Are there any HVAC guys that know about cars a/c? Here is my question.... I am running new lines, reffering to the bigger line going to the condensor, Is it OK if it has a loop in it as apposed to a bend? I am workin in tight space and am trying to keep good flow. Is that more important then possibly creating a dip or valley in the line? The reason I ask, is I am understanding the compressore lube could get trapped in a low spot. I am also thinking about putting the air dryer up by the condensor unstead of the firewall. Any thoughts on that? Lastly I have 2 schrader fitting large and small lines. The illistration doestn depict what position these go. I realize 1 is High side 1 is low side. ANy input on that also would be great. Thanks
I would start, but I don't have it in me at the moment. Extra ****er. And loop is OK, drier is OK, dips in line are ok, Schrader does not matter as to orientation. And it's not an "air drier" Now delete your question like this never happened. Or here http://www.jalopyjournal.com/forum/showthread.php?p=6774473#post6774473
I realize there are poeple out there that give bad answers to cause issue's, Why get the popcorn? I also see badshifter attached my other thread which I couldnt find and thought was delted finally, since for some reason it anded up in the introductions section??? Anyways, as far as the Air dryer goes.... you seemed to know what I was talking about.... An item with many names, air dryer, receiver dryer.... you knew but ha to make a comment. I was hopin for some honest technical help, not bantering. Thanks
This guy's in TX and he's against A/C? It's hot enough here outside to pop pocorn for pete's sake. Get a life... I wouldn't run a loop for the reason you mentioned. Also, I would keep the hard line lengths to a minimum and cover all the joints with insulating tape.
Drier should be close as possible to the condensor...try to keep your lines straight...no loops, etc...shorten it if you need to. I've put A/C/heat in my '55 Cadillac...and cruise control and tilt wheel...don't like it, too bad...!! I do and that's what's important, not your opinion. Go here to see the five year build right here on the HAMB: http://www.jalopyjournal.com/forum/showthread.php?t=329070&highlight=the+best+55+caddy+build R-
The large and small schrieder valves are probably the valves used for R134a..they are different to the old R12 valves.The receiver /drier needs to be close to the condenser.If your lines are too long, get them shortened professionally..do not try to do it yourself under any cir***stance.I don`t know what parts selection you have, but they need to be matched for duty...it`s not just a case of fitting any evaporator with any compressor and condenser....gas charge is crucial.....if you are unsure of your ability to fit and charge the systyem properly and safely, take it to a dedicated shop and get it done properly with a guarantee.I don`t know what laws you have over in America, but you are not allowed by law these days to handle refrigerant without a 2079 certificate.
Thanks for the input everyone. My main issue now is the radiator is so close to the place where it mounts. I can go over the top. or drill 2 big holes. The holes drilled will be under the fenders when I put them on. I will try to post pics, actually the part I am having trouble with is is exactly in the area pictured in my avatar.... I am almost ready to find a shop and pay them. I just want it right.
Why the pop corn? I think you may have jumped the gun a bit without knowing all the facts... The guy didn't say it was going in a Mustang...Read all of his posts. it's going in a 40 GMC. You do have A/C in older rides down there in TX don't you? HellRaiser
It's not an air dryer because there can't be any air in the system. Many newer vehicles have the orifice in the receiver/drier so it is put as close to the evaporator as possible. Anywhere in the liquid line between the condenser and evaporator is fine. If oil would settle in a dip in a line, it would settle in the drier too. While the most direct route is the best, it isn't always possible.
The firewall going into the floor of my '34 is at an angle, or the floor angles up to the firewall, whatever. The evaporator unit is under the dash where the glove box used to be. My drier is mounted on the condensor. My condensor lines come out make 90 degree bends go between the grille & the radiator, of course 1 goes to the compressor the other to the evaporator then the line from the evaporator to the compressor, both long lines lay flat on top of the rt framerail, wrapped with the cloth/foil type insulation to stay away from exhaust & engine heat, behind the inner fender. Then the 2 lines go up thru holes in the angled lower part of the firewall/ floor and lay flat against the inside of the firewall then bend and go to the evaporator. To me this minimizes the visual impact, nothing on the firewall, gets the lines out of the way. Works well too, I have a Vintage air mini setup. From your photo if you have room might run your lines beside the inside of your rt framerail to kind of hide them, if you have the room, of course my 34 is much more cramped. Hope this helps.
K I got it...After all the input, I have come up with making 2 holes in the area under the headlights that will be covered by the fendewrs.... Running the lines off the condensor through those holes and either to the compressor and to the fire wall. I will run them up the frame rail or just try to hide them, as stated very well minimizing the visual impact... I will also make a rectanular box to go over them and paint it black ads it goes through the fender well, that way If the fenders are off it will still be clean looking. I am un sure yet on if I am gonna mount my dryer in the grill or on the fire wall. I just gotta see what looks like what. Thanks again everyone who gave positive input on my A/C installation debacle.......
Could you mount the drier inside the fender behind the 2 holes that you are going to drill? Seems like you should have it as close to the condenser as possible, and this may be a good compromise.
I work strange hours so, I havent been able to update this thread, so here is where I am at.... I got al the lines crimped, that was a job in itself. No one around here does Parker Futura hoses. Hydraulic lines are different, and use different die's. Parker wasnt very helpfull, and reffered me to a guy in Texas who bareley Ablahed..... SO that was out. But a buddy who owns a local repair shop happened to buy the press from a place going out of business, so I got lucky.... Here are some current pics.
I am mounting the dryer on the firewall, and the lines I out through the side are in the wheel well. I am going to cover them with a metal cover for now and the it will all be hidden once the fenders are on....
Call me dumb and stupid and I can usually read around all the spelling misteaks...ehr...uhm ...mistakes HAMBers make, but I certainly cannot figure out the word in RED... R-
I guess you never saw heart break ridge, when Gunny ask if this wa the right place and they responded ( me no ablah) I was in a rush to get out the door earlier so I didnt get the type o's.... I always loved that line.... Yes it looked like he most certainly did Ablah....LoL
Your 40 is a pretty hard core traditional car too, from looking at your profile. fifth 40 ford---302, c4, 9-inch, 4 wheel power disc, fatman ifs, etc.,etc. i grew up in the 50's and cars is what everybody did in our town of 16,000 in Nebraska. Lots of serious traditional stuff on that car. I spent the first eight years I was married living in McGregor and don't remember sweating as being an enjoyable part of driving the 48 after I first built it in 1973 and was less than half the age I am now. We have several long road trips planned for the 48 after it is finished and ac and a good heater/defroster are part of making those trips a lot more enjoyable than past Trips back and forth to Texas in it were.
It is almost ready to charge.... I finished the the wireing under the dash, and also put in the receiver dryer. Now all I have to wire the Binary switch, and it should be ready for charge....... I really dont mind sweating, although it ****s getting all sticky headin to a function, but I have asthma. I need air. Its pretty simple, and I cant imagine not cruisin. I have nuthin to proove....SO for what ever reasons everyone has for their opinions, mine is more medical then anything. Not to mention its my car, if I want to drive it off a cliff, then I can.
It is done and going to a shop at 8 am for chargeing.... I want to share my experience with Southern Air Hot Rods, simply put.... A great group of people. Very helpful, and they stand behind their products. I have there Super Frost system, and it moves alot of air. I also want to thank HellRaiser for his tech info and everyone else who helped.
