In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention 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 invention and are not intended to limit the invention.
According to the wall-mounted furnace and solar energy linkage control method provided by the embodiment of the invention, after the wall-mounted furnace is powered on and started, the temperature of a solar water tank is firstly obtained; judging whether the temperature of the solar water tank exceeds a preset temperature threshold of the solar water tank or not; when the judgment result is yes, starting a solar energy working mode so that the solar energy circulating water passes through the plate type heat exchanger heat exchange wall-mounted boiler heating circulating water; when the judgment result is negative, the working mode of the wall-mounted boiler is started, and the solar circulating pump is kept to stop running, so that the user is not limited by weather when heating in rainy days; and when the weather is fine, the gas cost of the wall-mounted furnace can be saved, and the effects of energy conservation and emission reduction are achieved.
It can be understood that the embodiment of the invention is applied to the linkage control of the wall-hanging stove and the solar energy, and the method described below can be stored in the form of software in the wall-hanging stove or the solar energy host, and preferably, in the wall-hanging stove host. In the following, the software of the technical scheme is stored in the wall-hanging stove as an example and is explained with reference to the specific embodiment.
Example one
Fig. 1 shows a flow chart for implementing a wall-hanging stove and solar energy linkage control method provided by an embodiment of the invention, and the method includes the following steps:
in step S101, the temperature of the solar water tank is acquired after the wall-hanging stove is powered on.
In the embodiment of the invention, after the wall-mounted furnace is electrified and started, the circulating pump of the wall-mounted furnace starts to operate.
In the embodiment of the invention, the temperature of the solar water tank is detected by the temperature sensor according to actual conditions and can be any temperature value between 0 ℃ and 120 ℃.
In step S102, determining whether the temperature of the solar water tank exceeds a preset temperature threshold of the solar water tank; when the judgment result is yes, executing step S103; when the judgment result is no, step S104 is executed.
In the embodiment of the present invention, the preset temperature threshold of the solar water tank is used to determine whether to start a value of the solar operating mode, and the value may be set according to user requirements, such as 50 ℃, 51 ℃, 55 ℃, 60 ℃, and the like, and is not limited specifically.
In step S103, a solar energy operation mode is started to allow the solar circulating water to pass through the plate heat exchanger heat exchange wall-mounted boiler heating circulating water.
In an embodiment of the invention, after the solar energy working mode is started, the solar energy circulating pump is synchronously controlled to operate, and at the moment, the solar energy circulating pump and the wall-mounted boiler operate simultaneously, so that the heat dissipation of the terminal heating heat dissipation equipment is accelerated, and the room temperature can be rapidly increased.
According to the embodiment of the invention, the solar circulating water passes through the plate heat exchanger to exchange heating circulating water in the circulating water channel of the wall-mounted boiler, so that the purpose of heating is achieved.
In step S104, the wall-hanging furnace operation mode is started and the solar circulation pump is kept stopped.
When the wall-mounted boiler is started in the working mode, the heating circulating water of the wall-mounted boiler is not required to be heated through the heat exchange of the solar circulating water, so that the solar circulating pump is kept to stop operating, and the energy efficiency can be saved. It can be understood that in the case of the wall-hanging furnace operating mode, the solar circulating pump is always kept in the stopped state; however, in the solar energy operation mode, the circulation pump of the wall-hanging stove needs to be kept in a continuous operation state or an intermittent operation state, which is specifically referred to in the second to sixth embodiments.
According to the wall-mounted furnace and solar energy linkage control method provided by the embodiment of the invention, after the wall-mounted furnace is powered on and started, the temperature of a solar water tank is firstly obtained; judging whether the temperature of the solar water tank exceeds a preset temperature threshold of the solar water tank or not; when the judgment result is yes, starting a solar energy working mode so that the solar energy circulating water passes through the plate type heat exchanger heat exchange wall-mounted boiler heating circulating water; when the judgment result is negative, the working mode of the wall-mounted boiler is started, and the solar circulating pump is kept to stop running, so that the user is not limited by weather when heating in rainy days; and when the weather is fine, the gas cost of the wall-mounted furnace can be saved, and the effects of energy conservation and emission reduction are achieved.
