Abstract :

Cooling spaces below ambient in warm climates is essential for occupant’s comfort. In the last two decades, international environment protection organizations have led an act for the intensification of research efforts on development and safe of ozone and reduce global warming. Various methods and investigations used to design new cooling technologies. Among these surveys, the Magnetic Refrigeration has received a particular interest in last few years. This technique is candidate to be an alternative and as a realistic choice instead of present vapor compression refrigeration systems. In this work, magnetic cooling process, were tested by designing and fabricating a novel prototype magnetic refrigeration prototype consisting of Gadolinium as the refrigerant material. The constructed device consists of an active magnetic regenerative with high-purity of Gadolinium plates. This test machine operated with two types of working fluids, namely distillate pure water and water/ethylene glycol mixture at the same operating conditions. The experimental results presented that the system reached the maximum observing no-load temperature span of about 11K, between the hot and cold ends of the magnetocaloric bed. The recent Magnetic Refrigerator outputs were validated by comparing it with other similar researches, and it produced good agreements.
