Capillarytubes for a transcitical system

Hi

I have some expirince with some R744 refigerationsystems (subcritical) this systems has a capacity between 15-50kW. Now i would like build a transcritical system. I have a request from a client, who wants a refrigerationsysstem transcritical. His system has a capacity about 1kW. Finally i need for expansion capillarytubes.

I have some problems to calculate. Can some one help or has some one experience to calculate capillarytubes for a R744 system transcritical.

Tahnx
