In a review article on /the Verge/, the following paragraph made me blink:

<quote>
There is a permanent zone at the bottom for climate controls,
which persists no matter what else you're doing on the screen.
Except for the specific buttons for defrosters,
everything is controlled by touchscreen. This sounds annoying,
but the _HVAC_ system is good enough that you can usually
just set your temperature and forget it.
Even in the 120-plus degree heat of the California desert,
I didn't have to fiddle with specific fan settings to feel comfortable.

<URL:https://www.theverge.com/2017/8/17/16141366/screendrive-volvo-v90-cross-country-touchscreen-sensus>

As you can see by the underlining, "HVAC" stood out for me ... as strange.
The usage I'm familiar with for HVAC is High Volume Air Conditioning,
as in multi-story building climate control.
The V90 needs that much air conditioning?
(What happened to cars having A/C?)

The only HVAC I know is Heating, Ventilation and Air Conditioning.

This is the only meaning HVAC has in Canada. Trade schools teach HVAC,
builders employ specialist HVAC engineers because of current anxiety
about indoor air quality (cf paint solvents, tobacco, etc. V=Ventilation
seems the critical word.

You don't have HVAC power transmission there?
(as opposed to HVDC)

Not a term most people would ever encounter.

Agreed.

In the UK, AC distribution is the default so there is no need to use
"HVAC".

This document discusses some benefits of DC distribution. It uses the
initals "HVDC" but not "HVAC":
file:///G:/High%20Voltage%20Direct%20Current%20Electricity%20%E2%80%93%20technical%20information.pdf

Electric power is normally generated,
transmitted and distributed as
alternating current (AC).

National Grid owns the high voltage electricity
transmission system in England and Wales and
operates the system throughout Great Britain
at 275,000 and 400,000 volts (275kV and
400kV). The National Grid system is made up
of approximately 7,200 kilometres (4,470 miles)
of overhead line, 1,400 kilometres (870 miles) of
underground cable and around 330 substations.

High voltage direct current (HVDC) technology is one
of the technical options National Grid can consider
for the future development of the transmission system
in Great Britain.

<etc>

That document was published in 2013.

The cross-channel link from France is HVDC.

Britain is just to small for HVDC.

As is the more ambitious link to Holland,
(260 km, 1 GW) appropriately named 'Britned'.
It lands near Hook of Holland,

As a Yankee (webfoot division), I knew the current usage before the blower usage.

Okay, I stand corrected.

But it is still a new usage to me to apply it to a system dealing with
less than 30 m^3 of space.

It is more often used for commercial or industrial spaces, but is not
at all limited by the size.

That said, 30m^3 is pretty small.

the same age, always aeons deep. Terrors unfolded in the velvet shadows
and while the nature of the talons may change, the nature of the beast
does not. --Jingo

Well, it's a Volvo, not a stretch limo.

Oh, that is not in the upthread quotes.

Yes, it is certainly used as the term to describe a car's system.



Basically, if you have a closely integrated furnace and AC unit that
also have dedicated air intakes and outflow, that's an HVAC. Many homes,
particularly older ones, do not have dedicated ventilation.

When we had to replace our furnaces and AC units we went from an old
system with no dedicated ventilation to a full HVAC system.

Sometimes trimming bites the hand that feeds it,
but in the OP I was only explicit in the URL.
