Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

For the convenience of understanding the present embodiment, a method for automatically adjusting the hydraulic balance of the heating secondary pipe network disclosed in the embodiments of the present application will be described in detail first.

Example one

The embodiment of the application discloses a method for automatically adjusting hydraulic balance of a heat supply secondary pipe network, which is applied to the heat supply secondary pipe network in the heat supply industry and a heat supply system in a building.

As shown in fig. 1, a method for automatically adjusting the hydraulic balance of a heating secondary pipe network disclosed in an embodiment of the present application includes:

s101: and acquiring standard square meter flow and actual square meter flow of each building.

According to different use scenes, different methods can be used for acquiring the standard square meter flow, and specifically, the standard square meter flow is acquired, including at least one of the following two embodiments:

calculating to obtain standard square meter flow according to the actual square meter flow of all buildings; and acquiring the preset standard square meter flow.

Here, the standard square meter flow is calculated according to the actual square meter flow of all buildings, and the method comprises the following steps: acquiring actual square meter flow of all buildings; and calculating the average value of the actual square meter flow of all buildings to obtain the standard square meter flow.

When hydraulic balance adjustment is carried out on all buildings in the heat supply secondary pipe network, a method of calculating according to actual square meter flow of all the buildings is adopted to obtain standard square meter flow.

Aiming at the heat supply secondary pipe network which achieves hydraulic balance through adjustment, the heat supply amount of the secondary pipe network and the power consumption of a circulating pump can be reduced through a mode of reducing the square meter flow of the whole heat supply secondary pipe network, specifically for example, the standard square meter flow which is smaller than the current square meter flow is set for the heat supply secondary pipe network which achieves hydraulic balance through adjustment of the method in the embodiment of the application, and the heat consumption and the power consumption of the heat supply secondary pipe network can be integrally reduced on the premise of ensuring that the heat supply temperature reaches the standard.

The actual square meter flow of each building can be obtained by using a flow collector, the actual flow of each building entrance is obtained by the flow collector, and the actual square meter flow of each building can be obtained by calculating according to the actual flow of each building and the heat supply area of each building.

S102: and selecting at least one building corresponding to the maximum actual square meter flow from the buildings with the actual square meter flow larger than the standard square meter flow to obtain at least one building to be regulated.

In actual implementation, when the actual square meter flow of all buildings in the heat supply secondary pipe network reaches the preset adjusting range, all buildings in the heat supply secondary pipe network can be considered to reach the hydraulic balance state. The preset adjusting range comprises: the actual square meter flow of all buildings in the heat supply secondary pipe network is larger than a first preset threshold value, and the actual square meter flow of all buildings in the heat supply secondary pipe network is smaller than a second preset threshold value. Preferably, the first preset threshold value floats upwards by 5% -10% on the basis of the standard square meter flow rate, and the second preset threshold value floats upwards by 5% -10% on the basis of the standard square meter flow rate.

Therefore, selecting the building to be adjusted further comprises: determining an upper regulation limit based on the standard square meter flow and a preset regulation range; selecting at least one building corresponding to the maximum actual square meter flow from the buildings with the actual square meter flow larger than the standard square meter flow; and screening the buildings larger than the adjustment upper limit from the selected buildings to obtain the buildings to be adjusted.

Here, the upper adjustment limit is a second preset threshold, and the lower adjustment limit is a first preset threshold.

In a specific implementation, for example, the first preset threshold value is 5% of the standard square meter flow rate, and the second preset threshold value is 5% of the standard square meter flow rate. The preset adjusting range is 5% of downward floating on the basis of standard square meter flow to 5% of upward floating on the basis of standard square meter flow, and the upper adjusting limit is 5% of upward floating on the basis of standard square meter flow. Therefore, selecting the building to be adjusted further comprises: selecting at least one building corresponding to the maximum actual square meter flow from the buildings with the actual square meter flow larger than the standard square meter flow; and screening the buildings larger than the upper regulation limit from the selected buildings, for example, screening the buildings with the actual square meter flow rate larger than 5% of the standard square meter flow rate, and obtaining the buildings to be regulated.

S103: and acquiring the valve closing proportion of each building to be regulated.

