Description

Technical Field

[0001] This invention relates to the field of heating, and more particularly to a method and system for dynamically adjusting the heating mode based on the user's remaining heating supply. Background Technology

[0002] Currently, most prepaid household heat meters are integrated units, meaning the flow sensor, temperature sensor, and IC card sensor are all integrated into one meter body and installed inside the pipe shaft. This design presents problems such as inconvenience for users to pay and susceptibility of electronic components to moisture damage. While some technologies have adopted a separate design or simply connected the thermostat to the valve to address these issues, the following technical drawbacks still exist:

[0003] 1. Inflexible control strategies: Existing prepaid logic is mostly based on "shutting off the valve when payment is overdue" or simple "low balance alarm," lacking refined utilization of users' remaining heat value. When a user's heating balance is insufficient, the heating is often directly cut off, which causes a sudden drop in indoor temperature, resulting in a very poor user experience.

[0004] 2. Lack of thermal inertia consideration: Heating systems usually have a large thermal inertia. Most existing temperature control panels are simple on / off control or on / off ratio control, which cannot make advance predictions based on the thermal characteristics of the pipes and the thermal inertia of the room, resulting in large temperature fluctuations and easy waste of heat energy.

[0005] 3. Insufficient linkage: The user's indoor temperature control needs are disconnected from the prepaid balance status. When the user's heating balance is about to run out, there is no automatic guidance for the "energy-saving mode," causing the heat to be depleted without their knowledge and the heating to suddenly stop.

[0006] Therefore, in summary, there is a need for an intelligent prepaid heating method and system that can dynamically adjust the control strategy based on the user's heating balance status and combine thermal inertia prediction to achieve a smooth transition. Summary of the Invention

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0073] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0074] This embodiment discloses a method for dynamically adjusting the heating mode based on the user's remaining heating supply. The purpose is to enable the system to dynamically adjust the heating mode in the user's room based on the user's remaining heating supply. When the balance is sufficient, the user can adjust the heating mode at will. When the balance is insufficient or close to the warning line, the system will automatically adjust the heating mode dynamically and combine it with thermal inertia to extend the heating duration, so as to achieve a smooth transition from heating to heating stoppage.

[0075] Specifically, refer to Figure 1 The method includes the following steps:

[0076] S1, based on the current remaining heat balance Q of the user's heating supply. remain Compared with the predicted heat consumption per unit time P predict Calculate the current heating duration t pred ;

[0077] Obtain the current remaining heat balance Q of the user's heating supply from the system. remain Compared with the predicted heat consumption per unit time P predict ;

[0078] Among them, the current remaining heat balance Q remain To directly obtain and predict the heat consumption P per unit time predict To indirectly obtain and predict the heat consumption P per unit time predict The calculation process is as follows:

[0079] When T set -T room_current At temperatures above 2℃, the temperature is in the rising phase, and P... predict The calculation formula is:

[0080] P predict =K×(T set -T room_current )×F history +P base ;

[0081] Where K is the thermal coefficient, T set To preset the heating temperature, T room_current F represents the current room temperature of the user's house. history P is the historical average flow factor. base For heat loss of the pipeline foundation;

[0082] The K-value is a physical constant reflecting the thermal insulation performance and thermal inertia of a building. It represents the proportion of power required to raise or lower the room temperature by 1°C. A higher K-value indicates poorer insulation, requiring more power to reach the preset heating temperature T. set This requires more heat to be consumed. A smaller K value indicates better house insulation, which is necessary to reach the preset heating temperature T.set If the heat is less, then less energy is consumed.

[0083] When |T set -T room_current When |≤2℃, this is the isothermal maintenance stage, P predict The calculation formula is:

[0084] ;

[0085] in, This refers to "the actual heat consumption power within the i-th sampling period," where i represents the sampling time series (e.g., data points from 1 hour ago, 2 hours ago, ... up to N hours ago), i is a positive integer, and i∈(1,N). The actual average heat consumption per unit time over the past 24 hours can be calculated using this data, and this actual average heat consumption is used as the predicted heat consumption P per unit time. predict At this point, it no longer depends on the preset heating temperature T. set Compared with the current room temperature T of the user's house room_current The temperature difference between them is close to 0, so the predicted heat consumption P per unit time is obtained by referring to historical experience. predict .

