain the outdoor temperature of the area through communication with an external network (e.g., world wide web), and of course, the communication module (e.g., signal receiving module) of the heating device may also communicate with other devices (e.g., mobile phone terminal), and obtain the outdoor temperature by using the other devices. Alternatively, the heating apparatus is provided with a temperature sensor (temperature probe) which directly detects the outdoor temperature.
When the heating equipment is provided with the communication module and the temperature sensor, the priority of acquiring the outdoor temperature by using the temperature sensor is higher than the priority of acquiring the outdoor temperature by using the communication module. That is, in step S100, the outdoor temperature is preferentially acquired by the temperature sensor. When the temperature sensor is damaged (for example, data cannot be acquired or acquired temperature data is obviously abnormal), the communication module is adopted to acquire the outdoor temperature.
In step S100, the actual indoor temperature and the set indoor temperature may be obtained by a thermostat located indoors. The thermostat can communicate with heating equipment and transmit the acquired temperature parameters (indoor actual temperature and indoor set temperature) to (a controller or a control device of) the heating equipment. When a plurality of rooms have heating requirements, the data of the temperature controller of one room can be acquired, or the data of several temperature controllers can be acquired randomly.
In this embodiment, the indoor set temperatures and the indoor actual temperatures of all the thermostats that generate the indoor heating demand are obtained. Wherein, the temperature controller is integrated with a temperature sensor for measuring the actual temperature in the room. The temperature controller is communicated with heating equipment, and the heating equipment can obtain indoor set temperature and indoor actual temperature in the temperature controller at regular time.
In other embodiments, the temperature controller is not limited to acquiring the indoor set temperature and the indoor actual temperature, and for example, the heating device may have a temperature setting module (for example, the temperature setting module includes a temperature input unit input by a remote controller or a button) corresponding to the indoor set temperature of different rooms, and each room having a heating demand may be provided with a temperature sensor for acquiring the indoor actual temperature.
In step S100, the outdoor temperature, the indoor actual temperature, and the indoor set temperature may be acquired at regular time (periodically). The outdoor temperature, the indoor actual temperature and the indoor set temperature can be synchronously obtained according to the same period, and each parameter can also have an independent obtaining period respectively to obtain the outdoor temperature, the indoor actual temperature and the indoor set temperature respectively. In this embodiment, the outdoor temperature, the indoor actual temperature, and the indoor set temperature are periodically acquired and supplied to the subsequent steps, and the heating temperature is dynamically adjusted.
In step S200 of the present embodiment, the base heating temperature may be calculated by using a predetermined formula relating to the outdoor temperature and the indoor set temperature. In the predetermined formula, the base heating temperature is negatively correlated with the outdoor temperature, and the base heating temperature is positively correlated with the indoor set temperature.
For example: the predetermined formula may be a one-dimensional equation of the base heating temperature with the outdoor temperature and the indoor set temperature. Of course, the relevant parameters of the predetermined formula can be individually set according to different regions, the heat preservation condition of the house type of the user's home (based on the outdoor temperature), and the heating preference of the user (for example, based on the temperature of the temperature controller set by the user).
In step S200, the base heating temperature may be determined from the highest indoor set temperature among all the indoor set temperatures. Specifically, after all indoor set temperatures which give out indoor heating demands are obtained, the highest indoor set temperature is determined, and then the basic heating temperature is determined according to the highest indoor set temperature and the outdoor temperature. Of course, in another embodiment, when there are a plurality of indoor set temperatures, the base heating temperature may be determined by an average value of the plurality of indoor set temperatures (average indoor set temperature), and the present application does not limit the maximum indoor set temperature.
In step S200, the dynamic parameters obtained by determining the base heating temperature include only the outdoor temperature and the indoor set temperature, but it is needless to say that the present application does not exclude the case where the base heating temperature also takes into account other dynamic parameters, for example, the base heating temperature is also determined based on the actual indoor temperature.
The base heating temperature is corrected to determine an actual heating temperature in step S300. The heating facility may adjust the combustion power of the burner or the compressor power based on the corrected base heating temperature (actual heating temperature) and perform heating according to the actual heating temperature. In order to prevent the heating capacity of the heating equipment from being exceeded by the unrestricted adjustment of the base heating temperature, the base heating temperature is corrected between the minimum heating temperature and the maximum heating temperature when the base heating temperature is corrected. That is, the actual heating temperature after the base heating temperature correction cannot exceed the maximum heating temperature and cannot be lower than the minimum heating temperature.
In another embodiment, the corrected base heating temperature may be prevented from exceeding the heating capacity of the heating facility by limiting the correction width (adjustment width) of the base heating temperature. Specifically, the correction amplitude of the base heating temperature does not exceed a predetermined threshold. For example, the predetermined threshold may be [ a, B ], accordingly, T1 ═ T2 +. DELTA.t, and a ≦ DELTA.t ≦ B. Here, T1 is the actual heating temperature (corrected base heating temperature), T2 is the base heating temperature, and Δ T is the correction width.
