Why LG VRF? DEHUMIDIFICATION AND COMFORT CONTROL EFFICIENT DESIGN Using inverters and multiple compressor water source units, the LG Multi V Water IV system offers superior load matching, which prevents constant cycling or large temperature swings. Tight temperature control through precise load matching ensures maximum comfort, efficient operation, and superior dehumidification. No need to use large distribution ducts– the Multi V Water IV removes losses that are unavoidable in other systems. With the use of optimized scroll compressors and inverter technology, Multi V Water IV systems minimize...

STYLISH DESIGN Multi V indoor units are available in a wide range of styles to complement any interior design style. With indoor unit choices including cassettes that mount flush to the ceiling, ducted units that are completely concealed in the ceiling, and mirror finished wall mounted units that fit into any decor, the LG Multi V system offers unparalleled aesthetic design. Floor Standing Work without distraction. With indoor units that can operate at sound levels as low as 23 dB(A), and outdoor units that operate as low as 49 dB(A), LG Multi V Water IV creates a comfortable environment so quiet...

Architectural Appeal ADAPTABLE AND FLEXIBLE SMALLER CHASES AND PLENUMS Multi V Water IV units are available in 208/230V as well as 460V and can adapt to a wide range of building types and sizes, including schools, hotels, retail stores, and offices. Multi V Water IV is ideal for retrofit projects where existing condenser water piping systems can be utilized. Water source units are installed indoors, eliminating the need for multiple condensing units mounted on a roof or at grade level, which allows for a cleaner exterior look to a building. For taller buildings, Multi V Water IV units offer flexibility...

The architectural and engineering community is adopting a balanced design approach that considers energy and water consumption, repetitive maintenance costs, the impact of development on the environment, and the building’s initial cost as equally important factors in developing high-performance, sustainable buildings that will increase building value. The American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the U.S. Green Building Council (USGBC) have been instrumental in developing and documenting voluntary best practice standards that provide the construction...

Multi V variable refrigerant flow air conditioning systems are engineered for sustainable green building and provides opportunities for designers to claim numerous LEED® prerequisites and points. 1. he Multi V Water IV system uses refrigerant R410A T 2. he Multi V Water IV offers exceptional energy performance by using state-of-the-art T controls and high efficiency variable speed evaporator fan assemblies with a variable speed inverter-driven compressor that provide superior load matching and energy conservation 3. he modular design of the Multi V Water IV uses multiple indoor units, allowing...

Engineering Advantage INTUITIVE DESIGN LATS Multi V design and layout software provides an intuitive method of laying out a Multi V Water IV system. LATS Multi V checks refrigerant piping lengths and elevations, and assists with the sizing of indoor and water source units by calculating capacity based on design conditions. LATS Multi V can import AutoCAD™ drawings and lay out the Multi V Water IV system to scale, without the need to add AutoCAD™ software to your computer. When the user finishes the AutoCAD™ system layout, all of the refrigerant piping lengths will be calculated and a drawing...

The benefits are numerous: modern style, mirror units for interior designers, less piping for installers, and energy efficiency for owners. LG has low sound levels, so units are quiet and can be installed inside a building. LG-manufactured inverter scroll compressors optimize system energy efficiency and are certified using AHRI Standard 1230. Variable Refrigerant Flow is a technology introduced as a system to minimize efficiency losses and provide sustainable energy benefits. LG VRF systems are engineered to save on the cost of ducts and distribution fans. VRF water systems can tie into existing...
