Morphing Air Conditioner into Autocascade System

[n00b 0f l337]

So lets see, if we take an average of pointblanks, call it 125w @ -90C, we can see that Mytek's does -12C better, and draws a bit more then half the energy. Autocascade really is quote amazing isn't it. Whats the max load you can hold though blank? And I'm surprised you don't have much better results coming out of that cascade.

Yep, about 1/2 the energy. I think this gets even better when designing for colder temperatures (-130C to -150C).

I should mention that there was a change in the final captube sizing I used on the AC-2 unit. I made a last minute decision, and increased the flows on the last 3 captubes (decreased length). Here is a chart with what I used:

And here is the heat exchanger info, as well as specs on the 115V LG QA090C rotary compressor I used (notice the rated load current of 5.2 Amps --- I still have some breathing room):

Edit: I gave an average spec on the length of the HXC's. In reality AUX and Cascade #1 were slightly longer, and Cascade #2 and #3 were slightly shorter. Increasing the length of all the heat exchangers would probably yield even better loaded temperatures. Keep in mind that the pressure drop, which is not beneficial, will also increase with added length.
