View Full Version : Autocascade #3
This will be the third auto-c I am building. This time I'll use a improved phase-seperator and try a different hx design.
I got this airconditioner so far. I'll use the housing of the ac. When I replace the fan there will be enough room for the phasesep and hx.
My evap assambly + cpev from chilly should arrive this week. :)
I hope I get some cold temps until next weekend.
Does anybody know which size this hitachi rotary is?

What BTU was the whole system?

Google found this:

Not too helpful, but the capacity implies maybe 1 or 1.5HP, if I had to make a very rough guess. Either way, thats a powerful compressor. Good luck.

Thanks for the link. I wasn't able to find some info with google. :(
1hp sounds good :)
@bh2k
i duno how much btu the whole system was :(
Displacement: 16.7ml/rev :confused:
What is that in cm³ ? Don't know the used unit.

cm3 is cubic centimeters

16.7ml would be .167cm³
You sure it says 16.7ml? I dont know everything about compressors but that sems very small...

According to the online conversion, 16.7 ml is 16.7 cubic centimeters.

:D Holy cow - that's a real huge monster !!!
Post some temps if You have finnished it.......... :toast:
what does the badge on the side say of the airconditioner say. might say something like cooling power 3kw??. the label should have all sorts of specs.
i got one of those put in my house the other day. 2.75Hp 13A at 240v :slobber:
maybe 1.5Hp to 2.5Hp maybe
looks nice either ways. :toast:

that fan is huge! Never seen an a/c that big before, except maybe kayl's monstor of a dehumidifier.
Kina cool how they made the condenser curve around like that.

My apologies lol, I screwed up with that conversion. Lack of sleep does that. 16.7ml is 16.7cm³ :) :)
gkiing they are real common those airconds, they replace the box type, split systems airconds, that par is the outside unit. here they rang from 400-$2000 (1Hp-3Hp)
i think there will be a few of these things popping up in time to come.
a fridge tech i spoke to said that the new airconditioners the head units are so full off electronics and they are known to fail. they replace the hole thing under warrenty.
i got similar one just smaller, for my cascade secondstage compressor.
make sure to cut out the revercycle part of it and keep it.
i recond it will come in use for something one day, i know i did jan.

interesting.. I didn't know that small heatpump systems (< 5hp) were available to the end user.

I know my ·Matsus-hita compressor – 2P19C3R126A is 19.0 cm so I am guessing 3/4 to 1 hp but for some reason that compressor look bigger in that pic. sorry about space on name compressor every time i put name in i get bananas

So did your old system hold any loaded temps? That Rotary should kick arse;)

Na, I didn't test it. But I've already built a loadtester for the upcoming cascade!

Oh, and tody I got the parts from Chilly1 :)
http://www.mitglied.lycos.de/kryotech/Bilder/autocascade3/chilly.jpg
Now I need to build the phase-sep and the hx before I can assamble the cascade.
this is going to be a nice autocascade jan cant wait.
what condenser are you going to use?
you could use the aircon the way it is and the condenser as the phase seperator. i dont think anyone done the split condenser, and one that size :slobber:

Do you have the other half of the system? Evaporator and blower?
never mind your in germany.
Here is the hx I made. Last thing needed is a good phase seperator!

No, only the compressor/condenser part.

Very nice HX Jan! My homeroom teacher just came over and was like "what is that thing" and had a weird look :p:
that is very clean jan cant wait to see it go.

Hi Jan,
Is that high silver content braze or silver solder?

It's silver content braze.
Btw. here are the two fans I'll use instead of the current one. They are much smaller and give me room for the hx and phase-seperator.

I think I need new hoses :( This one got killed by high pressure!
The hose is rated for 55 bar WP. At least it is typed on the hose. :(
When the end popped of the pressure was way below 55 bar!

Nice looking Got a drawing of the system? What are the internals of the HX?
Bty the pressure range on teh PEV is 5 to 35 psi. should work for your needs.? If not I can send ya another with different ranges.

Nice jan, but, please, draw and post there HX's diagram :D

get some yellow jacket hoses, their pretty good quality.

03-25-2005, 08:12 AM
Might be pretty hard to find Yellow Jacket in germany:D Those were ITE hoses? I have Refco and ProSet charging hoses and all of them leak from that joint and most of them in the rubber lines too!
That HX looks nice:) I'm pretty sure that I know what that HX has inside.
jan what sorta brazing rods you use. looks different to other brazing i have seen on forums, cleaner.

I have Pro-Set.. damn, I was right with my bad feelings when I was doubting
if buy, or not this hose in A/C shop, this charging hose doesn't look reliable
for me

I know, but I won't tell.. I still don't know how HX does look inside :D

look on ebay theres tons of hoses.

Refco is supposed to be the best quality products there is but still they leaked. The ProSet hoses are IMHO somewhat easier to use since they have rubber o-rings at the fittings and I they seem to be faster to disconnect from the system and with minimum gas leakage. Refco uses teflon in the fittings and it is much more durable material than the rubber so they will outlast the traditional rubber O-rings. Next time I will get some new Refco hoses or maeby make my own from stainles steel;) No leaks then:D

The a-c will be interely inside the ar conditioner case?
If yes,its a really good find and i will try to find some case like that and a big rotary for my next project =D.

A drawing of the AC system? I don't have one.
I'll see if I find pics of the inside of the hx. If not I'll make a simple drawing.
I think the PEV should work fine. If not I'll send you a pm and order another one. :)
@ kayl
the brazing rods contain 40 - 45% silver if I remember corectly!

Yep. I'll put the whole autocascade inside the AC case.

Yikes, 40-45% rods are really expensive, at least here they are. 15% is alot cheaper, you only need 45% for steel to copper.

But dosnt that brazing look some much neater. From my own standpoint, if I'm spending hundreds of $ on a phase change unit whats a few extra bucks on some rods.
Think I'll go for the highest 5 silver rods I can find.

ditto that. Funny how things add up.. I just bought a 485$ yellow jacket vacuum pump because my 1 stage pump blew its motor.

Filling larger gaps with that high content alloy is a real nightmare since it flows so easily.
