Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1, an embodiment of the present application provides a method for controlling a water heater, where the method includes:
s10, collecting the current sunshine intensity;
and S20, controlling the working state of the water heater based on the change condition of the current sunshine intensity within the preset time length.
In one embodiment, the water heater may be an air-powered water heater. The air energy water heater can achieve the purpose of heating water by absorbing heat in air. And the unit energy efficiency ratio of the air energy water heater is related to the sunshine intensity parameter of the outdoor unit. The sunshine intensity is low, and the energy efficiency of the unit is poor; the sunshine intensity is strong, and the unit energy efficiency ratio is higher. Outdoor sunshine intensity is high, and consequently outdoor air temperature is higher to can provide the heating efficiency of air energy water heater saves the electric energy. It is understood that the water heater can also be a solar water heater, and the heating efficiency of the solar water heater is also closely related to the sunshine intensity.
In S10, the current temperature is the sunshine intensity at the position of the water heater collected in real time. It can be understood that the air-energy water heater is generally installed indoors, and the light intensity sensor can be arranged outdoors and then connected with the water heater, so that the real-time sunshine intensity signal can be transmitted to the air-energy water heater.
In S20, the preset time period may be set according to the usage environment of the air-source water heater and the model of the water heater. In one embodiment, the preset time may be a half hour. The working state of the water heater can be a heating state, a non-heating state or a standby state. At each preset time length, the sunshine intensity can be increased or decreased along with the change of time.
The embodiment of the application provides a water heater control method, at first gather current sunshine intensity, then control the operating condition of air energy water heater based on the change situation of current sunshine intensity in the time span of predetermineeing. Within the preset time span, when the illumination intensity is increased to a certain degree, the air energy water heater can be controlled to reduce heating or not to heat, and therefore electric energy is saved. When sunshine intensity diminishes to a certain extent, explains that air temperature descends, can control this moment the air can the water heater heating to can keep the temperature at a suitable temperature, the user of being convenient for in time uses.
Referring to fig. 2, in one embodiment, the S20 includes:
s21, if the water heater is not heated, recording the maximum value of the current sunlight intensity;
and S22, if the time length of the current sunshine intensity less than the maximum sunshine intensity exceeds the preset time length, controlling the water heater to start heating, and continuing to execute the step S10.
In S21, the air-source water heater is not heated, that is, the air-source water heater is in a standby state or a shutdown state, and the unit of the air-source water heater is not operated and is not heated by water. Namely, before the air energy water heater heats, the current sunlight intensity can be collected in real time, and the maximum value of the sunlight intensity can be determined from the current sunlight intensity. Before the air can the water heater unheated, if sunshine intensity maximum changes, can update in real time sunshine intensity maximum. At the same time, the previous maximum value of the illumination intensity can be deleted, so that the data storage amount can be reduced.
In S22, for example, if the solar radiation intensity at a certain time is greater than the solar radiation intensity before, and the solar radiation intensity collected after that time is less than the solar radiation intensity at that time, the solar radiation intensity at that time can be defined as the maximum solar radiation intensity for that time period. After the time, if none of the solar intensity exceeds the maximum solar intensity and none of the solar intensity exceeds the maximum solar intensity within the preset time period after the time, the air-source water heater may be controlled to start heating. That is, when the maximum value of the solar radiation intensity is not exceeded within the preset time length after the moment, it indicates that the current solar radiation intensity is at least not increased, and if the state is maintained within the preset time, the energy obtained from the air by the air-energy water heater is reduced. At the moment, the heating function of the air energy water heater is started, so that the water temperature can be maintained at a certain temperature, and a user can conveniently use hot water in time.
In one embodiment, the heating function of the air-energy water heater is turned on again if the solar intensity recorded after that time continuously decreases. It can be further determined that the current air temperature will drop to a greater extent. The air energy water heater can obtain less energy, and the heating function of the air energy water heater needs to be started in time.
In one embodiment, the preset time is half an hour or one hour.
In one embodiment, the step S21 further includes:
and S211, if the time length that the current sunshine intensity is less than the maximum sunshine intensity is less than or equal to the preset time length, clearing the sunshine intensity data recorded in the preset time length after the preset time length, and continuously executing the step S10.
Namely in the preset time, the change of the sunshine intensity is not large, and the influence of the air energy water heater on obtaining energy from the air is not large. Thus, the current state of the air energy water heater can be continuously maintained. And the sunshine intensity data recorded in the preset time length is cleared, so that the occupied space of the data can be reduced.
In one embodiment, before S22, the method includes:
s221, if the current sunshine intensity is smaller than the maximum sunshine intensity, and the difference between the maximum sunshine intensity and the current sunshine intensity is larger than a first threshold value, judging that the current sunshine intensity is smaller than the maximum sunshine intensity.
In this embodiment, numerically, it is first necessary that the current solar intensity be smaller than the previously determined maximum value of the solar intensity. Further, whether the difference between the maximum value of the sunshine intensity and the current sunshine intensity is larger than the first threshold value or not is judged. If the difference between the maximum solar radiation intensity and the current solar radiation intensity is greater than the first threshold, it may be determined that the front solar radiation intensity is less than the maximum solar radiation intensity, and the determination of step S22 may be performed. It is to be understood that the first threshold may be an absolute value. The first threshold value may be obtained from empirical values. If the current sunshine intensity is smaller than the maximum value of the sunshine intensity, the current sunshine intensity can not be directly judged to be obviously reduced, and the energy obtained from the air by the air energy water heater is greatly influenced. When the difference between the maximum value of the solar intensity and the current solar intensity is greater than the first threshold value, it is indicated that the solar intensity has decreased to a degree that affects the energy efficiency that the air-powered water heater obtains from the air. Therefore, when the difference between the maximum value of the sunshine intensity and the current sunshine intensity is greater than a first threshold value, the current sunshine intensity is determined to be smaller than the maximum value of the sunshine intensity, and the time when the air energy water heater starts to heat can be accurately judged.
