PRODUCT FEATURES AND BENEFITS

Single Zone Mega Wall
Mounted
Single zone systems are equipped with
inverter components that offer superior
load matching and long piping installation.
These products work for optimizing power
consumption in residential and small office
buildings. Utilizing multiple indoor wall
mounted units each with custom tempera-
ture controls allow for precise temperature
settings in each zone of the building. Single
zone systems allow flexibility in interior
design and complement any decor.
Low Sound Levels
When outdoor units run at full load, they
have a quiet operating sound level. To pro-
mote a quiet, comfortable environment, the
LG single zone system indoor units operate
at sound levels as low as 23 dB(A) (HXV
units; 19dB(A) in Sleep mode) and outdoor
units as low as 47 dB(A) at full load. 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
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.
LG single zone one-to-one systems continu-
ously measure the room temperatures and
adjust system operations accordingly to
maintain set temperature.
The outdoor unit responds by varying the
compressor speed and outdoor fan motors
as needed to maintain system operating
pressure. As a result, single zone systems
deliver precise space temperature control.
Inverter Driven
The single rotary (9k/12k Btu/h systems)
and twin-rotary (18k/24k Btu/h systems)
compressor is optimized to maximize
compressor efficiency, which reduces power
consumption and monthly utility bills. This
latest inverter technology allows single zone
system outdoor units 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, which may lead
to lower utility usage.
Simplified Installation
Cooling and heating applications that use
single zone systems simplify and reduce the
mechanical 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.

Operating Range

Single zone systems have a nominal capac-
ity range of 3/4 to 2 tons (depending on
outdoor/indoor units).
Outdoor unit operating ranges for both Mega
Inverter (HEV1) and Mega 115V (HXV)
single zone systems:
Cooling: 14°F DB to 118°F DB
Heating: 14°F WB to 65°F WB

Fin Design with Gold-
Fin™ Coating
All single zone outdoor units are provided
with large surface coils made of copper
tubes with louvered aluminum fins designed
to maximize unit operating efficiency over a
wide range of ambient conditions.
Standard from the factory, every single zone
outdoor unit coil fin surface is coated with
LG's exclusive GoldFin™ anti-corrosive
coating designed to prevent natural surface
corrosion of the aluminum fins. This main-

tains 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.
