Gday blokes,
One of my subscribed channels on youtube called Davidsfarm has just posted a video on the workings of airconditioner and fridge compressors just incase you are interested.

Nice find. I never quite understood exactly how awesome a rotary pump is. They are so ingenious!

Have a look at a scroll compressor,now thats ingenious!
And great find on the video,it's going to help me alot with using my fridge compressor which I have lying around I never could tell which was input and output and why there was 3 of them.Thanks.

Good videos and worth a watch. I liked the scroll (air con) pump mechanism..

This guy has lots of videos like this. After I watched the compressor one, I ended up watching 4 or 5 of his others. His down to earth delivery make him easy to listen to.

yea starman i watch all his vids very imformative and very entertaining.
it was him that got me into fixing old small engines.

awesome vid... I've never seen insides of a rotary pump
I find it esspecially interesting as it's spoken language... it's very difficult to find info on prenunciation of tech related vocabulary.. not to mention that it's hard to find them in dictionaries

And not a finer example of the Canadian dialect are you likely to find than this guy's...

ohh that's even better...
besides his english sounds more refined than american english
BTW at the end of this vid the guy said that 'fridge compressors can provide about 150 psi while AC compressors about 300 psi'
well, guess what some time ago I asked ralphd (he works as HVAC engineer) about fridge compressors, AC compressors and possibility of using them as airpumps... and he told me exactly the same thing
now... does that mean that at least in theory AC compressors should be able to deliver twice as much pressure as fridge compressors can ??
ps. sorry for hijacking every thread that has something to do with fridge compressors
but how many of us have fridge compressors ??

dont worry about jacking it mate, feel free to talk about them.
i love the look of the ac pumps ay!
what would the flow be like though?

I noticed that too.
Probably working pressure.
Maximum pressure output, however, may be a different thing.

well yes.. you don't know if and how much more pressure youcan get from it...
but the thing is that the biggest drawback of fridge compressors is their relatively low flow which limits their utitlity for larger guns... but apart from that they are ideal
AC compressors should have enough flow for most uses... and they are easily available - at least in the US
