And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the heat pump water heater control method of the present invention is described in conjunction with a heat pump water heater, this is not limiting, and other devices having a heat pump heating requirement may be configured with the heat pump water heater control method of the present invention, such as a heat pump heater device.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The terms referred to in this application are explained first:
1) the heat pump water heater is also called as an air energy water heater or an air source heat pump water heater. The heat pump water heater absorbs low-temperature heat in air, gasifies a fluorine medium, is compressed by a compressor, is pressurized and heated, is converted by a heat exchanger to supply water for heating, and heats water temperature by the compressed high-temperature heat energy. Because the air energy water heater works by medium heat exchange, an electric heating element is not required to be in direct contact with water, the electric leakage danger of the electric water heater is avoided, the possible explosion and poisoning dangers of the gas water heater are also prevented, and the air pollution caused by the exhaust gas discharged by the gas water heater is more effectively controlled.

"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
3) "correspond" may refer to an association or binding relationship, and a corresponds to B refers to an association or binding relationship between a and B.
The following explains an application scenario of the embodiment of the present application:
fig. 1 is an application scene diagram of a control method of a heat pump water heater according to an embodiment of the present application, and as shown in fig. 1, the working principle of the heat pump water heater is that heat in air is transferred into water through a refrigerant, which is equivalent to a reverse process of refrigeration of a refrigerator and an air conditioner, refrigerant vapor enters a water tank after being heated by a heat pump, and the heat is released into the water to heat water temperature. The heat pump water heater works according to the principle of 'reverse Carnot cycle', specifically, an outdoor unit is used as a heat exchanger to absorb heat from outdoor air, heat a low-boiling point working medium (refrigerant) and evaporate the low-boiling point working medium, refrigerant steam is compressed by a compressor to raise the temperature and enters a water tank, heat is released to water in the water tank and is condensed and liquefied, and then the water tank is throttled, depressurized and cooled to return to the outdoor heat exchanger to enter the next cycle. Simply speaking, the heat in the air is absorbed to heat the water temperature.
Heat pump water heaters have operating temperature limitations, such as 0-40 degrees celsius. Above this temperature range, and particularly below this temperature range, heat pump water heaters tend to be difficult to operate properly. Because the heat pump actually transfers the external temperature to the water tank according to the working principle of the heat pump, so as to achieve the purpose of heating the water in the water tank, when the external environment temperature is lower, the difficulty of the heat pump for transferring the temperature is higher, namely the working efficiency is lower. In the prior art, when water in the water tank is heated, the water is often determined according to the temperature of the water in the water tank, and the influence of the external environment temperature on the heating efficiency of the heat pump water heater is not considered, so that the problems that the heating efficiency of the heat pump water heater is reduced and the heating effect is influenced are caused.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a heat pump water heater control method according to an embodiment of the present application, and is applied to a heat pump water heater, as shown in fig. 2, the heat pump water heater control method according to the present embodiment includes the following steps:
step S101, acquiring preset predicted temperature information.
Specifically, the predicted temperature information may be information for predicting a change over time in a temperature value in an environment in which an outdoor unit of the heat pump water heater is located. For example, in the environment where the outdoor unit of the heat pump water heater is located, at 8 am, the predicted value of the ambient temperature is 20 degrees celsius; at 12 noon, the predicted value of the environmental temperature is 26 ℃; at 4 pm, the predicted ambient temperature is 22 degrees celsius. The predicted temperature information may be obtained in various ways, for example, according to the change of the temperature value of the previous day with time, the predicted temperature information of the next day is determined; for another example, the predicted temperature information of the next day is determined according to the change of the temperature values of the previous three days along with the time. When the predicted temperature information is determined by the temperature data of a plurality of days, the predicted temperature information can be determined by performing weighted calculation on the temperature data of the plurality of days. Specifically, for example, the average value is calculated according to the change of the temperature values of the last three days with time, and the change of the environmental temperature values with time in the last three days is obtained. Here, the specific implementation method of the predicted temperature information may be determined as needed, and is not limited herein.
In one possible implementation, the preset predicted temperature information is stored in a storage medium in the heat pump water heater, and the heat pump water heater directly reads the predicted temperature information in the storage medium, and in another possible implementation, the preset predicted temperature information is stored in a storage medium outside the heat pump water heater, for example, a cloud server. The heat pump water heater is in communication connection with the cloud server, and predicted temperature information in the storage medium is read from the external cloud server in a wireless communication mode.
