Description

Technical Field

[0001] The present invention belongs to the field of heating, ventilation and air conditioning, and in particular relates to an energy-saving multi-stage temperature regulating device and method for an indirect heat exchange system. Background Art

[0002] With the development of society and the continuous advancement of science and technology, indirect heat exchange systems are increasingly used in refrigeration, heating, air conditioning and many other industrial fields, becoming an indispensable part of modern life. As an efficient heat transfer method, the core of the indirect heat exchange system is to use an intermediate medium (such as water, air or a specific refrigerant) to effectively transfer heat between two non-contacting fluid systems. This mechanism gives the indirect heat exchange system many advantages such as simple structure, safe and reliable operation, and convenient maintenance. Especially when it is necessary to strictly isolate different fluids or handle corrosive and toxic fluids, its advantages are particularly prominent.

[0003] Although traditional indirect heat exchange systems have shown strong practicality in many applications, they face considerable challenges in temperature control. In the past, the temperature regulation of the system mainly relied on a single flow control valve, which controlled the fluid flow through the heat exchanger by manually or automatically adjusting the opening degree of the valve, thereby achieving indirect temperature regulation. However, in the face of complex and changeable climatic conditions, large fluctuations in indoor and outdoor temperature differences, and specific needs in different seasons, this single control method seems to be inadequate.

[0004] Extreme weather phenomena caused by climate change are becoming more frequent, and the temperature difference between indoors and outdoors is becoming more unpredictable, which brings great uncertainty to the temperature control of indirect heat exchange systems. Even small fluctuations in system temperature may have a significant impact on the comfort of the indoor environment, and also affect the operating efficiency and energy consumption level of the equipment. Inaccurate temperature control will not only reduce user satisfaction, but also lead to serious waste of energy, thereby increasing the operating cost and maintenance burden of the system.

[0005] More importantly, as the requirements for temperature control accuracy in the construction and industrial fields are increasing, the traditional single valve control method can no longer meet the complex and changing application requirements. Especially in high-end application scenarios such as large commercial buildings, data centers, and precision manufacturing plants, unprecedented high requirements are placed on the accuracy and stability of temperature control. Therefore, exploring and developing more advanced and intelligent temperature control technologies has become an inevitable trend in the future development of indirect heat exchange systems.

[0050] like Figure 1 As shown, another embodiment of the present invention provides an energy-saving multi-stage temperature regulating device for an indirect heat exchange system, comprising: like Figure 1 As shown, the temperature regulating valve group 1, multiple regulating valves are connected in series, and each valve can be set to a different opening; the valve includes an electric valve and a connecting pipe. The sensor module 3 has an infrared temperature sensor, a turbine flowmeter, and a differential pressure sensor. The temperature controller includes a microprocessor, an input / output interface, a display panel, and a user interface. The intelligent regulating module has a microprocessor, an algorithm library, and a communication interface (such as a serial communication interface). The regulating valve motor controls the regulating valve opening by executing the instructions of the intelligent regulating module.

