Refrigerator technology continues to develop towards a better and more efficient direction. Refrigerator must be given a touch of innovation to get the best performance. This study aims to obtain data on the performance of refrigerators with double pipe heat exchanger innovation and variations in the length of the capillary tube. The research method used is experimental. The experiment was carried out on a 1/6 PK refrigerator trainer, the ratio of the size of the double pipe heat exchanger was 1/4:1/2, and the variations in the length of the capillary pipe were 1.5m, 2m, 2.5m, and 2.75m. The diameter of the capillary tube is maintained at 0.028 inches. The initial refrigerant used is refrigerant R-134a, which is then retrofitted by the drop in substitute method by refrigerant R-1270 as the refrigerant being tested. The load used is 1.5L mineral water. The results showed that the use of 1.5 m capillary pipe and double pipe heat exchanger was able to increase the value of the refrigeration effect up to 49%, the value of work efficiency (CoP) increased by 22% compared to the refrigerator system using R-134a. Electric power consumption has decreased by up to 25%, thereby reducing the cost of electricity bills. This study has shown that the use of refrigerant R-1270 in a refrigerator with a double pipe heat exchanger and a long capillary tube with a diameter of 0.028 inches improves performance and saves electricity consumption.
