A Comparative Study of Non-Frost Refrigerator Over the Frost Refrigerator in Economical and Environmental Perspective

Abstract

The study focuses on a comparative operation cost analysis between the non-frost and frost type refrigerator. Refrigerator is an essential equipment for food storage technique around the world. Both frost and non-frost refrigerators are widely used nowadays. However, their costing operations are not same. So the objective of this study was set to find out more economical refrigerator type that is either the frost type is economical or the non-frost type. A comparative analysis was done for both type refrigerators with the focus on the calculative results of initial cost (i.e. assembly cost, decoration cost, process cost), maintenance cost and the total 10 years’ power consumption cost. The calculated results depicted that though initial cost is found higher in non-frost inverter refrigerator, the other cost like maintenance cost as well as the overall 10 years’ power consumption cost was found to be cheaper in non-frost inverter refrigerator. Based on the experimental data it can be suggested that the non-frost with inverter type refrigerator is found to be more economical than frost type refrigerator. So it can be recommended that nonfrost with inverter type refrigerator can be used in both domestically and industrially in the minimum costing rate.
