[0063] 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.

[0064] The heat loss-based heating control method provided in the embodiment of the present application, in the application scenario, takes whole-house heating as one of the embodiments, and includes the following steps S102 to S110. Among them:

[0065] Step S102, determining the exterior wall parameters, window parameters and window orientation of each room.

[0066] Specifically, external wall parameters: These parameters usually include the wall's thickness, material (such as brick, concrete, gypsum board, etc.), the performance of the insulation material, and the area of ​​the wall. The material and thickness of the wall directly affect its thermal conductivity, that is, the wall's ability to block heat flow. The area of ​​the wall determines the total amount of heat exchange. For example, the thicker the wall, the better the insulation performance; and the larger the wall area, the more heat may be lost through the wall.

[0067] Window parameters: Window parameters include window size, glass type (single-layer glass, double-layer glass, Low-E glass, etc.), window frame material (such as aluminum alloy, wood, PVC, etc.) and sealing performance. Windows are one of the main ways for rooms to exchange heat with the outside world. Different types of windows have different conduction and blocking capabilities for heat flow. For example, double-layer Low-E glass windows have better thermal insulation performance and can effectively reduce heat loss.

[0068] Window orientation: The orientation of a window affects the amount of solar radiation it receives, which in turn affects the heat gain of a room. For example, a south-facing window will receive more solar radiation during the northern hemisphere winter, providing additional heat to the room. Conversely, a north-facing window will receive less solar radiation and have lower heat gain.

[0069] By comprehensively considering these parameters, the heat loss and heat gain of each room under different conditions can be calculated more accurately, and then the appropriate heating water temperature can be set for each room to achieve precise heating. This heating control method based on heat loss helps to improve energy efficiency, reduce energy waste, improve indoor comfort, and reduce heating costs.

[0070] Step S104, obtaining the thermal conductivity and window transmittance of each room according to the exterior wall parameters, window parameters and window orientation of each room.

[0071] Specifically, the exterior wall parameters include:

[0072] Exterior wall material: Different materials have different thermal conductivity. For example, concrete generally has a higher thermal conductivity than wood. The thermal conductivity of a wall determines how well it blocks heat flow. Wall thickness: The thicker the wall, the longer the heat conduction path and the slower the heat loss.

[0073] Insulation: Using insulation in walls can significantly reduce thermal conductivity because insulation materials generally have low thermal conductivity.

[0074] Wall area: The area of ​​the wall determines the total amount of heat exchange, but does not affect the thermal conductivity per unit area.

[0075] Window parameters include:

[0076] Glass type: Different types of glass (such as single-layer glass, double-layer glass, Low-E glass) have different effects on the transmittance of thermal radiation and sunlight. For example, Low-E glass can reduce the transmission of thermal radiation, thereby reducing heat loss.

[0077] Window frame material: The material of the window frame will also affect the overall thermal performance of the window. For example, metal window frames generally have higher thermal conductivity than plastic window frames.

[0078] Sealing performance: Good sealing can reduce air leakage and thus reduce heat loss due to air convection.

[0079] Window orientations include:

[0080] Solar radiation: Windows facing different directions receive different amounts of solar radiation. For example, south-facing windows in the northern hemisphere receive more solar radiation in winter than north-facing windows, which affects the heat gain of the room.

[0081] Season and time of day: The position of the sun changes with the season and time of day, affecting window transmittance and heat gain.

[0082] By taking these factors into account, the thermal conductivity and window transmittance of each room can be calculated to determine the appropriate heating strategy.

[0083] Step S106, obtaining the heat loss of each room according to the thermal conductivity, and obtaining the heat gain of each room according to the window transmittance.

[0084] Specifically, thermal conductivity (λ) is an inherent property of a material, which indicates the amount of heat that can be transferred per unit area and per unit temperature gradient per unit time. The unit of thermal conductivity is usually Watt per meter Kelvin (W / (m·K)). Heat loss refers to the amount of heat inside the room that is transferred to the outside through the exterior walls, windows, etc. Heat loss mainly occurs through heat conduction, especially in winter when it is warm indoors and cold outdoors.

[0085] Window transmittance: refers to the ability of a window to transmit solar radiation, that is, how much solar radiation can enter the room through the window. Transmittance is usually expressed as a percentage. Heat gain refers to the heat transferred from the outside to the inside, which is usually undesirable in summer, but can be used as a natural warming method in winter. Heat gain mainly comes from solar radiation, which is transmitted into the room through the window.

[0086] For example, a room with high heat loss may require a higher heating water temperature, while a room with high heat gain may require a lower heating water temperature or less heating time. This heat loss-based heating control method helps improve energy efficiency and indoor comfort.

[0087] Step S108, determining the heating water temperature of each room according to the heat loss heat and the heat gain heat.

