u better

but sry guys ur gunna have to wait a bit. now that school is starting all my consintration is moving over there, as well as money, plus i need to pay someone back. so this project will be back on track in about 2-4 weeks sry for the delay but school comes first.

i got some bad news. after getting it all together before i tested it i started to smell something, after close inspection i notice what looks like a small crack on the suction line. looks like i got alot more work ahead of me. but now i need to look for a vacuum pump as well as a place to buy the refregerents. anyone know of a place? i know it would be easier to just buy another A/C but doing it this way gives me a bit more exp. in this field as well paves the way to me make units for people.

I think you might be able to use Propane(R290) which is quite easy to get your hands on or R134a from a car shop.

thanks for the help, right now i am looking into changing the compressor to a danfoss nf10fx and charging it with r404, i am also looking into changing the cap tube for a TXV so pull down is quicker as well as temps being more stable. but yet i am still looking into it and reading as much as i can before doing anything. like in my past threads leading up to this, i was told to READ AS MUCH AS POSSIBLE. but with school starting today i please ask for your patients till i get settled, then i can continue this mad science project of mine

I'm still gonna have to come check this out. Maybe sunday, after I get back from the LAN (your still invited...).

knightwolf6543,

If your going to do all of that work you can make it alot more efficient. There is a post on Xtreme Systems from Lloyd where he started building this custom for a few models. Let me track it down for yea. He has the specs for it also.

here is one

well after a long talk from a guy over at the Xs forums. i am doing a ground up build.
still designing the system but what i have so far it will have a trombone Hx, TXV and will be charged with r-22, the current a/c will be finished but is to big and power hungry for me to run it 24/7 so it will just be a bencher

That is the same reason i never used mine, There are a few guys on XS that really striped them down to the size of a promie and there really nice. Cant wait to see it

i made another change to the gas, since i spent most of my weekend looking for a r22 rated compressor, and had no luck i desided to go with r134a, i can live with load temps at -10
parts list so far:
1/4 HP R134 Compressor 115V/60Hz 3175 BTU low temp compressor
SPORLAN 1/4 ton EE TXV
Trombone Hx

i'm still looking into a condensor.

also other things i need to get started:
Vacuum pump
Tank of r134a
brazing torch
flux copper rods.

thats all i can think of right now.

 

[knightwolf6543]

i got a few items today ^_^

nah i just happen to have a bunny sitting in my lap (pic posted earlyer) when i started this thread, but if u go to the first post i changed the name

condenser came in today!


next is either going to be the compressor or the HX

 

[knightwolf6543]

sry for my lack of updates.
i cleared myself a workspace in the garage on my dads "temporary workbench" now my workbench , also complete tore down the original chiller. got the filter/dryer, and misc other items. also got a 10 plate HX off eBay that should be coming in sometime this week, still waiting for one of my rc cars to sell on eBay so i can get the compressor and vacuum pump.

 

[knightwolf6543]

HX came in today! its 10 plates

 

[Vaio]

I dunno what that does, BUT I LIKE IT!!


BTW, nice spur gear

heat exchangers put hot and cold liquid/gas in contact with eachother without mixing them. obviously heat gets drawn from the hot fluid into the cold fluid.
