Capillary Sizing

Could anyone please help regarding selecting a capillary tube for a single door commercial freezer using a Supco Bullet Restricto Capillary Kit?

The compressor is a Cubigel GP14FB 3/8 HP on R134A but Supco's selection chart does not include this size compressor. The condenser is fan cooled but the evaporator is without a fan.

I have attached Supco's sizing chart.

Any other suggestions to what the capillary size should be or how to size the capillary would be greatly appreciated! :)

Download Dancap from Danfoss and you can calculate just what you need.

Remember that most cap tube sizing is an experiment.

Also, download the specification of that compressor if you don't already have it.

What hast his to do wit capillary sizing?
You must post this in the proper section :off topic:

Thanks for the advice Peter but I am not sure on finding some of the calculations needed with DanCap such as heat load of the system. I presume that the evaporating temp and the return gas temp will give the evaporator superheat differential??

hi
referring to tecumseh its 2 meter 0.036 internal diameter

I have always trusted to use the DANCAP program which Brian has prescribed above.

1.9m 0.042 for single feed evap on this comp

DanCap seems to be a good software, but could someone please let me know, how to estimate the heatload in a easy way for any specifik unit ? For example, it can be tricky to estimate the heat load for a bottle fridge when one wants to change the cap.tube. Kind regards / Tobias

Software or no software. The cap tube primary purpose is to meter the amount of refrigerant getting to a specific part of the refrigerant circuit. So what you need to know is how much flow through the original cap tube and match up a size and length that will do the same.
