In this embodiment, the second preset water temperature is 30 ℃, that is, the water temperature in the second water tank 200 is continuously maintained at 30 ℃, but in other embodiments, the second preset water temperature may be other temperature values such as 25 ℃ or 35 ℃.
Alternatively, as shown in fig. 1, when the second sensor 250 detects that the amount of water stored in the second water tank 200 is less than a second preset amount of water, the water replenishing mode of the second water tank 200 is started, at this time, the water replenishing valve 410 and the second water inlet valve 231 are opened and the water pump 500 is started, so that the tap water enters the water heater 300 to be heated, and then the second water tank 200 is replenished until the amount of water in the second water tank 200 reaches the second preset amount of water, and the water replenishing valve 410, the second water inlet valve 231 and the water pump 500 are closed, so as to replenish water in the second water tank 200.
It should be noted that, when the water replenishing mode of the second water tank 200 is started, the water outlet temperature of the water heater 300 may be equal to or slightly lower than the second preset water temperature, and if the water outlet temperature of the water heater 300 is equal to the second preset water temperature, the water heater 300 continues to replenish water to the second water tank 200 until the water amount in the second water tank 200 reaches the second preset water amount, and then the water replenishing mode of the second water tank 200 is stopped; if the outlet water temperature of the water heater 300 is lower than the second preset water temperature, the heating mode of the second water tank 200 is started after the water replenishing mode of the second water tank 200 is stopped, and the heating mode of the second water tank 200 is stopped until the water temperature in the second water tank 200 reaches the second preset water temperature.
Preferably, in the water replenishing mode of the first water tank 100, the water flow rate of the water pump 500 (i.e., the water flow rate from the water heater 300 into the first water tank 100) is a first flow rate, in the heating mode of the first water tank 100, the water flow rate of the water pump 500 (i.e., the water flow rate from the water heater 300 into the first water tank 100) is a second flow rate, the first flow rate is smaller than the second flow rate, the water flow rate of the water pump 500 is reduced, the heating time of water in the water heater 300 can be prolonged, the water outlet temperature of the water heater 300 is further increased, in the water replenishing mode of the first water tank 100, the water outlet temperature of the water heater 300 is as close to a first preset water temperature as possible, the probability of starting the heating mode of the first water tank 100 after the water is replenished in the first water tank 100 is reduced, not only can the energy consumption of the water heater 300 caused by the water replenishing in the first water tank 100 be reduced, but also the time period of waiting for the water temperature in the first water tank 100 to reach the first preset water temperature after the water replenishing is shortened, this is important for the first water tank 100 for supplying bath water, and can greatly reduce waiting time when a plurality of people take a bath in a concentrated time period. Similarly, when the second water tank 200 is in the heating mode, the water outlet flow of the water pump 500 (i.e., the water flow from the water heater 300 into the second water tank 200) is the third flow, and when the second water tank 200 is in the water replenishing mode, the water outlet flow of the water pump 500 (i.e., the water flow from the water heater 300 into the second water tank 200) is the fourth flow, and the fourth flow is smaller than the third flow, so that when the second water tank 200 is in the water replenishing mode, the water outlet temperature of the water heater 300 is as close as possible to the second preset water temperature, the probability that the heating mode of the second water tank 200 is started after the water is replenished in the second water tank 200 is reduced, not only can the energy consumption of the water heater 300 caused by the water replenishing of the second water tank 200 be reduced, but also the duration of waiting for the water temperature in the second water tank 200 to reach the second preset water temperature after the water replenishing in the second water tank 200 is shortened.
Alternatively, the first flow rate is less than the third flow rate and the fourth flow rate is less than the second flow rate, i.e., the flow rate of the water pump 500 in the water replenishing mode of the first tank 100 is less than the flow rate of the water pump 500 in the heating mode of the second tank 200, and the flow rate of the water pump 500 in the water replenishing mode of the second tank 200 is less than the flow rate of the water pump 500 in the heating mode of the first tank 100. The first flow rate and the fourth flow rate may be equal to or different from each other, and the second flow rate and the third flow rate may be equal to or different from each other, and may be set according to the use situation.
