Chiller Cap Tube

Sorry if this is an obvious question but digging through this subforum was getting me nowhere. I've got a friend of mine in the process of building a chiller utilizing a 1/10 HP compressor, matched condenser, and cap tube as his metering device. Using a TXV is out of the question due to costs, he has the captube and wants to use it, so that being said how do cap-tube lengths work with chillers. He'll be using r134a and I'd say the heatload will be ~300 watts, so would we be looking at ~6 feet of 0.031? Figured a short length would increase the massflow, giving this little compressor the chance to carry the load albeit at temps around ambient. TXVs are so much simpler, just built a TXV chiller and it was a dream to tune

Definitely a very short length; sorry but I don't know much more'n that :p.

But 300W on a 1/10 hp compressor? Is it just me, or is that insanity? (Could be just me

)

Not looking for much more than a few degrees below ambient I believe. It's his first chiller and he used parts that he could get very cheap I believe. Anyone? I know this section doesn't get much traffic but damn

HP means nothing, how much energy can it move is the data that is realivant, then what temp rang? Low, Med, High?
