A/C Reverse The Gases in Early Model 911's

Agreed - look at the absolutely horrible results that my technologically obsolete a/c components provide! And obviously, my serpentine fender condenser has its limited effectiveness cooked out of it by the exhaust! Shame on those who designed, sell, install, buy and use these garbage products! I guess I should just throw all of my system upgrades away and start over!


This photo was taken on a 98 degree day, car idling in my garage (1K RPM idle speed), high side pressure of 210psi and lowside of 30psi, max fan and thermostat settings, no evaporator freezing even after extended operation.




This was taken on an 86 degree day - car idling in garage immediately following being used for errands (combined highway and city driving, moderate traffic, and at least two times parked in store parking lots - aka: heat soak).

I am sensing an endless looping stream of the same message from OP.

The point has been made but remains unverified.

Is there any sense/value in this thread continuing?

Perhaps for the comedic value?!?!

Ronnie, can you describe your system and components?
Thanks!

What a load of BS!!!

Zippy, I typed a fast-n-dirty description of my system in post #61 of this thread, but can write it up in more detail if you like - let me know.

What's "BS" about it? Are you suggesting that I am falsifying information for the sake of one-upping you? If so, I assure you that is not the case (even though I did one-up you - again). I live in an extremely hot and humid climate, but am a polar bear at heart, and I primarily work outdoors in the heat . . . in other words, a/c is extremely important to me (both home and auto a/c), and would not lie about results for sport, rather, I would post up asking for help if I was not getting the results I wanted.

Ronnie,

Maybe he's calling BS to your statement "no evaporator freeze up even after an extended period".

At the sub-freezing level of the guage you picture the Rh would have to be practically ZERO for that to happen.

Someone correct me if I'm wrong but it seems to me you need a rewrite of the laws of physics to have that happen.

That's the base problem with using a CCOT charging procedure with a TXV system, the TXV doesn't have enough range to compensate for such a low refrigerant charge so you must rely on clutch cycling(***) to prevent evaporator freeze up.

*** Cycle the compressor clutch off a few degrees above freezing and back on a few degrees above that. Remember that the liquid refrigerant stored in the R/D will result in "coast" period of cooling even after the clutch is cycled off.

I NEVER wish to see myself siding with KeloGes on any matter, but...

[Ronnie's.930]

Will, I can't explain why I don't have problems with evaporator freezup, but I don't, and if I did, I would post asking for assistance.

I have "tested" my current setup in many varying driving conditions, including 70+ mile highway drives after dark in the summer when the temps are still in the mid to upper 90s and the humidity is very high, and have not experienced evaporator freezing. Of course, when the sun is down, and with a system capable of churning out such cold air, I do not need to run the thermostat on max even to meet my "unique" comfort needs, so perhaps if I did, the evaporator would eventually ice? But that is not what I call a "real world" operational situation for me - not a concern of mine, in other words.

Ron, Ron, Ron....you just don't want to listen to me anyone. I told you many times that you could increase your luke warm AC temps with one simple step. I will repeat it for you again. Reverse your front and rear windows and you will ALWAYS have cold air blowing in. But,NO! you never listen to me so.....I am not going to tell you my secret weapon again. I have had it with you and that goes for your weenie buddy Bob, or Bud or whatever his name is. I would post pictures of my ingenious method but, unfortunately I sold my car.

[DaveMcKenz]

Hi Ronnie,
Could it be that your humidity is too low to create ice and freeze the evap? I don't know your climate. Also, high evap blower speed will help prevent freeze up.

YOUR TEMPERATURES AND PRESSURES and YOUR TESTS YOU CLAIM ON YOUR 911 ARE A BS LIE!

AND/OR

You have a special deal with GOD only you have ON THIS WORLD

roflmao

[Oh Haha]

Looks like Ronnie is getting pretty darn cold temps at the vent seeing as how the thermometer has frost on it!









Disclaimer: I don't have A/C on my 911 as it was ordered without it.

Ronnie, you are just a stinky old can of corn from 1986 that fell behind the rack at the grocery store.


BTW?

If you are roflmao how can you type?

[Ronnie's.930]

Zippy - got it and will get back to you.

Gary - you Sir, are neither a scholar nor a gentleman and are deserving of about twenty !!!

Dave - extremely humid in North Texas year round (though not what Karl faces in Miami FL) - I usually have my fan speed on high, so maybe that helps explain things. I like the air movement then, and the noise doesn't bother me because I can't hear it over the engine/exhaust or the blaring Slipknot.

Reid - I would expect nothing less from someone who does not have the results to back up his chest beating - good job representing your "types".

Bob - yo' mama!

Wayne - that's not frost, but dandruff from Bob when he used the thermometer to take is own errrrr, ummmmm "temperatur" . . . I soaked my hands in peroxide immediately following that pic!

[KelogGes]

Dave I posted 911 Diagrams for you to help you visualize what Porsche did wrong
and is still being done wrong by others

This should help you figure out REVERSING THE GASES and understand better

You deserve a box of Girl Scout Thin Mints for your contribution. I am serious, bro. An entire box.

Now can somebody shut this pathetic thread down.

I swear to God, I will make it my life's work to oust you. You are an embarrassment to the thinking man.

Edit: You got nothing. You are the liar.

Normally a high A/C blower speed would prevent the evaporator core from declining to sub-freezing levels, especially in our cars. Additionally, the blower flow direction is in opposition to the gravity flow of the condensate down and out the drain. Even worse, the system is always in recirculate, so any moisture contributed via human metabolism just grows and grows.

The only way I can see for preventing condensate accumulation in the cabin is to provide fresh inlet airflow, blower forced or forward speed, HOT/HUMID fresh inlet airflow.

Ronnie did install a monstro evap blower last year. Took him a couple of weeks to craft. Not sure if the pics were before or after this addition.
