distributor for 2 evaporators

[19730206]

I need connect 2 evaporators in parallel. Refrigerating cabinet uses 1 compressor and capillary tube as metering device . Does anybody knows how I can calculate and make distributor with capillary tubes for these evaporators?
Thanks for any advice

I have not seen a multi-circuited coil fed by a single or multiple cap tube and distributor arrangement. Normally, dual coils are fed by thermal expansion valves (TEV or TXV). Using one or two TXV's and two distributors (one for each coil) would suit your requirements Iam sure.
But I have only been desiging refrigeration systems for about 26 years. I have not seen everything.

They have sizing tips and more to help you with you'r refrigeration design.

You don't need adistributer ..you can braze both cap tubes in 1-1/4" liquid line however the most important thing to determine is that cap tubes are sized for a particular refrigerant by compressor HP, so if both evaps are twins then it's only a matter of looking up the required size cap tube from this web site;
