Time to turn theory into practice

[pythagoras]

Time to build one of these phase-change thingys

Scary times Ahead as my practical skills are screwing two bits of wood together :rolleyes: . Although am sure I'll get lots of help here. ;)

Below (or above depending on whether attachments go first) is the kit that has currently arrived. Thanks for the block and extras Chilly1 :toast: . Kit bought but not recieved:

That bernzomatic torch looks like a cutting torch to me, you might want to find a map gas torch. I don't see any suction lines in your pictures. Hope it all goes well for you, looks like you spent well over 1G on tools and parts.

[pythagoras]

Hi gkiing,

The torch is meant to be adjustable so that it will cut/weld or braze. Mapp bottle is a good idea, I could use the propane to charge the system with then so its wont be wasted.

As for cost its upto £518.59 :( That includes the items I havent recieved yet). And that includes the two compressors, which are new and unsealed. So seems reasonable

Side note, we blew up several brand new Aspera compressors R404/R507. It should be ok with R22.

They do not like head pressure and fail too easily.

Makes me feel better about only paying £10 for it now :rolleyes:

Thanks for the warning Fugger.

Compressors arrived today :slobber: You get no idea of scale from pics on this forum, they are huge.

R22 aspera is 1/2 HP.

I need some help identifying specs on the Techumseh its number is AKA4476yxc, I think thats 7600 btu, but not sure, anyone know the full specs including the HP?

When you get new and sealed compressors do they already have the oil in?

If I have read the P/T charts correctly I only lose 6C using r22 against r507. R22 cost me £25 inc cyclinder of 13KG where as R507 would be over £100 for 11kg. Why is R22 so much cheaper?

Yepp, compressors usually come with oil in them :).

I think i've heard that R22 is cheaper because it's easier/simpler to make. Could be wrong about this though.

[gkiing]

yeah, its usually the manufacturing costs that make it so pricy. R22 is about 80$cdn for a 20lb cylinder here.

[pythagoras]

Thanks,

Theres something wrong with my calculations on the techmseh compressor :rolleyes:

I have btux0.293=watts and wattsx0.00133=hp.

Now if this is 7600 btu's I get 7600x0.293=2226.8watts and

2226.8x0.00133=2.96HP that cant be right!!! What am I doing wrong here?

Regards

John.

[gkiing]

1HP is about 760W. I think that 7600btu/hr is around 1.5hp, you can use google to convert btu/hr to watt. Type convert 7600btu/hr to watt and it will give you an answer.

[hatemi]

Someone posted a link to a very nice converter program ih here some time ago. I have the program and can send it to you with MSN or a-mail if you want.

[100]

pythag, where did you buy for compressors for, and for how much?

[pythagoras]

Thanks hatemi, I'll pm you my mail address.

100, those two compressors where a real bargain from ebay £25 for the pair.

Regards

John.

[Pandrone]

Hatemi, i think you mean Convert, that program is very usefull :).

Anyway, here you have a link to it at Danfoss.se
http://se.refrignet.danfoss.com/SW/SERA_Unit_Conversion/sv/index.htm


That can't be right, i have a 14000btu rotarycompressor, tried converting 14000btu/hr to watts and got the answer 4099watt, that would be like a 5HP compressor, so are you guys sure this way of counting is right?

[pythagoras]

I know where we're going wrong here, you cant convert the cooling power into HP. You need the electrical wattage of the compressor to convert to HP :rolleyes:

John.

Yepp, you nailed it there :). The 14000btu rotary i have has 1395W(220v) 1420W (240v) motorinput, umm, dang that's almost 2hp anyway :D(if 760w is one horsepower).

[pythagoras]

This techmseh is 870watts so 870x0.00133=1.157HP.

The cylinder of R22 arrived today, it has 1/4" sae charge port and two hand valves. One says vapour the other says liquid. I'm assuming the liquid hand valve is connected to a dip tube that exits near the bottom of the cylinder.

Is there any advantage to liquid or vapour charging with R22?

Regards

John.

[PMM]

pythagoras take it your in UK? I also bidded and won sim items from that
same person though I'd wish I'd waited a bit longer as he dropped prices
on them since plus he's a bit dodgy as he charge sep delivery on everthing
even if you offer to collect.

If you are UK who you using as your source for gases? be a while before
I get around to anything need to sort meself out some training courses 1st.

[pythagoras]

Hi pmm,

I am in the uk, pm me the guy you think is dodgy, not sure who you mean ;)

I use Rabtherm for gases, free delivery and very cheap( If you wait till he has a van in your area). What area of the Uk are you from? One other thing about Rabtherm, they take cheque on delivery, so you wont get stung ;)

R22 is pure gas so you could vapor or liquid charge it, the only advantage liquidcharging that i can come up with it that it doesnt take that much time :).

