[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The heating water heating method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the control device 102 communicates with the heating equipment 104, the water temperature collection device 106, and the heating device 108 through the network. Specifically, the control device 102 generally refers to a device for controlling the actuator and collecting sensor data, which can receive input signals from sensors or operators, and output control signals after processing to control the action of the actuator to achieve control of the production process or power system. The heating equipment 104 is a heating facility set up to keep the space where people live or produce in a suitable thermal state. The heating equipment can generally include a wall-mounted boiler, a heater, etc. In this embodiment, the heating equipment 104 refers to a wall-mounted boiler. The water temperature collection device 106 refers to a device that can collect the temperature of the heating water, such as a temperature sensor, a thermometer, etc. The heating device 108 refers to a device that can generate heat and transfer the heat to the heated object or space. Specifically, during the process of heating heating water, the control device 102 responds to a heating request initiated by a user and turns on the heating device 104 for delivering heating water; obtains the outlet water temperature of the heating water output by the heating device 104 collected by the water temperature collection device 106, and the inflow temperature of the heating water when it flows into the heating device 108 through the first pipe; the heating device 108 is connected to the heat exchange device through a second pipe, and the length of the second pipe is less than or equal to the set length; when the inflow temperature and the outlet water temperature meet the heating conditions, the heating device 108 is controlled to heat the heating water so that the heated heating water flows into the heat exchange device.

[0052] In one embodiment, Figure 2 As shown, a method for heating water for heating is provided, and the method is applied to Figure 1 Taking the control device 102 in the example as an example, the method includes the following steps:

[0053] Step S202, in response to a heating request initiated by a user, start a heating device for delivering heating water.

[0054] Among them, a heating request refers to a formal or informal request made by a user or resident to a heating service provider to request the activation or adjustment of heating services to meet the temperature requirements of their living or working environment. Generally speaking, in the cold winter, residents or users usually need heating to keep the room warm, or a sudden temperature drop or continuous cold weather may prompt residents to make a heating request.

[0055] Heating water refers to water used in heating systems. It has many types and sources. Specifically, heating water can be hot water for urban central heating: it is mainly based on municipal central heating, and is supplied to users for heating after water treatment, heating, and transportation. The heat source is usually provided by the boiler room, and it is transported in hot water pipes after pretreatment. It has the advantages of wide heating range, stable heat source, and stable quality, but the cost is relatively high. Heating water can also be geothermal water: it uses high-temperature groundwater deep underground for heating. Its temperature is higher than other heating methods. It is very popular in some cold areas. It has the advantages of no pollution, no noise, and strong stability. However, due to geological conditions, the scope of development and utilization of geothermal water is relatively limited. Heating water can also be heat pump water: heat pump technology is used to heat and pressurize low-temperature natural water sources and groundwater for heating. The heating process can be adjusted according to actual conditions, which can better meet the needs of different users. It has the advantages of environmental protection, energy saving, and safe use. It is widely used in some newly built communities and villas and other low-rise residential buildings.

[0056] Heating equipment is a heating facility set up to keep the space where people live or produce in a suitable thermal state. Heating equipment generally includes a wall-mounted boiler, a heater, etc. In this embodiment, the heating equipment 104 refers to a wall-mounted boiler.

[0057] Specifically, in the cold winter, residents or users usually need heating to keep the room warm, or a sudden drop in temperature or continued cold weather may prompt users to make heating requests. In this case, the control device needs to respond to the heating request initiated by the user and turn on the heating equipment for delivering heating water so that the heating water flows into the heat exchange equipment to meet the temperature requirements of the user's living or working environment.

[0058] Step S204, obtaining the outlet water temperature of the heating water output by the heating equipment collected by the water temperature collecting device, and the inflow temperature of the heating water when it flows into the temperature increasing equipment through the first pipe.

[0059] Among them, the water temperature acquisition device refers to a device that can collect the temperature of the heating water. Specifically, the water temperature acquisition device mainly works based on the temperature sensor. When the water temperature changes, the resistance, capacitance and other parameters of the temperature sensor will change accordingly, thereby generating a corresponding electrical signal. The water temperature acquisition device is responsible for receiving these electrical signals, and after internal processing, the water temperature data is output in digital form for users to analyze and apply. The water temperature acquisition device can be, for example, a temperature collector: a device specifically used to measure and record temperature data, including water temperature, record the temperature signal and process and analyze it through a computer or mobile application. Its measurement principle generally adopts thermal resistors, thermocouples, infrared and other methods. The water temperature acquisition device can also be, for example, a temperature data acquisition instrument: a device specifically used to receive, process and output temperature data, with data storage and processing functions, capable of real-time monitoring and recording of water temperature data, usually equipped with a display screen and alarm function, convenient for users to view and monitor the water temperature. The water temperature collection device can also be an ultrasonic water depth and water temperature meter, for example: it combines the functions of ultrasonic ranging and water temperature measurement, can accurately measure the depth and temperature of the water area, is suitable for complex hydrological environments, and has the advantages of high precision, fast response and non-contact measurement.

