Description

Technical Field

[0001] This invention relates to the field of heating network temperature control technology, and specifically provides a smart heating temperature control system. Background Technology

[0002] Central heating is safer and more environmentally friendly than individual household heating, and is the main way for urban residents to keep warm in winter. Central heating provides heat all day long, but the temperature is uneven due to different floors. If the heating is too hot, residents can only open windows to cool down, wasting precious energy; if the heating is too cold, they can only supplement it themselves by using air conditioning or other means.

[0003] With technological advancements, heating companies have begun using heating management systems to manage heating networks, resulting in more uniform and comfortable indoor temperatures for residents. These systems typically regulate the hydraulic pressure in the secondary network, either at the user end (e.g., the inlet valve) or by installing regulating valves in the building. However, these valves are currently manually adjustable, and the user's temperature cannot be automatically monitored, allowing only coarse adjustments. Furthermore, this method only regulates the hydraulic pressure in the secondary network and cannot meet the varying heating temperature demands of users, potentially leading to heat waste. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to provide a smart heating temperature control system. This system addresses the limitations of existing heating management systems in precisely regulating indoor temperatures and in coordinating the primary and secondary heating networks to meet resident needs. The smart heating temperature control system is implemented through the following technical solution:

The primary side valve control module is electrically connected to the first control valve and the seventh control valve.

[0019] Furthermore, a first pressure sensor is installed on the primary side return water pipe. The first pressure sensor is electrically connected to the primary side pressure judgment module through the primary side pressure acquisition module. The primary side pressure judgment module is electrically connected to the primary side main control module.

[0020] Furthermore, it also includes a secondary side makeup water heat exchanger, wherein the first interface of the secondary side makeup water heat exchanger is connected to the primary side bypass pipe through the secondary side makeup water heat exchange supply pipe, the second interface is connected to the primary side return water pipe through the secondary side makeup water heat exchange return water pipe, the third interface is connected to the secondary side supply water pipe through the secondary side makeup water pipe, and the fourth interface is connected to the outlet end of the secondary side makeup water pump.

[0026] The present invention also includes a primary side water supply pipeline and a secondary side water supply pipeline. When either the primary side pipeline or the secondary side pipeline is under-pressured, water supply can be carried out separately. During the heating process, when the secondary side pipeline is under-pressured, the control system can directly adjust the heat medium on the primary side to heat the water supplied to the secondary side, thus avoiding large temperature fluctuations in the secondary side pipeline during water supply, which could affect the end user.

The household end is connected to a manifold via a household return water pipe 122, and the manifold is connected to the secondary side return water pipe 123. One end of the secondary side bypass pipe 125 is connected to the building water inlet pipe. A fourth temperature sensor 121 is installed at the household end.

[0042] It also includes a secondary side water supply pipeline, which includes a secondary side water supply heat exchanger 109. The first port of the secondary side water supply heat exchanger 109 is connected to the primary side bypass pipe 128 via a secondary side water supply heat exchanger supply pipe 108.

An eighth control valve 130 is installed on the secondary side water supply heat exchanger return pipe 106. The connection point between the secondary side water supply heat exchanger supply pipe 108 and the primary side bypass pipe 128 is located between the eighth control valve 130 and the primary side supply pipe 102.

[0043] The third port of the secondary side makeup water heat exchanger 109 is connected to the secondary side water supply pipe 116 through the secondary side makeup water pipe 111, and a third control valve 112 is installed on the secondary side makeup water pipe 111. The fourth port of the secondary side makeup water heat exchanger 109 is fixedly connected to the outlet end of the secondary side makeup water pump 110.

[0044] It also includes a primary side water supply pipeline, which includes a primary side water supply pump 132. The output end of the primary side water supply pump 132 is connected to the ninth control valve 134 and the primary side return water pipe 131 in sequence through the primary side water supply pipe 133.

[0045] The control system includes a central control module 218, which is electrically connected to an outdoor temperature acquisition module 219, a primary side control system, and a secondary side control system.

