ANALISIS BEBAN PADA BOX PENDINGIN PRODUK INJECTION COVER INNER LOWER HVAC DAN KEBUTUHAN EVAPORATOR MESIN PENDINGIN

This study aims to analyze the cooling capacity ofthe cooling box products ofInner Cover Lower HVAC products made from Polyprophelene (PP) type plastic. In addition, this study also analyzes the specifications of the air-cooled engine evaporator. This product cooler box uses an Air Conditioner 34 PK with a vapor compression cycle that has a cooling effect and a heating effect. The cooling effect is served by a heat exchanger called the evaporator; the process that occurs in the evaporator is the change in the phase of the refrigerant / fluid from the liquid to vapor (evaporation / evaporation). Evaporator specifications analyzed by type of water-cooled Fin coil using R-22 refrigerant. The method used to achieve the goal is through thermodynamic calculations and calculations on the evaporator. From the calculation results, the evaporator specification used is a Copper tube with a nominal diameter of 1/4 inch type L, Outer diameter of 0.25 in. (6.35mm), Inside diameter 0.20 in. (5.13 mm), and tube wall thickness 0.61 mm, Surface area offins 0,00018834 m2 with spacing between fins 1.2 mm, fin length 22 mm and width of fins 10 mm, total length of copper pipe 88,073 m, dimensions of evaporator used 410x210x50 mm.