Referring to fig. 3, in one embodiment, the S20 includes:
s23, if the water heater starts to heat, recording the minimum value of the current sunlight intensity;
and S24, if the time length of the current sunshine intensity greater than the minimum sunshine intensity exceeds the preset time length, controlling the water heater to stop heating, and continuing to execute the step S10.
And S23, when the air energy water heater starts to heat, recording the minimum value of the current sunlight intensity in real time.
In S24, when the solar radiation intensity at a certain time after the air-energy water heater starts heating is less than the previous solar radiation intensity, and the solar radiation intensities collected after the certain time are greater than the solar radiation intensity at the certain time, the solar radiation intensity at the certain time may be defined as the minimum solar radiation intensity value in the time zone. After the time, if none of the solar intensity is less than the solar intensity minimum value and none of the solar intensity within the preset time length after the time is less than the solar intensity minimum value, the air-energy water heater may be controlled to stop heating. That is, when the sunshine intensity data collected within the preset time length after the moment are all smaller than the minimum value of the sunshine intensity, the current sunshine intensity is in a steady rising state, and if the state is maintained within the preset time, the energy obtained by the air energy water heater from the air is increased with a high probability. At the moment, the heating function of the air energy water heater is turned off, so that the purpose of saving energy can be achieved.
In one embodiment, the heating function of the air-energy water heater is turned off again if the solar intensity recorded after that time continues to rise. It can be further determined that the current air temperature will rise to a greater extent. The energy that the air-source water heater can acquire will increase, and the heating function of the air-source water heater can be turned off at this time.
In one embodiment, the step after S23 further includes:
and S231, if the time length that the current sunshine intensity is greater than the minimum sunshine intensity is less than or equal to the preset time length, clearing sunshine intensity data recorded in the preset time length after the preset time length, and continuing to execute the step S10.
That is in the preset time, the change of sunshine intensity is not big, just sunshine intensity is in probably decline rapidly in the preset time, it is great to the influence that air energy water heater reacquires the energy from the air, still need to continue to maintain the state that air energy water heater heated. Thus, the current state of the air energy water heater can be continuously maintained. By clearing the sunshine intensity data recorded within the preset time length, the occupied space of the data can be reduced, and the step S10 can be continuously and circularly executed to acquire the current sunshine intensity.
In one embodiment, before S24, the method includes:
and S241, if the current sunshine intensity is greater than the minimum sunshine intensity and the difference between the current sunshine intensity and the minimum sunshine intensity is greater than a second threshold value, judging that the current sunshine intensity is greater than the minimum sunshine intensity.
In this embodiment, numerically, it is first necessary that the current solar intensity be greater than the previously determined minimum value of the solar intensity. And further, judging whether the difference between the current sunshine intensity and the minimum value of the sunshine intensity is greater than the second threshold value. If the difference between the current solar intensity and the minimum solar intensity is greater than the second threshold value, it can be determined that the front solar intensity is greater than the minimum solar intensity, and then the next step can be performed. It is to be understood that the second threshold may be an absolute value. The second threshold value may be obtained from empirical values. If the current sunlight intensity is greater than the minimum sunlight intensity value, the current sunlight intensity cannot be directly judged to be obviously enhanced. When the difference between the sunshine intensity minimum value and the current sunshine intensity is greater than the second threshold value, the sunshine intensity is explained to be capable of enabling the air temperature to be high enough, and more energy can be provided for the air energy water heater. Therefore, the difference between the sunshine intensity minimum value and the current sunshine intensity is set to be greater than the second threshold value, the current sunshine intensity is determined to be greater than the sunshine intensity minimum value, and the time when the air energy water heater stops heating can be accurately judged.
In one embodiment, the first threshold and the second threshold may be equal or different. The first threshold value and the second threshold value may be set based on empirical values.
In one embodiment, before the S10, the method further includes:
and S010, starting a timing function of the water heater.
Namely, after the water heater is started to have the timing function, the water heater can run the program of the steps. The energy waste caused by the steps when the water heater is powered off can be avoided. And can also be set by the user according to the needs.
Referring to fig. 4, the embodiment of the present application further provides a water heater control device 10. The water heater control device 10 includes an acquisition module 110 and a control module 120.
The collection module 110 is used for collecting the current sunshine intensity. And the current temperature is the sunshine intensity of the position of the water heater in real time. The collection module 110 may be a light intensity sensor disposed outdoors.
The control module 120 is configured to control the operating state of the water heater based on the change of the current sunshine intensity within a preset time period.
In one embodiment, the control module 120 is configured to record a maximum value of a current solar intensity if the water heater is not heated, and control the water heater to start heating if a time length during which the current solar intensity is less than the maximum value of the solar intensity exceeds the preset time length. The preset time length can be set according to the service environment of the air energy water heater and the model of the water heater. The working state of the water heater can be a heating state, a non-heating state or a standby state. At each preset time length, the sunshine intensity can be increased or decreased along with the change of time.