Example two
Referring to fig. 2, on the basis of the first embodiment, after the step S103, the method further includes:
in step S201, determining whether the temperature of the solar water tank is lower than a first preset temperature difference threshold in real time; when the judgment result is yes, executing step S202; when the judgment result is no, step S203 is executed.
In an embodiment of the present invention, the first preset temperature difference threshold is a difference between a preset temperature threshold of the solar water tank and a solar return difference temperature. For example, if the preset temperature threshold of the solar water tank is 65 ℃ and the solar return difference temperature is 10 ℃, the first preset temperature difference threshold may be determined to be 55 ℃ between 65 ℃ and 10 ℃.
In the embodiment of the invention, the solar energy heating can be effectively prevented from being frequently started near the temperature threshold value preset by the solar water tank by setting the solar energy return difference temperature.
In step S202, the solar operation mode is exited, the wall-hanging stove operation mode is entered, and the solar circulation pump is controlled to stop operating.
In step S203, the solar operation mode is maintained.
For example, in the solar energy operating mode, the first preset temperature difference threshold is 35 ℃, when the temperature of the solar water tank is detected to be less than 35 ℃ in real time, the solar energy operating mode is exited, the wall-hanging furnace operating mode is entered, and the solar circulating pump is controlled to stop operating.
According to the wall-mounted boiler and solar energy linkage control method provided by the embodiment of the invention, in the solar energy working mode, when the temperature of the solar water tank is monitored to be lower than the first preset temperature difference threshold value in real time, the solar energy working mode is exited to enter the wall-mounted boiler working mode, and the solar energy circulating pump is controlled to stop running, so that the heating required temperature of a user can be ensured in time, and the flexible conversion between the wall-mounted boiler mode and the solar energy mode is realized.
EXAMPLE III

in step S301, in the process of heating the outlet water temperature, it is determined in real time whether the outlet water temperature exceeds a preset temperature threshold for heating; when the judgment result is yes, executing step S302; when the determination result is no, step S303 is executed.
In the embodiment of the invention, the heating outlet water temperature refers to the outlet water temperature of the wall-hanging stove heating circulating water subjected to heat exchange through the plate heat exchanger. It can be understood that, in order to ensure that the temperature of the free room reaches the user's requirement, the temperature of the heat dissipation device is controlled by setting a preset heating temperature threshold (i.e. the maximum heating temperature) to prevent the temperature from being too high.
In one embodiment of the invention, the heating outlet water temperature can be obtained by real-time detection of a temperature sensor; the preset heating temperature threshold may be determined according to a room temperature required by a user, and if the user requires a room temperature of 30 ℃, the preset heating temperature threshold may be set to 40 ℃, 50 ℃, or the like.
In step S302, the solar circulation pump and the wall-hanging stove circulation pump are controlled to be operated intermittently.
As an embodiment of the present invention, the start time of the intermittent operation may be set according to the heat preservation effect of the room, and if the room heat preservation effect is good and the temperature reduction is slow, the time for the solar circulating pump and the circulating pump of the wall-hanging stove to operate may be reduced, and the time for the solar circulating pump and the circulating pump of the wall-hanging stove to stop may be increased, for example, set to operate for 3 minutes, stop for 10 minutes, and so on.
In another embodiment of the present invention, if the room has a poor heat preservation effect and the temperature is rapidly reduced, the operation time of the solar circulating pump and the circulating pump of the wall-hanging stove can be increased, and the stop time of the solar circulating pump and the circulating pump of the wall-hanging stove can be reduced, for example, the operation is set to 6 minutes, the stop time is set to 4 minutes, and the like, and the operation is repeated in this way.
In step S303, the solar circulation pump and the wall-hanging stove circulation pump are controlled to be continuously operated.
According to the wall-mounted boiler and solar energy linkage control method provided by the embodiment of the invention, in the process of heating the temperature of the heating outlet water, when the temperature of the heating outlet water is judged to exceed the preset heating temperature threshold in real time, the solar circulating pump and the circulating pump of the wall-mounted boiler are controlled to operate intermittently; when the heating water outlet temperature is judged to be lower than the preset temperature threshold value of heating in real time, the circulating pump of the solar energy and the circulating pump of the wall-mounted boiler are controlled to continuously operate, so that the heating temperature required by a user can be guaranteed, and energy can be effectively saved.
