Magnetic refrigerator air conditioning system

Abstract

The invention provides a magnetic refrigerator air conditioning system which solves the problem that magnetic working medium particles are prone to deviation in rotation, so that the magnetic working medium particles are not even. The magnetic refrigerator air conditioning system is characterized in that a hot side airtight water tank, a heat dissipating heat exchanger, a magnetic refrigerator, a heat absorption heat exchanger and a cool side airtight water tank are sequentially connected on a water conveying pipeline. The two air outlet pipes of an air cylinder are inserted into the two airtight water tanks respectively and above a liquid level, and a linear motor is used for driving the air cylinder. A servomotor is used for driving the magnetic refrigerator to rotate back and forth in the range of 180 degrees through a gear transmission system. When the magnetic refrigerator rotates to the demagnetization direction, a piston of the air cylinder operates towards an air cylinder hot side cavity. When the magnetic refrigerator rotates to the magnetization direction, the piston of the air cylinder operates to an air cylinder cold side cavity. The magnetic refrigerator air conditioning system has the advantages that the problem that the magnetic working medium particles deviate in continuous rotation is solved and the system can operate for a long time.

Description

technical field [0001] The invention relates to an air conditioning system with a magnetic refrigerator as the core. Background technique [0002] The magnetic refrigerator mentioned in the present invention refers to a brand-new refrigeration technology using magnetic materials as working fluids, which includes a fixed magnetic system, a swinging magnetic system, and channels for heat exchange media such as water channels. The magnetocaloric effect of material-gadolinium in a magnetic field, that is, the magnetic refrigeration material releases heat to the outside when it is isothermally magnetized, and absorbs heat from the outside when it is adiabatically demagnetized, so as to achieve the purpose of refrigeration. Magnetic refrigeration materials are substances with magnetocaloric effects used in magnetic refrigeration systems. Its refrigeration method is to use the magnetic entropy change of the spin system to refrigerate. Magnetic refrigeration first applies a magneti...

AI Technical Summary

Problems solved by technology

The magnetic refrigerators developed at this stage have various disadvantages. The earliest magnetic refrigerators developed are chain reciprocating, and the chain drives the reciprocating work of the magnetic refrigerators to generate great noise. Due to the friction in the system Large, so the loss is large, resulting in a low COP value of the magnetic refrigerator

The 360-degree continuous rotating magnetic refrigerator developed in the later period completely changed the operation mode of the chain reciprocating magnetic refrigerator. There are new problems in the operation of the system. Since the motor drives the rotor of the magnetic refrigerator to rotate continuously, the particles of the magnetic working medium are prone to deviation during the rotation, which makes the particles of the magnetic working medium uneven, resulting in the phenomenon that the system is not concentric. Once it is not concentric, The system will not be able to work, so the working state of the refrigerator system is unstable and cannot be operated for a long time
