Duct-Free Split Systems

LG HVAC systems offer a range of solutions that are cost efficient, quiet and attractive. Duct-Free Split 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 Systems

LG Single Zone Ducted air-source systems offer zoning without the need for zone damper systems. The advanced controls of the ceiling-concealed ducted system provide exceptional building dehumidification and temperature 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 condition only the occupied zones.

Inverter variable-speed compressors are also measurably quieter and consume less energy than those in conventional air conditioners. 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 industry leading technical support during installation and commissioning. LG offers a variety of classes designed for installers and servicers to ensure that every system installation is completed successfully.

Classes are conducted at LG’s training centers and in field locations at various times throughout the year and upon special request.

• Low static available in 9,000 and 12,000 Btu/h; High static available in 24,000, and 36,000 Btu/h capacities

• All-season use—heat pump models for both cooling and heating capabilities

• Operating ranges for 9,000 and 12,000 Btu/h low static outdoor units of 0°F to +118°F (DB) for cooling (Cooling range can be extended from 0°F down to -4°F using the Low Ambient Wind Baffle Kit [sold separately]); -4°F to +64°F (WB) for heating

• Operating ranges for 9,000 and 12,000 Btu/h low static indoor units of 57°F to 77°F (WB) for cooling; 59°F to 81°F (DB) for heating

Inverter Technology

Inverter variable-speed compressors are measurably quieter and consume less energy than those in conventional air conditioners. 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.

PRODUCT FEATURES AND BENEFITS

Ceiling-Concealed Ducted Systems

Single zone ceiling-concealed ducted systems 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. Using a ducted indoor unit with custom temperature controls allow for precise temperature settings in each zone of the building. Ceiling-concealed ducted indoor units allow flexibility in interior design.

Lower Sound Levels

When outdoor units operate fully loaded, they have one of the quietest sound levels in the industry, operating as low as 47 dB(A). To promote a quiet, comfortable environment, ceiling-concealed ducted indoor units operate as low as 23 dB(A). 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. Unlike traditional air conditioning control systems, which use thermostatic controls to maintain room temperatures, LG inverters continuously vary the indoor unit fan speed and refrigerant flow, indirectly providing lower and more consistent humidity levels in the conditioned space. The longer the indoor coil temperature is below the dewpoint 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 fan motors as needed to maintain system operating pressure. As a result, ceiling-concealed ducted systems deliver precise space temperature control.

Inverter Driven

The compressor is optimized to maximize compressor efficiency, which reduces power consumption and monthly utility bills. This

Ceiling-Concealed Ducted System Engineering Manual

inverter technology allows the LG ceiling-concealed ducted outdoor unit to vary the compressor motor shaft speed and deliver an appropriate amount of cooling to the indoor unit. Occupants remain comfortable while utility costs are reduced.

Operating Range

Ceiling-concealed ducted systems are available in 9,000 and 12,000 Btu/h capacities (low static), and in 24,000 and 36,000 Btu/h capacities (high static).

9,000 and 12,000 Btu/h Low Static Operating Ranges

• Operating ranges for outdoor units of 0°F to +118°F (DB) for cooling (Cooling range can be extended from 0°F down to -4°F using the Low Ambient Wind Baffle Kit [sold separately]); -4°F to +64°F (WB) for heating.

• Operating ranges for indoor units of 57°F to 77°F (WB) for cooling; 59°F to 81°F (DB) for heating.

• Indoor unit temperature setting range of 65°F to 86°F (DB) for cooling; 61°F to 86°F (WB) for heating.

24,000 and 36,000 High Static Operating Ranges

• Operating ranges for outdoor units of 5°F to +118°F (DB) for cooling; 0°F to +64°F (WB) for heating.

• Operating ranges for indoor units of 57°F to 77°F (WB) for cooling; 59°F to 81°F (DB) for heating.

• Indoor unit temperature setting range of 65°F to 86°F (DB) for cooling; 61°F to 86°F (WB) for heating

Heat Transfer Efficiency

Fin Design with GoldFin™ Coating

All ceiling-concealed ducted 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, the LG ceilingconcealed ducted 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 development 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 heating operation. This coating also makes it possible to easily clean the outdoor unit coil using a mild soap.

Other Features

Simplified Installation

The LG ceiling-concealed ducted system simplies and reduces

mechanical and control system design time. The designer no longer has to be concerned with interconnecting chilled and condenser water piping, complicated air distribution duct systems, matching and selecting chillers, towers, pumps, coils, fans, air handlers, or Variable Air Volume (VAV) boxes.

Setting the External Static Pressure on the Remote Controller

Use this function to set the wind strength for each airflow level.

• The external static pressure must be set by a trained service provider, and it must be set correctly. If the external static pressure is set incorrectly, the product may malfunction.

• Do not alter the external static pressure value that corresponds to each airflow level.

• External static pressure values vary according to the model.

• When the airflow rate is increased to a higher value, during the external static value setup, the previous airflow value will be stored in the system memory. (External static pressure values are saved to system memory before the changes are implemented).
