What am I missing in this local video?
"The cold temperatures are already causing pipes around the Las Vegas
valley to burst. Sharie Harvin looks at things people can do now to
prevent a problem. "
She talks about HVAC condenser lines, etc. In all my days, I have
never heard of such bursting from cold. I'm talking about from
outside cold temps.
How cold would it have to get the refrigerant to freeze solid ?
I have a feeling if it ever got that cold where I am , I would move.
What are the lines on the roof ? Do they put water on the roof during hot
days to cool it off or is it a way to heat water ?
Here in humid Alabamastan, the only places where you will see swamp
coolers are places like manufacturing plants and outdoor areas. I did
service one for a dry cleaning plant because it got very hot in there
and the energy cost for air conditioning would have been prohibitively
expensive even 25 years ago. Yes we do get freezing weather down South
but it's actually rare for pipes to freeze. I remember it having to get
down to -10Â°F or lower for a few days before unprotected pipes under a
home would freeze. I did a repair for an idiot car dealer who left a
full water hose on his through the wall frost proof sill cock. Most
folks put an insulated cover over any through the wall sill cock or
insulate any pressurized free standing outside water faucet. Many homes
have a valve on the inner basement walls where an outdoor spigot may be
so that it can be turned off and drained. ^_^

The goofy reporter was pointing out the low pressure refrigerant line,
not a water drain line. The low pressure refrigerant line will develop
frost at times and even build up quite an ice covering in conditions of
high humidity in hot weather. It should be insulated in the interests of
efficiency and to keep condensation from dripping off of it and getting
into where it penetrates the wall. Of course it's insulated all the way
to the evaporator coil on the air handler/furnace. ^_^
We're just coming out of this cold wave. Last week we recorded -34C,
Wind chill of -44C. Received little more than a foot of heavy, sticky
snow. No problem at all. No pipes busted, cars started fine. No power
outage. It's pretty cold my dog won't even go for a walk all week. Whole
week he was inside, this afternoon I took him out for half an hour or
so. Now it is only -14C.
One tip from my fire investigation past. For those of A Certain Age,
you will remember the infamous "Freezer Bowl" game in '82 between the
Bengals and Chargers. It was around -35 F with windchill.
We got a call around half time of a fully-involved apartment complex
that the FD had put out, but needed investigated. We rolled and
(fortunately) did not take too long to find cause.
In a attempt to stop the pipes from freezing the maintenance dude
had packed the crawlspace with straw. When that didn't work, he cleared
the straw from the area that was frozen (so far so good) and started to
thaw the pipes using a torch. What he forgot (or more likely did not
know) was that the heat would be transferred along the pipes til it hit
the straw which kept it from disipating and eventually caught fire. We
were really amazed that it wasn't a fatal fire.
Statistics are like bikinis. What they reveal is suggestive,
but what they conceal is vital.