[0060] The outlet water temperature refers to the temperature of the heating water when the heating equipment just outputs the heating water. The inflow temperature refers to the temperature of the heating water when it just flows into the heating equipment. The heating equipment and the heat exchange equipment are connected by a second pipe, and the length of the second pipe is less than or equal to the set length. Among them, the first pipe and the second pipe are both pipes for transporting heating water. The set length can be a set, extremely short length while ensuring that the heating water can be transported normally, which can ensure that the heat loss of the heating water is extremely small when it flows from the heating equipment into the heat exchange equipment.

[0061] Specifically, after the heating device for delivering heating water is turned on, the control device can obtain the outlet water temperature of the heating water output by the heating device collected by the water temperature collection device, and the inflow temperature of the heating water when it flows into the heating device through the first pipe, so as to determine the delivery status of the heating water. Exemplarily, the operation of obtaining the outlet water temperature of the heating water output by the heating device collected by the water temperature collection device, and the inflow temperature of the heating water when it flows into the heating device through the first pipe can be actively obtained or passively received.

[0062] Step S206, when the inlet temperature and the outlet water temperature meet the heating conditions, control the heating device to heat the heating water so that the heated heating water flows into the heat exchange device.

[0063] The heating condition refers to the condition under which the heating water needs to be heated. In this embodiment, the heating condition may include, for example, a temperature difference value preset based on actual experience. If the difference between the inflow temperature and the outflow temperature is greater than or equal to the temperature difference value, it indicates that the inflow temperature and the outflow temperature meet the heating condition.

[0064] Heat exchange equipment, commonly known as heat exchangers or heat exchangers, is a device that performs various heat exchanges. Their main function is to transfer heat from one medium to another, or to convert heat from one form to another. The working principle of heat exchange equipment is based on three basic ways of heat transfer: heat conduction, convection and heat radiation. In a heat exchanger, two fluids of different temperatures exchange heat through a solid wall (such as a metal plate, tube, etc.). The hot fluid transfers heat to the wall, and then the wall transfers heat to the cold fluid, thereby achieving heat transfer. In this embodiment, the heat exchange equipment mainly refers to a heat sink. There are many types and structures of heat exchange equipment to adapt to different use conditions and requirements. The types of heat exchangers include: Plate heat exchanger: composed of high-efficiency heat transfer corrugated plates and frames. The plates are clamped between a fixed clamping plate and a movable clamping plate by bolts to form many flow channels. Rubber seals are used between the plates to ensure that the two fluid media will not leak. The herringbone corrugation can increase the disturbance of the fluid and improve the heat transfer effect. Spiral plate heat exchanger: a high-efficiency heat exchanger equipment, suitable for heat exchange between steam-steam, steam-liquid, and liquid-liquid. The structural form can be divided into two types: non-detachable and detachable. Shell and tube heat exchanger: also known as shell and tube condenser, divided into carbon steel, stainless steel and mixed materials according to the material; divided into fixed tube plate type, floating head type, U-tube type, etc. according to the form; divided into single tube pass, double tube pass and multi-tube pass according to the structure. Shell and tube heat exchanger: a general process equipment for heat exchange operation, widely used in chemical, petroleum, petrochemical, electric power and other industrial sectors. Heat pipe heat exchanger: using the efficient heat transfer characteristics of heat pipes, it has the characteristics of large heat transfer, small temperature difference, light weight and small size. Full heat exchanger: built-in supply and exhaust fans, through the heat exchange core to achieve two-way equal replacement of indoor exhaust dirty air and outdoor fresh air, while recovering energy.

[0065] Specifically, if the difference between the inflow temperature and the outlet water temperature is greater than or equal to the temperature difference, it indicates that the heat loss of the heating water during the transportation process is relatively large, and the inflow temperature and the outlet water temperature meet the heating conditions. Therefore, the heating water needs to be heated, that is, the heating device needs to be controlled to heat the heating water so that the heated heating water flows into the heat exchange device. In a specific embodiment, the heating device includes an energy storage unit and a heating unit, and the control device can control the energy storage unit to supply power to the heating unit so that the heating unit heats the heating water flowing into the heating device. In another specific embodiment, the control device can also adjust the heating power of the heating device according to the difference between the inflow temperature and the outlet water temperature, and control the heating device to heat the heating water according to the heating power.

