Description

Technical Field

[0001] The present invention belongs to the technical field of heat distribution and metering, and in particular relates to a heat energy balance distribution and metering method and system. Background Art

[0002] The heat metering schemes commonly used on the market at present mainly include: household meter method and apportionment method (including time-area method and temperature-area method) and other heat metering schemes.

[0003] Household metering cannot truly reflect the user's heating effect, and does not take into account the heat transfer problem between households. Residents on the top floor, bottom floor, corners, and islands consume more heat and have low room temperatures, while households in the middle consume less heat and have high room temperatures, resulting in serious heat conduction, which causes uneven energy distribution and inaccurate metering. Users who save energy autonomously by manually switching valves will disrupt the heat supply balance, bring difficulties to the heat company's regulation, make it difficult to achieve balance, and have large temperature fluctuations. It only solves the metering problem, but the heat company cannot carry out regulation, and cannot achieve energy conservation and consumption reduction or heat on demand.

[0004] The commonly used apportionment methods include the on-off time area method, the temperature area method, and the flow temperature method.

[0005] The on-off time-area method uses the length of time the valve is open as the charging standard. Although it encourages people to save energy, there are still many problems. The room temperature of residents on the top floor, bottom floor, corners, and isolated islands is low, the valve is open for a long time, and the fees are high. The room temperature of residents in the middle is high, the valve is open for a short time, and the fees are low, resulting in uneven energy distribution and inaccurate metering. In addition, if users keep adjusting the temperature, it is easy to disrupt the current balance, and it is not easy to form a balanced state, resulting in large temperature fluctuations.

[0006] The temperature-area method measures heat by building and apportions heat according to the temperature and area of ​​each household's typical room. It solves the problem of inaccurate measurement caused by high heat consumption at both ends of the building and on the top floor, as well as heat transfer between households. It wastes heat sources and has high losses, and cannot be regulated, which is not conducive to energy conservation by heating companies.

[0007] The flow-temperature method uses the ratio of heating user flow to the total flow at the heat settlement point and the temperature difference as the basis for heat distribution. The heat measured by the total heat meter at the heat settlement point in the heating area is distributed to each user. This method is simple and intuitive to measure, easily accepted by residents, and suitable for various forms of heating. However, it still cannot solve the problem of inaccurate measurement caused by high heat consumption at both ends of the building, on the top floor, and heat transfer between households. In addition, the three-way valve used for adjustment is a manual device, which cannot autonomously adjust the heat supply or the indoor temperature. Summary of the invention

[0042] Compared with the prior art, the advantages and positive effects of the present invention are:

[0043] 1. The present invention provides a method for balancing, distributing and metering heating energy, which performs balancing control according to a set room temperature target value, and performs final heat metering after reaching a balanced state, so that the metering data obtained is more accurate. The advantage of the present invention is that the energy distribution of the heating company is more balanced, and balancing control is performed according to actual heat usage, and heat metering is performed according to actual heat usage, so that the control is more precise and the metering is more accurate, while the energy utilization rate is improved and the heat loss is reduced; the heating company can realize heat metering and charging, and can also realize balancing control and room temperature monitoring, so that the control is combined with the actual room temperature, reducing the difficulty of control, and it is equivalent to a plurality of schemes such as balancing control, metering distribution, and room temperature monitoring in one, which reduces the cost while reducing the installation space, and is more suitable for the heat metering transformation of old communities.

[0044] 2. The characteristics of the present invention are: reasonable allocation and actual metering. The total heat supply is allocated in combination with the actual "heat obtained" of each household, so that the more heat is used, the more metering is, and the more fees are paid; balanced regulation and heating on demand. If the indoor temperature needs to be higher, the valve opening is increased to increase the water supply flow rate. If the indoor temperature needs to be lower, the valve opening is reduced to reduce the water supply flow rate. The amount of heat required is determined by the amount of heat supplied, so that heating on demand and metering by heat are truly realized; data empowerment and heating control, providing a full set of data such as flow rate, supply and return water temperature, time, valve opening, room temperature, etc., and using the acquired data for better analysis and better heat management.

