[0001] The present invention relates to the field of heating technology, and in particular to a heating method, system, equipment and storage medium for heat balance. Background Art

[0002] The heating system is usually divided into urban centralized heating system and distributed centralized heating system. The heating system involves three parts: heat source system, heat medium transmission and distribution system and terminal heat dissipation system. The heat medium transmission and distribution system is divided into heat medium transmission part and heat medium distribution part. The heat medium distribution part needs to realize the distribution of heat to each heat user on demand. Taking a newly built 100,000 square meters community as an example, the total heat demand of the community buildings under the design conditions is about 3000kw. Since the actual heat demand of each heat user is different, how to realize the heat distribution on demand for each heat user is particularly critical. For a heat user, if the allocated heat exceeds the actual heat demand of the heat user, the user's temperature will be too high, resulting in energy waste. If the allocated heat is less than the actual heat demand of the heat user, the user's temperature will be too low, the heating quality will not meet the standard, and user complaints will be generated. Therefore, how to distribute heat to each heat user on demand, that is, to achieve the thermal balance of the heating system, is the key to the system to ensure heating quality and efficient energy-saving operation. Summary of the invention

[0003] In view of the above problems existing in the prior art, the present invention provides a heat supply method, system, equipment and storage medium for heat balance to improve the existing situation where the actual heat demand of heat users and the allocated heat are uneven.

[0004] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present invention provides a heat supply method for heat balance, comprising: obtaining the heating type and design parameters of the heat user; obtaining the initial heat load demand of the heat user according to the heating type and design parameters of the heat user; obtaining the pre-opening of the valve of the heat user according to the initial heat load demand; obtaining the real-time indoor temperature of the heat user; and controlling the real-time opening of the valve of the heat user according to the real-time indoor temperature of the heat user.

[0005] In an exemplary embodiment of the present invention, the heat supply type includes the geographical location of the heat user, the surrounding heat usage status, and the free heat gain of the heat user.

[0006] In an exemplary embodiment of the present invention, the following steps are included: uploading the real-time indoor temperature of the heat user to a cloud platform; obtaining the compliance status of the heating area according to the real-time temperature of the heat user in the area; and adjusting the supply and return water temperatures of the heat source according to the compliance status of the heating area.

[0007] In an exemplary embodiment of the present invention, before the step of obtaining the heating type and design parameters of the heat user, it includes: matching the heating type and design parameters of the heat user with the account number of the heat user; matching the valve and room temperature collector with the account number of the heat user.

[0008] In an exemplary embodiment of the present invention, the design parameters include basic HVAC data of heat users.

[0009] In an exemplary embodiment of the present invention, the real-time opening of the valve of the heat user is controlled according to the real-time indoor temperature of the heat user, including: obtaining the difference between the real-time indoor temperature of the heat user and the expected temperature; and adjusting the real-time opening of the valve according to the difference.

[0010] In an exemplary embodiment of the present invention, the real-time opening of the valve of the heat user is controlled according to the real-time indoor temperature of the heat user, including: obtaining the average indoor temperature of the heat user according to the real-time indoor temperature of the heat user; obtaining the difference between the average indoor temperature of the heat user and the expected temperature; and adjusting the real-time opening of the valve according to the difference.

[0011] The second aspect of the present invention provides a heat supply balanced heating system, comprising: an information acquisition module, used to obtain the heating type and design parameters of the heat user; an initial heat load calculation module, used to obtain the initial heat load demand of the heat user according to the heating type and design parameters of the heat user; a valve pre-opening acquisition module, used to obtain the valve pre-opening of the heat user according to the initial heat load demand; a room temperature acquisition module, used to obtain the indoor real-time temperature of the heat user; a valve control module, used to control the real-time opening of the valve of the heat user according to the indoor real-time temperature of the heat user.

[0012] The third aspect of the present invention provides a device, which includes: one or more processors; a storage device for storing one or more programs, when the one or more programs are executed by the one or more processors, the device implements the heat supply method for heat balance as described in any one of the above.

[0013] A fourth aspect of the present invention provides a readable storage medium having a computer program stored thereon, which, when executed by a processor of a computer, enables the computer to execute any one of the above-described heat supply methods for heat supply balance.

[0014] In combination with the prior art, the beneficial effects of the present invention are:

[0015] The existing heating system's heat distribution does not match the actual heat demand, resulting in the user's temperature being too high or too low, affecting the heating quality and heating energy saving. Before the start of heating, the present invention obtains the initial heat load demand of the heat user according to the heating type and design parameters, and determines the valve pre-opening according to the initial heat load demand, thereby reducing the difference between the actual heat supply and the required heat at the start of heating. On the one hand, it can ensure the heating quality, and on the other hand, it can reduce heat waste, avoid energy waste, and effectively achieve the heat balance at the initial heating. At the same time, by accurately allocating the initial heat supply, the amplitude of the subsequent correction of the heat supply according to the indoor temperature is reduced, thereby effectively reducing the oscillation of the heating system and improving the stability of the heating system.