Example four
Referring to fig. 4, on the basis of the third embodiment, after the step S302, the method further includes:
in step S401, it is determined in real time whether the heating water temperature is lower than a second preset temperature difference threshold; if yes, executing step S303; when the judgment result is no, step S302 is performed.
In the embodiment of the present invention, the second preset temperature difference threshold is a difference between a preset heating temperature threshold and a return difference temperature of heating. For example, if the preset heating temperature threshold is 60 ℃ and the return air temperature is 12 ℃, the second preset temperature difference threshold may be determined to be 48 ℃ to 60 ℃ -12 ℃.
As an embodiment of the present invention, for example, when the heating outlet water temperature is lower than the second preset temperature difference threshold value of 35 ℃, the solar circulating pump and the circulating pump of the wall-hanging stove are controlled to be continuously operated, and when the heating outlet water temperature is higher than the second preset temperature difference threshold value of 35 ℃, the solar circulating pump and the circulating pump of the wall-hanging stove are controlled to be in an intermittent operation state. The start-stop time of the intermittent operation is not described in detail herein.
According to the wall-mounted boiler and solar energy linkage control method provided by the embodiment of the invention, in the process of heating the temperature of the heating outlet water, when the temperature of the heating outlet water is judged to be lower than a second preset temperature difference threshold value in real time, the solar energy circulating pump and the circulating pump of the wall-mounted boiler are controlled to continuously operate; when the heating water outlet temperature is judged to be not lower than the second preset temperature difference threshold value in real time, the solar circulating pump and the circulating pump of the wall-mounted furnace are controlled to operate intermittently, so that the heating temperature required by a user can be guaranteed in time, and meanwhile, the energy consumption can be reduced when the heating temperature of the user is reached.
EXAMPLE five
In the first embodiment, after the step S104, the method further includes:
in step S501, it is determined in real time whether the temperature of the solar water tank exceeds a preset temperature threshold of the solar water tank; when the judgment result is yes, step S502 is executed; if the determination result is no, step S503 is executed to maintain the wall-hanging stove operation mode.
In step S502, the wall-hanging stove is controlled to stop operating and the solar operating mode is started.
In the embodiment of the invention, the stop of the wall-mounted boiler refers to stopping combustion, but the circulating pump of the wall-mounted boiler keeps working to supply heat to the heat dissipation equipment through the heating circulating water.
In step S503, the wall-hanging furnace operation mode is maintained.
In the embodiment of the invention, the temperature of the solar water tank is monitored in real time in the working mode of the wall-mounted boiler, and when the temperature of the solar water tank exceeds the preset temperature threshold of the solar water tank, the wall-mounted boiler is controlled to stop working and the solar working mode is started, so that the consumption of fuel gas of the wall-mounted boiler can be reduced, and the effects of energy conservation and emission reduction are achieved.
EXAMPLE six
In the first embodiment, after the step S104, the method further includes:
in the process of burning and heating the wall-mounted boiler, judging whether the heating outlet water temperature of the wall-mounted boiler exceeds a preset heating stop temperature threshold value in real time;
in the embodiment of the present invention, the preset heating stop temperature threshold is generally higher than the preset heating temperature threshold, such as 60 ℃, 63 ℃, 70 ℃, 75 ℃ and the like, and the preset heating stop temperature threshold is not specifically limited, and can be set according to the user requirements.
And when the judgment result is yes, controlling the wall-mounted furnace to stop burning and heating and entering a standby state.
In one embodiment of the invention, the wall-hanging stove stops burning but the circulation pump of the wall-hanging stove continues to operate.
And when the judgment result is negative, keeping the wall-hanging furnace to burn and heat.
According to the wall-mounted boiler and solar energy linkage control method provided by the embodiment of the invention, whether the heating outlet water temperature of the wall-mounted boiler exceeds the preset heating stop temperature threshold value or not is judged in real time in the combustion heating process of the wall-mounted boiler, and when the heating outlet water temperature exceeds the preset heating stop temperature threshold value, the wall-mounted boiler is controlled to stop combustion heating and enter a standby state, so that the phenomenon that the heating outlet water temperature is too high and exceeds the required heating temperature can be prevented, and meanwhile, the energy consumption of the wall-mounted boiler can be effectively reduced.
