Single zone systems are available in a nominal capacity range of 3/4 to 1-1/2 tons. These are best suited for applications with zones that require heating or cooling, such as residential, and small business office buildings. Single zone wall mount outdoor and indoor units are available in V/60Hz/1Ph. Adaptable and Flexible Single zone wall mount duct-free split (DFS) systems allow cooling or heating for the entire residence or just a single room without the need for invasive ductwork. There is minimal renovation needed. 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 Inverter Technology Inverter variable-speed duct-free split systems are measurably quieter and consume less energy than 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. 6 Introduction LG Electronics U.S.A., Inc., Englewood Cliffs, NJ.

8 Product Features and Benefits Single Zone High Efficiency Wall Mount Engineering Manual Single Zone Systems Single zone 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. Utilizing multiple indoor wall mount units each with custom temperature controls allow for targeted 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 promote a quiet, comfortable environment, the LG single zone system indoor units operate at sound levels as low as 23 db(a) (19dB(A) in sleep mode) (High Efficiency Single Zone) and the outdoor units as low as 45 db(a) at full load (High Efficiency Single Zone). 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 indoor unit fan speed and refrigerant flow. LG single zone one-to-one systems continuously 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, the single zone systems deliver targeted space temperature control. Inverter Driven The single rotary (9k-12k Btu/h systems) and twin rotary (18k Btu/h systems) compressors are 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 8 Product Data 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 capacity range of 3/4 to 1-1/2 tons (depending on outdoor/indoor units). Outdoor unit operating ranges for single zone systems: Cooling: 14 F DB to 118 F DB Heating: -4 F WB to 65 F WB Installing an optional Low Ambient Wind Baffle Kit will allow operation down to 0 F in cooling mode for these single zone systems. Compact Size Single zone high efficiency outdoor units have the following footprints: LSU090HSV4, LSU120HSV4 (WxHxD (in)) 30-5/16 x 21-1/2 x 11-5/16. LSU180HSV4 (WxHxD (in)) 34-1/4 x 31-1/2 x 12-5/8. 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 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.

36 Equipment Selection Procedure Cooling/Heating Correction Factors For Single Zone High Efficiency systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction factors as shown in Figures 5-8. Multiply the correction factors by the cooling or heating capacity obtained from the capacity tables using design conditions. The resultant is the NET cooling or heating capacity.

38 Building Ventilation Design Guide Building Ventilation Design Guide ASHRAE 62.1 and local codes specify the minimum volume of outdoor air that must be provided to an occupied space. Outdoor air is required to minimize adverse health effects, and it provides acceptable indoor air quality for building occupants. The three methods of accomplishing this with single zone systems are summarized here. Single Zone High Efficiency Wall Mount Engineering Manual Although we believe that these building ventilation methods have been portrayed accurately, none of the methods have been tested, verified, or evaluated by LG Electronics, U.S.A., Inc., In all cases, the designer, installer, and contractor should understand if the suggested method is used, it is used at their own risk. LG Electronics U.S.A., Inc., takes no responsibility and offers no warranty, expressed or implied, in law or in fact, including but not limited to any implied warranty of merchantability or fitness for a particular purpose. For a complete copy of Standard , refer to the American Standard of Heating and Air Conditioning Engineers (ASHRAE) website at For more information on how to properly size a ventilation air pretreatment system, refer to the article, Selecting DOAS Equipment with Reserve Capacity by John Murphy, published in the ASHRAE Journal, April Method 1: Decoupled Dedicated Outdoor Air System (DDOAS) Provide a separate, dedicated outdoor-air system designed to filter, condition, and dehumidify ventilation air and deliver it directly to the conditioned space through a separate register or grille. This approach requires a separate independent ventilation duct system not associated with single systems (Figure 9). LG recommends using the DDOAS method in all installations. Advantages May be used with single zone systems. The outdoor air unit may supply neutral air to the occupant space even when the single zone system indoor unit fan changes speed or cycles on and off. DDOAS controls do not have to be interlocked with the single zone system. In lieu of installing localized smaller outside air treatment equipment throughout the building, this method centralizes the ventilation air source making service and filter changes easier and less disruptive for the building occupants. Third-party demand control ventilation controls are more readily accommodated. Figure 9: Decoupled Dedicated Outdoor System Diagram. Disadvantages Ceiling space is required to accommodate ductwork between the centralized outdoor air unit and ceiling diffusers. Methodology illustrations are for examples only and do not depict actual indoor units for the specific outdoor unit pairing. These are generic illustrations to show ventilation design only.

39 Building Ventilation Design Guide Method 2: Unconditioned Outdoor Air (Non-Ducted, Natural Ventilation) Natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits. The open area of a window or the free area of a louver must meet the minimum percentage of the net occupied floor area. Refer to Figure 10. Advantages Occupants control the volume of the ventilation air manually. Useful for historic buildings that have no ceiling space available for outdoor air ductwork. May be used with single zone systems. Figure 10: Unconditioned Outdoor Air (Non-Ducted). Disadvantages In some locations, it may be difficult to control humidity levels when windows are open. Thermal comfort levels may be substandard when windows are open. Indoor units may have to be oversized to account for the added heating and cooling loads when windows are open. Provides outdoor air to perimeter spaces only. Additional mechanical ventilation system may be required to satisfy requirements for interior spaces. Outdoor air loads may be difficult to calculate since the quantity of outdoor air is not regulated. May affect indoor unit proper operation when open. Methodology illustrations are for examples only and do not depict actual indoor units for the specific outdoor unit pairing. These are generic illustrations to show ventilation design only. Method 3: Unconditioned Outdoor Air (Non-Ducted, Fan Assisted Ventilation) When approved by local codes, the fan assisted ventilation method uses exhaust fans to remove air from the building, and outdoor air is drawn into occupied spaces through a wall louver or gravity roof intake hood. Supply fans can also be used to push the outdoor air into the space and building positive pressure will vent the exhaust air through louvers or roof-mounted exhaust hoods. Outdoor air is neither cooled nor heated before entering the building. Refer to Figure 11. This may result in loss of building pressurization control, increasing infiltration loads with adverse effects. Advantages Outdoor air may be manually controlled by the occupant or automatic controls may be installed to open/close outdoor air dampers or to turn on/off ventilation fans. Useful for large open spaces like warehouses, garages, and workshops. Outdoor air volume is a known quantity. Air loads may be easier to calculate since fans will regulate the amount of outdoor air. May be used with single zone systems. Disadvantages In some locations of the country, it may be difficult to control humidity levels while outdoor air louvers/hoods are opened. Thermal comfort levels may be substandard when louvers/hoods are opened. Indoor units may have to be oversized to account for the added heating/cooling loads when louvers/hoods are open. Hot, cold, and/or humid areas may be present if the outdoor air is not evenly distributed to the different spaces.
