[0002] A scroll compressor is a positive displacement compressor whose compression components primarily consist of an orbiting scroll and a fixed scroll. During operation, the orbiting scroll is driven by an eccentric shaft and, constrained by an anti-rotation mechanism, rotates in a plane with a very small radius around the center of the fixed scroll's base circle. The relative orbital motion of the orbiting and fixed scrolls creates a continuous change in the enclosed volume, enabling the intake, compression, and discharge of gas.

[0003] During the suction, compression, and exhaust processes, the fixed scroll is fixed to the frame, while the orbiting scroll is driven to rotate by the eccentric shaft. Gas is drawn into the periphery of the fixed scroll through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed within the crescent-shaped compression chamber formed by the meshing of the orbiting and fixed scrolls, and finally discharged continuously through the axial hole in the center of the fixed scroll.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 2 As shown:

[0022] Embodiment 1: The present invention provides an air-conditioning scroll compressor high-efficiency energy-saving device, comprising:

[0023] Scroll compressor 1, air intake pipe 2, exhaust pipe 3, pressure sensor 4, temperature sensor 5 and an intelligent control system;

[0024] The exhaust pipe 3 and the intake pipe 2 are connected to the exhaust port and the intake port of the scroll compressor 1 respectively;

[0025] The pressure sensor 4 is installed on the intake pipe 2 to detect the intake pressure; the temperature sensor 5 is installed on the exhaust pipe 3 to monitor the operating temperature of the scroll compressor 1;

[0026] The intelligent control system is connected to the pressure sensor 4, the temperature sensor 5 and the scroll compressor 1. By receiving the data transmitted by the sensors, it analyzes the working status of the scroll compressor 1 in real time and automatically adjusts the working parameters of the scroll compressor 1 to achieve efficient and energy-saving operation.

[0027] The intelligent control system uses a PID (proportional-integral-differential) control algorithm to automatically adjust the operating parameters of the scroll compressor based on sensor data. The mathematical expression is:

[0028]

[0029] Among them: K p It is the proportional gain, which is used to adjust the proportional relationship between the intensity of the control action and the error.

[0030] The application process of the PID control algorithm is as follows:

[0031] Error calculation: The intelligent control system first compares the set target values of intake pressure, exhaust temperature, etc. with the actual measured values of pressure sensor 4 and temperature sensor 5 to calculate the error e(t);

[0032] PID calculation: The control system then uses the PID algorithm to calculate the control signal u(t) based on the error e(t). This control signal will be used to adjust the operating parameters of the scroll compressor 1.

[0033] Parameter adjustment: Based on the control signal u(t), the intelligent control system automatically adjusts the speed, refrigerant flow rate and other parameters of the scroll compressor 1 to reduce the error e(t) and make the working state of the compressor gradually approach and stabilize at the set target value;

[0034] Feedback loop: The entire process is a closed-loop feedback control process. The intelligent control system continuously receives sensor data, calculates errors, generates control signals and adjusts compressor parameters until a stable operating state is achieved.

[0035] Summary: By adopting the PID control algorithm, the intelligent control system can more accurately adjust the operating parameters of the scroll compressor based on sensor data such as intake pressure and exhaust temperature, achieving efficient energy saving and stable operation.

[0036] Specifically, the pressure sensor 4 is installed on the intake pipe 2 through a threaded sealing connection to ensure accurate detection of the intake pressure and adjust the working parameters of the scroll compressor 1 according to changes in the intake pressure to optimize the intake efficiency and overall performance of the scroll compressor 1.

[0037] Specifically, the temperature sensor 5 is installed on the exhaust pipe 3 through a threaded sealing connection to accurately monitor the exhaust temperature of the scroll compressor 1, and adjust the temperature through an intelligent control system to prevent the scroll compressor 1 from overheating, protect the equipment from damage, and improve energy efficiency.

[0038] As can be seen from the above, this device integrates a scroll compressor, intake and exhaust pipes, pressure and temperature sensors, and an intelligent control system. Through precise pressure and temperature monitoring, the working status of the compressor can be grasped in real time. The pressure sensor is installed in the intake pipe to ensure optimal intake efficiency; the temperature sensor is placed in the exhaust pipe to prevent overheating and ensure equipment safety. The intelligent control system automatically adjusts the compressor operating parameters according to the sensor data, which not only achieves a significant reduction in energy consumption, but also improves the overall performance and stability of the equipment.

[0039] Example 2: This example is basically the same as the previous example, except that the intelligent control system further includes a data storage module for recording various parameters during the operation of the scroll compressor 1, including intake pressure, exhaust temperature and operating parameter adjustment records, for subsequent data analysis and fault diagnosis.

[0040] Specifically, the intelligent control system has a remote monitoring function, which can transmit the operating status data of the scroll compressor 1 to a remote server through the network, thereby realizing remote monitoring and fault diagnosis, and improving maintenance efficiency and convenience.

[0041] Specifically, the intelligent control system also includes a user interaction interface, allowing the user to set the working mode of the scroll compressor 1, view real-time operating data, and receive fault alarm information through the touch screen, thereby improving user experience and operability of the equipment.

[0042] From the above, it can be seen that this embodiment further enhances the functions of the intelligent control system while maintaining high efficiency and energy saving. The newly added data storage module comprehensively records the operating parameters, providing strong support for data analysis and fault diagnosis. The addition of the remote monitoring function enables the operating status of the equipment to be transmitted to the remote server in real time, facilitating remote monitoring and troubleshooting, greatly improving maintenance efficiency and convenience. In addition, the design of the user interaction interface allows users to easily set the working mode, view real-time data, and receive fault alarms, which not only improves the user experience, but also enhances the operability and interactivity of the equipment.

At the same time, users can also set the working mode, view real-time operating data, and receive fault alarm information through the user interface.

[0057] Regularly perform maintenance and service on the device, including cleaning the intake and exhaust ducts, checking whether the sensors and electrical connections are in good condition, etc., to ensure long-term and stable operation of the device.

[0058] 4. Fault diagnosis and troubleshooting

[0059] When the scroll compressor 1 fails or operates abnormally, the intelligent control system will promptly issue an alarm message and notify the management personnel through the user interaction interface or remote monitoring function.

[0060] Managers can analyze and diagnose based on the alarm information and historical data in the data storage module, determine the cause of the fault and take appropriate troubleshooting measures.

[0061] If the fault cannot be resolved on site, you can use the remote monitoring function to request technical support or arrange for professional repairs.
