    Hi Jeff - I have a 1985 911 with factory AC that barely cools. It has the same small side vents, but also has a center dash vent which works well for fresh air. In any case I'm very interested in seeing how well the electric retro-fit AC system works. Keep up the good work and excellent videos!

    Oops............at around 19:30 you mis-state the basic air conditioning cycle. The whole process can be done with ordinary air (that's how most systems work in airliners) but it is much more efficient and compact for an A/C system to use some sort of special gas which can change state from a liquid to a gas and back again at reasonable temperatures and pressures. "Freon" R-12 is the familiar stuff from days past, but these days cars usually use 134-A or the newer R1234YF refrigerant.
    The compressor discharges hot, high-pressure gas. This gas then goes to the condenser (not the evaporator as you say) where the hot gas is cooled and turned into a high pressure liquid. Since the hot gas not only gives off it's heat, it changes state to a liquid as well; therefore, the amount of heat rejected to the outside air via the condenser is even more dramatic. From there it goes to the expansion valve near the evaporator (inside a box under the dash) where the high pressure liquid is expanded and converted into a lower pressure gas. Any gas cools as it expands, but by also changing state from a liquid to a gas, the resulting heat absorption is more dramatic. As this cool gas travels through coils the box, a fan blows cool air into the car. The cool, low-pressure gas is returned to the compressor where it is again converted to a hot, high-pressure gas thus completing the A/C cycle.

    • @Roberto-oi7lm
      @Roberto-oi7lm 2 ปีที่แล้ว

      @@DiscoFang Strictly speaking, the receiver/filter/dryer is not part of the air conditioning cycle. The system will operate without it; perhaps not for long, but it will function. The receiver/filter/dryer, as the name implies, has three functions. It provides a reservoir of refrigerant, it filters out any crud, and it has a desiccate to trap water because a tiny bit of water can freeze in the expansion valve and shut down the whole system. Often these three functions are handled by an all-in-one unit, but some systems might contain separate components. A typical receiver/filter/dryer also includes a glass sight gauge so you can see the refrigerant. And yes, as you say, it's important for a well tuned A/C system.

    Hey Jeff, plug those open hoses to avoid any contamination while building the system. Small particles can ruin the compressor. Also water from the air can enter the dryer and saturate the desiccant and the PAG oil as it is hydroscopic. I assume you are using 1234yf refrigerant otherwise you must have a RHL.

    Not a bad kit, although for the price I'd expect better mounts than some zip ties. Overall though it does go together quite easily. Some ducting for the condensers would probably help with air flow especially at speed to make things super chilly 😉

    This is a great idea for any car without factory A/C , but I'm not convinced about the long-term use of those hose clamps, I would advise checking locally if you can get a proper A/C hose crimper with the correct crimping collars for this hose and fittings combination. I hope that you have access to the correct vacuum pump and manifold gauge setup to evacuate the system correctly after leak testing with oxygen free nitrogen. I would imagine that this setup would outlast any conventional belt drive compressor system as it's isolated from the heat and vibration of the engine and with no shaft seal to leak this is a winning setup 👍

    • @ClassicRetrofit
      @ClassicRetrofit 2 ปีที่แล้ว

      The hose clamps we used have been used in motorsport for around 20 years now. They are rated far in excess of the pressure of the pump and higher rating than most hydraulic fittings. They also do not rust out since there is no ‘collar’ for condensation to get trapped behind.

      The hose and 'Oetiker' clamp system we use meets SAE J2064 rev 2015 which calls for a working pressure of 500 PSI for AC systems. Max pressure in our system is typically 250 PSI. Oetiker clamps are used all over modern vehicles, including in high pressure fuel injection systems.

    I can't help being captain obvious here. The fact that the A/C is not pulley driven but electrical makes no difference to how much engine power it will eat up. Kilowatts is kilowatts. When you turn on the A/C your new beefier alternator will need to generate as much power to run the A/C would've taken when driven by the crank directly.

    A "quality kit" that includes sticky tape and cable ties to secure major components like the dryer and the fan shrouds? Given the impressive standard of your build(s) you surely cannot be happy with these fixings? I wonder what will hold in the evaporator! Otherwise the kit is quite impressive and your videos are the kangaroos b*****ks.

    • @ClassicRetrofit
      @ClassicRetrofit 2 ปีที่แล้ว +1

      Wrong. The parts are mechanically fixed by other means (fan shroud is bolted in). Zip ties for securing only as per any modern production car. Tape supplied is a gasket for providing air right seal.- it is NOT used to ‘stick’ anything - it isn’t even adhesive.

      @@ClassicRetrofitJeff sorry if I have offended you and prompted your touchy riposte. I seem to remember your line " I will just pull off the backing to the sticky tape and install the condenser to the shroud with cable ties in all corners". Also the dryer is secured to its bracket with two cable ties. I have a number of modern and classic cars which I look after myself and I have to say none of them have components attached with cable ties . The only place they are to be found, as their name suggests, is for "tying cables".

      DavidG Jeff is installing our product. The inference of your comment suggested that our product is not high quality based on the use of zip ties. In this application of zero load, this type of fastening allows easy removal of the shroud for cleaning the condensers from the back WITHOUT having to de gas the system. There is always a reason behind engineering choices. P.s. the paper backing tape is ‘stuck on’ but the foam is not sticky - semantics.

      @@ClassicRetrofit It is disappointing that Jeff has seemingly gone to ground and is relying on a third party to make his response. It is noted however that contrary to Jeff's original statement there is now no denial that sticky tape and zip/cable ties were used in the installation of key components. I note the supplier/sponsor's comment that the condenser is under zero load and would be fascinated ,as an engineer, to see the calculations that support that analysis. The comment regarding cleaning the condensers without de-gassing as a reason for using zip-ties is also somewhat tenuous as the condensers are plumbed with flexible piping which would not inhibit their removal from any type of mechanical fixings whilst keeping the installation fully charged. As we are protracting this discussion I would also suggest that fixing the condenser utilising only two mounting points is also, in my humble opinion. far from optimal due to the diagonally imposed torsional forces. The cuddly Jeff I and so many of my Porsche owning friends so admired seems to have gone off stage and been replace by a corporate spokesperson!