[0016] By controlling the real-time opening of the indoor temperature of heat users, we can effectively obtain the impact of external energy on the indoor environment of heat users, such as heat emitted by indoor electrical appliances, human body, cooking, bathing, etc., as well as solar energy that illuminates buildings, etc. By effectively monitoring and utilizing external energy, we can reduce the equipment configuration at the heat source end and lower the initial investment.

[0026] The heat medium transmission and distribution system is divided into the heat medium transmission part and the heat medium distribution part. The heat medium distribution part needs to realize the distribution of heat to each heat user on demand. Taking a newly built community of 100,000 square meters as an example, the total heat demand of the community buildings under the design conditions is about 3000kw. Due to the different geographical locations of each heat user, the heat usage status of nearby heat users, the different internal free heat gain of heat users, and the different solar heat gain of heat users, the actual heat demand of each user is different. Therefore, how to realize the heat distribution on demand for each heat user is particularly critical. For a heat user, if the allocated heat exceeds the actual heat demand of the heat user, the user's temperature will be too high, resulting in energy waste. If the allocated heat is less than the actual heat demand of the heat user, the user's temperature will be too low and the heating quality will not meet the standards, resulting in user complaints.

[0027] In view of this, the first aspect of the present invention provides a heat supply method with heat balance to calculate the actual heat demand of each heat user, and to distribute the heat to each heat user as needed, while monitoring the actual temperature of each heat user, and realizing automatic thermal balance of the system through closed-loop correction control.

[0028] See also Figure 1 The heat supply method of heat balance specifically includes the following steps:

[0029] Step S110, obtaining the heating type and design parameters of the heat user;

[0030] The heating type includes the geographical location of the heat user, the surrounding heat usage status, and the free heat gain of the heat user. For example, the heat user is an intermediate household or an edge household, and the insulation effects that need to be considered for intermediate households and edge households are different; the surrounding heat usage status includes whether the surrounding users of the heat user are heated, such as heating for one surrounding user or heating for two surrounding users, etc.; the free heat gain of the heat user includes the absorbed solar heat, etc.

[0031] The design parameters include the basic HVAC data of heat users, which have been designed at the beginning of the building design and can be obtained through querying relevant databases.

[0032] In order to ensure that the heating type, design parameters, valves, and room temperature collection modules match, at the beginning of the operation of the heating system, the heating type and design parameters of the heat user are first matched with the household number of the heat user, and then the valves and room temperature collectors are matched with the household number of the heat user.

[0033] In one embodiment, the status of users surrounding the heat user is automatically identified based on the heat user's account number, and then the heat supply type of the heat user is automatically matched and obtained.

[0034] In one embodiment, the valve adopts an electric self-operated flow valve, including a valve body and an actuator. The valve body uses a self-operated flow valve, which has a constant flow function between a pressure difference of 20kpa and 300kpa. The flow regulation of each heat user will cause the pressure difference of the pipeline network to change. If an ordinary ball valve is used, the change of the pressure difference of the pipeline network will affect the flow of each heat user, causing the allocated heat of each heat user to change. This mutual influence will cause the system to oscillate and become unregulated. The application of a self-operated flow valve effectively avoids the influence of the pressure difference of the pipeline network on the flow of heat users, so the application of a self-operated flow valve is the basis for achieving the thermal balance of the system. The actuator adopts a three-module design, in which the communication linkage with the room temperature collector adopts a LORA module, which has the advantages of stable short-distance communication signals and no flow charges; the communication linkage with the platform server adopts a 4G module, which has the advantages of stable long-distance communication signals and strong real-time communication capabilities; the communication linkage with the local debugging device adopts a Bluetooth module, which has the advantages of stable short-distance communication signals and flexible methods.

[0035] In one embodiment, the communication linkage between the room temperature collector and the electric self-operated flow valve adopts the LORA module to ensure the stability of the short-distance communication signal and no flow fee. The room temperature collector is installed in the room of the heat user, and can collect the real-time temperature of the room of the heat user in real time, and feed back the temperature to the electric self-operated flow valve of the total return water pipe of the heat user. The flow valve adjusts the opening according to the temperature feedback to ensure the stability of the room temperature and ensure that the room temperature is controlled within the initial temperature range.

[0036] Step S120: obtaining the initial heat load demand of the heat user according to the heat supply type and design parameters of the heat user.

[0037] According to the basic design parameters of the building HVAC drawings and the heating type of the heat user, the heating load of the heat user is designed and reset to obtain the initial heat load demand of the heat user. The basic design parameters of the building HVAC drawings include the basic heat load, and the required increase in heat load is obtained through the status of the users around the heat user. The initial heat load of the heat user is obtained through the influence of the basic heat load and the status of the surrounding users and the influence of the free heat gain.

