Hey Bowman I need some info. I made a few calculations with R134 and R22 freons. From Molliere diagrams for those freons I draw theoretical cooling cycle and I calculate cooling number for R134 to be 4.5 and for R22 14.9 , so huge difference just by changing freons so that means if I need let say 250W of cooling power that compressor power for R22 is just ~16W is . So How do you controll all that exesive power from compressor if you pick one like you said 0.25 HP (183W) ... by lenght of capilary tube?
And then I looked at NH3 that is even better cooling nuber is ~30 for that gas. And one good thing about NH3 you could quickly smell if something is leaking.
If I'm totaly wrong how do you pick up the right compressor?