[0066] The above heating water heating method responds to the heating request initiated by the user, turns on the heating device, and the heating device starts to deliver heating water to the heat exchange device, obtains the outlet water temperature of the heating water output by the heating device collected by the water temperature collection device, and the inflow temperature of the heating water when it flows into the heating device through the first pipe, wherein the heating device and the heat exchange device are connected by a second pipe, and the length of the second pipe is less than or equal to the set length, that is, the length of the second pipe between the heating device and the heat exchange device is small, which can ensure that the heat loss of the heating water from the heating device to the heat exchange device is small and can be ignored. When the inflow temperature and the outlet water temperature meet the heating conditions, the heating device is controlled to heat the heating water so that the heated heating water flows into the heat exchange device. By adopting the above heating water heating method, when the heat of the heating water has been lost, the heating water can be heated by the heating device closer to the heat exchange device, thereby ensuring the accuracy of the heating of the heating water.

[0067] In one embodiment, the temperature increasing device includes an energy storage unit and a heating unit. In this embodiment, controlling the temperature increasing device to heat the heating water includes:

[0068] The energy storage unit is controlled to supply power to the heating unit so that the heating unit heats the heating water flowing into the temperature increasing device.

[0069] Among them, the energy storage unit refers to a device that can store electrical energy or other forms of energy and release it when needed to supply it to the power system or other equipment. In this embodiment, the type of energy storage unit is a capacitor energy storage unit. The heating unit refers to a device that can generate heat during operation, and this heat may be converted from electrical energy, chemical energy, mechanical energy, etc.

[0070] Specifically, when the inlet temperature and the outlet water temperature meet the heating conditions, since the heating device includes an energy storage unit and a heating unit, the control device controls the heating device to heat the heating water in the following process: the control device controls the energy storage unit to first power the heating unit, and after the heating unit is charged, it heats the heating water flowing into the heating device.

[0071] In this embodiment, the heating device includes an energy storage unit and a heating unit. The control device controls the energy storage unit to supply power to the heating unit so that the heating unit heats the heating water flowing into the heating device, thereby ensuring the stable operation of the heating water heating process.

[0072] In one embodiment, Figure 3 As shown, the heating water heating method also includes:

[0073] Step S302, controlling the water temperature collecting device to collect the water temperature of the heating water flowing out of the heating device to obtain the heating temperature.

[0074] Among them, after controlling the heating device to heat the heating water, the control device can control the water temperature collection device to collect the water temperature of the heating water flowing out of the heating device, obtain the heating temperature, and then determine the heating condition of the heating water by the heating device.

[0075] Step S304: When the temperature difference between the heating temperature and the water outlet temperature does not satisfy the temperature difference condition, the heating power of the heating unit is adjusted.

[0076] Among them, the temperature difference condition refers to a preset temperature difference condition. In this embodiment, the temperature difference corresponding to the temperature difference condition is extremely small, that is, if the temperature difference between the heating temperature and the water outlet temperature does not meet the temperature difference condition, it indicates that the temperature difference between the heating temperature and the water outlet temperature is large.

[0077] Specifically, when the temperature difference between the heating temperature and the outlet water temperature does not meet the temperature difference condition, the temperature difference between the heating temperature and the outlet water temperature is large, so the control device needs to adjust the heating power of the heating unit. It can be understood that the temperature difference between the heating temperature and the outlet water temperature represents the absolute value of the temperature difference between the heating temperature and the outlet water temperature. For example, the temperature difference between the heating temperature and the outlet water temperature is a positive value, and the temperature difference between the heating temperature and the outlet water temperature does not meet the temperature difference condition, indicating that the heating temperature is too high, so the heating power of the heating unit needs to be reduced. Similarly, the temperature difference between the heating temperature and the outlet water temperature is a negative value, and the temperature difference between the heating temperature and the outlet water temperature does not meet the temperature difference condition, indicating that the heating temperature is too low, so the heating power of the heating unit needs to be increased.

[0078] Step S306, returning to the step of controlling the water temperature collection device to collect the water temperature of the heating water flowing out of the heating device to obtain the heating temperature, until the temperature difference between the heating temperature and the outlet water temperature meets the temperature difference condition.

[0079] Specifically, after adjusting the heating power of the heating unit, it is necessary to re-control the water temperature collection device to collect the water temperature of the heating water flowing out of the heating device, obtain a new heating temperature, and re-judge the temperature difference between the heating temperature and the outlet water temperature until the temperature difference between the heating temperature and the outlet water temperature meets the temperature difference condition.