Specifically, the preset predicted temperature information may be preset in a storage medium inside or outside the heat pump water heater after being obtained by a user through an experiment or the like, or may be obtained by acquiring information of ambient temperature, humidity, wind power and the like through a sensor unit provided in the heat pump water heater, and performing calculation, where the preset predicted temperature information is not particularly limited.
And step S102, heating the heat pump at the predicted time point according to the predicted temperature information.
Wherein the predicted time points are used to characterize the time nodes at which the daily maximum ambient temperature occurs. Specifically, the predicted temperature information can predict the change of the daily ambient temperature along with time, and the ambient temperature changes along with the rise and fall of the day in the middle of a day, and generally reaches the highest value of the daily temperature between 1-3 noon every day; meanwhile, the lowest value of the daily temperature is reached between 2 and 6 am every day. However, with the change of seasons and the difference of longitude and latitude of various places, the maximum temperature occurrence time point of each day cannot be accurately predicted by using the basic daily rising and falling rule. And the predicted temperature information is obtained according to the ambient temperature of the heat pump water heater. For example, the predicted temperature information is determined according to the temperature change conditions of the last three days in the environment where the heat pump water heater is located, so that the predicted temperature information is matched with the real environment temperature corresponding to the heat pump water heater, and the time point of the occurrence of the highest temperature of each day can be more accurately predicted according to the temperature change conditions of the last three days of the heat pump water heater. Furthermore, the heat pump is heated at the predicted time point, so that the working efficiency of the heat pump can be improved, the heating effect in the water heater can be improved, and the resources can be saved.
In the embodiment, preset predicted temperature information is obtained; according to the predicted temperature information, heating the heat pump at the predicted time point, wherein the predicted time point is used for representing the time node of the highest daily ambient temperature, and the predicted time point corresponding to the predicted temperature information can represent the time node of the highest daily ambient temperature, so that the heat pump is heated at the predicted time point, the ambient temperature of the heat pump can be the highest, the working efficiency of the heat pump is further improved, and the overall heating efficiency and the heating effect of the heat pump water heater are improved.
Fig. 3 is a flowchart of a heat pump water heater control method according to another embodiment of the present application, and as shown in fig. 3, the heat pump water heater control method according to the present embodiment further refines step S101 and step S102 on the basis of the heat pump water heater control method according to the embodiment shown in fig. 2, and adds a step of determining predicted temperature information before S101, and then the heat pump water heater control method according to the present embodiment includes the following steps:
in step S201, ambient temperature history information is acquired.
Specifically, the ambient temperature history information may be ambient temperature data within a previously preset time period, for example, temperature data within three days; temperature data over one month. The historical ambient temperature information can be obtained by acquiring ambient temperature through a sensor arranged on the heat pump water heater; or may be obtained from an external sensor or other data source, and is not particularly limited herein.
Step S202, an environment temperature model is determined according to the environment temperature historical information, wherein the environment temperature model is used for representing the characteristics of the environment temperature changing along with the time.
In one possible implementation, the historical ambient temperature information is indicative of temperature changes over time in the environment of the heat pump water heater. The heat pump water heater is used for an external machine exchanging heat with the outside, the set positions are different, the ambient temperature is different, the historical ambient temperature information is matched with the corresponding heat pump water heater, and the temperature condition of the environment where the heat pump water heater is located can be better represented. According to the historical information of the environment temperature, the temperature change of the environment where the heat pump water heater is located is subjected to feature extraction, and a corresponding environment temperature model can be obtained.
In one possible implementation, the ambient temperature history information includes weather information. The weather information is, for example, information for describing weather conditions, such as precipitation information, air humidity information, wind power information, and the like. Classifying the historical ambient temperature information according to the weather information in the historical ambient temperature information to obtain at least one historical ambient temperature information corresponding to the weather information, and determining at least one model of the ambient temperature corresponding to the weather information according to the at least one historical ambient temperature information corresponding to the weather information.
Specifically, for example, the ambient temperature history information under a weather condition with precipitation is classified into one type; classifying the historical information of the environmental temperature with wind power of more than 5 grades into one class; and respectively extracting the characteristics of the historical ambient temperature information of each category to obtain an ambient temperature model corresponding to the weather information one by one.