In the prior art, the resistance of all buildings in a heat supply secondary pipe network is adjusted by manually adjusting a valve laid at the building opening of the building to be adjusted in the heat supply secondary pipe network, and the aim is to make the resistance of all buildings in the heat supply secondary pipe network consistent, so that the hydraulic balance of the heat supply secondary pipe network is achieved. However, in the actual implementation process, the manual adjustment workload is large, and due to the fact that a large difference exists between the designed square meter flow of many buildings and the actual square meter flow which can be achieved after actual construction, the adjustment requirement exceeds the adjustment upper limit of the building entrance valve. Therefore, the adjustment mode in the prior art often cannot achieve the purpose of enabling the resistance of all buildings in the heat supply secondary pipe network to be consistent, so that the hydraulic balance of the heat supply secondary pipe network cannot be achieved.

Different from prior art, this application embodiment carries out the hydraulic balance adjustment of heat supply secondary pipe network through the mode of obtaining the shut-off valve proportion of every building of treating to adjust. By utilizing the method provided by the embodiment of the application, the valve closing proportion of each building to be regulated is automatically obtained, the valve closing proportion of each building to be regulated can be flexibly determined according to the actual square meter flow of all the buildings in the heat supply secondary pipe network and the actual situation, the limitation of the regulation upper limit of the existing building entrance valve is avoided, and therefore the hydraulic balance of the heat supply secondary pipe network can be achieved, and the hydraulic balance of the heat supply secondary pipe network can be regulated in real time.

Here, in the specific implementation, since the laying range of the heat supply secondary pipe network is at least one cell, the laying range of the heat supply secondary pipe network is relatively wide, the distance between the buildings is relatively long, the heat supply secondary pipe network is a communicated dynamic balance system, and the hydraulic balance adjustment process of the building to be adjusted can affect the actual flow per square meter of all the buildings in the heat supply secondary pipe network. Therefore, when the building to be adjusted in the heat supply secondary pipe network is adjusted each time, the calculation of the valve closing proportion is complex, and a plurality of factors to be considered include the difference value between the actual square meter flow and the standard square meter flow of the building to be adjusted, the position of the building to be adjusted in the heat supply secondary pipe network and the like. In addition, in the implementation process, an accurate valve closing ratio may not be obtained through calculation. Therefore, obtaining the valve closing ratio includes at least one of the following two embodiments:

acquiring a prefabricated minimum valve closing proportion, and taking the prefabricated minimum valve closing proportion as the valve closing proportion of each building to be regulated; and determining the valve closing proportion of each building to be regulated respectively based on the difference value between the actual square meter flow and the standard square meter flow of each building to be regulated.

Because the laying range of the heat supply secondary pipe network is wider, when each building to be regulated of the heat supply secondary pipe network is subjected to hydraulic balance regulation, the feedback of the regulation result is not very timely, and the heat supply secondary pipe network can be balanced again only by waiting for a certain time after the building to be regulated is subjected to hydraulic balance regulation every time.

Therefore, every time a predetermined period of time passes, for example, every 30 minutes, it is necessary to acquire the current actual square meter flow rate of each building and determine whether the current actual square meter flow rate of each building is within the preset regulation range. If the current actual square meter flow of each building is within the preset adjusting range, the heat supply secondary pipe network achieves hydraulic balance; if buildings with current actual flow in square meters out of the preset adjusting range exist, the buildings to be adjusted need to be obtained again, a new valve closing proportion is determined, new user groups of the buildings to be adjusted are obtained based on the new valve closing proportion, and valve closing processing is carried out on each user group in sequence based on the preset valve closing duration.

Here, obtaining a preset minimum shut-off valve ratio and taking the preset minimum shut-off valve ratio as a shut-off valve ratio of each building to be regulated, further includes: obtaining the current valve closing proportion and the current actual flow per square meter of each building after a preset time period; under the condition that buildings with current actual square-meter flow larger than the standard square-meter flow exist, at least one building corresponding to the largest current actual square-meter flow is selected from the buildings with the current actual square-meter flow larger than the standard square-meter flow, and at least one new building to be adjusted is obtained; determining a new valve closing proportion according to the current valve closing proportion and the preset minimum valve closing proportion; acquiring a new user group of each new building to be regulated based on the new valve closing proportion; and for each new building to be adjusted, sequentially closing the valve of each new user group based on the preset valve closing duration.