[0046] The primary side control system includes a primary side main control module 222 that is electrically connected to the primary side water supply control module 206, the primary side pressure judgment module 207, the primary side temperature judgment module 221, the primary side circulation pump control module 202, and the primary side valve control module 203, respectively. The primary side main control module 222 is electrically connected to the central control module 218.

[0047] The primary water replenishment control module 206 is electrically connected to the primary side water replenishment pump control module 205 and the primary side water replenishment valve control module 204, respectively.

[0048] The primary side pressure judgment module 207 is electrically connected to the primary side pressure acquisition module 208, and the primary side pressure acquisition module 208 is electrically connected to the first pressure sensor. The primary side pressure acquisition module 208 acquires the water pressure of the primary side pipeline, sends it to the primary side pressure judgment module 207 for comparison with the preset pressure, and sends the comparison result to the primary side main control module 222.

[0049] The primary side temperature judgment module 221 is electrically connected to the primary side temperature acquisition module 220. The primary side temperature acquisition module 220 is electrically connected to the first temperature sensor 104 and the sixth temperature sensor 127 respectively. The first temperature sensor 104 and the sixth temperature sensor 127 respectively acquire the water temperature of the primary side water supply pipe 102 and the primary side water return pipe 131, send them to the primary side temperature judgment module 221, and compare them with the preset primary side water supply temperature and primary side water return temperature respectively. The comparison result is then sent to the primary side main control module 222.

[0050] The primary circulation pump control module 202 is electrically connected to the primary circulation pump 103 and controls the start-up, shutdown and operating frequency of the primary circulation pump 103.

[0051] The primary side valve control module 203 is electrically connected to the first control valve 105 and the seventh control valve 129 respectively, controlling the opening and closing degree of each valve body, thereby controlling the flow rate in the corresponding pipeline.

[0052] The primary water supply valve control module 204 is electrically connected to the ninth control valve 134 to control its opening and closing.

[0053] The primary side water supply pump control module 205 is electrically connected to the primary side water supply pump 132 to control its start-up and shutdown.

[0054] The secondary side sub-control system includes a secondary side pressure judgment module 209, a secondary side water replenishment control module 213, a secondary side valve control module 214, a secondary side temperature judgment module 216, and a secondary side circulating pump control module, all of which are electrically connected to the secondary side main control module 215. The secondary side main control module 215 is electrically connected to the central control module 218.

[0055] The secondary side pressure judgment module 209 is electrically connected to the secondary side pressure acquisition module 210, and the secondary side pressure acquisition module 210 is electrically connected to the second pressure sensor. The secondary side pressure acquisition module 210 acquires the water pressure of the secondary side pipeline and sends it to the secondary side pressure judgment module 209. The secondary side pressure judgment module 209 compares the acquired water pressure with the preset water pressure and sends the comparison result to the secondary side main control module 215.

[0056] The secondary water supply control module 213 is electrically connected to the secondary water supply valve control module 211 and the secondary water supply pump control module 212. The secondary water supply valve control module 211 is electrically connected to the second control valve 107, the third control valve 112, and the eighth control valve 130, respectively, and controls the opening and closing of each valve; the secondary water supply pump control module 212 is electrically connected to the secondary water supply pump 110 and controls its start-up and shutdown.

[0057] The secondary side valve control module 214 is electrically connected to the fourth control valve 115, the fifth control valve 117, the tenth control valve 119, and the sixth control valve 126 respectively, and controls the opening and closing degree of each valve.

[0058] The secondary temperature judgment module 216 is electrically connected to the secondary temperature acquisition module 217. The secondary temperature acquisition module 217 is electrically connected to the second temperature sensor 114, the third temperature sensor 118, the fourth temperature sensor 121, and the fifth temperature sensor 124, respectively. The second temperature sensor 114, the third temperature sensor 118, the fourth temperature sensor 121, and the fifth temperature sensor 124 acquire the temperature at their respective locations and send it to the secondary temperature acquisition module 217. The secondary temperature acquisition module 217 sends this temperature data to the secondary temperature judgment module 216, where it compares the data with the corresponding preset temperature. Then, the secondary temperature judgment module 216 sends the comparison result to the secondary main control module 215.