[0086] When T room_current -T set When the temperature is above 2℃, this is the cooling phase, P predict The calculation formula is:

[0087] .

[0088] Current heating duration t pred The calculation formula is:

[0089] t pred =Q remain / P predict ;

[0090] Among them, Q remain P represents the current remaining heat balance. predict To predict the heat consumption per unit time.

[0091] Because of P predict When used as the denominator, it cannot be 0. Logically speaking, if T... room_current -T set At >2℃, P predict It should be 0, but the system's calculation result will be problematic because... It tends towards 0, but is always greater than zero; therefore, it is used here. Represents 0.

[0092] S2, Preset maximum heating duration Thigh and minimum heating duration T low and preset heating temperature T set ;

[0093] The maximum heating duration T can be set manually. high and minimum heating duration T low and preset heating temperature T set Furthermore, during use, users can adjust the maximum heating duration T at any time. high and minimum heating duration T low and preset heating temperature T set To establish a humanistic setting.

[0094] Among them, steps S1 and S2 are not in any particular order; they are parallel preparatory steps before implementing different heating methods.

[0095] S3. Calculate and determine t pred With T low t pred With T high The size relationship is considered, and different heating methods are developed for different size relationships;

[0096] Based on the current heating duration t calculated in step S1 pred and the maximum heating duration T preset in step S2 high and minimum heating duration T low .

[0097] Calculate t respectively pred With T low t pred With T high The difference or relative to t pred With T low T high The size is compared, and different heating methods are output according to different comparison results. Specifically, it includes the following three types.

[0098] Mode 1: Comfort Follow Mode;

[0099] If t pred >T high Then it will work according to the user-defined status;

[0100] It can employ PID closed-loop control, fully responding to the preset heating temperature T set by the user on the indoor temperature control panel. set At this time, the valves on the pipeline respond quickly and operate at full power to reach the preset heating temperature T as quickly as possible. set Energy consumption and limitations are not taken into account.

[0101] Mode 2: Inertial energy-saving mode;

[0102] If T low ≤t pred ≤T high Then, for the preset heating temperature T set After making corrections, the corrected heating temperature T is obtained. set The corrected formula is as follows:

[0103] T set =T set -α×(1-t) pred / T high );

[0104] Where α is the dynamic decay coefficient of the temperature setpoint;

[0105] If the user forcibly increases the preset heating temperature T at this time... set This will lead to the predicted heat consumption P per unit time. predict The increase leads to a decrease in the current heating duration t pred If the heating duration is reduced, the system will immediately adjust the heating duration based on the new current heating duration t. pred Further reduce the actual operating temperature T set This negative feedback mechanism forces users to extend the heating duration (t) when their balance is insufficient. pred The only option is to actively lower the preset heating temperature T. set This achieves the goal of energy conservation. Simultaneously, combined with inertia compensation, the system will ensure energy efficiency as the room temperature approaches the preset heating temperature T. set Beforehand, reduce the valve opening to utilize the residual heat of the pipeline to maintain the temperature and reduce frequent valve operation.

[0106] Under "balance warning status", the system allows deviations from the user's original preset heating temperature T. set The maximum allowable temperature drop (i.e., the maximum permissible temperature drop). Its physical meaning is: the current heating duration t for energy conservation and extending the residual calorific value. pred The system is only willing to lower the user's set temperature to the preset temperature.

[0107] The magnitude of the dynamic attenuation coefficient α of the temperature setpoint is mainly related to the outdoor ambient temperature T. out It is related to the building's thermal characteristics / location of the building, which can also be replaced with the building's thermal characteristics / historical temperature drop rate.

[0108] Outdoor ambient temperature T out Used as a safety antifreeze mechanism, the pipeline freezing warning temperature can be preset. Outdoor ambient temperature T out Data can be collected directly from outdoor temperature sensors or obtained through remote meteorological data.

[0109] When the outdoor temperature is extremely cold (e.g., -20°C), if the indoor preset heating temperature T is forcibly maintained... set A significant reduction in temperature could lead to frozen indoor pipes or excessively low wall temperatures, posing safety hazards. Therefore, the lower the outdoor temperature, the smaller the value of α should be (limiting the temperature drop); the milder the outdoor temperature, the larger the value of α can be (allowing for a greater temperature drop to save energy).

