Low Ambient Cooling question ???

[kefah]

Hi guys
im live till now
i found on this
in Samsung air conditioner site
the specification for 2400 unit
classic split air conditioner


is
Low Ambient
Cooling
15 ~ 52°C


i think low ambient temperature means cold area
and hi ambient mean
hot area
so how its low ambient cooling and it works in extreme condition to 52 C

Temperature difference!

AC work at about +20 if the ambient is lower than
the temperature in the room to be cooled, you have no
temperature difference.

can u explain more

If you are referring at low ambient as described here in these specifications:
http://www.samsung.com/global/business/system-air-conditioner/system-air-conditioner/residential/AR09HSFNBWKNET-spec

than it mean that cooling of indoor air is possible even at outdoor low temperature as -10°C.

in the site they mentioned Low Ambient
Cooling
15 ~ 52°C
so low meaning it can cool even at 15 C ??????
is that the meaning

Can you post link to that site?
Probably it is typo. Low ambient usually mean for outdoor temperatures below 0°C (or maybe 10°C)

Most of AC units normally run at 15°C outdoor. There is noting "low ambient" about that.
Some AC unit cannot cool below 18°C or 16°C indoor. That is limiting factor because of evaporator TD. If it is lower than that, it would require indoor coil defrosting function.

Units with no condensation control (outdoor fan speed control) can have some problem at outdoor temperatures below 20°C because of low condensation pressure. Effect is lowered cooling capacity!

check the tech spec (http://www.samsung.com/levant/consumer/home-appliances/air-conditioner/wall-mounted-split-ac/AS24UUQXSG)

As I investigate further i found that that unit is of non-inverter type and with UTR compressor.

That should be good choice for your enviroment.
Why would you need cooling for ambient below 15°C?

may be for server room ??
here the temperature vary from up to 50 C in summer]
and 0 C in winter

Check these specifications:
http://www.fujitsu-general.com/uk/products/split/wall/std/asyg09lmca.html

Here it is low ambient cooling to -10°C.

I dont see reason why should Samsung not do that if it is inverter technology with outdoor unit fan speed control.

BTW here in Europe, all new AC unit must be of inverter type!

all unit we have here are classic
non inverter
