Duct-Free Split (DFS) Systems
LG HVAC systems offer a range of solutions that are cost efficient,
quiet and attractive. Duct-Free Split (DFS) systems are “split” into
indoor and outdoor units, and provide a smart alternative to both
central HVAC and window-mounted air conditioners. These inverter
heat pump systems are available in a variety of configurations to suit
different cooling and heating situations. Installation by a qualified
HVAC contractor is safe and easy – little to no duct work or sheet
metal is required.
Inverter Technology
LG DFS air-source systems offer zoning without the need for zone
damper systems. The advanced controls of the four-way ceiling
cassette system provide exceptional temperature and air flow
control, and can rapidly adapt system operating parameters to the
ever changing building load. Single-zone DFS systems are easy to
design, install, and maintain. The modular design allows occupants
to control their environmental condition, providing individualized
control of the set-point temperature and allowing occupants to condi-
tion only the occupied zones.
Inverter variable-speed compressors are also measurably quieter
and consume less energy than those in conventional air condi-
tioners. The Inverter compressor ramps up or down to match the
required room capacity and maintain the comfort level. When the
selected temperature is reached, the inverter compressor operates
at low speed to maintain that comfort level, thereby using less
energy.
Quality Commitment
LG is committed to the success of DFS projects. We provide tech-
nical support during installation and commissioning. LG offers a
variety of classes designed for installers and servicer providers on
DFS installation. Classes are conducted at LG’s training centers
and in field locations at various times throughout the year and upon
special request.
