Is there any way to increase the efficiency or capacity of the air con. like installing a bigger radiator/condenser (for lack of the actual name) for the ac unit. If my car has been parked in the sun it just can't lower the temp. I get in and drive with the windows down for about 5 min to let all the hot air out then, put them up and set the ac to 23C on recirc and it can't get the temp down. Feels like it gets to about 26. I don't think the system is big enough for a car with such a large cabin(including boot) and a huge magnifying glass on the back. Any sugestions? Are there any tests to make sure the ac is working at 100%?
It might sound like a silly question but have you had it checked out? In my first Zed the aircon worked well and cooled the car nicely. My current Zed it doesn't work at all and gets stinking hot. It's black with black leather. I've just had an air con compressor rebuilt and I'm having the entire system over hauled when the new engine is being put in. Hopefully get that done before the weather heats up. Cheers, Evan.
It's always very hard to cool the car down after baking in the sun for a day. Before it can properly keep the cabin cool, it needs to lower the temperature of it's piping and vent ducts, then it needs to cool the surface temps of your dash, seats, trim etc. before it can relax and just maintain a constant 23 degrees. Things that help big time are: - Tinted windows (a must for keeping temps cool in cabin) - Use a reflective windscreen cover - Also get a cheap one and cut up so it fits inbetween your targa glass and targa shade, as this reflects a surprising amount of heat from your head. (if you have a T-top) - If you're parked in a a safe parking area that you trust, leave both windows down a crack, to allow air flow. Or if it is in fact not working at 100%, it may need a service and/or regas. I had my a/c system serviced and regassed, etc a couple of years ago, and it freezes my balls off in no time even in the sun (mind you, i also do all those things in my earlier list whenever i leave in the sun) :zlove:
Theres no problems with the stock air cond,like ev said,go and pay to have it inspected and maybe get a fresh refill ,its probably low or you have leaks
And don't forget, if you are told you need a retro fit, go find a hychill distributor in your area and get them to regas it for you. Works more efficiently than a retro fit so I hear. And cheaper.
i wasnt going to say that after the fiasco about hychill last year,but i agree,seems like a much better option
I do all of those things ben but I have no targas so I can't do that. Also have tinted windows. And to top it all of I had a reco compressor installed with new gas about 1 year ago. I guess it could be leaking somewhere.
Why are you setting the temp to 23C, wouldnt you put it down to 10C (lowest setting)??? I also find for my zed anyways the recirc dont really circulate the cabin air at all but rather turns the aircon system off completely. IF i was you i would always set the temp down to 10C and let the aircon blast at High until you want to raise it again.
Mine worked great until it just stopped working completely Have all the parts now, getting it sorted after Xmas
Iit's climate control not a manual fan, if you set it to 23 it blasts as hard as it can to get to the deired temp, then once reached the fan and cooling slows and keeps the temp constant. If your going to set it at 10C then adjust it when it gets cold you might as well have a manual system. Setting it at 10C will only mean your aircon is working flat out all the time because you will never get it to 10C, well in QLD that is. I have this argument with people all the time who don't understand how a thermostat works. Set it to the desired temp then leave it, the unit will do the rest. I have this woman who comes in every morning at 8:30(I get in at 7), I have the ac set on 23 C auto and she puts it on 18C with the fan on manual maximum all day and I freeze.:bash: Also it the rec button turns of your ac it's not working properly.
I'm similar to the above. I'll turn it down to 15 or so and leave it on that. If I get to cold I'll turn the fan down to Low, which is usually fine. Seldom is the cabin ever cold enough that I need to turn it up - but if I think that its close to where I'm happy, I'll move the temperature up to 21 or so degrees.
AAARRRHHH!!!! It's climate control fu(king use it properly!! Or don't...you'll only prematurely wear out your ac.
if you have manual ac with knobs yeah do what you want, but if you have the digital unit the whole idea is you set the temp and let it do it's thing. Setting it lower than required is only forcing it to work hard all the time till you stop it or it breaks. As a rule do you manualy change gears in an auto?
max ...23 degrees is not all that cool...!!!! .. i would be setting at 20 degrees .. and see how you go ... .. my system has worked well for 4 years .. you may need an overhaul ....
It's not an on/off thermostat though. As it gets close to the required temp it slows the fan speed. So if your system is in crappy condition, it might think it's ok to go at low speed when you set it to 23 but it just isn't enough. Try lower so it's operating at 100% capacity and see if it gets cool.
I pretty much always set mine to low fan speed as soon as I get in the car and the only reason I do this is because the fan at full speed is too bloody loud! Ben
max ... if you know it all ... then do NOT ask ....!!!! AS I ALSO SAID .. go get the bloody thing checked out and overhauled .... .. over and out for me ...!!!! ..so much for young engineers ... !!!!
As you can see from these posts. the 300ZX aircon in good nick is more than up to the task. Mine works so well I can't transport brass monkeys any more. The 300Zx system is a full time aircon (no compressor clutch clicking in and out) and it maintains the desired temperature through a movable door that mixes the hot and cold air. That is controlled by a sensor gadget in the roof under the plastic surround for the overhead light. Probably the same place in a slicktop - no idea for a convertible. That gadget has a fussy little fan that draws air across the sensor. A couple of things to try: Borrow someone's sensor control unit and try it in your car. Yours might be misreading the internal temps or have a broken fan. Do a temporary heater bypass. If your a/c temps immediately go arctic, then the problem is in the mixer door mechanism. Maybe its jammed.