R507 £8.50 Per Kg in 11.3kgs Disposable cylinders = £96.05

96.05 £ is that the price of a 11.3kg R507 bottle(with gas)? Nothing more?

I would say that's cheap :).

[pythagoras]

Yes thats the total price, but of course in the uk we also have to pay tax on top of that at 17.5% :mad:

Okey, but that would end up at around 112£ for a bottle of R507. I must admit that i haven't seen anyplace in sweden sell it that cheap. This is one of the times i wish i lived in the UK :D.

Wonder if importing is an option :D.

[PMM]

thx pythagoras :)

[froudeg]

Hi pythag,

Did you say you got a condensor? - if not www.hawco-refrigeration.co.uk do some nice ones for a reasonable price...if you need their full catalogue pm me (i got it in pdf form).

I just bought a load of kit from their for the compact cascade im building - some dryers, condensor, liquid receiver, sight glass, fittings etc.

As for suction line hoses, i have yet to find somewhere in the UK that sells the corrugated stainless steel type - on the my old prommy that i repaired, i ended up using supahoze (teflon, braided type) - it's been fine, but as other people will point out, they don't trust them. I certainly will need something better for -90c ethane temps. Let me know if you manage to find somewhere that sells the corrugated stainless steel types....i know BES sell some really thick 3/4" ones, of which i bought one, but it is as thick as a tree trunk lol

[pythagoras]

Hi Froudeg,

Will keep you informed if I find any nice suppliers. Maybe its getting time to form a uk phase change club :D

Thats depende upon the compressors effeciency at that tremperature if it has a watt cooling to watt motor of 1.3 to 1 or 2 to 1 the hp will be differant. You need to know the full specs. usually R22 compressors of 1 hp are 12,000 btu so the 7700 btu compressor would be 2/3 hp but may be considered a 1/2+ hp.

[Pandrone]

Btw, do you have a pic of the R22 cylinder? :)

[gkiing]

r22 is meant to be gas charged, not liquid charged. Did you buy an 11kg cylinder? The one I got doesnt have a liquid line, only gas.

[Blergo]

i stumbled accross rabtherm before but as i live on the west coast in wales delivery would be a problem i reacon. Havent managed to find any local suppliers though which kind of sucks, im stuck with bbq propane and reclaimed R12 atm.. lol. a club seems like a good idea though :) we should start a UK phase change club and set up a website with all our projects and stuff on it, i dont mind hosting the site either aslong as someone else does the HTML..
owen

[pythagoras]

Pandrone any particular angle you want for the r22 cyclinder shot, is it the valves on top?

Gkiing, its a 13kg cylinder.

Blergo, I live in Wigan, just north of Manchester an got free delivery, so I guess its worth a shot. They tend to get a few orders for your general vacinity and then send a van out.

Regards

John.

[Blergo]

ah well, i spose i can try :) or get it delivered to my mates house in london and get her to bring it up when she comes to visit me around christmas time. im sure it's possible. i must say i'd love to get my hands on some R22. lol. my waterchiller has an R22 compressor but is useing R12 atm, i was going to regas it with propane but i think i might wait and try and get some R22 :)

HI John : Enjoy your vacation :toast: I noticed one other thing missing, A "calculator". While refrigerations calculations can be quite complex,They are essential in designing a system.If it dosen't work on paper,it won't work in pipe! I just wanted to throw that thought out there for guys new to refrigeration too think about.Calculations for load,loss,effiency,ect.,ect.,ect.,Getting all those right is the true intellectual challenge.If you get all that right building a system will be a walk in the park.Take lots of pic's,everybody love's pic's. I was going too say good luck!but it's all in the planning. Good luck anyway John ;)

[kayl]

quicker
sigle stages only take about 5sec of liquid charge.
by liquid filling, the evap should freeze just filling letting ya know the capillary line isnt blocked. :toast:
then low side fill when when system on.
Also the sound of liquid refrigerant squirting into the system sound sweet.

r22 is so cheap casuse its gonna be band soon everywhere.
ya got a lot of toys there

[chilly1]

There is a little thing called COP (coefficient of performance) with compressors HP is loosley associated to cooling capacity is a 12,000 btu per HP so I would but that at about 2/3 Hp...

[bxa121]

im having difficulty locating compressors... any of you guys have any online places for getting compressors???
pm me please (as i dont wanna trash up this thread)

thx

[pythagoras]

Well I'm down a few hundred dollars now :mad: The guy pmm was refering to ripped me off to the tune of $350 for refrigeration tools :( . And to top that a gang of 10 thugs walked down the street I live on knocking off the wing mirrors so thats another $360 I'm out of pocket.