In step S300, a temperature difference between the indoor set temperature and the indoor actual temperature may be determined, and then the base heating temperature may be corrected according to the temperature difference. When there are a plurality of rooms in which the indoor heating demand is generated, there are indoor set temperatures and indoor actual temperatures corresponding to the different rooms. In order to comprehensively consider the regulation of the heating temperature, in step S100, the indoor set temperatures and the indoor actual temperatures of all the temperature controllers which issue the indoor heating demand are obtained. So can acquire a plurality of indoor settlement temperatures and a plurality of indoor actual temperature when there are a plurality of thermostats that send indoor heating demand.
Correspondingly, the basic heating temperature can be corrected according to the temperature data of the room with the maximum temperature difference, so that the actual heating temperature is determined, and the heating requirement of a user is met to the maximum extent. Specifically, step S300 is performed as the following sub-steps: s301, calculating the temperature difference value of all indoor set temperatures compared with the corresponding indoor actual temperatures; s302, determining the maximum temperature difference value in all the temperature difference values; and S303, correcting the basic heating temperature according to the maximum temperature difference.
Of course, in other embodiments, the base heating temperature may be corrected according to the temperature difference between the maximum indoor set temperature and the minimum indoor actual temperature in all the acquired data, or the base heating temperature may be corrected according to the temperature difference between the indoor set temperature of the room having the farthest heating distance from the heating apparatus and the indoor actual temperature, and it can be seen that the temperature difference determination method in step S300 in this application is not unique.
In order to realize the dynamic adjustment of the heating temperature, in the control method, the step of acquiring the temperature, the step of determining the base heating temperature, and the step of correcting the base heating temperature are executed cyclically at predetermined cycles. That is, steps S100 to S300 are periodically performed, the outdoor temperature, the indoor actual temperature, and the indoor set temperature are periodically acquired, and the subsequent steps are performed.
As shown in fig. 2, taking 20 minutes as an example of cycle time, the outdoor temperature, the indoor actual temperature, and the indoor set temperature are obtained every 20 minutes, and after temperature information is obtained each time, the basic heating temperature is determined again and the newly determined basic heating temperature is corrected, so as to achieve the purpose of dynamic adjustment, so that the heating temperature continuously adapts to changes of the outdoor temperature and the indoor actual temperature, frequent start and stop of heating equipment is reduced, and fluctuation of indoor temperature difference is reduced.
In step S300, the base heating temperature determined in step S200 may be corrected according to a preset rule. In this embodiment, in step S300 (the preset rule may include), if the temperature difference is greater than or equal to a first predetermined value (e.g., 5 degrees celsius), the base heating temperature is raised.
In this step, the base heating temperature may be increased by a predetermined value (e.g., 0.5 degrees Celsius, 1 degree Celsius, or 2 degrees Celsius, etc.) to raise the base heating temperature. Further, the base heating temperature is raised at a rate that increases a first predetermined temperature every first predetermined time. This first scheduled time can be the same with cycle time, so, when judging that need promote basic heating temperature at current cycle, then promote basic heating temperature first predetermined temperature (for example 1 degree centigrade, 1.5 degree centigrade, 2 degree centigrade) as actual heating temperature, if still judge that need promote basic heating temperature in next cycle, then continue to promote first predetermined temperature with basic heating temperature, until reaching and need not to promote or promote the range and reach the settlement threshold value.
In one embodiment, in step S300, the base heating temperature is maintained when the temperature difference is greater than or equal to a second predetermined value (e.g., 2 degrees celsius) and less than a first predetermined value (e.g., 5 degrees celsius). Wherein the second predetermined value is less than the first predetermined value, and the difference between the two may be above 2 degrees celsius.
In consideration of the fact that the temperature is constantly changed under the environmental factor, the human factor or the heating factor, the above embodiments may be combined to perform the control in order to realize the dynamic adjustment of the base heating temperature. Illustratively, in the last period, if the maximum temperature difference is greater than the first predetermined value, the base heating temperature is further increased. After the cycle time elapses, when the maximum temperature difference value changes to be between the second predetermined value and the first predetermined value in the current cycle, the base heating temperature is kept unchanged, and the base heating temperature determined in step S200 in the current cycle is directly used as the actual heating temperature for heating.
In one embodiment, in step S300, in the case that the temperature difference is smaller than a second predetermined value (e.g., 2 degrees celsius) and the indoor actual temperature of the current cycle is greater than the indoor actual temperature of the previous cycle, the base heating temperature is decreased. This embodiment may be performed in a case where the actual temperature of the room deviates less from the set temperature and the actual temperature of the room is still increasing, and the base heating temperature is decreased. In the embodiment, whether the room temperature is increased is determined by comparing with the actual indoor temperature of the previous cycle (the actual indoor temperature is the actual indoor temperature of the room corresponding to the adopted temperature difference, for example, the actual indoor temperature of the room with the highest temperature difference) to determine whether the basic heating temperature is reduced, so that the heat provided by heating automatically adapts to the user requirement, the temperature fluctuation range is reduced, and the energy-saving effect is achieved.