Here, determining the valve closing proportion of each building to be adjusted based on the difference between the actual square meter flow and the standard square meter flow of each building to be adjusted respectively, further comprises: acquiring the current actual square meter flow of each building after a preset time period; under the condition that buildings with current actual square-meter flow larger than the standard square-meter flow exist, at least one building corresponding to the largest current actual square-meter flow is selected from the buildings with the current actual square-meter flow larger than the standard square-meter flow, and at least one new building to be adjusted is obtained; under the condition that the new building to be regulated has a relevant valve proportion before the preset time period, acquiring a valve closing proportion of the new building to be regulated before the preset time period, determining the new valve closing proportion of the new building to be regulated according to the acquired valve closing proportion and a preset minimum valve closing proportion, acquiring a new user group of the new building to be regulated based on the new valve closing proportion, and sequentially performing valve closing processing on each new user group based on the preset valve closing duration; and under the condition that the new building to be regulated does not have a relevant valve proportion before the preset time period, taking the prefabricated minimum valve closing proportion as the valve closing proportion of the new building to be regulated, acquiring a user group of the new building to be regulated based on the valve closing proportion, and sequentially performing valve closing processing on each user group based on the preset valve closing duration.

S104: acquiring a user group of each building to be regulated based on the valve closing proportion of each building to be regulated; wherein the user group includes at least one user.

In order to adjust the hydraulic balance of the whole heat supply secondary pipe network, the adjustment of vertical heat balance in a building is also very important, and the vertical heat balance in the building is adjusted mainly by adjusting the opening of a ball valve at a single inlet or the opening of a tail end balance valve by a user in the prior art. However, at present, no reasonable detection and judgment basis for vertical heat balance in a building exists, the adjustment is mainly carried out by depending on the feeling of residents, and the vertical heat imbalance in the building can be caused by the conventional adjustment mode that a user adjusts the heat balance in the building by the aid of the opening degree of a ball valve at a single door entrance or the opening degree of a balance valve at the tail end.

According to the method, users in each building to be regulated are reasonably grouped, and the vertical heat balance in the building is achieved while the hydraulic balance of the heat supply secondary pipe network is achieved.

The principle of grouping users is the principle of heat transfer between the users of residential buildings, and on this basis, the method of the embodiment of the present application further includes the step of determining the user group:

acquiring the grouping number corresponding to the valve closing proportion; and dividing the users in the building into the user groups with the number of the groups based on the spatial position of each user in the building and the heat dissipation parameter of each user in the building.

It should be noted that different off valve ratios correspond to different numbers of groups, and the number of groups may be set for each off valve ratio before the method of the present embodiment is performed, and users within the building may be grouped according to the different numbers of groups. When the method of the embodiment is executed, only the corresponding user group needs to be acquired according to the current valve closing ratio.

Here, dividing the users in the building into the user groups of the number of groups includes: dividing users with non-adjacent spatial positions into the same user group; dividing users with heat dissipation parameters in the same numerical value interval into different user groups; users located in the same floor and in the same direction are classified into different user groups; users at the same horizontal position on different floors are grouped into different user groups.

Here, the method further comprises the step of determining the heat dissipation parameter: and determining the heat dissipation parameters of the user based on the number of the heat dissipation surfaces and the number of the heat transfer surfaces of the user. Specifically, the heat dissipation surface refers to a wall surface between the user and the outside air; the heat transfer surface is a wall surface between two adjacent users.

The above-mentioned valve-closing ratio can be expressed in percentages, for example comprised between 0% and 100%.

To better describe the method of user grouping, specifically, as shown in fig. 2, the building to be conditioned includes a building of units of 5 units, each unit including 6 floors, each floor including 2 users, and a total of 60 users. And acquiring the grouping number corresponding to the valve closing ratio, for example, if the valve closing ratio is 10%, the proportion of the user number in each user grouping in the total user number is 10%, and the grouping number is 10 groups. Dividing users in a building into user groups with the group number, specifically, in a common residential building with the total number of 60 users as shown in fig. 2, the group number is 10, the number of users in each user group is 6, and dividing users with non-adjacent spatial positions into the same user group; dividing users with heat dissipation parameters in the same numerical value interval into different user groups; users located in the same floor and in the same direction are classified into different user groups; users at the same horizontal position on different floors are grouped into different user groups.

In a general residential building having a total number of 60 households as shown in fig. 2, the number of users in each user group corresponding to 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100% of the valve-closing ratio is: 6, 12, 18, 24, 30, 36, 42, 48, 54 and 60 households. And dividing users whose spatial positions are not adjacent into the same user group; dividing users with heat dissipation parameters in the same numerical value interval into different user groups; users located in the same floor and in the same direction are classified into different user groups; users at the same horizontal position on different floors are grouped into different user groups.