Not to worry I'll press on.

The plan given my limited budget now is:

1. Two stage classic cascade(It will have to have R22 in both stages for the time being.

2. Work out load calculations for gpu and cpu.

3. Decide on metering devices for dual evaps and interstage HX.

4. Calculate length of interstage HX. Tube in tube.

5. Calculate heat capacity of the two condensors I have. One will act as a desuperheater for low stage.

I have loaded watts as x800xt pe 65w loaded. p42.8 prescott@4.8 150 wats so a total of 751 btus.

I want to design the system to have ethane in the low stage, so will base my calculations on that.

I can only think of cap tube or cpev for the evaps, and I would rather go for cpevs so that when I get some ethane its easier to retune.

HX length, most of the research papers I have seen have the interstage HX at 12m or over 36'. Most people around here seem to stick to 15', any reasons for that?

Open to any and all help here. I will have a working system in 3 weeks come hell or high water :D

And i have been charged £192.69. WTF! :mad:

Anyone know where i stand with this? The going rate for this compressor does seem to be about £190 but since they originally displayed and then confirmed the order as £49.99 are they forced to stick to that?

I really want to know what to do.

You guys...its not that hard. Although i never tested this HX.....

13ft of 1/4" inside 1/2" inch. The 1/2" as you can see did start to flatten out some, but its not bad.

You could braze the seam's together for a better heat transfer if ya wanted too also.

lol man that's hilarious.

The best way i've found. Is when you buy it, keep it in the "raw" circled up form. Take the circles 1/4" and insert it into the circled 1/2" and it will go in so easy. I did it like you did the 1st time and it took forever and pinched the hell out of my palms. Did it by leaving it coild and it took me 5 min.

[pythagoras]

And you tell me this now :slap: :D

[gclg2000]

oh the in case ya need it. Circumfrance is Pi*r*2 //// C = (3.14159)(radius)(2) or C = (3.14159)(Diameter) //// use those to find total length so you don't have to uncoil it, bend it all up to measure it which is what made it really hard to shove in.

Now squish it together and braze the seam's together for that extra bit of transfer.

I'm pretty sure He can do the math:D

Those are some large diameter hoses you have there. You plan on having a lot of capacity with this thing, don't you?

Its going to need a lot of capacity with dual evaps. The hose for the gpu is 3/8" and the cpu hose is 1/2".

Don't you guys have refrigeration wholesale stores in UK ? Do you have to order everything? You :stick: need to find a good supplier nearby that has all that little stuff in stock!

[Cossey]

i have ordered my compressor from here (http://www.coolfreeze.com/mail-order/itmidx3.htm) but am not really very happy with the company.

They advertised the compressor on their site for £49.99 as you can see here (http://www.coolfreeze.com/mail-order/itm00068.htm) and i got a confirmation e-mail that says;



All good and well so far. Then a while later i ger an e-mail saying;



And i have been charged £192.69. WTF! :mad:

Anyone know where i stand with this? The going rate for this compressor does seem to be about £190 but since they originally displayed and then confirmed the order as £49.99 are they forced to stick to that?

I really want to know what to do.

Please PM me so as not to spam this thread


im in the same boat with coolfreeze, i cant contact them as the phone no isnt working anmd they never reply to emails, ive contacted worldpay and im waiting to see if they can contact them before i go to the bank to get it reversed.

Here in the UK it seems you have to be in the trade if you want to buy from wholesalers. Makes it a bit more difficult to get stuff, especially if you are a student like me :p:

[wdrzal]

20 years ago thats the way it was here in the states,now everything is so competative everyone sells to anybody.

[Cossey]

Russell_hq how hard is it to setup a trade account? would it work if a few ppl in the uk setup a dummy company then each of us order through them?

Actually you can't get refrigerant unless you are certified and most of the supply houses here in Nevadwa wont well to you at wholesale there are retail stores for refrigeration Like Johnstones and United.

Be sides the required cert. for refrigerants, many places like the ones you mentioned would only sell to trade accounts 20 years ago.since that was one step removed from the public I consider that wholesale. Since the DIY explosion and places like lowes and home depot selling to the public,places that only sold to the trades now sell to anyone who comes in the door with $ ,excluding refrigerants. While the DIY store don't sell the specialized parts for refrigeration,they hurt the protected wholesale business.Sometimes I can buy cans of refrigerant from sams club (walmart club store)cheaper than one the the speclized suppliers.

Hey, pythagoras i have that same torch you have you can use it with propane/oxy or mapp/oxy, when using it with mapp/oxy it gets within 200 degrees of an oxy/acy torch it is a good replacement with slightly less danger. The one probelm i have is the torch uses so much darn oxygen, i went through 6 of those small tanks of oxygen already, has anyone come up with a way to attach a bigger tank of oxygen?

