Generally speaking, the capacity of the water storage tank 210 of the solar water heater 200 is not large, and most of them are designed with reference to domestic water consumption such as bathing of users. The amount of water does not meet the user's other domestic water needs.

In this embodiment, by setting the incubator 500, the hot water produced by the solar water heater 200 can be guided into the incubator 500 for heat preservation and storage, and the volume of hot water prepared by the solar water heater 200 can be increased to meet the heat supply requirements of the heater 100 at the same time. And users' daily life water.

Specifically, the hot water in the water storage tank 210 first flows into the incubator 500 through the first conduit 310. Since the height of the water storage tank 210 is higher than that of the incubator 500 in most cases, the hot water in the water storage tank 210 can be Direct flow to the incubator 500 under the action of gravity. Alternatively, a circulating pump is provided on the first conduit 310 to ensure that the hot water in the water storage tank 210 can flow into the insulated tank 500 .

The hot water in the insulation box 500 exchanges heat with the heat storage box 110 through the second conduit 320 . Specifically, the water after heat exchange in the second conduit 320 can be directly drained away, or the other end of the second conduit 320 is connected to the water return port 212, the second conduit 320 is provided with a first circulation pump 800, and the inside of the conduit 300 is connected to the heat storage tank. 110 The water after heat exchange is returned to the water storage tank 210 of the solar water heater 200 through the first circulating pump 800 .

The time device is used to obtain and record the time value tx when the heat storage mode is running, and send it to the control device.

Specifically, on the basis of the heating system described above, this embodiment also provides a heat storage control method for the heating system, including the following steps:

Step S200, when the heat storage mode is running, obtain the temperature Tx of the heat storage tank, the temperature Tr of the water storage and the height of the water storage liquid level, and determine the height ratio Hr of the water storage liquid level, and the storage water temperature Tr is the temperature of the water storage tank or the heat preservation The tank temperature controls the opening and closing of the second valve 410 and the first circulation pump 800 based on the heat storage tank temperature Tx, the stored water temperature Tr and the stored water level height ratio Hr.

Preferably, after entering the thermal storage mode, the time value tx is acquired in real time, and when the acquired time value tx falls within the preset high-power time interval, the thermal storage mode is exited.

Preferably, when receiving the heater 100 startup instruction in the heat storage mode, the heat storage mode is also exited. It should be noted that receiving the start-up command of the heater 100 refers to receiving the start-up command sent by the user through the remote control or the control button, and the heater 100 turns on the fan after receiving the start-up command. Under the action, heat is supplied to the outside, and the heat storage tank stops heat storage.

Specifically, the preset low power time interval refers to a valley time period of electricity consumption preset in the memory of the heater 100 . For example, in a certain area, the electricity consumption valley time period is between 0:00 am and 6:00 am, and the electricity charge for the 6 hours between 0:00 am and 6:00 am is lower, and after 6:00 am to the early morning of the next day The 18-hour electricity bill between midnight is relatively high, so the 6-hour time period between midnight and 6 am can be entered into the heater 100, and the heater 100 obtains the information of the time period and determines it as the preset low power time interval. In addition, the preset high power time interval refers to the preset power consumption peak time period in the memory of the heater 100, for example, the 18-hour time period between 6:00 a.m. and 0:00 a.m. of the next day is entered into the heating determined in the device 100 as the preset high power time interval.

Preferably, the heater 100 can be provided with a time setting program, which can be entered by the user through a mobile phone or a remote control; optionally, the heater 100 can obtain location information through the Internet of Things, and then obtain location information through the Internet of Things. The valley time period and peak time period of power consumption in the area, and the obtained valley time period of power consumption is determined as the preset low power time period, and the obtained peak time period of power consumption is determined as the preset high power time period range, and can be updated automatically.

In the heat storage heater control method described in this embodiment, after the heater 100 is turned off or the user selects the heat storage mode to be turned on, the heater 100 automatically enters the heat storage control program, and judges whether it is in a low-cost electricity consumption by time. During the electricity valley time period, the heat storage is carried out at the time when the electricity cost is low, so that when the electricity cost is high during the day, the heat stored in the heat storage tube is used for heating first, and then the heater is turned on for heating, which can reduce the user's Reduce electricity consumption, reduce electricity costs, reduce electricity consumption during peak hours of electricity consumption, and improve the uniformity of regional electricity consumption.

When it is determined that the time value tx falls into the preset low power time interval, it is now in the valley value interval of power consumption, the electricity cost is low, the power consumption in the area is small, and the voltage is stable. Acquire heat storage tank temperature Tx, water storage temperature Tr and water storage liquid level height again, determine water storage liquid level height ratio Hr, described storage water temperature Tr is water storage tank temperature or incubator temperature, based on described heat storage tank temperature Tx, the storage water temperature Tr and the storage water level height ratio Hr control the opening and closing of the second valve 410 and the first circulating pump 800 .

