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.
