Your clear out a left field, over the fence across the parking lot rolled
down the hill and into the friggen creek here man.
But if /when you happen to find some manufacturer of resi split or rtu that
doesn't presently supply a low pressure cutout as standard equipment then be
sure and let me...
So go ahead, always replace it then if you insist really I couldn't care
Actually, suggest you might consider learning to USE the pt chart where it
concerns validating the presence of non-condensables or contaminated
refrigerant--Hint: pretty sure it's still a standard sample question on most
of the 608 tutorials.
How many will it take before you admit you're wrong???
Most ICP schematics will have asterisks, in this case it's simply an
artifact from when those switches were an option.
Do you really think any compressor manufacturer would honor a warranty these
days where the unit manufacturer doesn't include safeties ?
Suggest best to look at the sales brochures, unit specification, or
engineering submittal sheets.
The paper below covers models you refer to earlier and by reading the very
first page you'll find the unit does indeed have safeties installed at the
Take a look at the spec sheet...
Compressor warranties??? They've been covering compressors for years that
didn't have low and high pressure switches. I suggest that you remove your
head from your ass and take a peek out in the real world. Geez, where have
you been your whole life, under a rock?
There are units manufactured today *without* pressure switches.... oh no,
the world might come to an end.
You're such a clueless wonder.
Among other conditions, a venturi requires the "hole" to be located at an
area of greatly increasing velocity such as at or quite near to an area of
Sure thing--the Flying Spaghetti Monster is the creater of the unviverse,
The link showed a page but no article.
One thing I've learned is that if someone has it in their mind that
something isn't so, no amount of talking is going to change a mind
that cant be changed.
Pretty much everyone here is full of themselves. Recent examples and
Im not picking on anyone but when someone says that someone is going
to freak out when they see a couple of circuit boards in a HP, well
that's a little over the top. Circuit boards have been around for a
coons age. Power in power out no big deal. Then to go on and say
that commercial/industiral techs don't know squat about resi equipment
and blabbing about some mythical union bench are just showing
ignorance or are jealous or something.
Union service techs are never on a bench. On the construction side
they may be but that's the nature of the work. In my shop we can have
and have had upwards of 200 guys working or it could be down to a
handful depending on who gets what bid and if anything is being built.
Winter is slow for that side because of frost laws and construction
generally grinds to a halt.
My best advice is to take these guys with a grain of salt and do what
you do the best you can. No one is going to learn anything here they
already think they know it all. Usually the ones who boost the most
know the least. I see it here damn near on a daily basis. There's no
need to try and show anyone here anything because it aint gonna
For me, I just like to stir them up once and a while. :)
Daltons law applied.
The link worked.
A Sporlan publication also states that you can measure the condenser
temp midway on the coil and compare it to the liquid pressure
converted to temp. A deviation of a few degrees indicates non
condensibles. This can be done with the unit running.
Actually what it say verbatim is;
The proper use of the P-T relationship can be helpful in discovering
the presence of air or other non-condensable gases in the system.
This would be revealed by the measured temperature in the condenser or
the leaving temperature of the cooling medium being much lower than
that indicated by the P-T relationship.
