A method for refrigerating a torsional heating refrigerating device as defined in claim, comprising the steps of,
1) The left motor drives the left end disc 3 and the right end disc 4 to rotate, so as to drive the refrigerating element 6 to rotate, the refrigerating element 6 is twisted under the action of the driving part when being brought into a twisting zone by the two end discs, heat is released outwards in the process, and a cooling medium is heated because of heat absorption; the refrigerating element 6 is untwisted when entering the refrigerating area so as to refrigerate, and the cooled medium flows through the refrigerating area to reduce the temperature;
2) And the twist of the refrigerating element 6 is changed to control the refrigerating capacity, and the control mode is as follows:
a. the rotating 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 so as to change the refrigerating capacity, and the control part controls the rotating speed of the motor of the refrigerating main part and the motor of the driving part;
b. the twisting speed is controlled by adjusting the air gap between the permanent magnet conductor disc 18 and the right end disc 4: the link mechanism is driven by controlling the adjusting motor, so that the right motor 17 is driven to move on the guide rail, and the distance between the permanent magnet conductor disc 18 and the right end disc 16 is controlled.
The working principle of the invention is as follows:
the torsional heating refrigeration does not use a refrigerant, but twists and untwists the material to realize the change of the austenite state and the martensite state of the refrigeration element, releases heat in the twisting process, absorbs heat in the untwisting process, and thus, the refrigeration or the heating is realized. The left motor 16 drives the two end discs to rotate so as to drive the refrigerating element 6 to rotate, the refrigerating element 6 is twisted under the action of the driving part when the refrigerating element 6 is brought into a twisting area by the two end discs, and the twisting speed is accelerated and decelerated until the twisting speed is 0 along with the meshing area of the movable disc of the refrigerating element and the conductor disc of the driving part from small to large. In the process, heat is released outwards, and the cooling medium is heated due to heat absorption; and the cooling medium flows through the refrigerating area to be cooled. By varying the twist of the cooling element 6 and thus the cooling capacity, there are two ways of varying the twist: 1. the control part controls the rotating speed of the left motor 16 and the right motor 17; 2. the spacing between the conductor disc 18 and the end disc, i.e. the air gap, is changed.
It should be noted that the invention adopts a permanent magnet speed regulation device, and the working principle is as follows:
permanent magnet adjustable speed drives achieve torque transmission 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, namely, a ferroboron neodymium permanent magnet) at one end and an induced magnetic field at the other end interact 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; alternatively, the rotational speed of the load may 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 reserved between the conductor rotor and the permanent magnet rotor. Therefore, the motor and the load are changed from the original hard (mechanical) link into the soft (magnetic) link, and the output torque change on the load shaft can be realized by adjusting the air gap between the permanent magnet and the conductor, so that the load rotating speed change is realized. 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 appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
