Definitions
- This preheating and / or pre-cooling has the effect of anticipating respectively the rise and the fall of temperature of the magnetocaloric elements when they are subjected to a variation of magnetic field, which has for consequently an increase in the temperature gradient and consequently an improvement in the efficiency of the system.
- the circulation velocity of said first heat transfer fluid is advantageously varied in said hot circuit by means of a circulation pump controlled by a control box and the circulation velocity is advantageously varied.
- said second heat transfer fluid in said cold circuit by means of a circulation pump controlled by a control box.
- the device may comprise specific heating or cooling means and selected from the group comprising infrared radiation generators, electrical resistors, Pelletier plates.
- FIGS. 6A and 6B are diagrams illustrating the operation of the magnetocaloric elements without preheating, in accordance with the prior art
- FIGS. 7A and 7B are diagrams illustrating the operation of the magnetocaloric elements with preheating according to the invention.
- the distribution discs 20 comprise orifices 21 and distribution grooves 22 making it possible to connect in series, in parallel or in a series / parallel combination, the respectively hot and cold circuits of the different thermal modules 10 to each other and to the external collector circuits 31a. , 32a respectively hot and cold.
- These splitter discs 20 may be doubled and each dedicated to one of the collector circuits. They can also be formed of single-sided double discs (not shown) with a particular arrangement of orifices 21 and distribution grooves 22 to perform a similar function.