[cold_ice]

It should be no problem to use a 10l oxygen bottle with this torch. You only need the bottle with a pressure reducer.
When I started with phase change I had one of those small torches (other company though), I attached a 10l bottle to it.

cut the hose and attach it too the regulator of your big ass oxy tank :cool:

[total_assault]

ok sounds good, now to track down a place where i can get this 10 liter tanks and regulator, they don't sell them at home depot or lowes

[wdrzal]

I've seen whole(generic brand) acetylene/oxygen brazing and cutting outfits with tanks and carrier at DIY stores for a around $200.00. you get a mc acetylene tank 10 cubic foot and a R oxygen tank 20 cubic foot.This is the size tanks we use on job sites.

[total_assault]

yes, ive sen those kits for approx $300, but i think you still need to get them filled... I would only want the oxygen tank and regulator, since acy. is too much of a worry/hassle and mapp/oxy or propane/oxy work well enough for copper...

[gclg2000]

how is it a hassle? Go get it filled at a welding shop.

[wdrzal]

mapp is basicly propane and acet. the disposable cylenders is what eat up the buget. with welding and cutting outfit you can do about anything.

[gclg2000]

Ya, i don't know about ya'll. BUt i pay $18 to fill up a 120cfm oxy tank and 40cfm act tank. $18 for both. Haven't been back to fill up yet, but i wonder if they charged me right the first time??

What do you guys pay?

[gkiing]

What do you guys pay?

WOW! Here it is $35 (CDN ~28 usd) for an MC tank (10cf) of acetylene and about $40 cdn for a "R" (20CF) oxygen tank.

[wdrzal]

compare this 36.00 per gclg for 120cu oxygen and 40 acetylene

I pay about 16.00 for 20cu r-tank and 10u-mc tank about 1/5 the gas, but its small enough to be easily portable.you pay a premium for small tanks. there is a fill charge plus gas charge.the fill charge is the same no matter what size tank.

I just seen today 8.43 each for those small 14 oz bottles so thats about 17.00 dollars, not sure how many cu foot those have in them.

the bigger the bottle ,the cheaper :for the hobbiestwho wants the best, the r and mc is the way to go. you can get tanks and torches for $200.00 to $300.00

[gclg2000]

This is me below. Sorry about the mess.

http://www.namike.com/albums/album02/Mvc_006f.jpg

[wdrzal]

Are you trying to kill yourself GCLG2000 ? you never ,never :nono: put a regulator on a tank unless it is either secured in a dolly or to the wall! those nylon straps work great. one slight pull on the hose and over they go. did you ever see a valve get knocked of a tank ? there just like a 100# rocket. F- for safty. walt

don't forget to use flashack arrestors too !!!

also high pressure tanks like oxygen, nitrogen,argon,ect should always have the screw on valve protectors on when transporting.

those $20.00 dollys work oK , then they are easy to more if you need to.

[gkiing]

yikes, chain those tanks to the wall!! That's what I like about the portable torches, they come in a nice tote so you can carry them around.

[gclg2000]

cool stuff. Myabe its to pull a vaccum on the charging hose before you open up the tank of freon to charge. That way the entire set is pulled down.

[wdrzal]

it can be used for a varity of things ,I don"t thik its there for a single reason.on your set its used to connect the other end of the yellow hose when manifold is not in use and when in use,like gclg said or you can hook your purge gas there or a micron gauge or the vacuum pump. some cases will require you to use a hose with a valve depressor.

ps how your system comming along?

[pythagoras]

Its an anti blowback device????? Vac hose goes to bottom valve and charge hose goes to the other. So yes would work like Gcgl says.

Why would it be called an antiblowback device?

Regards

John.

system is moving slowly got a weeks vacation in 2 weeks so should see some movement again then.

[wdrzal]

anti-blowback device is the hoses that have check valves in the ends so refrigerant can't be released when they are removed. maybe this is being called that so you can remove the freon that is trapped in the manifold by seal-rite hoses. here in the usa the hoses must have check valves in them.

yes the yellow hose goes to the bottom valve but when not using the manifold you loop it and connect it there to keep the dirt out of the end of the hose,unless there is another storage stud on back like the ones you have on the sides for the red and blue hoses.

Hi,

@JSU those are eaton valves. Sidewinder, yes I got that set of guages on ebay, I havent seen any for a few weeks though, but the guy I bought them from has a couple on ebay.com, he shipped them from the states:

http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=66998&item=7529745563&rd=1

They where cheaper when I bought them :( I paid £40 and £15 for shipping.
