Prevention of unpowered reverse rotation in compressors

InactiveUS20060222510A1prevent reversalrule out the possibilityFluid parameterOscillating piston enginesDrive motorAir conditioning
The shutdown of a compressor (10) installed in a refrigerant circuit (2) in air conditioning or refrigeration system is controlled so as to prevent unpowered reverse rotation of the compressor. Prior to terminating electric power to the compressor drive motor (24), the pressure within the system is relieved and substantially equalized across the compressor, thereby eliminating the possibility of unpowered reverse rotation of the compressor at shutdown. Pressure relief and equalization may be achieved by reducing the operating speed of the compressor to a low forward speed for a period of time prior to deenergizing the compressor drive motor. Pressure equalization may also be achieved by driving the compressor in reverse rotation prior to deenergizing the drive motor.

This invention relates to the field of integrated structural and functional design of aero-engines, and discloses a compressor rectifier blade angle adjustment structure and method based on piezoelectric materials. The method utilizes the extension, contraction, or bending deformation of a first and second active pawl to drive the rectifier blade, equipped with ratchet wheels, to rotate to the desired angle. Furthermore, each rectifier blade is designed with two ratchet wheels, which work together to allow the blade to freely rotate in both directions. The first and second anti-return pawls effectively prevent reverse rotation and backtracking during rectifier blade angle adjustment. This invention transforms the reciprocating motion of the first and second active pawls into intermittent rotation of the rectifier blade along a certain direction, moving step by step and accumulating the rotation angle. This allows the rectifier blade angle adjustment range to reach 360°, and the adjustment accuracy can be adjusted by modifying the number of ratchet teeth as needed. This adjustment structure is superior to traditional adjustment structures, and the adjustment method has the advantage of high positioning accuracy.

Compressor start / stop control methods, devices, air conditioning equipment and storage media

PendingCN122670182AAddressing issues with high risk of injuryprevent reversal
This application relates to a compressor start-stop control method, device, air conditioning equipment, and storage medium. The method includes: upon receiving a compressor stop command, determining in real time whether the compressor's stop rotation state is reversed based on the electrical signal timing of the permanent magnet synchronous motor inside the compressor. If it is reversed, the permanent magnet synchronous motor is controlled to generate electricity according to the braking mode. Since the high and low pressure difference in the system drives the pump body and drives the built-in rotor to rotate in the opposite direction after the compressor stops, the rotor is dragged in reverse by the external force of the pressure difference. The permanent magnet synchronous motor passively becomes a generator. At this time, actively controlling the permanent magnet synchronous motor to enter the controllable power generation mode can generate electromagnetic resistance torque opposite to the reverse direction, which can offset the thrust of the pressure difference and prevent the rotor from continuing to reverse. This solves the problem that existing compressor stop anti-reverse methods cannot detect and prevent reverse in real time, resulting in a high risk of mechanical damage.