[0045] 3. A heat supply energy balance distribution metering method of the present invention compares the theoretical room temperature value with the actual room temperature value to obtain the temperature coefficient. The temperature coefficient can reflect the heat loss and heat gain of the room. If the heat loss is greater than the heat gain, then the theoretical room temperature value should be greater than the actual room temperature value, such as some corner households. If the heat loss is less than the heat gain, then the theoretical room temperature value should be less than the actual room temperature value, such as the middle households. The calorific value actually measured and paid by the end user is affected by the flow temperature number and the temperature coefficient. The flow temperature number is affected by the supply and return water temperature difference and the water supply flow rate. The greater the supply flow rate, the greater the flow temperature number, and the greater the actual paid calorific value; the temperature coefficient is affected by the actual room temperature, that is, the loss and gain of heat. The corner households with a greater heat loss than the heat gain have a low temperature coefficient and a low actual paid calorific value. The middle households with a less heat loss than the heat gain have a high temperature coefficient and a high actual paid calorific value. This truly realizes the actual measurement and on-demand charging of how much heat is used. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0053] Embodiment 1, as Figure 1 to Figure 4 As shown, this application provides a heating energy balance distribution metering method, the purpose of which is to solve the problem of uneven energy distribution caused by inaccurate metering of heating companies, increase energy utilization, reduce losses, and take advantage of the various problems of the household meter method and the apportionment method. Combined with the current heating status, a more complete heating metering method is introduced, which can balance and regulate while measuring heat, solve the problems of difficult regulation and temperature fluctuations, and combine balanced regulation with heat metering and distribution to reduce installation space, making it more suitable for the renovation of old communities. For residents, it solves the problems of uneven heating and inaccurate metering, such as some users paying high fees for substandard room temperatures and needing to open windows for excessively high room temperatures.

[0054] A large building meter is installed in each unit to measure the heat consumption of the entire building. This heat consumption is the total heat value of the unit building. , ultrasonic or electromagnetic heat meters can be selected, and large meters in buildings can also use large-diameter heat meters on the market.

[0055] A flow and temperature collection and control device is installed in each household. The device has an intelligent control valve and a remote communication device. The intelligent control valve can adopt the EVE2000 intelligent flow control integrated valve. The remote communication device adopts NB / 4G / 5G for communication. The intelligent control valve is equipped with a temperature sensor probe for temperature collection, which can directly measure the temperature value of the pipeline. The flow meter is a flow sensor attached to the intelligent control valve, which adopts the principle of ultrasound for measurement. It is combined with the heating energy balance distribution metering and control method provided by the present invention, and integrates the functions of temperature collection, flow metering, prepayment, on-off control, opening control, thermal balance, etc. It can collect data such as supply and return water temperature (Tg / Th) and water supply flow (G), and can also control the flow value entering the household through the valve.

[0056] Each unit also needs to be equipped with a heat distribution device to collect various data, calculate and allocate user heat, and perform final heat metering and allocation. It also needs to support various two-network balance control strategies, perform balance control, and use wireless communication to exchange data with the control center, while performing system and user management and control. The heat distribution device can use a 5G-based intelligent data acquisition device with application number CN202222349799.8, which is produced by Shandong Del Intelligent Digital Co., Ltd.

[0057] An indoor temperature control panel is installed in each household. The temperature control panel is equipped with a temperature sensor to collect indoor temperature values. It communicates with the flow temperature acquisition controller through wired MBUS or wireless lora and controls its valve opening. It communicates with the heat distributor through wired MBUS or wireless lora to obtain the valve control strategy and specific opening. The temperature control panel monitors the actual room temperature and controls the valve opening of the flow temperature acquisition controller. The heat distribution device combines the balance control strategy to determine the specific valve opening and sends it to the temperature control panel. The temperature control panel controls the flow temperature acquisition controller for regulation.

