METHOD FOR ADJUSTMENT OF MAGNETOCALORIC REFRIGERATOR OPERATION PARAMETRES IN LABORATORY CONDITIONS AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC F25B21/00 

FIELD: heating.

SUBSTANCE: inventions are related to refrigerating equipment. Method for adjustment of magnetocaloric refrigerator operation parametres in laboratory conditions is based on superposition of magnetic field on magnetocaloric working medium, coolant pumping for its contact with working medium, organisation of heated coolant heat-exchange with environment, drain of cooled coolant into cooling chamber of refrigerator, regulation and control of refrigerator operation parametres. Working medium used is set of single-type replaceable capsules with magnetocaloric effect, which are combined in single unit. Contact of replaceable capsules is arranged along their entire surface with coolant. Optimisation of refrigerator operation is carried out by means of variation of magnetic field intensity value, coolant pumping rate, rate of replaceable capsules passage through zone of magnetic field, intensity of coolant heat transfer into environment. When minimum value of temperature is achieved in refrigerator cooling chamber, refrigerator operation parametre values that provided maximum refrigerating capacity are fixed.

EFFECT: realisation of method for adjustment of magnetocaloric refrigerator operation parametres in laboratory conditions.