In this embodiment, the base heating temperature is lowered at a rate of lowering a second predetermined temperature (e.g., 1 degree celsius) every predetermined second time. Specifically, the second predetermined time may be the same as the cycle time, so that when it is determined in the current cycle that the basic heating temperature needs to be decreased (reduced), the basic heating temperature is decreased by the second predetermined temperature (for example, 1 degree celsius, 1.5 degrees celsius, 2 degrees celsius) to serve as the actual heating temperature, and if it is still determined in the next cycle that the basic heating temperature needs to be decreased, the basic heating temperature is continuously decreased by the second predetermined temperature until the time that the basic heating temperature does not need to be decreased or the decrease amplitude reaches the set threshold value is reached. Preferably, the second predetermined time may be equal to the first predetermined time, and may be equal to the cycle time, and further, the temperature may be periodically lowered or raised.
In another embodiment, in step S300, if the temperature difference is less than a second predetermined value (e.g., 2 degrees celsius) and the temperature difference compared to the previous period is decreased, the base heating temperature is decreased. In the embodiment, whether the actual indoor temperature is increased is determined by judging the temperature difference value of the two periods before and after. If the temperature difference is smaller than the temperature difference of the previous cycle, it is determined that the actual indoor temperature is increasing, and the basic function temperature is decreased.
In one embodiment, in step S300, in the case that the temperature difference is smaller than a second predetermined value, and the temperature difference of the current period compared with the previous period is unchanged or increased, and/or the indoor actual temperature of the current period compared with the previous period is unchanged or decreased, the base heating temperature is kept unchanged. This embodiment may be performed in a case where the actual temperature of the room is less than the set temperature and is already close to the target temperature set by the user, and if the actual temperature of the room is kept constant or decreased (still within the second predetermined value range), the base heating temperature is kept constant, and the user is directly heated according to the base heating temperature.
In the embodiment, whether the room temperature is reduced is determined by comparing with whether the indoor actual temperature of the previous cycle (the indoor actual temperature is the indoor actual temperature of the room corresponding to the adopted temperature difference, for example, the indoor actual temperature of the room with the highest temperature difference) is reduced, and then the basic heating temperature is directly determined as the heating temperature, so that the heat provided by heating automatically adapts to the user requirement, the temperature fluctuation range is reduced, and the energy-saving effect can be achieved.
In one possible embodiment, in step S300, the base heating temperature is increased if the temperature difference is greater than a third predetermined value (e.g., 0.5 degrees celsius, or 1 degree celsius), and the temperature difference of the current period compared to the previous period (the temperature difference of the previous period is reflected as last time in fig. 2) is unchanged or increased, and/or the actual indoor temperature of the current period compared to the previous period is unchanged or decreased. And when the temperature difference is smaller than a third preset value, the indoor actual temperature is considered to reach the indoor set temperature, and the basic heating temperature is kept unchanged.
This embodiment can be carried out in the actual temperature in room apart from user's the settlement temperature above the third predetermined value, and indoor actual temperature is reducing gradually and is becoming cold this moment, can promote basic heating temperature under this kind of condition, guarantees user's heating temperature, ensures user's use and experiences. The third predetermined value may be smaller than the second predetermined value, for example, the difference between the two may be above 1 degree celsius.
The embodiment may be applied together with other embodiments to control the heating temperature, and when the distance from the last adjusted heating temperature (for example, the base heating temperatures of two adjacent cycles are kept unchanged, and thus the actual heating temperature is kept unchanged, which is regarded as not correcting the temperature) exceeds a predetermined time (for example, 30min), at this time, if the temperature difference is greater than a third predetermined value (for example, 1 degree centigrade), and the temperature difference of the current cycle compared with the previous cycle is unchanged or increased, and/or if the actual indoor temperature of the current cycle compared with the previous cycle is unchanged or decreased, the base heating temperature is increased. Of course, the present embodiment can be applied independently to control the heating temperature.
The above embodiments may be implemented independently or in the same embodiment. For ease of understanding, the above step S300 is described in detail in a specific embodiment herein to further facilitate understanding of the present invention.
Take the highest temperature difference of all rooms with heating requirement as an example. And when the highest temperature difference is more than 5 ℃, increasing the basic heating temperature by 1 ℃ to be used as the actual heating temperature. If the highest temperature difference is still greater than 5 ℃ in the next period, the basic heating temperature (for example, the outdoor temperature or the indoor set temperature is changed, and the basic heating temperatures in two adjacent periods can be different) is increased by 1 ℃ continuously, and the heating temperature is dynamically adjusted.
And when the highest temperature difference is less than 5 ℃ and more than 2 ℃, directly taking the basic heating temperature as the actual heating temperature for heating. When the highest temperature difference value is less than 2 ℃, if the indoor actual temperature of the current period of the room corresponding to the highest temperature difference value is increased compared with the indoor actual temperature of the previous period, the basic heating temperature is reduced by 1 ℃ to serve as the actual heating temperature, so that the situation that the indoor actual temperature continues to rise and exceeds the indoor set temperature, the user experience is prevented from being influenced, and the effect of self-adaptive adjustment is achieved.
