摘要: An experimental on heat transfer characteristics of the cascade exchanger in a refrigeration system was investigated. In this paper, used couple R32/CO 2 as refrigerant: CO low stage cycle, R32 high cycle. The is double-tube type with arranging spiral shape, inner diameters are 4 mm and 8 for tube outer tube, respectively. Using microchannel evaporator, operated evaporative temperature -26°C. study, profile thermal capacity were determined. Moreover, results obtained from data good agreement theoretical calculations. These very important to calculate design using .
