Abstract
HFCs group refrigerants are still widely used in refrigerated pickup trucks. This refrigerant is a synthetic chemical and has a high potential to cause global warming and damage the ozone layer. This study aims to obtain performance data from the use of HCs as refrigerant in refrigerated pickup trucks. The research was conducted experimentally on a pickup truck with a 1500 cc engine capacity. The size of the refrigerated room is 2300 mm long, 1500 mm wide and 1400 mm high. A commercial refrigeration system (C-250e MAX, Thermo King Europe, Belgium). The size of the evaporator, which consists of a cold air supply fan and an intake fan, is 133 mm long, 985 mm wide and 525 mm high. The cooling capacity is 2770 W. The volumetric flow rate of cold air is 1100 m3/hr. The test started at 9 am and the temperature value in a gallon of water was measured for 120 minutes. The results showed that the optimal refrigerant filling was the use of R290 (35%) and R1270 (20%). The value of the coefficient of system performance obtained from the use of the two variations of HCs is 4. Thus, refrigerant HCs R290 and R1270 can replace refrigerant HFCs in refrigerated pickup trucks with refrigerant mass variations of R290 (35%) and R1270 (20%).
