this is a rooftop a/c in a car.

I dont feel any of it is real heavy. Condensors are as thick as an oil cooler (20mm), The bigger the surface area, the better cooling, most come with mountings for receiver driers on the sides of them. Compressors are sized for motors, so using one off a 2litre motor on a A series would be putting pointless load on the motor. A compressor sized for a 500cc - 1400cc motor, is a little bit bigger than an EA ford 80amp alternator. Using a smaller compressor on a bigger motor is not a problem. The bigger the cabin area, the more gas you want to compress quicker, thats when you want a bigger compressor, Just like house A/C systems. You can mount the compressor on any side of the motor aslong as you (a) make the mounting, and (b) line it up with a pulley so the belt runs smooth.
The evaporater works opposite to a radiator, Where as it cools the air blowing through it and removes the moisture (humidity) from the cabin. This moisture is dumped through a drain tube to underneath the car. Any auto elec that does A/C will have a catalogue you can look at which has dimensions of aftermarket underdash units.You can still buy the similar style units as to what nissan dealers fitted to 1200s.
You can easily fit up the components yourself. The underdash units require basic wiring ( easier than a radio) and they come with diagrams.
You can buy the rubber high and low pressure lines buy the metre from pirtek etc, cut it to length and then get the correct fittings crimped on buy the same shop etc. Then oil and gas at the auto elec etc. Most aftermarket fitouts use a rpm trigger which cuts out the compressor below a set engine rpm, this makes engine idle not difficult at all.

Most of its pretty heavy, condensor is like a radiator and would sit in front of radiator, compressor (same size as 2 alternators) sits on passenger side of engine(A-series 74+) and then evaporator sits up under dash and takes in air from cabin cools it then sends back into car so would have to plumb hose from that into hoses that run to demister i guess. As for hoses that carry the gas, i would use the ones off donar car personally.
I dont know anyone whos done it, but i think ive got it layed out in my head. The only complicated thing is the wiring, idle setup etc, and getting the air into the cabin properly.

so what is exactly needed to A/c a 1200. You need a compressor, condenser, evaperator (how bulky are these parts?) Then tubing? What tubing is used could you make it up yourself?

electric AC compressors

there is a contact in AU for these

you'll need 100AMP alternator to run them though.

Whitesedan there is a difference between having a joke and being a smartarse. Being first to reply to someones question with a smartarse comment, isnt funny. Think about it. Its all good to ignore it but eventually it brings down the quality of the forum in everythread.

Cable_tie - perfect!!!

That is classic Cable_Tie! I lived in South Florida and in that humidity even this doesn't seem like over kill. Also love the repositioned tail lights after someone side swiped this car in shock.

Hey, Matty!

You lookin' for something like this?

My partner has seen this thread and now she wants a/c for her 1200, ive seen quite a few 120y's with aircon. Might just use a switch instead of choke on dash. Also could fit evaporator unit up under glovebox maybe making a different glovebox card would give more room, i have one of those coupe trays that go under the glovebox which would hide all the wiring etc. The compressor itself will bolt up as its an a-14. Its just finding the unit and having a go i guess. Probably have to run a later model hitatchi carb for an idle compensator and auto choke so choke holes free. At least I will have a valid excuse for going to u-pull-it this weekend.

Oh and run elec fans so can get condensor up front, it'll be a squeeze!