Since some users may have their heating valves in a long-term closed state when the valve closing ratio is greater than 50%, and thus some users may have their heating disconnected state when the embodiment of the present application is actually implemented, it is preferable that the valve closing ratio is less than or equal to 50%. Table 1 gives examples of the grouping results when the valve-closing ratio is 10%, 20%, 30%, 40%, and 50% in the general residential building having the total number of 60 households shown in fig. 2.

Table 1 examples of grouping results

S105: and for each building to be adjusted, sequentially performing valve closing processing on each user group based on the acquired preset valve closing duration.

Here, the preset valve-closing time period is set under the condition that the users subjected to the valve-closing process are grouped within the time range of the valve-closing time period without experiencing a significant temperature drop.

Here, the preset valve-closing time period may be set to the same time period, or a different valve-closing time period may be set for each user group. The specific valve closing time length can be determined according to the space position of each user grouping group and the heat dissipation parameter, and can also be set to an empirical value.

Here, as shown in fig. 3, the valve closing process is performed for each user group in turn, and the heating valves of each user group are closed in turn according to the valve closing ratio and the valve closing duration cycle. Specifically, taking an ordinary residential building with a total number of 60 users as shown in fig. 2 as an example of a building to be adjusted, assuming that a valve closing proportion is 10%, and a valve closing time is 30 minutes, the number of groups is 10, the number of users in each user group is 6, for each building to be adjusted, the heating valves of the 1 st group of users are closed for 15 minutes, then the heating valves of the 1 st group of users are opened, the heating valves of the 2 nd group of users are closed for 10 minutes, and so on, the heating valves of each user group are closed in sequence, until the heating valves of the 10 th group of users are closed for 5 minutes, the heating valves of the 10 th group of users are opened, and the heating valves of the 1 st group of users are closed for 15 minutes.

Table 2 gives a specific example of the valve closing time period when the building to be regulated is a general residential building with a total number of 60 households as shown in fig. 2.

TABLE 2 example shut-off duration for each set

The embodiment of the application is based on the obtained valve closing proportion and the preset valve closing duration, the heating valves grouped by each user are closed in sequence in a circulating mode, the resistance of each building to be adjusted can be adjusted through the valve closing proportion, so that the resistance of each building in the heating secondary pipe network is consistent, the hydraulic balance of the heating secondary pipe network is achieved, the heating valves grouped by each user are closed in sequence in the circulating mode, and the vertical heat balance in the building to be adjusted is achieved. According to the embodiment of the application, the building to be adjusted is determined according to the standard square meter flow and the actual square meter flow of each building, and the resistance of the building to be adjusted is adjusted based on the valve closing proportion and the preset valve closing duration, so that the aims of automatically adjusting the hydraulic balance and the vertical heat balance of the heat supply secondary pipe network are fulfilled.

s401: and acquiring the current valve closing proportion and the current actual square meter flow of each building every preset time period.

Because the laying range of the heat supply secondary pipe network is wider, when each building to be regulated of the heat supply secondary pipe network is subjected to hydraulic balance regulation, the feedback of the regulation result is not very timely, and the heat supply secondary pipe network can be balanced again only by waiting for a certain time after the building to be regulated is subjected to hydraulic balance regulation every time. Therefore, every time a predetermined period of time passes, for example, every 30 minutes, it is necessary to acquire the current actual square meter flow rate of each building and determine whether the current actual square meter flow rate of each building is within the preset regulation range.

Here, the actual square meter flow of each building can be obtained using a flow collector, for example, a flow meter that is already currently installed at the building entrance.

S403: and selecting at least one building corresponding to the maximum actual square meter flow from the buildings with the actual square meter flow larger than the standard square meter flow to obtain at least one building to be regulated.

In actual implementation, when the actual square meter flow of all buildings in the heat supply secondary pipe network reaches the preset adjusting range, all buildings in the heat supply secondary pipe network can be considered to reach the hydraulic balance state. Therefore, selecting the building to be adjusted further comprises: determining an upper regulation limit based on the standard square meter flow and a preset regulation range; selecting at least one building corresponding to the maximum actual square meter flow from the buildings with the actual square meter flow larger than the standard square meter flow; and screening the buildings larger than the adjustment upper limit from the selected buildings to obtain the buildings to be adjusted.

S404: acquiring the valve closing proportion of each building to be regulated, and acquiring the user group of each building to be regulated based on the valve closing proportion of each building to be regulated; wherein the user group includes at least one user.