[0058] Specific implementation method: Figure 1 The specific implementation method shown in the figure includes a large meter for a building, a flow temperature collection controller, an indoor temperature control panel, and a heat distribution device. The heat distribution device can read the Figure 2 The flow rate G, water supply temperature Tg, return water temperature Th, valve opening of the flow and temperature acquisition controller are shown to calculate the theoretical room temperature value. Figure 2 The actual room temperature value of the indoor temperature control panel is initially measured and distributed through the collected data. The heat distribution device can also collect Figure 3 The total heat of the building is shown , the heat of each branch is calculated through distribution.

[0059] A heating energy balance distribution and metering method involves balance regulation and heat metering distribution. In the early stage of heating, an initial flow value is set according to previous heating experience values, and then heat metering distribution is carried out under the flow value through the flow temperature acquisition controller and indoor temperature control panel installed in each household, combined with the unit large meter and heat distribution device installed in the unit building.

[0060] The heat metering distribution steps are as follows:

[0061] Step S1: Install a flow and temperature acquisition controller in each household. The device is equipped with a PT1000 temperature sensor, which can collect the supply water temperature value Tg and the return water temperature value Th. It is also equipped with a flow sensor, which uses ultrasonic measurement technology to provide water supply flow (G) data. Measure the supply water temperature Tg, return water temperature Th and supply water flow G of each household.

[0062] Step S2: Calculate the current theoretical room temperature value tn;

[0063] Heat transfer formula of thermodynamic cycle:

[0064]

[0065] Radiator heat dissipation formula:

[0066]

[0067] The heat transfer coefficient and heat dissipation area of ​​the radiator refer to the "Practical Heating and Air Conditioning Design Manual" (Second Edition), which stipulates different heat transfer coefficients and heat dissipation area calculations based on different properties such as material, pipe diameter, and size. When the invention method is implemented, KS and FS are generally set to fixed values ​​based on the installation conditions of the unit building. The average temperature is still collected by the flow temperature acquisition controller to collect the supply and return water temperature value (Tg / Th), and the average value of (Tg+Th) / 2 is regarded as the average temperature of the heat medium in the radiator.

[0068] Without considering the heat loss of the pipeline, the heat dissipated by the radiator should be equal to the heat provided by the hot water circulation. According to the thermodynamic principle Q1=Q2, the theoretical room temperature value Tn under the house structure and water supply flow rate can be calculated:

[0069] When the indoor temperature tends to be stable, the actual room temperature value Tc of each household is measured through the indoor temperature control panel. If the actual room temperature value Tc does not reach the indoor target temperature value, it is regulated according to the balance control strategy until the actual room temperature reaches the indoor target temperature value;

[0070] Step S3: Calculate the temperature coefficient Mt according to the actual room temperature value and the theoretical room temperature value: Mt=Tc / Tn;

[0071] Step S4: The flow temperature acquisition controller collects the water supply temperature value Tg, the return water temperature value Th, the water supply flow rate G, and the time t, which contains the MCU and the circuit, thereby calculating the flow temperature number;

[0072] The calculation formula of flow temperature number is:

[0073]

[0074] Step S5: Measure the total heat of the total pipeline through the unit meter , and thus calculate the heat of each branch pipe.

[0075] The calculation formula of the heat of the branch pipeline is:

[0076]

[0077] is the heat of the i-th pipeline; is the heat of the total pipeline; is the flow temperature number of the i-th pipeline.

[0078] The present invention provides a heating energy balance distribution metering method, which obtains the heat distribution value of each branch pipeline through heat metering distribution under the initial flow value state. However, since the indoor temperature corresponding to the initial flow may not meet the standard, it is necessary to perform balance regulation according to changes in the outdoor environment.

[0079] The balanced control mode is realized by collecting the water supply temperature and return water temperature through the flow temperature collection controller, and collecting the indoor temperature through the indoor temperature control panel; the flow temperature collection controller is installed on the heating pipeline of each user, and each unit is installed with a heat distribution device to collect the water supply temperature, return water temperature and indoor temperature of each household. The heat distribution device is connected to the remote control center by wireless communication. During control, the flow target value Gm of each user's pipeline is calculated based on the indoor target temperature and outdoor temperature, as well as the current indoor temperature, water supply temperature and return water temperature, and sent to the flow temperature collection controller. The flow rate is controlled according to the flow target value until the indoor temperature reaches the indoor target temperature after stabilization.

