| Abstract: | The alternative refrigerant R404A/R23 and R22/R13 was compared in the using of classical cascade refrigeration machine.It was found that the displacement of the four kinds of refrigerant was feasible.The alternative refrigerants used in machine also have a good COP and it worked steady,but some parts have to change to get a better condition. |
