A refrigerating method of a heat-torsion refrigerating apparatus according to claim, comprising the steps of,
1) The left motor drives the left end disc 3 and the right end disc 4 to rotate, so that the refrigerating element 6 is driven to rotate, the refrigerating element 6 is brought into the twisting area by the two end discs and twisted under the action of the driving part, the heat is released outwards in the process, and the temperature of the cooling medium is increased due to heat absorption; the refrigeration element 6 is untwisted when entering a refrigeration zone to refrigerate, and the cooled medium flows through the refrigeration zone to cool;
2) The refrigerating capacity is controlled by changing the twist of the refrigerating element 6, and the control method is as follows:
a. the rotational speeds of the left motor 16 and the right motor 17 are adjusted to control the twisting speed: the twist of the refrigerating element 6 is changed to change the refrigerating capacity, and the control part controls the rotation speeds of the motor of the refrigerating main body part and the motor of the driving part;

The working principle of the invention is as follows:
the twisting and heating refrigeration does not use a refrigerant, but makes the materials twist and untwist to realize the change of the austenitic state and the martensitic state of the refrigeration element, and the twisting process emits heat, and the untwisting process absorbs heat, so that the refrigeration or heating is realized. The left motor 16 drives the two end plates to rotate so as to drive the refrigerating element 6 to rotate, the refrigerating element 6 is brought into a twisting area by the two end plates, the twisting is performed under the action of the driving part, and the twisting speed is accelerated and decelerated to 0 along with the process that the meshing area of the movable plate of the refrigerating element and the conductor plate of the driving part is from small to large to small. In the process, the heat is released outwards, and the temperature of the cooling medium rises due to heat absorption; when entering the refrigerating area, the cooling medium is untwisted to cool, and the cooled medium flows through the refrigerating area to cool. By changing the twist of the cooling element 6 to thereby change the cooling capacity, there are two methods of changing the twist: 1. the control part controls the rotation speeds of the left motor 16 and the right motor 17; 2. the spacing, i.e., the air gap, between the conductor disc 18 and the end disc is changed.
The invention adopts permanent magnet speed regulating equipment, and the working principle is as follows:
permanent magnet speed regulation drives are torque transmissions from the motor to the load through an air gap between the conductor and the permanent magnet. There is no mechanical link between the drive (motor) and driven (load) sides in this technique. The working principle is that a permanent magnet (rare metal oxide ferroboron neodymium permanent magnet) at one end interacts with an induction magnetic field at the other end to generate torque, and the transmitted torque can be controlled by adjusting an air gap between the permanent magnet and a conductor, so that the load speed is adjusted; in addition, the rotational speed of the load may also be changed by changing the rotational speed of the motor.
The permanent magnet speed regulation driving device mainly comprises a conductor rotor, a permanent magnet rotor and a controller. The conductor rotor is fixed on the motor shaft, the permanent magnet rotor is fixed on the load rotating shaft, and a gap (called an air gap) is formed between the conductor rotor and the permanent magnet rotor. The motor and the load are changed from the original hard (mechanical) link to the soft (magnetic) link, and the change of the output torque on the load shaft can be realized by adjusting the air gap between the permanent magnet and the conductor, thereby realizing the change of the load rotating speed. From the above analysis it is known that by adjusting the air gap an adjustable, controllable, repeatable load speed can be obtained.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
