An Experimental Study on Heat Transfer Characteristics of Refrigerant R134a in a Microtube Evaporator

The heat transfer characteristics of a microtube evaporator use refrigerant R134a were studied experimentally. This evaporator was made from copper tubes and aluminum foils with overall dimensions (L*W*H) of 259.3*43*200mm. The evaporator has 10 passes, each pass including 8 copper pipes (with hydraulic diameter of 0.82mm) and 83 aluminum foils (with the thickness of 0.3 mm); the distance between the two foils is 2.6 mm
