My 3 stage cascade design - what you think??

Subcooling involves two factors: condensing temp and liquid temp. Higher condensing temp bad, lower liquid temp good.

Right Gents,

From that & above can I gather,

That the final stage needs to be worked out first ???

Then from that you work out what your second stage evap temp needs to be for final stage condensing ???

And the finaly you work out first stage evap temp to suit second stage condensor ???

If correct its a case of final stage at best efficiency ...... then second stage refrigerant ect can be chosen then & only then ??? still looking for best efficiency and then repeat ???
