[0014] The technical solution provided in this application document has the following beneficial effects:

[0015] This invention provides an intelligent cold and heat source inlet control device, including a heat exchanger, a control device, a heating end pipeline, a user end pipeline, and a first temperature sensor. The heating end pipeline and the user end pipeline are respectively connected to the heat exchanger, and heat or cold energy in the heating end pipeline is exchanged with energy in the user end pipeline within the heat exchanger. The user end pipeline is laid in each room, and each room is equipped with a first temperature sensor for detecting the room temperature. The first temperature sensor is electrically connected to the control device. The heating end pipeline is equipped with an automatic regulating valve, which is also electrically connected to the control device. The control device controls the automatic regulating valve based on the temperature detected by the first temperature sensor. The opening size is determined by the following: Specifically, the staff sets the indoor temperature to a first preset value for a first time period and a second preset value for a second time period on the control device. During the first time period, the temperature detected by the first temperature sensor in each room is transmitted to the control device. The control device averages the received data and compares it with the first preset value. If the average value is higher than the first preset value, the control device controls the opening of the automatic regulating valve to decrease the liquid flow rate and reduce the heat exchange, thereby lowering the average temperature. If the average value is lower than the first preset value, the control device controls the opening of the automatic regulating valve to increase the liquid flow rate and increase the heat exchange, thereby raising the average temperature.

[0016] This setup, with the heating end pipeline and the user end pipeline separated by a heat exchanger, prevents water from entering the user end pipeline, ensuring the water balance of the external network. Furthermore, it allows for precise control of the average room temperature across multiple rooms, based on the building's function and usage time, thus minimizing heating and cooling energy consumption and saving energy. In addition, the control equipment can be modularized; it can be installed at the building entrance to control the temperature of the entire building, on the main pipelines of each floor to control the average indoor temperature of a single floor, or in each room for precise temperature control.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This specific embodiment provides an intelligent cold and heat source inlet control device, which solves the technical problems of external network water imbalance and inability to adjust temperature in real time in the prior art.

[0023] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the following embodiments are not limited to those necessary for the solution of the utility model as described in the claims.

[0024] Reference Figures 1-2This utility model provides an intelligent cold and heat source inlet control device, including a heat exchanger 1, a control device 2, a heating end pipeline 3, a user end pipeline 4, and a first temperature sensor 6. The heating end pipeline 3 and the user end pipeline 4 are respectively connected to the heat exchanger 1. Heat or cold energy in the heating end pipeline 3 is exchanged with energy in the user end pipeline 4 within the heat exchanger 1, transferring energy from the heating end pipeline 3 to the user end pipeline 4. Since the heating end pipeline 3 and the user end pipeline 4 are separated by the heat exchanger 1, the supply... Water from the heating end pipe 3 will not enter the user end pipe 4, ensuring the water balance of the external network. The user end pipe 4 is laid in each room, and each room is equipped with a first temperature sensor 6. The first temperature sensor 6 is used to detect the temperature in the room and is electrically connected to the control device 2. The heating end pipe 3 is equipped with an automatic regulating valve 321, which is electrically connected to the control device 2. The control device 2 controls the opening size of the automatic regulating valve 321 according to the temperature detected by the first temperature sensor 6. Specifically, the staff sets the indoor temperature to a first preset value for a first time period and a second preset value for a second time period on the control device 2. During the first time period, the temperature detected by the first temperature sensor 6 in each room is transmitted to the control device 2. The control device 2 averages the received data and compares it with the first preset value. If the average value is higher than the first preset value, the control device 2 controls the opening of the automatic regulating valve 321 to decrease the liquid flow rate and reduce the heat exchange, thereby lowering the average temperature. If the average value is lower than the first preset value, the control device 2 controls the opening of the automatic regulating valve 321 to increase the liquid flow rate and increase the heat exchange, thereby raising the average temperature.

[0025] With this setup, since the heating end pipe 3 and the user end pipe 4 are separated by the heat exchanger 1, the water source in the heating end pipe 3 will not enter the user end pipe 4, ensuring the water balance of the external network. At the same time, it can also accurately control the average room temperature in multiple rooms according to the different temperature requirements of the building's use function and usage time, thereby minimizing heating and cooling energy consumption and saving energy. In addition, the control equipment can be modularized and can be installed at the entrance of the entire building to control the temperature of the entire building, or installed on the main pipes on each floor of the building to control the average indoor temperature in the rooms of a single floor, or installed in each room to achieve precise temperature control of a single room.

