Not your typical HVAC system., Looking for alternatives to conventional HVAC system. Options

[Literati914]

..; has anyone tried an alternate condensor to cutting the frunk floor?? Just wondered if there's scope to mount one in the engine lid (possibly a narrow condensor in a double 914-6 lid) and still isolate it from the hot engine compt air below - or is that just unrealistic??

I'd love to fit one but don't want to cut up the frunk?

If I remember @ClayPerrine mounted an AC condenser (from some model of 911?) under the engine lid with success.

Also - don't I remember some talk of someone adding AC to the inside of the fresh air box? Don't remember any of the details .. but that seems like a great idea if it could work. Me? I have two 914s that have both had the frunk floors cut for AC, but nothing else AC related - and I'm gonna have to have air in at least one!

I like the ideal of electronically run ac and heating system that will not rob power from the engine.

That's not how physics works though. A large electrical current draw will still rob power from your engine.

I agree (IMG:style_emoticons/default/agree.gif) You can neither create nor destroy energy, only change it's form

I added an additional condenser in series with the one in the front trunk. It is from an 911 SC, and it mounts to the engine lid. With the R134a conversion, it helped to lower evaporator output temps to the point I could get the inside of her car down to the high 70s on a 100+ degree Texas summer day. I didn't remove the original condenser, I just supplemented it.

It makes the engine lid require a prop rod, but it does make the AC nice and cold. But there is not room on the engine lid for a condenser big enough to handle the whole load, and it will make the engine run hotter too.

' Swamp Coolers ' or, more accurately,
' automotive evaporative adiabatic air conditioner ' : an electrical load on system, carrying a few gallons of water, filled regularly in summer, most useful in dry, hot conditions.
Works on chilling air-cooled engines too !

Pulling an entire AC system from a wrecked van would work too, for a cheep compromise, though some reverse engineering would be required.
Driving the compressor's input shaft is the first task, a 12 volt electric compressor is an option, and a simpler solution if sourced easily.

What options are there for A/C & heat for a 914 with V8?

There are under dash units that support both AC and heat.

@914forme Sure Stephan. BTW Steve has seen my setup. I went with the Vintage air unit because of the depth of that unit. Everything I found was 12" depth except for this one particular unit they sell that has a 10" depth. Even then it is a close fit. The closer is that you don't need to cut or drill new holes in your lower dash/knee pad. On the right side I bent one of there supplied straight hangers 90 degres. On the left, IIRC I bent another supplied hanger but more of an "L" shape. You use the OEM screws if long enough or a 6mm x 25mm x 1.25. Regardless, it fits the 914 like a glove and does not protrude past the knee pad. I can list the part # but AFAIK it is the only unit the sell with a 10" depth. A little under $500 whenI bought it.
