INTRODUCTION

ARCHITECTURAL APPEAL

Convergence of Technological Innovation with Flexibility and Style

Single-Zone Four-Way CeilingCassette Systems

A four-way ceiling-cassette system provides a system designer an edge to engineer a system with many user-adjustable settings. Fourway ceiling cassette systems features a ceiling-recessed indoor unit case and an off-white architectural grille (required; sold separately) that is flush mounted, providing a clean look to the room. These systems are 208-230V/60Hz/1PH systems, available in nominal capacities of 3/4, 1, 1-1/2, 2, 3, and 3-1/2 tons, and are best suited in light commercial applications or large, open spaces. The ceiling cassette indoor unit is a useful alternative when wall space is limited.

Benefits of Four-Way Ceiling Cassette Systems

• Inverter technology

• Available in 9,000, 12,000, 18,000, 24,000, 36,000, 42,000 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 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 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 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.

Adaptable and Flexible

Four-way ceiling-cassette systems allow cooling or heating for a single room without the need for extensive remodeling. Long refrigerant piping lengths allow for extra design flexibility in indoor unit installation. These units may be used for a number of residential or commercial environments such as:

• Older homes

• New home construction

• Office buildings

• Restaurants

• Hospitals / Medical facilities

• Schools

• Nursing homes

• Retail establishments

• Houses of worship

• Indoor unit temperature setting range for 9,000 and 12,000 Btu/h of 65°F to 86°F (DB) for cooling; 61°F to 86°F (WB) for heating

• Operating ranges for 18,000, 24,000, 36,000, 42,000 Btu/h outdoor units of 5°F to +118°F (DB) for cooling; 0°F to +64°F (WB) for heating

• Operating ranges for 18,000, 24,000, 36,000, 42,000 Btu/h indoor units of 57°F to 77°F (WB) for cooling; 59°F to 81°F (DB)

Four-Way Ceiling Cassette System Engineering Manual

for heating

• Indoor unit temperature setting range for 18,000, 24,000, 36,000, and 42,000 Btu/h of 65°F to 86°F (DB) for cooling; 61°F to 86°F (WB) for heating

PRODUCT FEATURES AND BENEFITS

Four-Way Ceiling Cassette Systems

Single zone four-way ceiling cassette 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 four-way ceiling cassette indoor unit with custom temperature controls allow for precise temperature settings in each zone of the building. Four-way ceiling cassette indoor units allow flexibility in interior design and complement any decor.

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, four-way ceiling cassette indoor units operate as low as 30 dB(A) at low speed. LG customers often ask if the outdoor unit is running after commissioning is complete. All rotating components are soft-started 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, four-way ceiling cassette 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

Four-Way Ceiling Cassette System Engineering Manual

inverter technology allows the LG four-way ceiling cassette 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.

Simplified Installation

The LG four-way ceiling cassette system simplifies 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.

Operating Range

Four-way ceiling cassette systems are available in 9,000, 12,000, 18,000, 24,000, 36,000, and 42,000 Btu/h capacities.

Due to our policy of continuous product innovation, some specications may change without notication.

Clean Finish

The four-way ceiling cassette indoor unit case is recessed, while the off-white architectural grille (required, sold separately) is flush mounted, providing a clean look to the room.

Heat Transfer Efficiency

Fin Design with GoldFin™ Coating

All four-way ceiling cassette 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 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.

• Measurements taken with no attenuation and units operating at full load normal operating condition.

• Sound level will vary depending on a range of factors such as construction (acoustic absorption coefficient) of particular area in which the equipment is installed.

• Sound power levels are measured in dB(A)±3.

• Tested in anechoic chamber per ISO Standard 3745.
