wwest the clueless wonder of the fan mentality that knows nothing about gases and heat exchange
|
I also used to think wwest was the most clueless wonder of AC theory. But now KelogGes and your idiotic and evasive posts have easily achieved the number one position, and by comparison, wwest is actually making some sense.

Algernon glad he is making sense TO YOU!
ROFLMAO |

Your PFC itself has a sound logic basis but you have now wandered to far afield. What your PFC idea needed was to be coupled with some type of additional cooling airflow, which only now you seem to be ready to address. The CFM rating of that Spal blower is meaningless with the existing restrictions both on the inflow side and the outflow. |
Hi Wwest,
I agree with you about airflow, as you know. I looked at the design of Reid's front cooling shroud. I see the small holes, and I was confused. The holes may be an attempt to get airflow over the whole surface of his front condenser. They may be like the multiple holes on a shower head. He gives up some total flow for uniform air distribution. I am not sure, but that may be his thought. Dave |

PS- that cluepon is hilarious, but I think ol' Reid will need about 50 of them in order to raise his clue index by even 1/2 a point! |

you can't see the rest of the design on purpose lol |
I actually think KelogGes is on to something with the microchannel stuff.
But, you can buy those off ebay for $55 each. I know it's curved and all, but.........just saying. |
Quote:
We can see enough, to much, really, of your air flow manifold design to easily surmise its idiocy. Bottom/sides completely covered over, no roadspeed cooling airflow. Not that your PFC design would allow for that in any case. |
If you're going to "meter" airflow at the top, inflow, then why close off the bottom?
Like I said, design IDIOCY! Quote:

I asked him basically the same question way back in post 313 and he never answered. And, he is not going to because in his brain everyone around him is a fool. Exception.......himself, but only in his mind. I guess too many days out in the hot Florida sun.

crownarch I am not sure if I want to make or market this particular interior of this shroud, it is very complex multi-part construction sandwich
it worked good, but i think the design could be much better and ever far more efficient across the coil I want to talk to other engineers about it in the future |

Micro-channel parallel flow since invented in Japan 2003 has completely taken over all other forms of heat exchanger technologies around the world Its why I can use ONLY 2 state of the art PFC's less than 1 inch thick and extremely lightweight in the original OEM placement areas on early model 911's and with a tweaked A/C system get the low air vent temps using less than ONE lb of R134A refrigerant I get Why anyone would use an older technology heat exchanger and need to run 3 much heaver and larger heat exhangers is beyond me? PFC heat exchanger technology is approximately 30-35 Percent or more, more efficient exchanging HEAT, and a PFC also has the ADDITIONAL ability to be 25-36 percent smaller in surface areas dimension size and yet still BE 30 to 35 percent more efficient THESE ARE FACTS LOOK THEM UP Porsche as well as every other automobile manufacture all switched to PFC a few years ago and never looked back. OH almost forgot Each year since discovery of PFMC heat exchangers there effiency has gone up higher to the leveal of state of the art it is today People that cling to Serpentine technology today are CHASING OBSOLESCENCE |

Buy it if you want too But it does NOT fit an early model 911 deck lid properly, its also way to small As far as I know I am the only person custom making PFC's designed specifically for early model 911's using state of the art technology front and rear other companies selling PFC's for 911's are mostly re-selling Arizona Mobile Air, Inc. | Automotive Air Conditioning Parts & Equipment china universal crap, they only have a kinda sorta a rear one that does not really fit correctly that have air gaps on the sides you can drive a bus through LoL but this one is actually better than an OEM Behr that used tube and fin technology, RennAire Porsche 911 Air Conditioning Products sells them after I refused to give him an exclusive on my PFC's after he tested a set made for him of my designs, he liked them VERY MUCH and wanted to buy them oh and so as does another a/c aftermarket 911 company I forget their name sell Arizona Mobile Air, Inc. | Automotive Air Conditioning Parts & Equipment FOR 2-3 Times what you can them direct from Arizona Mobile Air, Inc. | Automotive Air Conditioning Parts & Equipment yourself Ya want one I still have a test one I bought from Arizona Mobile Air, Inc. | Automotive Air Conditioning Parts & Equipment to test it right before I started making my own because I could not buy what I wanted and this is what led me to make my own using state of the art technology make me a cheap offer, it slightly used for about a month for testing good luck finding a pfc that will fit in front other than mine, they don't exist, to the best of my knowledge |
Thanks for the offer Reid, but I'm really far away from having a complete AC system.
I do wish you luck on getting to market, but at a reasonable price. I'm game for lightweight, efficient AC. I believe I read the entire AC system of an older Lotus Elise was 35lbs. I could live with that!! |

Anyway are you putting or have plans to install into your 930? That weight is low which is good but what about the condenser size surface are dimensions 930/s with large enter-coolers reallly cut down a/c system heat exchangers room and makes it even more of a challenge to make cold a/c |
I have a turbocharged Carrera 3.2 still narrow body.
But yes, my intercooler is full bay (width). |
I just meant, I remember reading the Lotus Elise AC system was designed super lightweight, not that I'd use one.

Quote:
Anyway that makes things HARDER BUT not impossible, although I have not installed one yet I have A small PFC for 930s 1/2 upper deck lid space, and you would still need my front PFC But why would you want to put in a lotus a/c system? or chaNge from Porsche's 911 design? not sure if that would work for you but it might? |
I agree with you KelogGes, new AC systems/components are becoming super light weight and extremely compact. Not to change your thread but, the compressor on a brand new Scion FRS is not much bigger than a coffee cup. In addition, there is not much to their condensers. That's what is great about new technology as it is always in constant change for the better.

YOU need to use your smugglers box for evaporator OEM plastic box is designed to fit it then it can be modified you dont want to make an abortion a/c The Tan Swan the Father that first had because he lived in pacific nothwest and you don't need a/c there hacked the firewall and the duct-work under the dash to put in a 12 volt heater and tossed out the a/c What a friggen pain his hack job caused and a lot of labor to fix it, The Tan swan took months of work ouch but now it has a state of the art new technology A/C system in it all custom designed |

Perhaps that's why KelogGes is making such a concerted effort to cool it electrically. 22 amps... |

I have never posted anything but true facts here I can back up with proof !

Prove me wrong

Give us a line drawing of how you propose that roadspeed forward motion airflow cools your PFC as well as would the factory tube/fin one. |