[0088] Specifically, determine the heating water temperature: Based on the calculation results of heat loss and heat gain, the required heating water temperature for each room can be determined. The determination of heating water temperature should take into account the efficiency of the heating system, the insulation performance of the room, and the comfort requirements of the users. Usually, the heating water temperature will be set within a range to ensure that sufficient heat is provided even on the coldest days. Consider the type of heating system: Different types of heating systems may require different water supply temperatures. For example, a floor radiant heating system may require a lower water temperature, while a traditional radiator system may require a higher water temperature.

[0089] Step S110, adjusting the heating temperature of the heating water pipe in each room according to the heating water temperature in each room.

[0090] Specifically, the required heating water temperature for each room can be determined based on the calculation results of heat loss and heat gain. The determination of heating water temperature should take into account the efficiency of the heating system, the insulation performance of the room, and the comfort requirements of the users. Usually, the heating water temperature will be set within a range to ensure that sufficient heat can be provided even on the coldest days.

[0091] Consider the type of heating system: Different types of heating systems may require different supply water temperatures. For example, a radiant floor heating system may require a lower water temperature, while a traditional radiator system may require a higher water temperature.

[0092] In the above-mentioned heating control method based on heat loss, the heat loss and heat gain of each room can be accurately calculated according to the specific building parameters of different rooms, such as external wall parameters, window parameters and window orientation, so as to determine the most suitable heating water temperature and realize personalized heating adjustment for each room. It can avoid energy waste in traditional heating systems, ensure that each room can achieve the ideal comfort level, improve heating efficiency and user living experience. By accurately controlling the heating water temperature in each room, unnecessary energy consumption can be reduced and energy conservation and emission reduction can be achieved. This heating control method helps to reduce the operating cost of the heating system. By optimizing heating control, energy waste is reduced, which can save heating costs for users in the long run, and also help to reduce the maintenance and operating costs of the heating system.

[0093] In an exemplary embodiment, determining the exterior wall parameters, window parameters, and window orientation of each room includes:

[0094] In response to the data input operation based on the wall-mounted boiler user terminal, the external wall parameters, window parameters and window orientation are determined; wherein the external wall parameters include the external wall height and the external wall length; and the window parameters include the window area.

[0095] Specifically, the external wall parameters include the height and length of the external wall. These dimensions are used to calculate the surface area of ​​the wall because they directly affect the heat loss of the wall. The surface area of ​​the wall determines the area in contact with the outside world, thus affecting the loss of heat. These data can be obtained through on-site measurements or architectural drawings.

[0096] Window parameters include the window area, as it determines the heat loss and heat gain that can occur through the window. The larger the window area, the greater the possible heat loss, but at the same time more solar heat can enter during the day. Window size data can also be obtained through site measurements or architectural drawings.

[0097] The orientation of a window determines the amount of solar radiation it receives throughout the day, which is particularly important for heat gain in the winter. For example, a south-facing window will receive more solar radiation during the northern hemisphere winter, which can help increase indoor temperatures. Information about window orientation can be determined through site observation or building layout drawings.

[0098] In actual operation, users can input these data through the user interface of the wall-mounted boiler. The wall-mounted boiler system will automatically calculate and adjust the heating water temperature based on these input parameters, combined with information such as outdoor temperature and indoor set temperature, to achieve accurate heating in each room. Usually equipped with an intelligent control module, it can adjust the heating strategy according to real-time data to ensure energy efficiency and comfort.

[0099] In this embodiment, by determining the external wall parameters, window parameters and window orientation, the heat loss and heat gain of each room are accurately calculated, and the most appropriate heating water temperature can be set for each room to ensure that the heating system operates more efficiently and reduces energy waste. Personalized heating adjustment can ensure that the temperature of each room meets the user's comfort requirements and avoid the situation where some rooms are overheated while others are underheated.

[0100] In an exemplary embodiment, obtaining the heat loss of each room according to the thermal conductivity includes:

[0101] Get the indoor and outdoor temperature difference index;

[0102] The heat loss of each room is obtained by multiplying the thermal conductivity, indoor and outdoor temperature difference index, and the height and length of the exterior wall of each room.

[0103] Specifically, thermal conductivity, also known as thermal conductivity, is a measure of the relationship between the amount of heat that passes through a unit area per unit time and the temperature difference between the two sides of the surface. The unit of thermal conductivity is usually Watt per meter Kelvin (W / (m·K)), which depends on the type and state of the material.

[0104] The indoor and outdoor temperature difference index refers to the difference between the indoor temperature and the outdoor temperature. This difference is the driving force that pushes heat to transfer from the high temperature side to the low temperature side through the wall.