[0051] The temperature regulating valve group 1 includes multiple regulating valves. Before installation, the regulating range of each regulating valve is accurately set according to the overall design requirements of the system and the expected operating temperature range. These regulating valves are equipped with electric valves and connecting pipes. The action of the electric valve directly affects the fluid flow and temperature regulation effect. Under heating conditions, if the indoor temperature needs to be increased, the corresponding regulating valve can increase the opening to increase the heat medium flow, thereby increasing the heat exchange; conversely, when cooling, the opening is reduced to control the refrigerant flow. The sensor module 3 integrates a variety of key sensors. Among them, the infrared temperature sensor is used for non-contact measurement of fluid or ambient temperature. Its advantages are fast response speed and high measurement accuracy, and it can quickly capture temperature changes. As a flow sensor, the turbine flowmeter can accurately measure the fluid flow. Its working principle is based on the proportional relationship between the force of the fluid on the turbine blades and the flow rate, providing flow data support for system control. The differential pressure sensor monitors the water flow pressure difference in real time. Once the pressure difference fluctuates abnormally, it may indicate pipeline blockage or other hydraulic problems, which is crucial for timely adjustment of the valve opening and reduction of hydraulic losses. These sensors are distributed in the water supply pipeline of the thermal power station, continuously collecting data and transmitting it to the subsequent control unit. The core component of the temperature controller is a microprocessor, equipped with an input / output interface, a display panel and a user interface. Its main function is to compare the deviation between the set water temperature and the actual water temperature in real time. During operation, the temperature feedback signal from the sensor is continuously received, and after internal program calculation and processing, a specific algorithm is used to calculate the opening value of the regulating valve that meets the temperature regulation requirements based on the difference between the set temperature and the actual water temperature, and the signal is transmitted to the intelligent regulation module. The display panel can intuitively display information such as the current temperature setting value, the actual measurement value and the system operation status, which is convenient for users to view at any time; the user interface provides users with an operation entry, such as temperature setting adjustment. The intelligent regulation module has a built-in microprocessor and a rich algorithm library, and is equipped with a communication interface (such as a serial communication interface). After receiving the signal from the temperature controller, it combines the preset control strategy with the multi-level temperature control algorithm in the algorithm library for in-depth analysis and processing. The algorithm fully considers the influence of multiple factors such as indoor and outdoor temperature difference, system load changes, and heat exchanger efficiency, and accurately generates control instructions to send to the regulating valve motor. At the same time, the intelligent adjustment module will dynamically adjust the valve opening according to the pressure difference changes fed back by the pressure difference sensor, effectively avoiding energy waste and equipment loss caused by hydraulic instability. When abnormal conditions such as valve failure or sensor failure are detected during system operation, the intelligent adjustment module can quickly switch to safe mode to ensure the overall stability of the system and prevent temperature runaway or other safety hazards. As an actuator, the regulating valve motor drives the regulating valve in strict accordance with the instructions of the intelligent adjustment module, accurately controls the valve opening, and achieves a multi-level temperature adjustment effect. The regulating valve group sets the multi-level opening according to a certain gradient based on the system characteristics, thereby achieving fine-grained temperature control.In the temperature fine-tuning stage, precise temperature control is achieved by adjusting the opening of specific regulating valves in small increments; when there is a large temperature deviation, multiple regulating valves work together to quickly return the temperature to the set range. When the deviation between the set temperature and the actual temperature is within a reasonable range, the system maintains the current opening and operates stably, reducing unnecessary valve movements and energy consumption.

[0052] By working together, these components enable efficient temperature control, ensuring the system operates stably within the set temperature range while reducing energy consumption and avoiding unnecessary safety risks.

[0053] Workflow: According to the design requirements of the system and the expected operating temperature, set the adjustment range of each regulating valve. Connect the temperature controller, intelligent adjustment module, sensor and actuator to ensure smooth data transmission and control signal. When working, the temperature controller monitors the deviation between the set water temperature and the actual water temperature in real time. According to the deviation between the set temperature and the actual water temperature, the temperature controller calculates the opening of the required regulating valve through an algorithm. The intelligent adjustment module receives the signal of the temperature controller, adjusts the output of the actuator according to the preset control strategy and algorithm, and controls the opening of the regulating valve. The regulating valve group sets multiple levels of opening according to a certain gradient to achieve fine-grained temperature regulation. When the deviation between the set temperature and the actual temperature is within a certain range, the system keeps the current opening unchanged. When the deviation exceeds the preset range, the system automatically adjusts the opening of the corresponding regulating valve until the deviation returns to a reasonable range. The sensor detects the water flow pressure difference in real time, and the intelligent adjustment module adjusts the valve opening according to the pressure difference change to reduce unnecessary hydraulic loss. By monitoring the sensor data, once a valve failure or sensor failure is detected, the intelligent adjustment module will automatically switch to safe mode to maintain the stability of the system.

[0054] The present invention also provides a method for regulating a multi-stage temperature regulating valve group, which is characterized by comprising: The sensor module is used to monitor the fluid data in the system in real time; the sensor module can monitor the fluid data in the system in real time to ensure accurate grasp of the system status. This real-time monitoring helps to detect any abnormal situation in time so that corresponding measures can be taken.

[0055] The intelligent control module uses a multi-stage temperature control algorithm to control the regulating valve motor to dynamically adjust the opening degree of each valve based on the fluid data, the preset temperature target and real-time temperature feedback; The intelligent control module uses a multi-level temperature control algorithm to dynamically adjust the opening degree of each valve based on real-time fluid data and preset temperature targets. This precise control can achieve rapid response and stable regulation of temperature, improving the overall performance of the system.

[0056] The multi-level temperature control algorithm can flexibly adjust the valve opening degree according to different temperature requirements to achieve fine temperature regulation. This helps to reduce energy waste and improve energy efficiency.

[0057] Implement regular optimization procedures to continuously adjust control parameters based on historical data and learning algorithms.

[0058] Implementing regular optimization procedures and continuously adjusting control parameters using historical data and learning algorithms can gradually adapt and optimize the system to its operating environment. This adaptive capability helps improve the reliability and stability of the system.

[0059] Also includes: When a valve failure or sensor failure is detected, the intelligent control module automatically switches to safe mode to maintain system stability. This fault detection and response mechanism helps ensure that the system can take prompt action when a fault occurs to prevent the fault from expanding or causing more serious consequences.
