Abstract
Description
Technical Field
[0001] This utility model relates to the field of heating, ventilation and air conditioning technology, and in particular to a heating pipe network control system. Background Technology
[0002] The Heating, Ventilation, and Air Conditioning (HVAC) control system is an automated system integrated into intelligent buildings. It primarily regulates the operation of heating, ventilation, and air conditioning equipment within the building. By monitoring parameters such as temperature, humidity, and air quality, it ensures a comfortable indoor environment and improves energy efficiency. Heating systems mainly include hot water heating and steam heating, with hot water heating being more common in buildings. Hot water heating utilizes the circulation of hot water with a secondary heat exchanger to maintain indoor temperature. The basic components of this system include: a boiler, a circulating pump, a secondary heat exchanger, a piping system, and indoor terminals. Ventilation refers to the process of introducing fresh air into an indoor space and removing stale air. The main purpose of ventilation is to ensure indoor air quality; proper ventilation can also lower the indoor temperature. Ventilation includes both natural ventilation and mechanical (forced) ventilation. An air conditioning system is a combination of components that, under human control, regulate the air inside a building to achieve the required conditions.
[0003] Traditional heating pipe systems have the following problems:
[0004] 1. Uneven heat distribution, especially in branch pipes of different diameters, with large temperature fluctuations (above ±3℃), which cannot meet the needs of precision laboratories and other scenarios;
[0005] 2. Pipeline pressure is affected by heat source fluctuations and ambient temperature, and is prone to overpressure leading to pipeline rupture;
[0006] 3. Relying on manual adjustment of valve opening results in delayed response and low control accuracy;
[0007] In existing technologies, although some systems use electric regulating valves, they lack multi-valve collaborative control, intelligent pressure relief protection, and remote monitoring functions, making it difficult to achieve efficient and stable pipeline regulation. Therefore, a heating pipeline control system is designed to solve the above problems. Utility Model Content
[0008] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a heating pipe network control system.
[0009] The technical problem to be solved by this utility model is to provide a heating pipe network control system to solve the problems of existing heating pipe network control systems.
[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0011] A heating network control system includes a plate heat exchanger and a control cabinet, wherein the control cabinet includes an intelligent temperature control module and an automatic pressure relief module;
[0012] The intelligent temperature control module includes a first regulating valve, a second regulating valve, and a first temperature sensor. The first regulating valve is installed on the primary heating pipe; the second regulating valve is installed on the secondary heating pipe; and the first temperature sensor is installed on the primary return heating pipe. The primary heating pipe is connected to the primary inlet of the plate heat exchanger, and the primary outlet of the plate heat exchanger is connected to the primary return heating pipe. The secondary outlet of the plate heat exchanger is connected to the secondary heating pipe.
[0013] The automatic pressure relief module includes an electric contact pressure gauge and a pressure relief valve. The electric contact pressure gauge is installed on the secondary heating pipe, and the pressure relief valve is installed through the secondary heating pipe.
[0014] Preferably, the first regulating valve, the second regulating valve, and the first temperature sensor are electrically connected to the control cabinet.
[0015] Preferably, the pressure gauge and pressure relief valve are electrically connected to the control cabinet.
[0016] Preferably, the control cabinet further includes a remote monitoring module, which is electrically connected to the remote control room.
[0017] Preferably, the remote monitoring module integrates 4G communication functionality, supporting data uploading and command issuance.
[0018] Preferably, the control cabinet is equipped with a temperature control instrument, which has a built-in PID algorithm to compare the return water temperature (PV) with the set value temperature (SV) in real time to achieve closed-loop control.
[0019] Preferably, a second temperature sensor is also provided on the heating secondary pipe.
[0020] Preferably, the second temperature sensor is located at the point where the diameter of the secondary heating pipe changes.
[0021] Preferably, the electric contact pressure gauge monitors the pressure of the secondary pipeline in real time, with an upper limit of 0.65 MPa and a lower limit of 0.63 MPa.
[0022] Preferably, a heating supply system and a heating return system are respectively connected to the heating primary pipe and the return primary pipe.
[0023] Compared with the prior art, this utility model has at least the following beneficial effects:
[0024] In the above scheme, a first regulating valve, a second regulating valve, and a first temperature sensor are set up. Based on the temperature sensed by the first temperature sensor, a signal is sent to the first temperature control instrument to detect the return water temperature on the first heating pipe. When the return water temperature deviates, a control signal is output through PID calculation to drive the opening degree of the first regulating valve and the second regulating valve to achieve the effect of target temperature regulation, prevent excessive temperature fluctuations, and ensure normal heating.
[0025] In the above scheme, the first regulating valve is installed on the primary heating pipe, and the basic opening is preset by the heating company. The second valve is installed on the secondary heating pipe, and the opening of the second valve can be adjusted according to the needs to dynamically regulate the branch temperature on the secondary heating pipe, so as to avoid uneven heat distribution.
[0026] In the above scheme, an electric contact pressure gauge and a pressure relief valve are installed. The electric contact pressure gauge monitors the pressure in the secondary pipe network in real time. When the electric contact pressure gauge senses that the pressure in the secondary heating pipe is too high, it sends a signal to the control cabinet. The control cabinet then controls the pressure relief valve to open and release the pressure, preventing the pipe from rupturing due to excessive pressure in the secondary heating pipe and ensuring the service life of the heating network pipe.
[0027] In the above scheme, a remote control room is set up, which can realize remote control and support the issuance of manual intervention or algorithm optimization instructions.
[0028] By incorporating a second temperature sensor, when the temperature of the secondary heating pipe deviates from the set temperature due to a change in diameter, the second temperature sensor detects the temperature and sends a signal to the control box. The control box then controls the opening degree of the second regulating valve, thereby regulating the temperature inside the secondary heating pipe, preventing excessive temperature fluctuations, and ensuring normal heating.