Alternatively, when the first water tank 100 is in the water replenishing mode, the heating power of the water heater 300 is the first power, when the first water tank 100 is in the heating mode, the heating power of the water heater 300 is the second power, when the second water tank 200 is in the heating mode, the heating power of the water heater 300 is the third power, and when the second water tank 200 is in the water replenishing mode, the heating power of the water heater 300 is the fourth power, both the first power and the second power are greater than the third power, since the first water tank 100 is used for supplying bath water and heating water, and the second water tank 200 is used for supplying kitchen water and domestic water, from the viewpoint of use demand, people can accept lower water temperatures when using the kitchen water and the domestic water, that is, the water temperature in the second water tank 200 can be normally used without reaching the second preset water temperature, so that in actual use, the water heater system can be allowed to heat the water in the second water tank 200 to the second preset water temperature for a longer time, however, when people use bath water and heating water, the requirement for the water temperature is high, that is, the water temperature in the first water tank 100 cannot be used normally when not reaching the first preset water temperature, so that in actual use, the water heater system cannot be allowed to heat the water temperature in the first water tank 100 to the first preset water temperature for a long time, in this embodiment, the power of the water heater 300 in the water replenishing mode of the first water tank 100 and the heating mode of the first water tank 100 is greater than the power of the water heater 300 in the heating mode of the second water tank 200, so that the water temperature in the first water tank 100 can reach the first preset water temperature quickly without affecting the normal use of bath water and heating water, and meanwhile, the heating mode of the second water tank 200 adopts lower heating power, so that on the basis of not affecting the normal use of kitchen water and domestic water, the energy consumption of the water heater 300 can be reduced, the effect of saving energy is achieved.
Further, the fourth power is greater than the third power, that is, the heating power of the water heater 300 in the water replenishing mode of the second water tank 200 is greater than the heating power of the water heater 300 in the heating mode of the second water tank 200, and since the water temperature in the second water tank 200 is higher than the water temperature of the tap water, the heat energy required in the water replenishing mode of the second water tank 200 (that is, the heat energy required to raise the temperature of the tap water to the second preset water temperature) is higher than the heat energy required in the heating mode of the second water tank 200 (that is, the heat energy required to raise the temperature of the water in the second water tank 200 to the second preset water temperature), so that the power of the water heater 300 in the water replenishing mode of the second water tank 200 is greater than the power of the water heater 300 in the water replenishing mode of the second water tank 200, and the effect of shortening the time required for the water temperature in the second water tank 200 to reach the second preset water temperature can be achieved.
Alternatively, the volume of the first tank 100 is smaller than the volume of the second tank 200, and then the first predetermined water amount is smaller than the second predetermined water amount, and when the first tank 100 is refilled, the time for the water temperature in the first tank 100 to reach the first predetermined water temperature is shorter than the time for the water temperature in the second tank 200 to reach the second predetermined water temperature when the second tank 200 is refilled, which further shortens the time for waiting for bathing for the first tank 100 supplying water for bathing.
Alternatively, when the first water tank 100 supplies heating water, the water temperature in the first water tank 100 is heating water temperature, and when the first water tank 100 does not supply heating water, the water temperature in the first water tank 100 is bath water temperature, the heating water temperature is higher than bath water temperature, and the bath water and the heating water are supplied in a staggered manner, so as to satisfy different water temperature demands of people for bath water and heating water. It should be noted that the first preset water temperature is a set value of the water temperature of the first tank 100 when the first tank 100 is not supplied with heating water, and the water heater 300 is continuously operated to continuously supply water to the first tank 100 when the first tank 100 is supplied with heating water, and therefore, both the water supply mode of the first tank 100 and the heating mode of the first tank 100 are for the condition that the first tank 100 is not supplied with heating water. In this embodiment, the heating water temperature is 55 ℃, but in other embodiments, the heating water temperature may be other temperature values such as 60 ℃ or 50 ℃.
