Abstract

A magnetic refrigeration control system, includes: a first magnetocaloric bed; a pipe, arranged through the first magnetocaloric bed; a coolant, flowing in the pipe; a pump, driving the coolant with a pumping speed; a valve, adjusting a flow period of the flowing coolant; a magnetic module, providing an increasing magnetic field to the first magnetocaloric bed during a magnetization period and providing a decreasing magnetic field to the first magnetocaloric bed during a demagnetization period; and a sensor, detecting a fluid pressure of the coolant flowing in the pipe, the temperature of a refrigerator, and a flowing rate of the coolant flowing in the pipe; and a controller, adjusting the pumping speed, the flow period, the magnetization period, and the demagnetization period according to the temperature, the fluid pressure, and the flowing rate in real time. A magnetic refrigeration control method is also disclosed.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The disclosure relates generally to magnetic refrigeration technologies, and more particularly relates to the control of a magnetic refrigeration system with better cooling performance.[0003]2. Description of the Related Art[0004]Present refrigeration technology, for example, a refrigerator, a freezer, a room air conditioner, a heat pump and the likes, mainly employs a gas compression / expansion cycle. However, a serious problem of environmental pollution is caused by specific Freon gases discharged into environment for refrigeration technology based on the gas compression / expansion cycle. Recently, magnetic refrigeration technology has been introduced as a highly efficient and environmentally friendly cooling technology. Magnetic refrigeration technology adapts a magnetocaloric effect (MCE) of magnetocaloric materials (MCM) to realize refrigeration cycles.[0005]Nowadays, the operation frequency of the MCM based magnetic...