[0038] Step S130, obtaining the valve pre-opening degree of the heat user according to the initial heat load demand;

[0039] According to the initial heat load and the designed inlet and return water temperature of the heat source, the valve pre-opening of the heat user is obtained, and the valve pre-opening result is sent to the valve of each heat user, such as an electric self-operated flow valve.

[0040] By obtaining the valve pre-opening, the initial heat of heating can be made closer to the actual heat load of the heat user, thereby reducing heat energy loss in the initial stage of heating, that is, under the premise of ensuring heating quality. By obtaining the accurate valve pre-opening, the indoor temperature of the heat user can be close to the expected temperature, which is convenient for adjusting the heat source, effectively reducing the vibration of the heating system, and improving the stability of the heating system.

[0041] Step S140: obtaining the real-time indoor temperature of the heat user.

[0042] The real-time indoor temperature can be obtained through a pre-installed room temperature collector, which can be pre-installed on the indoor heating panel for easy installation and monitoring. The room temperature collector can effectively monitor the changes in the indoor temperature of the heat user. The indoor temperature changes caused by external free energy can be timely and effectively acted on the electric self-operated flow valve installed in the user's pipeline. This part of free energy is used to greatly reduce the energy consumption during the heating season. External energy includes but is not limited to the heat emitted by the human body, electrical appliances, cooking, bathing, etc. in the room, as well as the solar energy that shines on the building during the day.

[0043] Step S150: controlling the real-time opening of the valve of the heat user according to the real-time indoor temperature of the heat user.

[0044] By comparing the real-time indoor temperature with the preset temperature, the difference between the real-time indoor temperature and the expected temperature of the heat user is obtained, and the real-time opening of the valve is adjusted according to the difference. By directly feeding back the difference to the valve, the real-time opening of the valve is adjusted so that the real-time indoor temperature is the same or close to the preset temperature, so that the allocated heat matches the actual heat demand of the heat user, effectively ensuring the heating quality of the heat user, the stable operation of the system, and the accuracy of on-demand heat allocation. The heating operation and maintenance during the heating season has been automated, reducing the additional energy consumption caused by the uncertainty brought about by manual operation, and effectively reducing energy consumption during the heating season.

[0045] In one embodiment, controlling the real-time opening of the valve of the heat user according to the real-time indoor temperature of the heat user also includes obtaining the current inlet water temperature, and adjusting the real-time opening of the valve according to the difference between the real-time indoor temperature and the preset temperature in combination with the current inlet water temperature, so as to more quickly and accurately control the real-time indoor temperature, so that the real-time indoor temperature is consistent or substantially consistent with the preset temperature.

[0046] See also Figure 3 In another embodiment, controlling the real-time opening of the valve of the heat user according to the real-time indoor temperature of the heat user comprises:

[0047] Step S310: Obtain the average indoor temperature of the heat user according to the real-time indoor temperature of the heat user.

[0048] The real-time indoor temperature of heat users will vary due to the different locations of temperature collectors. For example, the temperature of north-facing rooms is usually lower than that of south-facing rooms, and the temperature of rooms close to the exterior wall of a building is lower than that of rooms close to the interior wall of a building. By setting up multiple temperature collectors, the average indoor temperature can be obtained, and the heating quality can be better evaluated by the indoor average temperature.

[0049] Step S320: Obtain the difference between the indoor average temperature and the expected temperature of the heat user.

[0050] A more accurate heat differential can be obtained based on the difference between the average indoor temperature and the expected temperature.

[0051] Step S330: adjusting the real-time opening of the valve according to the difference.

[0052] The real-time opening of the valve is adjusted according to the difference between the average indoor temperature and the expected temperature, so that the actual indoor temperature is consistent with the expected temperature.

[0053] In order to obtain better heating quality and improve the satisfaction of heat users, after obtaining the real-time temperature of the heat user, the supply and return water temperatures of the heat source are adjusted by feedback. Figure 2 , the specific steps are as follows.

[0054] Step S210: Upload the real-time indoor temperature of the heat user to the cloud platform.

[0055] The cloud platform server is set up at the company's headquarters. The information parameters of the hardware equipment are uploaded to the cloud platform, and the real-time indoor temperature is uploaded to the cloud platform to improve the management and control of the actual heat required by heat users.

[0056] Step S220: Obtain the compliance status of the heating area according to the real-time temperature of the heat users in the area.

[0057] The residential area can be used as the heating area, or other areas can be demarcated as needed. Based on the real-time temperature of heat users in the area, it can be determined whether the total required heat in the area is consistent with the actual heat supplied.

[0058] In one embodiment, the compliance of the heating area can be judged based on the compliance ratio, for example, the ratio of the number of households whose indoor temperature is not lower than the expected temperature to the total number of households in the heating area is evaluated to determine whether the area as a whole meets the standard.

[0059] Step S230: adjusting the supply and return water temperatures of the heat source according to the compliance of the heating area.

[0060] The main pipeline supply temperature at the heat source end is corrected according to the compliance of the heating area, effectively ensuring the heating quality for heat users.