[0105] The exterior wall height and length are used to calculate the surface area of ​​the wall because heat losses occur over the entire surface area of ​​the wall.

[0106] Among them, the calculation formula 1 is as follows:

[0107] Q (heat loss) = U × S (wall) × △T;

[0108] Among them, Q (heat loss) is the heat loss, unit (W); U is the thermal conductivity, which varies according to the building materials, unit (W / m²·K); S (wall) is the wall area of ​​the room, unit (m 2 ); △T is the temperature difference between indoor and outdoor, unit (℃).

[0109] In this embodiment, by accurately calculating the heat loss of each room, the heating system can provide the required heat more accurately, avoid overheating or underheating, and thus improve energy efficiency. Accurate heat loss calculation can ensure that the temperature of each room is maintained within the user's comfortable range, and the room will not be too cold due to insufficient heat supply, or too hot due to excessive heat.

[0110] In an exemplary embodiment, the heat gain of each room is obtained according to the window transmittance, including:

[0111] Get outdoor solar radiation intensity;

[0112] The heat gain of each room is obtained by multiplying the window transmittance, outdoor solar radiation intensity and the window area of ​​each room.

[0113] Specifically, obtaining the outdoor solar radiation intensity is the first step in calculating heat gain. It is necessary to know the intensity of outdoor solar radiation at a specific time. This data can be obtained through data provided by a meteorological station or measured using a specific instrument. Window transmittance refers to the window's ability to transmit solar radiation. It is a ratio value that indicates how much solar radiation can pass through the window into the room. This parameter depends on the type of window (such as single-layer glass, double-layer glass, Low-E glass, etc.) and its manufacturing material. The window area of ​​each room is another important parameter to consider when calculating heat gain. The larger the window area, the greater the possible heat gain.

[0114] By multiplying the window transmittance, outdoor solar radiation intensity and the window area of ​​each room, the heat gain of each room can be obtained. The calculation formula 2 is as follows:

[0115] Q (heat gain) = H × S (window) × K;

[0116] Where Q (heat gain) is the heat gain of solar radiation to room temperature, unit (W); H is the outdoor solar radiation intensity, unit (W / m 2 ); S (window) is the window area, unit (m 2 ); K is the window transmittance, which varies depending on the material and is generally between 0.6-0.9.

[0117] In this embodiment, by accurately calculating the solar radiation intensity and window transmittance, solar energy can be effectively utilized, reducing dependence on traditional energy sources, thereby improving overall energy efficiency. Accurate heat gain calculation helps maintain a stable indoor temperature, avoid indoor overheating due to excessive solar radiation, and improve the comfort of living and working environments.

[0118] In an exemplary embodiment, as shown in FIG2 , the heating water temperature of each room is determined according to the heat loss heat and the heat gain heat, including:

[0119] Step S202, obtaining the hot water specific heat capacity and hot water flow rate;

[0120] Step S204, determining the hot water temperature rise of the wall-mounted boiler according to the hot water specific heat value and the hot water flow rate, and the heat difference between the heat loss and the heat gain;

[0121] Step S206, adjusting the heating water temperature of each room accordingly according to the hot water temperature rise.

[0122] Specifically, the specific heat capacity of hot water is a fixed value, usually 4187 joules per kilogram Kelvin (J / (kg·K)), which is a measure of the temperature change when water absorbs or releases heat. In the heating system, this parameter is the basic data used to calculate the storage and release of heat during the transportation of water. Hot water flow refers to the volume of water passing through the heating system per unit time, usually expressed in cubic meters per hour (m³ / h) or kilograms per hour (kg / h). This parameter can be obtained through actual measurement or design calculation, and is crucial to determining the heating water temperature.

[0123] By calculating the heat loss and heat gain of each room, the heat difference that needs to be compensated in the room can be obtained. Heat loss is usually determined by the insulation performance of the building, while heat gain is related to factors such as solar radiation and heat dissipation of indoor equipment. Then, based on the difference between heat loss and heat gain, as well as the specific heat capacity and flow rate of hot water, the hot water temperature rise that the wall-mounted boiler needs to provide can be calculated. This temperature rise refers to the temperature increase required for water in the heating system after it comes out of the boiler before it reaches the radiator in each room. According to the calculated hot water temperature rise, the outlet water temperature is adjusted through the control system of the wall-mounted boiler to ensure that the heating water temperature in each room can meet the thermal comfort requirements while optimizing energy efficiency.

[0124] In this embodiment, accurate calculation and adjustment are used to ensure that the heating system provides heat on demand and avoid energy waste. It is ensured that each room can reach a suitable temperature to improve the comfort of the occupants. Combined with the intelligent control system, automatic adjustment is achieved to improve the response speed and adjustment accuracy of the system. Optimizing the heating water temperature can reduce fuel consumption and reduce heating costs.