[0059] The secondary circulation pump control module is electrically connected to the secondary circulation pump 113, and controls the start and stop of the secondary circulation pump 113 according to the instructions of the secondary main control module 215.

[0060] Before formal heating begins, the central control module 218 first sends a pressure test command to the primary side main control module 22 and the secondary side main control module 215 to perform pressure tests on the primary and secondary piping. For the primary side piping, the primary side circulation pump 103 and the first control valve 105 are started first, while the seventh control valve 129 is closed for pressure testing; then, the seventh control valve 129 is opened for further pressure testing. The first pressure sensor detects the actual pressure in the primary side piping and sends it to the primary side pressure judgment module 207 via the primary side pressure acquisition module 208. The pressure is compared with the preset pressure to determine if there is a pressure deficiency.

[0061] The primary side pressure judgment module 207 sends the comparison result to the central control module 218 through the primary side main control module 222. If the result obtained by the primary side main control module 222 is underpressure, the central control module 218 generates a water replenishment command and sends it to the primary side main control module 222. Then, the primary side main control module 222 generates a water replenishment signal and sends it to the primary water replenishment control module 206. Then, the primary water replenishment control module 206 opens the ninth control valve 134 and the primary side water replenishment pump 132 through the primary side water replenishment valve control module 204 and the primary side water replenishment pump control module 205 to replenish water until the measured pressure equals the preset pressure. The primary side main control module 222 then controls the ninth control valve 134 and the primary side water replenishment pump 132 to close through the primary water replenishment control module 206.

[0062] When the secondary pipeline is pressure tested, the secondary side circulation pump 113, the fourth control valve 115, the sixth control valve 126, and the fifth control valve 117 are started first, and the tenth control valve 119 is closed. Then, the tenth control valve 119 is opened and the sixth control valve 126 is closed. The second pressure sensor collects the measured pressure in the secondary side pipeline and sends it to the secondary side pressure judgment module 209 via the secondary side pressure acquisition module 210. It is compared with the corresponding preset pressure to determine whether there is underpressure. The comparison result is sent to the central control module 218 via the secondary side main control module 215. If the result obtained by the secondary side main control module 215 is underpressure, the central control module 218 generates a water replenishment command. The command is sent to the secondary-side main control module 215, which generates a no-water-replenishment signal and sends it to the secondary-side water-replenishment control module 213. The secondary-side water-replenishment control module 213 opens the third control valve 112 through the secondary-side water-replenishment valve control module 211 and starts the secondary-side water-replenishment pump 110 through the secondary-side water-replenishment pump control module 212 to replenish water until the measured value of the second pressure sensor matches the preset value. The central control module 218 generates a command to end water replenishment and sends it to the secondary-side main control module 215. The secondary-side main control module 215 closes the third control valve 112 and the secondary-side water-replenishment pump control module 212 through the secondary-side water-replenishment control module 213.

[0063] The temperature control process is as follows: First, the central control module 218 obtains the instruction to start heating and the outdoor temperature, and calculates the temperature thresholds at various points in the primary and secondary pipes based on the outdoor temperature. Then, the central control module 218 sends the corresponding temperature information and heating instruction to the primary main control module 222 and the secondary main control module 215, where the outdoor temperature is weather forecast data.

[0064] According to the instructions, the primary side main control module 222 starts the primary side circulation pump 103 through the primary side circulation pump control module 202 and starts the first control valve 105 and the eighth control valve 130 through the primary side valve control module 203.

[0065] The secondary-side main control module 215 starts the secondary-side circulation pump 113 through the secondary-side circulation pump control module, and starts the fourth control valve 115, the fifth control valve 117, the tenth control valve 119, and the sixth control valve 126 through the secondary-side valve control module 214. The data T2, T3, T4, and T5 detected by the second temperature sensor 114, the third temperature sensor 118, the fourth temperature sensor 121, and the fifth temperature sensor 124 are acquired in real time by the secondary-side temperature acquisition module 217 and sent to the secondary-side temperature judgment module 216 for comparison with the preset temperature ranges T21, T31, T41, and T51, and the results are sent to the secondary-side main control module 215; if the measured temperature is within the predetermined range, the current operation is maintained. If the measured temperature T4 is lower than the lower limit of T41, the secondary side main control module 215 increases the opening of the tenth control valve 119 and decreases the opening of the sixth control valve 126 through the secondary side valve control module 214 to make the measured temperature T4 meet the requirements. If the measured temperature T4 is higher than the upper limit of T41, the opening of the tenth control valve 119 is decreased and the opening of the sixth control valve 126 is increased to make the measured temperature T4 meet the requirements. If T4 meets the requirements and T5 is higher than the upper limit of T51, the secondary side main control module 215 reduces the speed of the secondary side circulation pump 113 through the secondary side circulation pump control module.