Specifically, taking the hot water supply from the thermal storage tank 500 to the thermal storage tank 110 as an example, this embodiment controls the connection between the second valve 410 and the first The opening and closing of the circulating pump 800 is to inject hot water into the incubator 500 when the hot water in the water storage tank 210 meets the heat demand, and regulate the flow of the water storage tank 210 to the incubator according to the temperature and the liquid level ratio in the incubator 500. The opening time and closing time of injecting hot water in 500, to ensure that the hot water with maximum heat is stored in the incubator 500, so as to be better heated with the heat storage box 110.

It should be noted that the water storage temperature Tr is the temperature Tc of the water storage tank or the temperature Tb of the incubator. When the water storage tank 210 is used to directly supply heat to the heat storage tank 110, the insulated tank 500 may not be provided. At this time, the temperature Tc of the water storage tank is used to judge and control the opening and closing of the second valve 410 and the first circulation pump 800; When the thermal storage tank 500 is set between the thermal storage tank 110, the hot water in the water storage tank 210 will first flow to the thermal storage tank 500 for storage, and then provide hot water to the thermal storage tank 110 through the thermal storage tank 500. The temperature Tb is used to control the opening and closing of the second valve 410 and the first circulation pump 800 .

Similarly, the water storage liquid level height ratio Hr is the water storage tank liquid level height ratio Hc or the heat preservation tank liquid level height ratio Hb, and the second valve is controlled by the water storage tank liquid level height ratio Hc or the heat preservation tank liquid level height ratio Hb 410 and the opening and closing of the first circulating pump 800.

In the heat storage control method of the heating system described in this embodiment, after the heat storage mode of the heater is turned on, the heater automatically enters the heat storage control program, and judges whether it is in the low electricity consumption valley time period by time , heat storage is carried out when the electricity cost is low, so that when the electricity cost is high during the day, the heat stored in the heat storage tube is used for heating first, and then the temperature of the heat storage tank, the storage water temperature and the height ratio of the water storage liquid are compared Hr To control the second valve 410 and the first circulation pump 800, so that when the solar water heater meets the heating capacity, the hot water stored in the solar water heater can be used to store heat, which can not only reduce the user's electricity consumption, reduce electricity costs, but also It can reduce the power consumption during the peak period of power consumption and improve the uniformity of regional power consumption.

Specifically, controlling the opening and closing of the second valve 410 and the first circulating pump 800 based on the temperature Tx of the thermal storage tank, the temperature Tr of the stored water, and the height ratio Hr of the liquid level of the stored water described in this embodiment includes:

When the temperature Tx of the heat storage tank is less than the second preset temperature value T2, and the stored water temperature Tr is greater than or equal to the first preset temperature value T1, the second valve 410 and the first circulating pump are opened 800.

Specifically, the second preset temperature value T2 refers to the lower temperature value of the heat storage tank that needs to be heated during the preset low-power time interval, and needs to be turned on when the temperature value of the heat storage tank is lower than the second preset temperature value T2 The heater stores heat. For example, the user selects the heat storage level through the remote control or the operation button, and different heat storage levels correspond to different second preset temperature values T2. Preferably, the second preset temperature value T2 is between 40°C and 65°C, preferably 55°C.

The first preset temperature value T1 refers to the temperature of the water in the water storage tank 210 or the heat preservation tank 500 is relatively high, suitable for heat exchange with the heat storage tank 110 , within the range of 45°C to 55°C, preferably 50°C.

During the preset low-power time interval, when the temperature of the heat storage tank 110 is less than 40°C and the storage water temperature Tr is greater than or equal to 50°C, the second valve 410 and the first circulating pump 800 are turned on to control the water storage tank 210 or The thermal insulation tank 500 supplies hot water to the thermal storage tank 110 side.

Further, after opening the second valve 410 and the first circulation pump 800, when the temperature Tx of the heat storage tank is greater than or equal to the third preset temperature value T3 and the temperature of the stored water Tr is less than the fourth When the preset temperature value T4 and the height ratio Hr of the stored water level are less than any one of the first preset height ratios H1, the second valve 410 and the first circulation pump 800 are closed.

Specifically, the third preset temperature value T3 is the highest temperature value that can be reached in the heat storage tank 110, or if the temperature in the heat storage tank 110 is higher than the third preset temperature value T3, more energy consumption will be consumed , such as the maximum temperature in the heat storage tank 110 reaches 75°C.

Specifically, the fourth preset temperature value T4 is the temperature at which the water storage tank 210 or the heat preservation tank 500 is no longer suitable for providing heat to the heat storage tank 110 , which is in the range of 35°C to 45°C, preferably 40°C. When the water temperature in the water storage tank 210 or the insulated tank 500 is lower than 40° C., it is no longer suitable for supplying heat to the heat storage tank 110 . At this time, the second valve 410 and the first circulation pump 800 are closed.