[0125] In an exemplary embodiment, the external wall parameters further include the thermal conductivity of the wall building materials, and the window parameters further include the thermal conductivity of the window building materials; according to the external wall parameters, window parameters and window orientation of each room, the thermal conductivity and window transmittance of each room are obtained, including:

[0126] The thermal conductivity of the wall building materials in each room is used as the thermal conductivity of each room;

[0127] Determine the window daylighting rate based on the window orientation;

[0128] The window transmittance of each room is determined based on the thermal conductivity of the window building materials and the window daylighting rate of each room.

[0129] Specifically, the thermal conductivity of wall building materials is a measure of the ability of wall materials to transfer heat through a unit area per unit time, usually expressed in watts per meter Kelvin (W / (m·K)). The lower the thermal conductivity, the better the thermal insulation performance of the material.

[0130] The thermal conductivity of window materials is similar to that of walls, and the thermal conductivity of window materials also affects their thermal insulation performance. The window frame material (such as aluminum alloy, wood or PVC) and the type of glass (such as single-layer, double-layer or Low-E glass) will affect its thermal conductivity.

[0131] Window daylighting rate: refers to the proportion of natural light that a window can receive in the vertical direction, which is related to the orientation, position and surrounding environment of the window. The daylighting rate determines how much solar radiation heat a window can receive during the day. The window daylighting rate can be determined by the ratio of the window area to the area of ​​the room's exterior wall. For example, if the total area of ​​a room's exterior wall is 20 square meters and the window area is 4 square meters, then the window daylighting rate is 20%. The orientation of the window has a great influence on the daylighting rate. Different orientations receive different amounts of solar radiation at different times, thus affecting the daylighting rate. South-facing windows usually have a higher daylighting rate because they receive more direct sunlight during the day.

[0132] The window transmittance can be determined based on the thermal conductivity of the window building material and the window daylighting rate. Daylighting rate affects the amount of solar radiation received, while the thermal conductivity of the building material affects the window's ability to block heat energy.

[0133] In this embodiment, by using the thermal conductivity of the wall building material as the thermal conductivity, the heat blocking effect of the wall in winter can be estimated, thereby evaluating the heating demand. By determining the window daylighting rate and the thermal conductivity of the window building material, the window transmittance can be calculated, and then the contribution of the window to the indoor heat gain in winter and the impact on the indoor heat load in summer can be evaluated.

[0134] The most detailed embodiment of this application is:

[0135] As shown in Figure 3, it is a schematic diagram of the heating system. The room types include living room, balcony, kitchen, bathroom and bedroom. The heating system includes a wall-mounted boiler, a wall-mounted boiler user end, a heating water pipe and a heating control device based on heat loss;

[0136] The wall-mounted boiler is connected to the wall-mounted boiler user terminal (not shown in the figure); the wall-mounted boiler user terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection equipment, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc.

[0137] The heating water pipe is connected to the wall-mounted boiler through a manifold and laid on the floor of each room to provide heating for each room;

[0138] The heating control device is connected with the heating water pipe and is used for adjusting the heating temperature of the heating water pipe in each room.

[0139] For example, a household uses a mobile phone APP to input parameters for the wall-mounted boiler during installation. The wall in the living room that contacts the outdoors is 9.3m long, and the room is 3.2m high. The wall is covered with ceramic tiles, and the thermal conductivity of the ceramic tile wall is 1.4W / (m²·K).

[0140] One day the outdoor temperature is -20℃, and the user's home needs a comfortable room temperature of around 22℃.

[0141] Substituting the above parameters into formula 1, we get: Q (heat loss) = 1.4 × (9.3 × 3.2) × (22-(-20)) = 1750W; that is, the heat loss of the wall is 1.75kW per second.

[0142] Use the mobile phone APP to input parameters for the wall-mounted boiler. The window length is 2m and the height is 1.5m. The APP obtains today's solar radiation intensity of 300 (W / m 2 ), the window transmittance is 0.7.

[0143] Substituting the above parameters into Formula 2, we obtain: Q (thermal gain) = 300 × (3 × 1.5) × 0.7 = 630W.

[0144] In summary, the room as a whole generates heat loss, the value is 1750-630=1120 W. That is, the room will increase its heat loss Q (x) by 1120 W per second.

[0145] Under normal circumstances, the room is heated according to the 70°C guideline, and at a heating flow rate of 0.15L / S, according to the formula Q(x)=C×△T×F;

[0147] So △T=1120W÷(4.2×10 3 J / (kg·℃)×0.15L / S)=1.8℃;

[0148] During this period, the space needs to be heated according to the guidelines of 70℃+1.8℃ and 71.8℃.
