Abstract

Refrigeration technique is a technique for regulating air temperature in accordance with desired needs, covering the needs of rooms in offices, in industry, shops and others such as processing needs for food preservation, including service/production, maintenance and quality control. In a cooling system (AC), there are a series of main components to support the working system, namely the compressor, condenser, filter drainer, expansion valve and evaporator. The five components that are of concern in this study are the capillary tubes. The function of the capillary tube is to reduce the pressure and reduce the temperature of the system. The purpose of this study was to determine the performance of the refrigeration system in a refrigerator machine through capillary tube variations for a diameter of 0.026 inches, 0.028 inches and 0.031 inches. By varying the diameter of the capillary tube, it can be seen that the coefficient of performance (COP) and Energy Efficiency Ratio (EER) values, cooling capacity (Cooling Capacity), refrigeration effect and system efficiency.The refrigerator used in this study uses a vapor compression cycle and uses a compressor with a power of 1/8 PK. The method used is the experimental method where experiments are carried out on the refrigerator by changing the capillary tube for three types of diameter sizes that are planned to determine the performance of the refrigerator with each size of the capillary tube. The research results show that in a capillary tube with a diameter of 0.026 inches, Coeficient of Performance (COP) was 6.43, Refrigeration Efficiency 87.11%, cooling capacity 3.87 kW, and refrigeration effect 175.94 kJ/kg. For capilarry tube with a diameter of 0.028 inches, Coeficient of Performance (COP) was 7.72, Refrigeration Efficiency 90.29%, cooling capacity 4.03 kW, and refrigeration effect 183.16 kJ/kg. In a capillary tube for a diameter of 0.031 inches, Coeficient of Performance (COP) was 6.47, Refrigeration Efficiency 75.69%, cooling capacity 3.99 kW, and refrigeration effect 181.57 kJ/kg.
