Abstract
A parallel magnetic refrigerator assembly, includes at least two magnetocaloric stages arranged in parallel connection, each having in use a cold side and a hot side; each magnetocaloric stage including hot and cold side heat exchange circuit for carrying a heat exchange fluid to respectively receive and transfer heat from the magnetocaloric stages; wherein the hot and cold side heat exchange circuit are configured such that in use a heat exchange fluid passes in thermal contact with the respective hot and cold sides of both magnetocaloric stages. The magnetocaloric stages have substantially the same temperature spans but different cold end and hot end temperatures. In this way the device temperature span may be substantially larger than the individual temperature span of each magnetocaloric stage.
