The Statistic Analysis of Instruments and Temperature Measurement of Freezer Wall Attached by Dry Ice Gel

Abstract

The need for electrical energy in Indonesia is increasing rapidly, and the use of electrical energy will increase carbon dioxide gas emissions by around 1.3% each year, which causes environmental damage. The electricity usage sector in households is higher than in industry and transportation. The need for electricity in households will increase from 49% in 2018 to 58% in the BAU (business as usual) scenario and 61% in the RK (low carbon) scenario in 2050. The leading cause of the high use of electrical energy in households is the use of cooling equipment such as air conditioners, refrigerators, and freezers. One strategy to increase energy efficiency that can be used in cooling equipment such as freezers is using phase change materials (PCM). The method in this research used phase change material of dry ice gel to maintain the temperature in the freezer although the electricity was off. The results showed that the dry ice gel PCM maintained the temperature under zero degree.
