    Cascade system Design



    Any one can help me designing for two stage cascade system .
    Required Capacity 10 TR
    Required Temperature -70 Deg c
    Ambient Temperature +40 deg c

    I like to use screw compressor of Bitzer / Frascold .
    I stage 75 HP
    II Stage 60 HP.

    What Refrigerants to be used?
    What is the capacity of Intermediate Condenser?
    What Oil to be Used?
    SS evaporator or Copper Tube ?