[0110] The building's thermal characteristics and its location can be considered as a single parameter, referred to as the environmental conditioning coefficient, and used as... express;

[0111] If a user's house has extremely poor insulation (rapid heat loss), even slightly reducing the valve opening will cause the room temperature to drop rapidly. In this case, a large α value is not required to achieve significant energy savings.

[0112] The faster the historical temperature drop rate (the worse the insulation), the smaller the value of α; the better the insulation performance (the greater the thermal inertia), the larger the value of α can be.

[0113] The dynamic attenuation coefficient α of the temperature setpoint is not a fixed value, but a safety and energy-saving parameter that is adaptively adjusted based on the ambient temperature.

[0114] Specifically, the formula for calculating the dynamic attenuation coefficient α of the temperature setpoint is as follows:

[0115] ;

[0116] in, The preset maximum value of the dynamic attenuation coefficient α for the temperature setpoint, where e is the natural constant. This is the environmental regulation coefficient. This refers to the current outdoor ambient temperature. The preset pipe freezing warning temperature (default is -10℃).

[0117] When T out ≤T freeze When a zone is identified as a high-risk area for frost prevention, α is forcibly set to 0, meaning the preset heating temperature T is not lowered. set This ensures that the user's room temperature remains unchanged and prevents the pipes from freezing and cracking.

[0118] When T out >T freeze When α∈(0, α max The value of α can be in the interval (0, α). max The α value can increase linearly or non-linearly. The higher the outdoor temperature, the larger the α value, allowing for a greater allowable energy-saving temperature drop, thus improving energy efficiency. Among these, α... max The maximum allowable temperature drop threshold preset on the system (the default setting is 3.0℃, which can be modified by the user).

[0119] Environmental regulation coefficient The α value is used to control the response rate of the α value to changes in outdoor temperature. The β value is determined by a large amount of experimental data during the system development phase. It is used to balance the linear relationship between energy saving effect and user comfort, and to prevent drastic changes in the set temperature due to small fluctuations in the outside temperature. It is an empirical constant determined based on debugging experience.

[0120] in, ∈ (0,1);

[0121] When the user's house is located in a cold region or is an old house ∈ (0.05, 0.15); at this point, the algorithm applies the current outdoor temperature T. out It is not sensitive to slight increases in temperature and maintains a high set temperature to prevent a sudden drop in room temperature due to fluctuations in ambient temperature.

[0122] When the user's house is located in a temperate zone or is an energy-efficient building. ∈ (0.25, 0.35). At this point, the algorithm applies the current outdoor temperature T. out The system responds quickly to changes and can fully utilize solar thermal gain, minimizing valve opening while ensuring basic heating needs are met, thus achieving significant energy savings.

[0123] When the current outdoor temperature is close to the freezing point T freeze hour, As the outdoor temperature approaches 0, the calculated α also approaches 0 (the system determines not to cool down, prioritizing heating safety). out As the temperature rises, the value of α gradually increases, but it will not exceed α. max .

[0124] parameter Figure 2 The experimental data and parameters obtained are based on the following preset parameters:

[0125] Among them, when the preset pipeline freezing warning temperature is -10℃, t pred =36 hours, T high =72 hours, (1-t) pred / T high )=0.5, user-set temperature is T set =22℃.

[0126] Mode 3: Low-consumption heat preservation mode;

[0127] If t pred <T low The system will preset the heating temperature T set Adjust to the preset basic insulation temperature T min ,

[0128] Or the system no longer follows the preset heating temperature T. set Instead of adjusting, it directly jumps to the basic insulation temperature T. min ; and until the current remaining heat balance Q of the user's heating supply. remain Set the value to 0, then close the control pipe valve.

[0129] At the same time, limit the maximum valve opening K. max K max The calculation formula is K max =P safe / P predict (where P) safe To maintain T min Required safe power). If P predict The valve opening is very large (in very cold weather), and is strictly limited to a very small range, solely for antifreeze and to maintain the minimum survival temperature, until the balance is depleted and the valve is closed.

[0130] When switching to Mode 2 or Mode 3, the temperature control panel can display messages such as "Insufficient heating capacity, please pay promptly," effectively informing users of the insufficient balance and facilitating subsequent payment. Simultaneously, a human-computer interaction interface can be configured to allow users to promptly access various parameters.