In this embodiment, the ambient temperature model corresponding to the weather information refers to the influence of the weather conditions, so that the occurrence conditions of the highest temperature under different weather conditions can be better represented, the position of the predicted time point can be more accurately predicted, and the working efficiency of the heat pump water heater can be improved.
Step S203, determining the predicted temperature information according to the environment temperature model.
The environment temperature model can describe the temperature change characteristics of the environment where the heat pump water heater is located, so that the position where the highest temperature occurs in the environment where the heat pump water heater is located can be determined according to the environment temperature module.
Optionally, as shown in fig. 4, step S203 includes two specific implementation steps S2031 and S2032:
step S2031, according to the environment temperature model, determining the time characteristic that the maximum value of the environment temperature appears in one day in the preset time length.
Step S2032, according to the time characteristics, determining predicted time information, wherein the predicted time information is used for representing a predicted time point of the maximum value of the environmental temperature appearing in one day.
In a possible implementation manner, according to the environment temperature model, the change of the environment temperature in one day is divided into a plurality of preset time periods, more specifically, for example, 12 time periods, each time period is two hours, and the average value of the temperature in each time period is the temperature value corresponding to the time period. The time period corresponding to the maximum temperature value is the time characteristic of the maximum ambient temperature value occurring in one day.
In order to eliminate the influence of the occasional factors and improve the stability of the time characteristics, the time characteristics corresponding to the environment temperature models for multiple days may be superimposed, for example, the time characteristics corresponding to the environment temperature models for the three days before the current date are superimposed to obtain the superimposed time characteristics, and according to the superimposed time characteristics, a time node or a time period where the maximum value of the environment temperature occurs in the three days, that is, the predicted time information is determined.
Step S204, heating the heat pump with first preset power within a first time range of a prediction time point according to the acquired weather information and the prediction temperature information; and heating the heat pump at a second preset power outside the first time range of the predicted time point.
After the predicted time information is determined, the heat pump can be heated according to the predicted time information because the predicted time information corresponds to the time point of the highest ambient temperature, so that the best working efficiency of the heat pump in the same day is achieved. The first preset power is larger than the second preset power. When the time period corresponding to the predicted time information is within a first time range, the heat pump is heated by using first preset power, so that the heat pump can efficiently and quickly heat the water temperature in the water heater; when the time period corresponding to the predicted time information is out, namely the first time range is out, the working efficiency of the heat pump is not high, at the moment, the heat pump works at low power, and the heat preservation effect is achieved on the water temperature in the water heater, for example, the heat preservation effect is used for keeping the water temperature in the water heater at 40-45 ℃. In the step of the embodiment, the heat pump is heated in a segmented manner, and high-power heating is used in a first time range with high heating efficiency of the heat pump, so that the water temperature is rapidly increased; outside a first time range with low heating efficiency of the heat pump, heating with low power is used to keep the water temperature; the comprehensive heating and heat preservation efficiency of the heat pump water heater is improved, the electric energy consumption is reduced, and the cost is saved.
In one possible implementation, the first time range and/or the first predetermined power and/or the second predetermined power are adjusted according to weather information before the heat pump is heated at the first predetermined power or the second predetermined power. Specifically, the weather information includes: at least one of precipitation information, air humidity information and wind power information. The weather information may be obtained by a chip or module provided in the heat pump water heater, and is not particularly limited herein.
Because under the weather condition of difference, the efficiency that the heat pump carries out the heat exchange with the external world can receive the influence, for example, when wind-force is great, can improve heat pump and external heat transfer mouthful department circulation of air speed, consequently can improve heat exchange efficiency, at this moment, even ambient temperature does not reach the highest temperature point of this day, nevertheless because the influence of weather condition, the heat exchange efficiency who makes the heat pump has reached higher level, consequently, heats the heat pump at this moment, can obtain higher heating efficiency. Namely, according to the wind power information in the weather information, the first time range and the first preset power are adjusted to improve the comprehensive working efficiency of the heat pump.
Of course, it can be understood that the above example is only for explaining a principle of how to adjust the first preset power, the second preset power, and the first time range according to the weather information, and in actual operation, the first preset power, the second preset power, and the first time range may be set according to specific needs, and details are not described here.

and the heating module 32 is used for heating the heat pump at a predicted time point according to the predicted temperature information, wherein the predicted time point is used for representing a time node of the occurrence of the highest daily ambient temperature.
