Split Air-Con power consumtion

Hi group,

I am wondering if I leave just one unit of my 4-split air-con on,
will the power consumption be the same as leaving all 4 units on?

I was thinking if there is only one compressor, then switching on just one unit, would 'take-up' the
whole compressor?

I for one do not understand what your talking about.

I have had my head in the clouds for years, so it is probably all me.

Assuming that your air conditioning compressors (actually condensors)
run continuously, running only one will consume only 1/4 as much
energy. This, of course, assumes that each is a totally different
system.

I have no idea what your second question means.

Ok, LOL!

Ehh...what do u mean ' totally different system'?

Probably a stupid question coming up.
Just how many condensers does a split air-con system have?
I can only see one 'physical' box outside my home which all the 4 air-cons are connected to.
Someone once told me that this 'box' can contain about 2 or more condensers serving different
air-con units.

Actually, it is the compressor that runs. The condensor is just the heat
exchanger that rejects the heat.

It will consume less, but not necessarily 25%, since the one may see a much
greater cooling load than it does when four are running, so the power into
it will go up.

Eh...but what if the all the 4 air-con units are in separate rooms?

Assuming all units are for the same room, which I don't believe it is the
case, the one unit left on will work non-stop to keep the desired
temperature down.

The net results:

25% < electrical consumption < 100% (depending on the outside temp)
Premature compressor failure, that is costlier than the economy you're
trying to achieve.

You are better off keeping all four running with slightly higher temp &
lower fan settings when you're not home. That way the four units share the
load confortably.

I'm not sure I would agree with that. If the continously running compressor
is operating within its normal design suction/discharge pressures and
temperature, it may last *longer*. Frequent motor starting is a common
cause of overheating. A lot of mechanical wear happens during startup if
the lubrication is self-fed. Wouldn't surprise me if it can be run
continously for quite some time. As long as the condenser coils can be kept
clean and it doesn't develop any refrigerant leaks.