Further, the first power (i.e., the heating power of the water heater 300 in the water replenishing mode of the first water tank 100) and the second power (i.e., the heating power of the water heater 300 in the heating mode of the first water tank 100) are both greater than the heating power of the water heater 300 in the heating mode of the first water tank 100, so that when the first water tank 100 is not supplied with heating water, the temperature of water in the first water tank 100 can reach the bath water temperature in a short time, and when a plurality of people take a bath in a concentrated time period, the waiting time can be effectively shortened. In addition, compared to the water for bathing, the demand of most people for heating water often allows a slightly longer process for waiting for the water temperature to rise, and the arrangement of the water heater 300 with slightly lower power when the first water tank 100 supplies heating water has the effect of reducing energy consumption on the basis of meeting the heating demand. Further, the fourth power is greater than the heating power of the water heater 300 when the first water tank 100 supplies heating water, so that the water temperature in the second water tank 200 can quickly reach the second preset water temperature when the second water tank 200 is replenished with water, and the energy consumption can be reduced on the basis of meeting the heating requirement.
Alternatively, as shown in fig. 1, when the indoor ambient temperature reaches the preset indoor temperature, the heating control valve 121 is closed, the first water tank 100 stops supplying heating water, and the power of the water heater 300 is reduced until the water temperature of the first water tank 100 is lowered from the heating water temperature to the bath water temperature, to achieve the effect of reducing energy consumption. When the indoor ambient temperature is lower than the preset indoor temperature, the heating control valve 121 is opened and the first tank 100 starts to supply heating water.
Alternatively, the third power may be equal to or different from the heating power of the water heater 300 when the first tank 100 supplies heating water. In the technical solution of this embodiment, the third power is changed according to a difference between a water temperature in the second water tank 200 and an outdoor environment temperature, specifically, when the water temperature in the second water tank 200 is low, the third power is high, when the water temperature in the second water tank 200 is high, the third power is low, when the outdoor environment temperature is low, the third power is high, when the outdoor environment temperature is high, the third power is low, specifically, a plurality of optimal third power values corresponding to the water temperature in the second water tank 200 and the outdoor environment temperature can be tested in a laboratory, data under a plurality of working conditions are input to the controller, and when the water heater system operates, the controller adjusts the third power according to a real-time working condition. The heating power of the water heater 300 when the first water tank 100 supplies heating water is changed according to the difference between the water temperature in the first water tank 100 and the outdoor environment temperature, specifically, when the water temperature in the first water tank 100 is low, the heating power of the water heater 300 is high, when the water temperature in the first water tank 100 is high, the heating power of the water heater 300 is low, when the outdoor environment temperature is low, the heating power of the water heater 300 is high, when the outdoor environment temperature is high, the heating power of the water heater 300 is low, specifically, the optimal heating power values of the water heater 300 corresponding to the water temperatures in the first water tank 100 and the outdoor environment temperature can be tested in a laboratory, data under various working conditions is input into the controller, and when the water heater system operates, the controller adjusts the heating power of the water heater 300 according to the real-time working conditions. In the present embodiment, the water heater 300 is an air-source water heater, but in other embodiments, the water heater may also be other types of water heaters such as a ground source heat pump water heater.
Alternatively, the water heater system provided in the present embodiment is further provided with a bathing period, for example, eight to ten nights of a day, in which the heating control valve 121 is always closed regardless of whether the first water tank 100 is supplied with the bathing water, to ensure the supply of the bathing water from the first water tank 100 during that period.
The control method for the water heater system provided by the embodiment respectively sets the preset water temperatures for the first water tank 100 and the second water tank 200, and distinguishes the water temperatures when the first water tank 100 is used for supplying heating water and when the first water tank is not used for supplying heating water, so that the use requirements of people for different hot water temperatures are met, and the effect of reducing energy consumption on the basis of meeting the use requirements is realized.
