Problems solved by technology

Due to the difference in the Curie temperature point of each layer in the multi-layer regenerator, when the system is started, when the Curie temperature point of the magnetothermal working medium is close to or the same as the ambient temperature, the magnetocaloric effect of the magnetocaloric working medium is significant; but When the difference between the Curie temperature point of the magnetocaloric working medium and the ambient temperature is large, the magnetocaloric effect of the magnetocaloric working medium is very weak, and even cannot exert the magnetocaloric effect, which makes the cooling rate of the magnetic refrigeration system slower

Abstract

The magnetic refrigeration system that can pre-cool the magnetic-thermal working medium provided by the present invention installs the regenerator, the corresponding cold storage medium and the flow pipeline, and pre-cools the magnetic regenerator before the system is formally refrigerated, so that the magnetic regenerator can Establish a temperature span; and make the temperature of the magnetocaloric working medium in each layer in the magnetic regenerator close to its own Curie temperature, so that the magnetocaloric working medium in each layer can fully exert the magnetocaloric effect, and the magnetocaloric working medium in the refrigeration process The magnetocaloric effect is remarkable; the above-mentioned magnetic refrigeration system that can precool the magnetocaloric working fluid not only meets the large temperature span refrigeration, but also realizes rapid refrigeration when it is officially refrigerated.

Description

technical field [0001] The invention relates to the technical field of magnetic refrigeration, in particular to a magnetic refrigeration system capable of precooling magnetic and thermal working fluids. Background technique [0002] Magnetic refrigeration technology is a solid-state refrigeration method based on the physical properties of materials. It uses water and other environmentally friendly media as heat transfer fluids. It usually has zero global warming potential, zero ozone depletion potential, intrinsically high efficiency, low noise and low vibration. , as an emerging green and environmentally friendly refrigeration technology, more and more attention has been paid to it. [0003] The magnetocaloric effect is a thermal effect in which the temperature of a magnetocaloric material increases when it enters a magnetic field and decreases when it is removed from the magnetic field. Materials with this thermal effect are called magnetocaloric materials, and magnetocal...
