Heat load and capillary tube

[kay86]

Hey guys, I'm trying to calculate the capillary tube size for my project but I'm not sure I'm entering the correct data into the Secop tool because the recommended capillary size seems kinda off. Am I wrong assuming that I can treat the cooling capacity as heat load on this tool? The other data is correct because I need to aim for -35 C for the evaporator and +35 C for the condenser. Thank you!

Yeah, Secop results don't look right

Amazing, that's more like it! :)

What I found more reliable for capillary tube reference is Embraco compressor handbook! Match your compressor displacement and working condition with that of Embraco and start from there! Sometime you need some length adjustment but most of the time you are good!

Off course, heat load balancing between compressor, evaporator and condenser should be done before that!
