Abstract
A magnetic refrigeration apparatus includes a main channel, a magnetic refrigerator, a fluid transfer mechanism connected to the main channel, and at least one control valve. A heating medium flows through the main channel. The magnetic refrigerator includes a magnetic working substance, a casing having a channel connected to the main channel, and a magnetic field modulator that applies a magnetic field variation to the magnetic working substance. The fluid transfer mechanism alternately performs a first operation of transferring the heating medium in the main channel in a first direction, and a second operation of transferring the heating medium in a second direction opposite to the first direction. The main channel includes at least one branch channel branching from a portion of the main channel between the magnetic refrigerator and the fluid transfer mechanism. The at least one control valve is connected to the at least one branch channel.
