The power consumption of an air conditioner in an electric vehicle has a considerable impact on the cruising range. A high-performance magnetic refrigerator is therefore one of the important technologies needed for future electric vehicles. The requisite conditions for an in-vehicle magnetic refrigerator are higher with respect to cooling power density, temperature difference between the hot and cold sides, transient properties, and coefficient of performance than those of household refrigerators or home air-conditioners. To date, a number of experimental and computational studies have been presented concerning magnetic refrigeration models in which heat derived from the magnetocaloric effect is transported between cold side and hot side heat baths by means of a refrigerant. The authors have devised a model without a refrigerant in which heat is transported from the cold to the hot side through well-controlled thermal switches. The heat transport characteristics were investigated under an ideal condition and compared with those of a conventional model that included a refrigerant. The concept and main features of this new model that operates without a refrigerant are described.
