There is a motor/compressor combo that I've seen that can operate off of 160Vdc (Might be able to withstand 168V) The model name is Sierra, but the manufacturer eludes me at the moment. The unit is small and quiet and uses R134a refrigerant. Currently, this will get installed in the tunnel towards the rear. However, I would rather have it somewhere that is a little more accessible. (like the front) However, this area is a little full. Maybe the rear area, although I do want a trunk. We'll see...

That is the company I had in mind for my A/C compressor. I'm still not sure of the compressor motor yet. I may get a 156V+ and hook it up to my main battery bank, or I can get a 12V and hook it up to my aux. pack.
Since there are several solutions, I just wait until I'm closer to the decision, but I know I'll likely go this route.

I'm thinking about taking a 6K btu window AC and removing the evaporator coil from it, mounting it in the rear of the car and running a set of line to an evaporator coil mounted in the tunnel (I'll mount a pair of 1500w ceramic heater in there also). I figure the rear part of the package will be ~18"w x 12" tall an 8" deep, draw ~600w, and cost $125. I'll also need to get a DC to AC converter to run it.

jritt: Hi -- I have just started my build and am really interested in your ideas. I am having a little difficulty conceptually. Do you have any sketches or dimensions as to how you would build and place the 18 by 12 by 8 package and the size of the evaporater coil and ceramic heater? If I am going to have to allow for this in construction this would be the time to incorporate the design. I am adding 12 inches to the length of my tunnel so as to allow additional storage space behind the seats for a rag top etc. and now possibly an AC. I know this is asking a lot but I would love to see a more detailed write up on how you plan to incorporate this. I am an accountant so AC is totally foreign to me. Thanks

The evaporator from a 2000-2008 Ford Focus is 8.5" x 9.25" x 3.125". The ceramic heaters are approx 4" x 4.5". I'm planning on building a box in the front part of the tunnel (where the VW tranmission went into) to house the evaporator and heaters keeping the heaters above the level of the evaporator to keep condensation off of them with a blower blowing into the box and 3 ducts going to each side and the windshield. Louvers on the two side ducts can be closed to allow full air to the windshield to defog it in the winter. I am going to build an all electric rear wheel powered XR3 so I will not have any front drive components. the entire front and the main tunnel area can be used to house batteries (120Ah 144v). I'm looking at the radiator (for the diesel version) location for the AC unit. Ill also need a 3KW (I'm going to go with 1000w heaters instead of 1500w) DC to AC converter to run the AC/Heater

Ok let me bounce this off you, I'm thinking of using a cooler filled with ice, running copper lines inside, a small circulating pump and a coil w/fan in the cabin. Just thinking out loud....I think the coil in the cabin would have to be large enought area to really do anything. Anyone have thoughts on this??? Scooter

I've just started work at Linde fork truck. I was able to speak to the outside company that installs the ACs in the fork trucks. He didn't think there would be a problem using it on the diesel. And they are small. I'll have to look at the manufacturer.

Hi Scooter.
I just got back from a European vacation, so I was out of the loop for awhile.
I remember reading sometime ago, about a fellow that used those plastic, re-freezable, blue-ice things. He designed his cooling system, so that he could plop these into a tank holding a small amount of water. I think there was a small heat exchanger hooked up to it. Cold water would flow into the exchanger and a fan would blow on it. The resulting air would be quite cool. The now warmer water goes back to the tank for re-cooling.
Some google-fu might turn it up again.

Here is the compressor model number. # SIERRA06-0982Y3 with controller board for 150V/300V Details can be found here for it; www.masterflux.com/products/sierra/?pid=51Cost: $1300-$1500 I know it sounds like alot, but have you heard the saying, "you get what you pay for"? This compressor has variable pitch vanes and other techy controls to reduce the operating power consumption as much as possible. It was noted that the compressor needs to get a little airflow, so I'll have to see about directing some outside air into the tunnel. Should be no problem there. The controller card needs cooler temps, so it may be in an area where air can flow more freely around it. I spoke with John at www.flightlineac.com. He deals with airplane A/C units, but is very knowledgable on the compressors and what they can do. Note: I still need to find a condensor and evaporator coil too, that will suit my needs.
