Description

Abstract: Manufacturing process and performance analysis of a non-frost refrigeration system are presented in this paper. Main objectives of this research were to suggest better refrigerant as well as propose a technique for further reduction of the power consumption of the system. Performance of the refrigeration system was evaluated for Tetra-fluoro-ethane and Isobutene refrigerant. From the experiment, it is found that, coefficient of performance of the system with Isobutene is better than the coefficient of performance with Tetra-fluoro-ethane. Not only that, Tetra-fluoro-ethane is higher global warming refrigerant than Isobutene. In addition, in this paper, it is shown that, if capacitor is added to the electric circuit then power consumption of the system is dramatically decreased. To reduce the power consumption of the system, capacitors of different micro-farad were added and optimum one was selected through experiment. Maximum coefficient of performance was found for Isobutene with 10μF capacitor. In case of Isobutene, 47.736% energy was saved. Hence, it is proposed to add a capacitor to the circuit and use Isobutene rather than Tetra-fluoro-ethane as refrigerant for better performance of the system.
