what size of a cross flow fan require to generate 1300 CFM
on 24 volt DC from an A/C box or what is the formula.

What do you mean by a "cross flow" fan?

Do you mean a centrifugal fan with non-axial flow?

 

[solcool]

I mean Air Wheel or sleave fan or Air Curtain long and nerrow

There is really no formula for fan sizes.

There are many fan blade types (radial, backward inclined, forward curved, axial and etc) depending upon the use for the fan.

Fan laws are here:

tying to clone an LG ductless split? They run on about 30VDC

Take the "V" out of HVAC and you are left with a HAC(k) job.

There are probably some theoretical formulas for fan air flow. However the fan manufacturer's literature is the place to start. You need to know how much air you want to move and what static pressure rise the fan is required to develope.
