My first SS

http://images.people.overclockers.ru/112732.jpg
Compressor - daewoo PL15JLE-5 (200W -15С) Cost ~ 50$ :)
Condenser - 5м Copper Tubbing 6мм.
Freon - R12
Evap - made of diod
Т idle -30С
T load (100W) -12С

Nice :)

I had a kryotech renegade ~4years ago which had coils like yours and i changed them with a condeser. I had i nice boost.

congrats m8. I have a friend of mine who lives here * in Argentina* and I admire myself how he is capable of getting good results from scrap. hope its your case also ;)

Unseen That is only the beginning :)
Duh What do you mean by "scrap"?

looks good mate for a first go im about to start mine after a bit more reading and waiting for a few more bits to come hope it turns out ok for you :).

Im sure he didnt mean it that way dude, my bro said my first unit looked like scrap. He didnt realise id spent the whloe day making it look presentable.:p:

Im sure you will see a improvement with a condensor, id like to know how effective that pipe method is :confused:

Oh and get some tinted Perspex on that case. :)

Budget ghetto unit :)
Good work
You can achieve better temps regasing the unit with some cheap R22/R290

You should try a fan on that coil condenser.

U got a filter/drier on that thing?

I don't see one but if a unit is purged properly and properly vacuumed you shouldnt actually need one.

Not bad for first build, but try to get some condensors ;)

regards

i agree, you'll get better temps for minimal extra cash, just a small condensor and fan

Great build for the first time. Hope mine gets as good as yours.

You should listen to the guys, I think that the condenser price is something like the price of 6M of copper tubing :)

One more quiestion, if you don`t mind. Am I seeing wrong or you didn`t put the cap tube around the suction line ?

Regards,
Sven

EDIT:
@n00b of elite
Thought that subcooling is a good thing here ? Or subcooling is just like superheat, only good at some range ? No OT more, just this...

You dont have to, it only increases the subcooling.

as 4Qman said: of course it was not offensive in any way, congrats as said before.

Hmmmm. Now that looks familiar.

I agree on the condensor note. A proper condensor will give you better results. Or at least a fan on that coil for now.
Not bad for your first build tho.

Good job for your first unit!

Few things I would do though. Some of which have already been mentioned;

1) Add a fan to your coil of pipe, or buy a condenser... it will increase efficiency a lot!

2) A filter/drier would be a good idea (if you haven't already got one) and may reduce the chance of any blockages etc, unless you purged all joints and vacuumed it out (which I doubt people would do in their first unit).

3) Wrap your captube round the suctionline! You can probably gain a LOT :)!

4) Try getting hold of some r290 (or propane), the boiling point is -42c so if you can condense it properly you will see much better temps.

5) I don't think you need quite as many coils on your suctionline before it re-enters the compressor. It might trap oil. I'm not saying it will, but it might just happen, and that's not good lol!


And don't worry about it looking messy, my cascade looks stupid but as long as it works I ain't really bothered :D! A lot of units on here look ghetto but it's the performance that counts. And you're only learning too!

Not bad at all for a first time build, but as everyone else has said, get yourself a condensor. In my experience they have been the hardest part to source but you'll see some serious improvements. R290/R22 will also be a great improvement, R12 is absolutely evil. As NoL said, wrap that capillary tubing around the suction line, you'll see a minor increase in efficiency there. I'm guessing you coiled the suction line to combat the vibrations of a solid-copper suction line, good call there ;) How long and what diameter is your cap tube, adjusting that alone could make a huge difference.

Nice one mate, keep at it as it will pay off in the end, well done on your first unit

The answer to some questions :)

There is no opportunity to fill more powerful gas, the compressor will break :(

PS. Who wants to submit to me condenser PM

How's the high side pressure and temp before the filter?

Has not absolutely understood a question
You want to know pressure upon the side of a high pressure

You will need access port (schrader valves) on high pressure side (between compressor and evaporator) and another on low pressure side (somewhere between exit of evaporator and compressor) You should have a service port on the compressor that will serve as a low pressure port. Using these ports you can connect gauges and read your high and low side pressures.

Nice, clean job :) - it will only get better

runmc Thanks, next time i'll do this.