[0080] The steps of balance control are as follows:

[0081] Step S11: Obtain the weather conditions and the average outdoor temperature and temperature trend for the next 24 hours through the control center;

[0082] Step S12: The indoor temperature is collected through the indoor temperature control panel installed by the resident, and the indoor temperature is analyzed to determine whether it tends to be stable and the room temperature after stabilization. When the indoor temperature tends to be stable, the outdoor temperature obtained by the control center, the indoor temperature obtained by the indoor temperature control panel, and the inlet and return water temperature values ​​obtained by the flow temperature collection controller are used to calculate the "internal thermal temperature rise coefficient Wi of the resident's house" according to the calculation formula for the internal thermal temperature rise coefficient of the resident's house; the calculation formula for the internal thermal temperature rise coefficient of the resident's house is:

[0083]

[0084] is the current indoor temperature of the i-th heating user, in units of ; is the average temperature of hot water in the current radiator of the i-th heating user, in units of ; is the current heating temperature of the i-th heating user, in units of ; is the current return water temperature of the Ith heating user, in units of ; is the average outdoor temperature for heating, in .

[0085] Step S13: The indoor temperature of each household is collected and analyzed through the control center, and the reasonable indoor temperature target value of each household is obtained through statistics of the data center; the control center is the management and control platform of the heating company, and the heat metering and distribution will be managed and controlled by the management and control platform. The management and control platform can receive the room temperature and inlet and return water temperature values ​​of all households, and can obtain local weather conditions through the Internet, which is essential for the metering management and control of the heating company; the data center is the database carried by the management and control platform, and the current data and historical data of each household are stored in the database. The management and control platform of the control center can directly obtain the required relevant data.

[0086] Step S14: Calculate the target value of the average inlet and return water temperature of the branch pipe at the jth moment according to the internal heat rise coefficient Wi of the household house, the trend of outdoor temperature change, the target value of the indoor temperature and the acquisition time. ;

[0087] The target value calculation formula for the average inlet and return water temperature is:

[0088] ;

[0089] is the indoor target temperature of the i-th heating user at the j-th time; It is the average outdoor temperature predicted by the weather forecast for the i-th heating user at the j-th time.

[0090] Step S15: Obtain the average instantaneous heat value Qt based on the measured and corrected heat value Qi of each branch pipe, and then combine it with the target value of the average temperature of the inlet and return water at the jth moment , Total pipeline measurement value , find out the flow target value Gm of the current branch pipeline;

[0091] The flow target value calculation formula is:

[0092]

[0093] Step S16: The flow rate and temperature acquisition controller is adjusted according to the flow rate target value Gm until the flow rate target value is reached; after the indoor temperature tends to be stable, it is determined whether the indoor target temperature has been reached. If not, the heat metering S11 to S15 are repeated until the indoor target temperature is reached.

[0094] When the indoor temperature reaches the target temperature and tends to be stable, the heat metering distribution in the equilibrium state is performed. The heat metering distribution steps S2 to S4 are continued, and the final heat value Qi is the final heat metering value.

[0095] A heat supply energy balance distribution metering method of the present invention performs balance regulation according to a set room temperature target value, and performs final heat metering after reaching a balance state, and the metering data obtained is more accurate.

[0096] The theoretical basis of the heat supply energy balance distribution measurement method of the present invention relates to the building enclosure structure such as Figure 4 The basic research model involves the heat transfer formula of the thermodynamic cycle, the heat dissipation formula of the radiator and its corresponding derivation formula and theory, etc., from which the theoretical room temperature value under the structure of the house and the heating mode can be calculated.

[0097] Compare the theoretical room temperature value with the actual room temperature value to obtain the temperature coefficient, which can reflect the heat loss and heat gain of the room. If the heat loss is greater than the heat gain, then the theoretical room temperature value should be greater than the actual room temperature value, such as some corner households. If the heat loss is less than the heat gain, then the theoretical room temperature value should be less than the actual room temperature value, such as the middle household.
