Title:
MAGNETIC HEAT PUMP APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/135386
Kind Code:
A1
Abstract:
[Problem] To provide a magnetic heat pump apparatus that solves a problem arising when a rotary valve is in use and that aims to improve efficiency. [Solution] The present invention is provided with: magnetic work bodies 11A, 11B which are provided with a magnetic work substance 13 having a magnetocaloric effect and through which a heat medium is circulated; a permanent magnet 6 which changes the magnitude of a magnetic field to be applied to the magnetic work substance; a displacer 8 which moves the heat medium reciprocally between a high-temperature end 14 and a low-temperature end 16 of the magnetic work bodies; and external heat medium circulation circuits 27, 28 which respectively have external heat exchangers 19, 22 and which circulate a second heat medium. The external heat medium circulation circuits cause heat to be exchanged between the second heat medium and the heat medium in the magnetic work bodies, and then circulate, to the external heat exchangers, the second heat medium having undergone the heat exchange.
