Daikin Inverter Drive Reverse Cycle Condensing unit

Just hack the pipe and let the gas blow out to the atmosphere? ...... Are you a licensed technician?...... I know at the time you made this film, you were not certified.... rediculus!

[Aussie50]

@camry6 why would I waste time and money with EPA paperwork and other shit associated with holding a licence?, all the techs I know gave up their tickets because of how bad the industry got fucked over.

oh yer, one of the main reasons R410a was pushed on the industry because it was touted as environmentally friendly, compared to the 'evil' R22 (which I do get reclaimed BTW)

[Aussie50]

@camry6 I notice your in the US so I must say you have it VERY easy when it comes to getting licenced, its easier for me to own a .50BMG rifle and a closet of other guns here, than it is to buy and hold HVAC certs.

@Aussie50 In Washington state you just need to fill out a form lol

[DJYellowjacket]

R410A does not contain any chlorine atoms, which is what depletes the ozone layer. Go back to school. Tired of hearing all the crap about global warming too.

[181jose]

i have 1 daiking 1 mitshubishi AC at home. I ran the daikin for 12 years it is still silent never broke down i never eaven called a service to check it out it works perfect by me they are the best on the market!

[fedders4]

@181jose I think you should buy a new one, just for the energy savings!...12 year old air conditioners are out of date!

[fridgy5822]

you have no idear

[Aussie50]

theses always a first time for everything :p

[jt2013]

You have to reclaim all refrigerant. R410a is global warming. You must not be a Fridgy because you know nothing. Your a wanna be fridgy

[Aussie50]

Lol!,guess again, I'm a scrap man...

[justinaurelius]

there is no such thing as global warming.

[jbaur]

Dude. You can not just send R410A into the atmosphere. It still needs to be pumped down and recycled properly. R410A has a high global warming potential - very similiar to R22. Also, almost all heat pumps have a time delay. approx 5 mins.

[Aussie50]

Since when is R410A an ozone depleting substance?. the whole idea of changing over from R22 was to avoid that problem!

Just like R134a, no laws to prohibit it being released to open air because its not classed as ozone depleting.

[xxShlongaxx]

@Aussie50 This is taken strait from the codes of practise and it is illegal! Section 1.2 Refrigerant venting

1.2.1 Where the release is avoidable, fluorocarbon refrigerant must not be willingly

released to the atmosphere by any person by any means, including:

(a) venting refrigerant directly, and

(b) charging refrigerant into equipment with identified leaks.

@Aussie50 You still cant vent it into the atmosphere in US, EPA will buttfuck you

they say it is better to leave a computer on 24/7 at buissneses becuase of this ,turning them of and on every day can

reduce the life of servers and other computers,heat cycling is a bitch,ask nasa,by the way nasa sucks dont ask them any thing ,lol

[Aussie50]

I here ya there on the computer, the office comp at work is left on as a net server 24/7. I shut it down one day to clean the dust out and lubricate the PSU fan (was chattering like mad). When I popped the lid on the PSU I noticed the electrolytic caps on the 12V rail were bloated and leaking electrolyte.

Sure enough, after 4 years of running, no start up!, the caps couldn't handle start up current!.

[Aussie50]

I'll have to set up the Daikin with a evap coil and run it for a while. it could indeed have an intermitent fault that starts after 30 mins or so. the main PCB is coated with a thin coat of epoxy so resoldering may be a bit tricky.

any way at such small lengths the differance can cause the solder to brake away in a cylindrical crak causing mechanical seperation on a micro scale

when the device is tested proding it with a tester can ingage it making it the biggest fkn nightmare in the world, remember this next time you use a meter push the probe to hard can correct the failer durring the test ...what the ...and it is triky bro i almost threw away pmw because of this phenominon,thay say it is better to leave,,,,

[NOBOX7]

have you ever heard of solder fatigue

i cant spell but any way electronics that elaberate are suceptible to micro seperation they are brakes in the solder

vissible only by x ray's,what happens is the connection of solder is joined to a metal of nonconcurrent coeficiant of expansion over time heat up and cool down can cause the brittle solder to experiance an osilation of .000003 m this is small but becuase the elastic limit at such small lengs say .7 mm on a solder joint it will brake away.

[Aussie50]

Yeah man! I'm very failure with solder fatigue!, I've always called it "dry joints" simply because they often look crystallized and dried up/cracked

When i was in high school I did work experience for 3 years in a TV/video repair shop fixing many dry joints. especially in older model Phillips TV power boards!

[NOBOX7]

very intresting ,,have you ever found a joint that doesnt work but when you press the meter on the component the dam thing works,,?? a fuse housing did this to me resently and i nearly threw my speed controller into the scrap closet,any way dry joints i like that term ill use it

[Aussie50]

Many a time!, its actually a good form of troubleshooting erratic faults, patting the cabinet or gently tapping the PCB on a TV will often show up dry joint related faults like picture or color loss.

High wattage resistors, transformers/flybacks and CRT neck sockets all seem to be the worst offenders, along with IC's and heatsunk transistors.

Some PCB's are just really poorly soldered, like the early Sony Trinitrons and need 90% of them resoldered.
