A room temperature magnetic refrigerator deserves our attention as a refrigerator without having to use environmentally hazardous fluids, since magnetic materials showing a giant magnetocaloric effect at room temperature have been developed in the last few years. We have been investigating a performance of a magnetic refrigerator that uses water as a coolant. In the present study, we clarify the influence of heat exchanging period and water flow rate on the refrigerator performance.
