<P>PROBLEM TO BE SOLVED: To provide a magnetic heat pump apparatus capable of improving operation efficiency. <P>SOLUTION: A cycle operation is performed which sequentially repeats the following steps: a first step in which a flow of a refrigerant is stopped by a pressure valve 42a and a pressure accumulation tank 41a and magnetization is performed by a magnetic field application removing means 32; a second step in which magnetization is performed at an increase rate in accordance with a flow rate of the refrigerant while the pressure valve 42a is opened so that the refrigerant is distributed from the other end 311b in a work chamber 311 to one end 311a; a third step in which a flow of the refrigerant is stopped by a pressure valve 42b and a pressure accumulation tank 41b and demagnetization is performed by the magnetic field application removing means 32; and a fourth step in which demagnetization is performed at a decrease rate in accordance with a flow rate of the refrigerant while the pressure valve 42b is opened and the refrigerant is distributed from one end 311a in the work chamber 311 to the other end 311b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