[0080] In this embodiment, the heating power of the heating unit is adjusted according to the change in the temperature difference between the heating temperature and the water outlet temperature. The heating power of the heating unit can be flexibly adjusted according to the heating conditions of the heating water, thereby improving the flexibility of heating the heating water.

[0081] In one embodiment, the energy storage unit includes a plurality of energy storage capacitors. Figure 4 As shown, the heating water heating method also includes:

[0082] Step S402, obtaining the energy storage threshold and the energy storage capacity of each energy storage capacitor.

[0083] Among them, the energy storage capacitor is a device that can hold electric charge, also known as a capacitor. The energy storage threshold refers to the maximum value of stored energy. The energy storage capacity refers to the actual energy storage battery capacity of each energy storage capacitor at the current moment.

[0084] Specifically, the control device may obtain the energy storage threshold and the energy storage capacity of each energy storage capacitor, thereby determining the current energy storage status of each energy storage capacitor.

[0085] Step S404: determine a target energy storage capacitor whose energy storage capacity is less than the energy storage threshold from among the energy storage capacitors, and charge the target energy storage capacitor.

[0086] The target energy storage capacitor refers to the energy storage capacitor that needs to be charged, and can also be understood as the energy storage capacitor with insufficient energy storage.

[0087] Specifically, before controlling the heating unit to heat the heating water flowing into the heating device, it is necessary to first charge the energy storage unit that provides heating for the heating unit. That is, a target energy storage capacitor whose energy storage capacity is less than the energy storage threshold can be determined from each energy storage capacitor, and the target energy storage capacitor can be charged.

[0088] In this embodiment, a target energy storage capacitor whose energy storage capacity is less than the energy storage threshold is determined from each energy storage capacitor, and the target energy storage capacitor is charged, which can ensure that the energy storage of the energy storage capacitor is maximized, thereby ensuring the stable operation of the heating water heating process.

[0089] In one embodiment, Figure 5 As shown, charging the target energy storage capacitor includes:

[0090] Step S502: determining a target charging power corresponding to a target energy storage capacitor based on a preset correlation between energy storage capacity and charging power.

[0091] Among them, the preset correlation between the energy storage capacity and the charging power refers to the correlation between the preset energy storage capacity and the charging power of the charging power source. It can be understood that the smaller the energy storage capacity, the greater the charging power.

[0092] Specifically, the target charging power corresponding to the target energy storage capacitor can be determined based on the preset correlation between the energy storage capacity and the charging power, so as to charge the target energy storage capacitor according to the target charging power later.

[0093] Step S504: charging the target energy storage capacitor based on the target charging power.

[0094] Specifically, charging the target energy storage capacitor based on the target charging power can ensure the energy storage capacity of the energy storage capacitor, thereby ensuring the stable operation of the heating water.

[0095] In one embodiment, Figure 6 As shown, a heating system is also provided, which includes: a heating device 104, a water temperature collection device 106, a heating device 108, a heat exchange device 110, and a control device 102; the heating device 104, the water temperature collection device 106, and the heating device 108 are all connected to the control device 102;

[0096] Heating equipment 104, used for delivering heating water;

[0097] The water temperature collecting device 106 is used to collect the outlet temperature of the heating water output by the heating device 104 and the inflow temperature of the heating water when it flows into the heating device 108 through the first pipe; the heating device 108 is connected to the heat exchange device 110 through a second pipe, and the length of the second pipe is less than or equal to the set length;

[0098] The heating device 108 is used to heat the heating water so that the heated heating water flows into the heat exchange device 110;

[0099] The control device 102 is used to implement any one of the methods in the above embodiments.

[0100] Specifically, the above-mentioned heating system is equipped with a heating device for conveying heating water, which can ensure the stable transportation of the heating water; is equipped with a water temperature collecting device for collecting the outlet temperature of the heating water output by the heating device and the inflow temperature of the heating water when it flows into the heating device through the first pipe, which can strictly monitor the water temperature of the heating water conveyance process; is equipped with a heating device for heating the heating water, which can make the heated heating water flow into the heat exchange device; is equipped with a control device to implement the above-mentioned method, and when the heat of the heating water has been lost, the heating water can be heated by the heating device close to the heat exchange device, thereby ensuring the accuracy of the heating of the heating water.

[0101] In one embodiment, Figure 7 As shown, the temperature increasing device 108 includes an energy storage unit 1081 and a heating unit 1082 ; the energy storage unit 1081 is used to supply power to the heating unit 1082 so that the heating unit 1082 heats the heating water flowing into the temperature increasing device 108 .

