Abstract
Description
Technical Field
[0001] The present application relates to the technical field of water heaters, and in particular to a control method, system, device and storage medium for an air-energy water heater. Background Art
[0002] Nowadays, the technology of integrated air-energy water heaters continues to mature, and its application scenarios are increasing, and it has become a common household appliance in people's daily life.
[0003] Compared with traditional electric water heaters and gas water heaters that obtain heat energy by consuming gas and electricity, the integrated air-energy water heater uses appropriate electricity to drive the compressor to work. After the high-pressure liquid refrigerant passes through the throttling device such as the electronic expansion valve, it absorbs heat energy from the air in the evaporator and evaporates into gas. The gaseous refrigerant is compressed by the compressor into a high-temperature and high-pressure liquid, which circulates to the water tank for heat exchange. This cycle is repeated to heat the cold water to the temperature we want. While consuming the same amount of electricity, the air-energy water heater can absorb heat energy equivalent to about three times the electricity, that is, to heat the same amount of hot water, the air-energy water heater saves two-thirds of electricity compared to traditional water heaters.
[0004] In the related art, integrated air-energy water heaters are used in multiple scenarios. Generally, integrated air-energy water heaters have larger water tanks than traditional water heaters, and because they continuously use the heat in the air for conversion, the heating time of the air-energy water heater is relatively long. When users use hot water, they need to wait or turn on the water heater in advance for heating. This leads to the common situation of excess heat in integrated air-energy water heaters, which leads to increased energy consumption of integrated air-energy water heaters. Therefore, it is recognized that there are technical problems that need to be solved in the related art. Summary of the invention

[0042] The specific calculation principle of this application is explained below with reference to the accompanying drawings: See also Figure 2 This is the basic working principle of the air-energy water heater. Cold water enters the water tank of the water heater from the cold water inlet at the bottom. After being heated internally, the hot water is in the upper layer and flows out from the upper hot water outlet. It is then diverted to different hot water terminals and applied to different scenarios. By adding sensors at the outlet of the water heater, the time period when the customer uses hot water, the flow rate and temperature of the hot water are collected, and the customer's water demand habits are recorded.
[0043] See also Figure 3 On the first day when the customer starts the air-energy water heater, the continuous heating state is turned on by default to ensure that the user has hot water available 24 hours a day, greatly reducing the need for users to wait for hot water, and then start recording the 24-hour usage status of the air-energy water heater. Figure 4 According to the user's hot water demand in the last 24 hours, the different time periods for opening the air energy water heater in the next 24 hours can be calculated. Human life activities are cyclical, and the demand for hot water is also cyclical.
[0044] In the first 7 days, when the demand for hot water is less than the maximum volume of the water tank, the heating time to meet the hot water demand in the nth period in the last 24 hours is:
[0045] T o Indicates the water temperature at the hot water outlet detected by the sensor on that day.
[0046] T i Indicates the water temperature at the cold water inlet detected by the sensor on that day.
[0047] c represents the specific heat capacity of water, which is 4.2×10 3 J / (kg*℃).
[0048] ρ represents the density of water.
[0049] T n B n Indicates the start time of the nth hot water usage period on the nth day. For example, T2B3 indicates the start time of the second hot water usage period on the third day.
[0050] T n E n Indicates the end time of the nth segment of hot water usage time on the nth day. For example, T3E5 indicates the end time of the 3rd segment of hot water usage time on the 5th day.
[0051] V(t) represents the hot water flow rate collected at the hot water outlet.
[0052] P 常 It indicates the actual heating power of the air-energy water heater when only the compressor is turned on for heating.
[0053] T n H （n+1） It indicates the time required to start the air-energy water heater for normal heating to meet the hot water demand predicted in the nth period of the (n+1)th day.
[0054] T (n+1) H (n+1) It can also be obtained by the above formula, if T (n+1) H (n+1) ≥T (n+1) B n -T n B n , indicating that the demand for hot water during the (n+1)th water usage period on the nth day is much greater than the demand for hot water during the nth water usage period on the nth day, so we do not need to shut down the air-energy water heater during the interval between the two hot water usage periods, and we need to keep the compressor working continuously. At this time, the start time of the air-energy water heater during the nth period on the (n+1)th day is set to:
[0055] In this way, the air-energy water heater can meet the needs of multiple stages of hot water use while avoiding excessive heat waste.
[0056] If T (n+1) H (n+1) <T (n+1) B n -T n B n , and T (n+1) B n -T n E n <30min, in order to avoid frequent start and stop of the compressor, the start time of the air energy water heater in the nth section of the (n+1)th day is set as:
[0057] In other cases, the start time of the air energy water heater in the nth section on the (n+1)th day is:
[0058] If the hot water storage is lower than the customer's demand during use, the user needs to manually turn on the electric heating mode to participate in heating to ensure that the hot water demand is met. This hot water demand will also be recorded.
[0059] See also Figure 5 When n>7, we have completed the record of users' hot water demand habits in the first small cycle and established the water use model for the first week. In the following time period, we can use the water demand collected in the previous small cycle to predict the water demand in the next cycle.
[0060]
[0061] T (n+1) H (n+1) It can also be obtained by the above formula, if T （n+1） H n ≥T (n+1) B （n-7） -T n B (n-7) , indicating that the predicted hot water demand for the (n+1)th water usage time on the nth day is much greater than the predicted hot water demand for the nth water usage time on the nth day, so we do not need to shut down the air-energy water heater during the interval between the two hot water usage times, and we need to keep the compressor working continuously. At this time, the start time of the air-energy water heater on the nth day and the nth period is set to:
[0062] In this way, the air-energy water heater can meet the needs of multiple stages of hot water use while avoiding excessive heat waste.
[0063] If T n H n <T (n+1) B （n-7） -T n B (n-7) , and T (n+1) B (n-7) -T n E (n-7) <30min, in order to avoid frequent start and stop of the compressor, the start time of the nth section of the nth day of the air energy water heater is set as:
[0064] The start time of the air energy water heater in the nth period of the nth day under other circumstances
[0065] If the hot water storage is lower than the customer's demand during use, the user needs to manually turn on the electric heating mode to participate in heating to ensure that the hot water demand is met. This hot water demand will also be recorded.
[0066] See also Figure 6 After recording 4 small cycles, that is, n>28, we obtained the user's water usage model within 4 weeks. For the sudden large demand for water on Monday of the second week, and the large demand for heating in advance on Monday of the third week, if the number of occurrences in 4 consecutive weeks is less than or equal to 2 times, the second largest demand for water is identified as a temporary demand, and the advance heating of the predicted demand will not be performed in the next cycle to avoid a large amount of heat waste.
[0067] If the user really needs a large amount of hot water, he can remotely control the air-energy water heater to heat the water in advance.
[0068] Through this intelligent control system, a user's water use model is established and the model is continuously revised. It can predict the user's water use time and water demand during regular periods, thereby achieving advance heating, reducing the frequent start and stop of the compressor and the use of the more power-consuming electric heating mode, reducing the user's waiting time for hot water, and avoiding the heat waste of a large amount of hot water remaining in the water tank after the user uses the hot water, thereby further improving user satisfaction.

[0071] The second processing unit 1002 is used to determine the first heating time of the air-energy water heater required to be turned on to meet the hot water demand predicted in the nth period of the n+1th day based on the first water temperature, the second water temperature, the first hot water flow rate, the first start time and the first end time.