Specifically, the first preset height ratio H1 refers to the ratio of the water volume to the overall height of the tank when the water stored in the incubator 500 or the water storage tank 210 is about to or has been drained, and is in the range of 0% to 10%, preferably 5 %.

Specifically, after the heat storage tank 500 or the water storage tank 210 provides hot water to the side of the heat storage tank 110, when the temperature of the heat storage tank 110 has reached 75°C, the temperature of the water storage tank 210 or the heat storage tank 500 has been lower than 40°C, and the storage When the water volume in the water tank 210 or the incubator 500 is less than 5%, the second valve 410 and the first circulation pump 800 are closed.

Further, after the second valve 410 and the first circulating pump 800 are closed, it is determined that the temperature Tx of the thermal storage tank is lower than the third preset temperature value T3, and then the electric heater is controlled to be turned on.

After the water storage tank 210 or the heat preservation tank 500 stops supplying hot water to the side of the heat storage tank 100, if the temperature Tx of the heat storage tank is still lower than 75°C, it indicates that the temperature Tx of the heat storage tank has not reached the full storage temperature, because the water storage tank 210 or If the temperature of the incubator 500 is lower than 40°C, and/or the water volume in the water storage tank 210 or the incubator 500 is less than 5%, causing the heat storage in the heat storage tank 110 to stop, the electric heater is controlled to be turned on for further heat storage through the electric heater.

Further, when the time value tx does not fall into the preset low-power time interval, and the start instruction of the heater 100 is obtained, it is determined that the temperature Tx of the heat storage tank is less than the fifth preset temperature value T5 and the When the stored water temperature Tr is greater than or equal to the first preset temperature value T1, the second valve 410 and the first circulation pump 800 are turned on.

Specifically, the time value tx does not fall into the preset low-power time interval, which means that the current time value during the operation of the thermal storage mode does not fall into the preset low-power time interval, that is, it falls into the preset high-power time interval at this moment, High electricity consumption time period. The start command of the heater 100 refers to the start command of the heater 100 to turn on the heating mode and supply heat to the surrounding environment. For example, when the air conditioner fan receives the start command, the fan is turned on to blow hot air to the surrounding environment.

Specifically, the fifth preset temperature value T5 refers to a temperature value at which heat of the heat storage tank 110 is exhausted, and is in the range of 25°C to 35°C, preferably 30°C. When the temperature of the heat storage box 110 is lower than 30° C., it is difficult for the heat storage box 110 to provide heat to the external environment.

When the heating function is turned on in the preset high-power time interval, it is determined that the temperature Tx of the thermal storage tank is less than 30°C, and the storage water temperature Tr is greater than 50°C, then the second valve 410 and the first circulation pump 800 are turned on, and the water storage tank 210 or the hot water in the heat preservation box 500 is guided into the heat storage box 110 for heat storage.

Further, after the second valve 410 and the first circulation pump 800 are turned on within the preset high power time interval, when the temperature Tx of the heat storage tank is greater than or equal to the third preset temperature value T3, the When the water storage temperature Tr is less than the fourth preset temperature value T4 and the height ratio of the water storage liquid level Hr is less than the first preset height ratio H1, the second valve 410 and the first circulation pump are closed 800.

Specifically, the fourth preset temperature value T4 is the temperature at which the water storage tank 210 or the heat preservation tank 500 is no longer suitable for providing heat to the heat storage tank 110 , which is in the range of 35°C to 45°C, preferably 40°C. When the water temperature in the water storage tank 210 or the insulated tank 500 is lower than 40° C., it is no longer suitable for supplying heat to the heat storage tank 110 . At this time, the second valve 410 and the first circulating pump 800 are closed.

Further, after the second valve 410 and the first circulating pump 800 are closed, it is determined that the temperature Tx of the thermal storage tank is lower than the fifth preset temperature value T5, and then the electric heater is controlled to be turned on.

Further, in the heat storage mode, record the heating time during which the temperature of the heat storage tank is heated from the second preset temperature value to the third preset temperature value in the heat storage mode within the continuous preset number of days, and calculate the continuous The average heating time within the preset number of days;

For example, record the time for heating the temperature of the heat storage box from 60°C to 75°C in the heat storage mode for 3 consecutive days, such as 60 minutes on the first day, 61 minutes on the second day, and 65 minutes on the third day, and take three consecutive days The average value is 61 minutes, then when the previous judgment result is that the temperature of the heat storage tank is lower than the second preset temperature value T2, the heat storage action will be performed 61 minutes before the last moment of the preset low-power time interval, For example, the electric heater is controlled to be turned on, and/or the second valve 410 and the first circulation pump 800 are turned on. For example, the last moment of the preset low-power time interval is 6:00 am, then the electric heater is controlled to be turned on at 4:59 am, and/or the second valve 410 and the first circulation pump 800 are turned on to ensure that Set the temperature of the heat storage tank to the highest temperature at the last moment of the low power time interval, reduce the waiting time before the user turns on the heating mode, and reduce the loss of heat.