[0102] Specifically, the heating system may further include an energy storage unit 1081 and a heating unit 1082. The energy storage unit 1081 is used to supply power to the heating unit 1082 so that the heating unit 1082 heats the heating water flowing into the temperature increasing device 108, thereby ensuring normal heating of the heating water.

[0103] In a specific embodiment, a method for heating water for heating in an actual application scenario is also provided, including:

[0104] At present, when a commonly used gas wall-mounted boiler is set to a certain heating temperature, due to the long transmission path, heat will be lost during the transmission process. Therefore, when it reaches the end of the heating, the actual temperature is often lower than the preset temperature. In order to solve this problem, if the set temperature of the wall-mounted boiler is increased to ensure that the temperature at the end reaches the preset value, this will cause the temperature at the near end to be too high, affecting the user experience. The solution of this application can solve this problem well, and the specific implementation method is as follows:

[0105] The wall-mounted boiler (heating equipment) in this application is a conventional wall-mounted boiler with corresponding basic heating functions, and is also equipped with a WIFI communication module for communication.

[0106] In actual application scenarios, such as Figure 8 As shown, the heating device 104 is connected to the temperature increasing device 108 , the temperature increasing device 108 is connected to the heat exchange device 110 , and the distance between the heating device 104 and the temperature increasing device 108 is much greater than the distance between the temperature increasing device 108 and the heat exchange device 110 .

[0107] Furthermore, a heating device is provided, such as Fig. 9As shown, the heating device includes a heating device housing 3, and is equipped with a water outlet pipe 2 and a water inlet pipe 4. Usually, this heating device is connected in series at one end of the heating water outlet pipe of the wall-mounted boiler. Equipped with an outlet water temperature sensor 1, the outlet water temperature can be collected. Equipped with a capacitor energy storage device 7 (energy storage unit 1081), it can quickly connect multiple energy storage capacitors in parallel, and each energy storage capacitor can be charged separately, so as to realize the rapid charging of the energy storage capacitor. The capacitor energy storage device 7 outputs through a common output end, and can quickly output electric energy with the same voltage and high current. At the same time, it is equipped with an energy charging electronic switch 10, which can quickly charge each energy storage capacitor in multiple ways, and can switch and control the charging and discharging of each charging branch through an electrical signal. Equipped with an internal pipeline 9, a heating tube 8 (heating unit 1082) is arranged in the internal pipeline for heating and connecting the device inlet and outlet pipes. Equipped with a heating tube electronic switch 6, the connection between the capacitor energy storage device 7 and the heating tube 8 can be controlled by controlling the main board 5. When connected, the electric energy released in the capacitor energy storage device 7 is converted into heat energy. Equipped with a positive power supply electrode 11 and a negative power supply electrode 12, used to connect an external power supply to make the device work, such as Fig.10 As shown, the heating device is equipped with a display 13 and an indicator light 14 for displaying the current working status.

[0108] The specific logic is as follows: when the wall-mounted boiler is turned on, the heating device works at the same time. The control device controls the charging electronic switch to turn on, controls the heating unit electronic switch to turn off, and resets. At this time, the energy storage unit is quickly charged. When the user needs to use the heating function of the wall-mounted boiler, the wall-mounted boiler outputs heating hot water to the heating outlet pipe according to the temperature T1 set by the user, and flows into the heating device connected in series to the heating outlet pipe. After the heating hot water reaches the heating device, the heating device detects the temperature of the heating hot water that has arrived, obtains the temperature T2, and returns T2 to the control device through the WIFI module. The control device compares the temperatures of T1 and T2. T3 is the temperature difference set inside the wall-mounted boiler, usually 0.5°C (empirical value, adjustable). When T1-T2≤T3, the heat loss on the heating outlet pipe is not obvious, and the heating device does not work further. When T1-T2>T3, the hot water on the heating outlet pipe loses heat energy significantly. At this time, the heating device controls the charging electronic switch to turn off, and controls the heating unit electronic switch to turn on. The energy storage device releases electrical energy to the heating unit and converts the electrical energy into heat energy. Time Ts is the system preset time, which is 1S (experience value, which can be adjusted). (The capacitor can instantly generate a large current to drive the heating unit relative to ordinary 220V AC) After Ts, the heating unit consumes the energy of the energy storage device, controls the charging electronic switch to turn on, and at the same time, controls the heating unit electronic switch to turn off, quickly charges the energy storage device, and the water temperature collection device re-detects the heating outlet water temperature until the temperature reaches T1-T2≤T3, and the heating device stops working.

[0109] The above method can solve the problem that the actual temperature of the hot water from the wall-mounted boiler is often lower than the preset temperature when it reaches the heating end.
