2000W Chiller

[Sidewinder]

Yeha, im back again
Maybe some of you still know me, well... i hope so...



Well, i just started to build a Chiller, well, its not my first, but the first i will publish.
The Project was thought to be just for one Forum (fastgen, maybe some germans here know), but sky meant i should post it, well here we go.

The Hardware:
L`Unite CAJ2446Z
CEV 4130 (Condenser)
Selfmade Pipeheatexchanger (oh dear, my english...)
Filterdriers, 10mm for the liquidline and 12 for the suctionline
Bitzer FS36 Accumulator
Alco Pulsmod. Expansionsvalve EX2

I think i got all the other stuff at home...


Most of the stuff, condenser, driers, PMEV, compressor, accumulator...
It's no Bitzer, they didn't had one and i didn't wanted to waste time, so i took this one, it has 4cm³ more then the Bitzer and it does not have thoose glasses (name?).


Screwdriverwork! \o/
Haha, well... this was fun... i need a electric one again.


done.


phear my new skateboard


Condenser is up, screwdrivertime again \o/


Bit later, at 8PM i stopped because i wasn't in the mood to continue... tomorow comes a new day


and the other side


Ahye, and the PMEV, cool thing

[jellybeard999]

WOW...

what temps are you expecting ??

im assuming 2000w just allows you to cool more... and not neccesarily getting it colder than a 200w chiller...

[Sidewinder]

Well, i'm not expecting extremely low temps, i just want to cool a few computers and my beer

[Dissolved]

Well i hope your Electricity Bills wont bite you too hard.

[Sidewinder]

hehe, yeah, im lookin for somethin like a flatrate for the electricity, i really need one

[_HL4E_HalfLife_]

I hope u have a 220v heavy duty outlet there! A compressor of that size isn't gonna run on 115v and will draw in upwards of 10amps or so depending on its load.

[expansionvalve]

I could freeze a few pallets of ice cream with that compressor lol

[saratoga]

Are you sure its 2000w? Google says its a 1.25HP compressor, and the specs say it maxes out at 1100w.

Either way, its a beast.

[expansionvalve]

I think it's 3/4hp looking in a book,
Evap temp-40C Duty in watts270w
-35C>498w
-30C>754w,
-23C>1106w,
-20C>1305w
-15C>1645w
-10C>2060w.

Can I see some bigger pictures of your brazes?

thats what i meant, ~2000W@-10°C

Can I see some bigger pictures of your brazes?

uhm, sure, why?
btw, beware, they're ugly, didn't brazed for a long time.

[craig588]

I think he wants to be sure you won't waste any gas because of very small leaks.

[Stewie007]

Well, I seem to see alot of these bubbly looking brazes that the novices do. Bubbly brazes usually mean a weak joint. It does not denote a successful braze.

I thought I was seeing the signs, but without a closeup theres really no way of telling.

[Stewie007]

Basically, you want them to look like that.

[expansionvalve]

I can see red X

Well, no, they're allright, i just wasted to much braze on every joint... need some practice again :/
btw. i'm no more novice, just a bit out of practice.

[Jonny]

did you already braze the "pipeheatexchanger"?

Up to now this beast is looking awesome

[Sidewinder]

lol, damn i hate the word...
no, i'll start tomorow.

[Tonic]

Stawie, what are those pipes? Large heat pump?

Sidewinder, long time no see someone who made really nice unit (placing parts and
pipe bending) Buuut, you forgot aboud U-bend on discharge line!

[Sidewinder]

Looks like an industrial Chiller, as far as i know his job is to build thoose units.

Thanks, well, I'm a 100% perfectionist, lol, that doesn't make things easier
Well, why do you mean I should make a U-bend on the discharge line?

@topic: I did not had that much time on the weekend, I just made it to connect the drier to the accumulator, nothing special here...

[Stewie007]

It belongs to this. Low Tonage (40 Ton) Industrial Water Chiller.

[Sidewinder]

very nice, semi-hermetic compressor, plateheatexchanger...
hm, damn, that hx is huge, how many Watts has it?

[Master_G]

phear my new skateboard

Phear your socks and sandals combo as well!
Seriously i pity your hands without an electric screwdriver for that lot, doesnt look very fun.
Nice project, look forward to more pics and results.

That particular unit is rated at 40 Tons. You can convert that to Watts or BTUs if you want.

Given that 1 Ton = 12000 BTUs, then This Unit has a total Capacity of 480,000 BTU/hr Capacity

1 BTU/hr = .293 Watts, so 480,000 BTU/hr = 140640 Watts Capacity

What is the chilled water being used in?