[0066] If both T2 and T3 are below the corresponding lower limits of T21 and T31, the secondary-side main control module 215 sends this information to the central control module 218. The central control module 218 generates a control command based on this information and sends it to the primary-side main control module 222. The primary-side main control module 222 then controls the amount of heat medium entering the heat exchanger through the primary-side pipeline to increase. That is, after receiving the control command, the primary-side main control module 222 reduces the opening of the eighth control valve 130 through the primary-side valve control module 203, allowing more heat medium to enter the heat exchanger.

[0067] During operation, the data T1 and T6 detected by the first temperature sensor 104 and the sixth temperature sensor 127 are collected in real time by the primary side temperature acquisition module 220 and sent to the primary side temperature judgment module 221. The primary side temperature judgment module 221 compares the measured temperature data with the corresponding preset temperature thresholds T11 and T61, and sends the comparison result to the primary side main control module 222. The primary side main control module 222 adjusts the seventh control valve 129 and the primary side circulation pump 103 according to the temperature comparison result. If T6 is higher than the upper limit of T61, the primary side main control module 222 increases the opening of the eighth control valve 130 through the primary side valve control module 203. If T6 is still higher than the upper limit of T61, the primary side main control module 222 decreases the speed of the primary side circulation pump 103 through the primary side circulation pump control module 202. If T1 meets the requirements and T6 is lower than the lower limit of T61, the primary side main control module 222 decreases the opening of the eighth control valve 130 through the primary side valve control module 203. If T1 is lower than the lower limit of T11, then check heat source 101.

[0068] During the heating process, the first pressure sensor detects the pressure of the primary side pipeline in real time and sends it to the primary side pressure judgment module 207 via the primary side pressure acquisition module 208. The primary side pressure judgment module 207 compares the pressure value with the preset pressure value and sends the comparison result to the primary side main control module 222. If the primary side main control module 222 receives a pressure undervoltage signal, it will replenish water. The water replenishment process is the same as that during the pressure test and will not be described again.

[0069] During the heating process, the second pressure sensor detects the pressure of the secondary side pipeline in real time and sends it to the secondary side pressure judgment module 209 via the secondary side pressure acquisition module 210. The secondary side pressure judgment module 209 compares the pressure data with the preset pressure data and sends the comparison result to the secondary side main control module 215. The secondary side main control module 215 then sends the result to the central control module 218. If the secondary side main control module 215 receives a result indicating underpressure, the central control module 218 generates a water replenishment command and sends it to the secondary side main control module 215. The secondary side main control module 215 generates water replenishment information and sends it to the secondary side water replenishment control module 213. The secondary side water replenishment control module 213 controls relevant components to replenish water based on the information. Specifically, after receiving the water replenishment information, the secondary side water replenishment control module 213 opens the second control valve 107, the third control valve 112, and the first control valve 105 via the secondary side water replenishment valve control module 211, and starts the secondary side water replenishment pump 110 via the secondary side water replenishment pump control module 212. After the cold water undergoes heat exchange in the secondary side water supply heat exchanger 109, it enters the secondary side water supply pipe 116. During the water supply process, the second pressure sensor detects the pressure value in real time until it is equal to the preset value. The central control module 218 sends a stop water supply command to the secondary side water supply control module 213 through the secondary side main control module 215. The secondary side water supply control module 213 closes the second control valve 107, the third control valve 112, the first control valve 105, and the secondary side water supply pump 110 through the secondary side water supply valve control module 211 and the secondary side water supply pump control module 212.
