Definitions
- Fig. 1 conceptually illustrates exemplary compositions for MnNiSi-based alloys that exhibit magnetostructural transition temperatures at less than 400 K, extraordinary magnetocaloric properties and an acute sensitivity to applied hydrostatic pressure, in accordance with principles of the invention.
- Fig. 13 illustrates composition dependent temperature dependency
- Fig. 15 shows relative cooling power (RCP) as a function of temperature at ambient pressure for (MnNiSi)i_ x (CoFeGe) x in comparison to other known magnetic refrigerant materials, with T a being the temperature corresponding to -ASmax for a field change of 5 T, illustrating a remarkable enhancement in the effective RCP with the application of 1 kbar pressure, and providing a linear fit of the composition-dependent values of the RCP;
- RCP relative cooling power
- Two new MnNiSi multicaloric compositions are provided. They include
- Z may comprise up to 15% (by mass) of the formulation.
- the variable x may be from 0.30 to 0.50 in the formulation containing Co, and from 0.40 to 0.65 in the other formulation.
- Each formulation is based upon MnNiSi.
- the elemental subscripts are 1 or about 1, meaning that the subscript variables a, ⁇ , y, ⁇ , ⁇ , v are 0 or about 0.
- a large value of -AS detected at ambient pressure is associated with the first-order magnetostructural transition.
- the values of -AS are in good agreement as estimated using the two different equations, which lends justification to the use of the Maxwell relation with the invention.
- a large, field-induced isothermal entropy change (-AS) occurs in the vicinity of the MST.
- the observed pressure-induced, twofold increase of ⁇ ⁇ AS ⁇ from 44 to 89 J/kgK is associated with a large volume change during the MST from a FM orthorhombic to a PM hexagonal phase.
- the application of 2.4 kbar of pressure induces a relative volume change of AV/V -7% in the sample, and results in an enormous increase in AS.
- Hydrostatic pressure acts as a parameter that leads to a giant enhancement of the magnetocaloric effect in (MnNiSi)i- x (MnFeGe) x , and is associated with an extreme volume change (-7%) in the vicinity of the MST.
- the pressure-enhanced magnetocaloric effects are accompanied by a shift in transition temperature, an effect that may be exploited to tune the transition to the required working temperature, and thereby eliminate the need for a given material to possess a large MCE over a wide temperature range.
- Fig. 13 illustrates composition dependent temperature dependency
- Fig. 15 shows relative cooling power (RCP) as a function of temperature at ambient pressure for (MnNiSi)i_ x (CoFeGe) x in comparison to other known magnetic refrigerant materials, with T a being the temperature corresponding to -ASmax for a field change of 5 T, illustrating a remarkable enhancement in the effective RCP with the application of 1 kbar pressure, and providing a linear fit of the composition-dependent values of the RCP.
- the relative cooling power (RCP
- Fig. 17 illustrates barocaloric effects for (MnNiSi)i.
- x (CoFeGe) x (x 0.40) with isothermal entropy changes at increasing pressures, for both heating and cooling, showing high maximum values, a width of about 25 to 30 K, depending upon composition variation.
- the material exhibits acute sensitivity to pressure, as clearly shown by Fig. 18, which illustrates maximum barocaloric effects for (MnNiSi)i.
- the induced magnetic field must be controllable, by either moving the source 115 relative to the material 105, or moving the material 105 relative to the source 115, or electrically controlling the magnetic field in the case of an electromagnet.
- the working material 105 heats up when the magnetic field is applied and cools down when the magnetic field is released.
- heat is transferred from the working material 105 to a flowing fluid in thermal communication with a heat exchanger on the hot side 125 of the unit.
- heat exchanger on the cold side 125 of the unit When the working material 105 cools, heat is transferred to the working material 105 from a flowing fluid in thermal communication with a heat exchanger on the cold side 125 of the unit.
- fluids flowing through cold 120 and hot side 125 heat exchangers provide sources for cooling or heating.
