Single Zone art Cool
Mirror Wall Mount
Single Zone Art Cool Mirror Wall Mount units
are equipped with inverter components that
offer superior load matching and long piping
installation. The product works for
optimizing power consumption in residential
and small office buildings. Utilizing multiple
indoor wall mount units each with custom
temperature controls allow for precise
temperature settings in each zone of the
building. Art Cool Mirror allows flexibility in
interior design and complements any decor.
low Sound levels
When outdoor units operate fully loaded,
they have one of the quietest sound levels
in the industry. Sound is almost undetect-
able during off-peak operation. To promote
a quiet, comfortable environment, the LG
Single Zone Art Cool Mirror indoor units op-
erate at sound levels as low as 24 dB(A) and
outdoor units as low as 45 dB(A) at full load.
LG customers often ask if the outdoor unit is
running after commissioning is complete.
All rotating components are soft-started
by the controller using digitally controlled
inverters, which reduce undesirable noise
caused by fans and compressors cycling on
and off.
Comfort Control at its
best
Tight temperature control through precise
load matching maximizes the time that the
indoor units remove moisture.
Unlike traditional air conditioning control
systems, which use thermostatic controls
to maintain room temperatures, LG Single
Zone Inverter controls continuously vary the
indoor unit fan speed and refrigerant flow, in-
directly providing lower and more consistent
humidity levels in the conditioned space.
The longer the indoor coil temperature is
below the dew-point of the room in
conjunction with air movement across the
coil, the space humidity level will vary little,
compared to technologies that cycle fans
and compressors on and off multiple times
per hour.
The outdoor unit responds by varying the
compressor speed and outdoor fan motors
as needed to maintain system operating
pressure. As a result, the Single Zone Art
Cool Mirror Wall Mount system delivers
precise space temperature control.
inverter driven
The rotary (9k/12k Btu/h systems) and twin-
rotary (18k/24k Btu/h systems) compressor
is optimized to maximize compressor ef-
ficiency, which reduces power consumption
and monthly utility bills. This latest inverter
technology allows the LG Single Zone Art
Cool Mirror Wall Mount outdoor unit to
vary the compressor motor shaft speed to
deliver an appropriate amount of cooling to
the indoor unit. Precise refrigerant volume
delivery translates into long periods with coil
surface temperatures below dew point and
minimizes compressor and fan component
run time. occupants remain comfortable
while utility costs are reduced.
Simplified installation
Cooling and heating systems that use the
LG Single Zone Art Cool Mirror Wall Mount
product simplify and reduce the mechani-
cal and control system design time. The
designer no longer has to be concerned
with interconnecting chilled and condenser
water piping, air-distribution duct systems,
matching and selecting chillers, towers,
pumps, coils, fans, air handlers, or Variable
Air Volume (VAV) boxes.

heat transfer Efficiency
Fin design with GoldFin™ coating
All Single Zone Art Cool Mirror Wall Mount out-
door units are provided with large surface coils
made of copper tubes with louvered aluminum
fins designed to maximize unit operating ef
-
ficiency over a wide range of ambient conditions.
Standard from the factory, every LG Single
Zone Art Cool Mirror Wall Mount outdoor
coil fin surface is coated with LG’s exclusive
GoldFin™ anti-corrosive coating designed
to prevent natural surface corrosion of the
aluminum fins. This maintains heat transfer
properties of the coil for an extended time.
A hydrophilic coating is applied to the
outdoor unit coil fin surface over the GoldFin
coating. This coating enhances the develop-
ment of heavier water droplets gathering on
the fin surface. As a result, the droplets roll
off the fin surfaces, delaying the point when
frost forms on the coil surface during heat-
ing operation. This coating also makes it
possible to easily clean the outdoor unit coil
using a mild soap.