[0026] In addition, the control device 2 includes a control distribution cabinet 21 and a central control center 22. The central control center 22 is electrically connected to the control distribution cabinet 21, and the control distribution cabinet 21 is electrically connected to the automatic regulating valve 321 and the first temperature sensor 6, which facilitates centralized control.

[0027] Further optimization of the scheme also includes a water replenishment component 5, which includes a water replenishment pump 51 and a pressure tank 52 connected in sequence. The water replenishment pump 51 and the pressure tank 52 are electrically connected to the control device. The pressure tank 52 is connected to the user-end pipeline 4. The water replenishment pump 51 is used to connect to the water source to replenish water into the pressure tank 52 to ensure the water pressure in the user-end pipeline 4.

[0028] To further optimize the solution, for convenient water replenishment, the inlet of the water replenishment pump 51 is connected to the softened water system, thus directly replenishing the water in the softened water system to the pressure tank 52. Alternatively, the water replenishment pump 51 can be connected to the heating end pipeline 3, and an electric two-way valve is installed between the water replenishment pump 51 and the heating end pipeline 3. The electric two-way valve is electrically connected to the control device 2. Both the water replenishment pump 51 and the pressure tank 52 are electrically connected to the control device, so that the control device can receive the pressure signal from the pressure tank 52 and simultaneously control the opening and closing of the water replenishment pump 51.

[0029] The scheme is further optimized. The heating end pipeline 3 includes a first inlet pipe 31 and a first outlet pipe 32 connected to the heat exchanger 1. The first inlet pipe 31 is sequentially equipped with a first gate valve 311, a first pressure sensor 312, and a third temperature sensor 313 to facilitate the detection of pressure and temperature in the first inlet pipe 31. The first outlet pipe 32 is sequentially equipped with a second pressure sensor 323, a fourth temperature sensor 322, a self-regulating differential pressure control valve 324, and a second gate valve 325 to facilitate the detection of pressure and temperature in the first outlet pipe 32. An automatic regulating valve 321 is installed on the first outlet pipe 32 so as not to affect the energy exchange of the heat exchanger. The first pressure sensor 312, the third temperature sensor 313, the second pressure sensor 323, and the fourth temperature sensor 322 are electrically connected to the control device 2 to facilitate the control device 2 to judge the efficiency of energy exchange.

[0030] The scheme is further optimized by connecting the first inlet pipe 31 and the first outlet pipe 32 through a third pipe 33, and a fifth gate valve 331 is installed on the third pipe 33. This facilitates the adjustment of the pressure between the first inlet pipe 31 and the first outlet pipe 32, ensuring that the liquid can move normally.

[0031] Further optimizing the design, the user-end pipeline 4 includes a second inlet pipe 41 and a second outlet pipe 42 connected to the other side of the heat exchanger 1. The outlet end of the second inlet pipe 41 is connected to the indoor pipeline, and the inlet end of the second outlet pipe 42 is connected to the indoor pipeline. The second inlet pipe 41 is sequentially equipped with a user circulating water pump 411, a third pressure sensor 412, a fifth temperature sensor 413, and a third gate valve 414. The user circulating pump pumps water into the indoor pipeline, and the third pressure sensor 412 and the fifth temperature sensor 413 detect the water level inlet pipe. The pressure and temperature inside the water pipe 41; the second water outlet pipe 42 is sequentially equipped with a fourth gate valve 421, a fourth pressure sensor, and a sixth temperature sensor 423. The fourth pressure sensor 422 and the sixth temperature sensor 423 detect the pressure and temperature inside the second water outlet pipe 42. The user circulating water pump 411, the third pressure sensor 412, the fifth temperature sensor 413, and the sixth temperature sensor 423 are electrically connected to the control device 2, which facilitates the adjustment of the pressure between the first water inlet pipe 31 and the first water outlet pipe 32, ensuring that the liquid can move normally.

[0032] To further optimize the solution, in order to facilitate the measurement of the flow rate on the second outlet pipe 42, a flow meter 424 is installed on the second outlet pipe 42 of the user-end pipe 4. The flow meter 424 is electrically connected to the control device 2, so that the control device can collect the data collected by the flow meter 424.

[0033] Further optimization of the scheme also includes a seventh temperature sensor 7 electrically connected to the control device 2. The seventh temperature sensor 7 is located outdoors to facilitate knowing the outdoor temperature and to facilitate the overall adjustment of the control device.

[0034] To further optimize the solution and ensure continuous hot and cold circulation, two user circulating water pumps 411 are installed. The user circulating water pumps 411 are connected in parallel to the second inlet pipe 41. In addition, the user circulating water pumps 411 are not limited to two; three can also be installed in parallel. This ensures the fluidity of the liquid even if one of them fails.
