Furthermore, the term "connection" here includes any direct or indirect means of connection.

[0045] like Figure 1 and Figure 2As shown, the residential building heating system of this utility model includes a heat exchanger 100. The primary side of the heat exchanger 100 is connected to a primary supply and return water pipeline 200, and the secondary side of the heat exchanger 100 is connected to a secondary supply and return water pipeline 300. The heat exchanger 100 is commonly a plate heat exchanger. The residential building heating system of this utility model also includes a building supply and return water pipeline 400 and multiple unit user supply and return water pipelines 500. The building supply and return water pipeline 400 is connected to the secondary supply and return water pipeline 300, and multiple unit user supply and return water pipelines 500 are connected in parallel to the building supply and return water pipeline 400. The building supply and return water pipeline 400 is used to connect the secondary supply and return water pipelines 300 to each unit user supply and return water pipeline 500. The multiple unit user supply and return water pipelines 500 are connected to the secondary supply and return water pipeline 300 through the building supply and return water pipeline 400 to achieve heating circulation.

[0046] The residential building heating system of this utility model also includes a water replenishment system 301. The secondary supply and return water pipeline 300 includes a secondary supply water pipe 310 and a secondary return water pipe 320, with the water replenishment system 301 connected to the secondary return water pipe 320. The water replenishment system 301 is equipped with an online water quality monitoring device to monitor the water quality of the secondary side replenishment water in real time. The secondary side water quality is periodically monitored to ensure that the water quality requirements of the heat meter and regulating valve are met.

[0047] The primary supply and return water pipeline 200 includes a primary supply water pipe 210 and a primary return water pipe 220. The residential building heating system of this invention also includes a primary electric differential pressure balancing valve 201 and an electric regulating valve 202 connected to the primary supply water pipe 210. Additionally, the residential building heating system of this invention also includes a primary side heat meter 203 installed on the primary return water pipe 220.

[0048] The building water supply and return pipeline 400 includes a building water supply pipe 410 and a building return pipe 420. The residential building heating system of this utility model also includes a building electric differential pressure balancing valve 401 and a building heat meter 402 installed on the building water supply pipe 410.

[0049] The residential building heating system of this utility model also includes a temperature collector 302 and a secondary heat meter 303 installed on the secondary water supply pipe 310.

[0050] The residential building heating system of this utility model also includes a circulation pump 304, which is installed on the secondary return water pipe 320.

[0051] Multiple heat users 600 are connected in parallel on the supply and return water pipes 500 of each heat user unit. A household heat meter 601 is installed at the heat inlet of the heat user 600, a thermostatic valve 602 is installed at the inlet of each group of radiators of the heat user 600, and an indoor temperature sensor 603 is installed in the room of the heat user 600 at a location that can accurately reflect the room temperature of the user.

[0052] When a heat user 600 adjusts the indoor temperature according to the weather or personal needs, the thermostatic valve 602 automatically adjusts the water supply flow of the heat user. The water supply flow of the building changes according to the changes in the flow of each heat user, and the building electric differential pressure balancing valve 401 automatically adjusts to maintain the hydraulic balance of each building.

[0053] When the building's water supply flow rate changes, the secondary water supply flow rate of the heat exchange station also changes. The frequency of the circulating pump 304 is automatically adjusted to maintain the pressure difference between the secondary supply and return water pipes. At the same time, when the temperature of the secondary water supply pipe of the heat exchange station changes, the opening of the electric regulating valve 202 is automatically adjusted to maintain the temperature of the secondary water supply pipe.

[0054] When the opening of the electric regulating valve 202 changes, the primary return water flow rate changes, and the primary electric differential pressure balancing valve 201 automatically adjusts to maintain the hydraulic balance on the primary side of each heat exchange station.

[0055] Household heat meter 601 collects the heat consumption of individual users, building heat meter 402 collects the heat consumption of the entire building, secondary heat meter 303 collects the secondary heat consumption of heat exchanger 100, and primary heat meter 203 collects the primary heat consumption of heat exchanger 100. This system, by installing heat meters at the heat exchange station, in buildings, and on the supply and return water pipes of individual users, can calculate the thermal efficiency of heat exchanger 100, the heat loss of the community heating network, the heat loss of buildings, and the thermal efficiency of buildings, thus providing a basis for implementing heat metering and billing.

[0056] This system enables users to adjust room temperature in real time, maintain hydraulic balance in buildings and heat exchange stations, and adjust heating supply in real time according to user heat consumption, thereby reducing heating energy consumption on the user side. It should be noted that the control strategies of this utility model are based on existing automatic control technologies and are not within the scope of protection of this utility model. This utility model focuses on the modification of the system piping.

[0057] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
