RULES

There are two classes -

1st class - "CO2 Division" - first stage gas builders choice, second stage gas CO2

2nd class - "Open Class" - first and second stage gases are builders choice

All parts are homemade except for metering devices and evaporators.
All compressors will be 1hp or smaller for both classes.
All AutoCascades will have a high pressure cutoff switch.
PEV's, TXV's, EEV's etc can be used.
There are no condenser limitations.

If there are builders who want to build an AutoCascade that is larger than 1hp , we will set them up their own special class. "Super Pro" I think it is only fair to let people have a choice to go all out and use what they want. This class is for them. We don't want to miss out on anything.

You MUST use high pressure cut-off

FINISH DATE: 01.09.2006

Post your comments here, maybe you have some suggestions ? This all is for fun, so join to this competition

[piotres]

Judges: Maybe Chilly1 or Runmc ?

Chilly1, Runmc ...

Rules I think will be that same like in previous competition, so:

"The rules so far:

-Compressors up to 1hp, all types count in. 2 stage compressing does not count in. Only 1 compressor can be used.

Agree

-R290/R22/R404A/R507/R134A for I stage refrigerant, CO2 as II

Free choose for I stage refrigerant, R744/R1150/R508/R503/R23/R13 (maybe R410a) as II

-All the parts must be DIY, commercial oil separators, liquid separators, HX'es can not be used. The only commercial parts that can be used are safety devices as: expansion tanks, cut off swiches etc.

Why not only DIY expansion tanks ?

-only DIY evaporators can be used. Copys of commercial evaporators are allowed

Can be done on CNC Mill ?

-PEV's, TXV's, EEV's etc can be used.

-there are no condenser limitations as longas the ambient temps are above 20C" --> by Berkut

Post your comments here, maybe you have some suggestions ?

Mine are in bold

Time to end all builds- 31.12.2006

[LukeXE]

So...

as Berkut said, that CO2 is very common gas, so it`s easy to use it...but maybe you`re right, and we should use other gasses ?

DIY Expansion Tanks, I agree.

[Gray Mole]

I'm in

Likely spec...

3/4HP Rotary
TEV/Captube
R290/CO2


Will see if the rules allow for R23, and may use that instead.

Cheers

Gray

[LukeXE]

Welcome Gray Mole

Please all to write your spec

[Jort]

Allright this is fun!!!!!

mhh put me up the list !!

specs i don't know yet, need to think about some.

c'mon jurgen(aka unknown road) we need to do this.

good luck everyone

[Unknown_road]

how about making the use of a high pressure cut-off obligated? change of something going wrong with these things is probably bigger as with normal cascades.

@jort: I don't think I'll join. I'm already building an autocascade and it isn't going to run on co2

[Jort]

agreed

[Gray Mole]

Yes, I agree. Minimal safety for the competition should be a HP cutoff. Promote safe practice

Cheers

Gray

[runmc]

It's a great idea for some friendly fun. You will need a finish date.

[fatty]

Ok I may be in not built and auto yet

[piotres]

I don't know my specs now ...but the most possible :

Sanyo C-1RV137H11AA rotary (I think it's 3/4 HP)
Captube/Captube
R507 or R290/Co2 or R410a or R1150

[n00b 0f l337]

What about r22 for first stage?
If so, I'm in just for fun.

Rechi 161 Rotary Compressor ~1/2hp
R22/co2 (i'll get a paintball tank)
Captube/Captube

[LukeXE]

So, we all will use high pressure cut off, and max compressor power will be 1HP or less ?

Yes, what`s about time to end all the units...Maybe to 01.09.2006...it`s 5 months, it`s much time to build auto-k. What do you think about this date ?

[n00b 0f l337]

Sounds good, definetly a long time though.
Where can you purchase high pressure cut offs>

[LukeXE]

Really, I don`t know

So, we will leave CO2 as ONLY II stage refrigerant ?

[n00b 0f l337]

Yes, any thing else is unfair.

[LukeXE]

Yes, any thing else is unfair.

Yes, it will be less dangerous than r1150 too.

[muciek]

And me!

Aspera 12,3ccm 1/2HP, captube/captube, r290/r507/co2

[n00b 0f l337]

People should list there displacements.

Mine is 9.8cc

[Gray Mole]

lol I have no clue what the displacement on mine is.

I'll try to find out though.

If I end up using one of these 2 as I plan to, it's a Mitsubishi Electric 3/4HP R22 Rotary.

never could get all that much info on it tho :p


Gray

[n00b 0f l337]

Heh I'll lose on HP and displacement at this rate.
I'll probably attempt two with matching specs but charge and play with them diferently.

[runmc]

Okay , I talked with Chilly1 on the phone and he thinks this is a good idea. Discuss it between yourselves on the exact rules and submit the list which we will follow.

[cold_ice]

I think it's better when all gasses are allowed. Only CO2 is not good in my opinion, I won't use it
I will use a LG GK151P Rotary, it has ~12000 btu/h, so it should be 1HP. And captube. I don't know which gas yet.

[n00b 0f l337]

Its not fair to allow anything else cold_ice. I have no 2 stage gases atm and neither do a lot of others. If we all had ethylene that's what we'd use, but co2 is the current DIY.
Why not make classes based on HP of compressors?
