Abstract :

Active Magnetic Refrigeration Apparatus is a novel device that has zero vapor pressure and causes, zero ozone depleting gases. The magnetic refrigerator has the prospective to become a realistic choice instead of present vapor compression refrigeration systems. In the present study a Magnetic refrigerator designed and constructed in Iraq (the first one as our knowledge), used as laboratory device to investigate the effects of many operational parameters on its performance. The results indicated that an experimental parallel plate AMR device demonstrates the high performance, and due to their relatively low pressure drop to the heat transfer performance and to be quite versatile, in terms of operational parameters and various aspects of the cooling capacity. The hot end had a prescribed temperature of 299K a zero cooling loads applied at the cold end. So, temperature span observes be about 11K, which evaluated as the difference temperature between the hot and cold ends of the magnetocaloric regenerator. All thermal losses through the regenerator housing and the cold end go to the ambient through the hot end, within an insulated cold end, due to, no heat exchangers were used at the cold and hot ends. Therefore, this test machine used to measure the no-load temperature span.
