by Shane Henson — October 28, 2013—LG Electronics announced that its new variable refrigerant flow (VRF) commercial air-conditioning system will be launched this fall. The system is designed to bring a new level of energy efficiency, performance and flexibility to U.S. commercial office buildings, schools, hotels and hospitals.
The Multi-V IV is the fourth generation in LG’s popular Multi-V series. It uses VRF technology that delivers significant benefits versus traditional ducted heating, ventilation, and air-conditioning (HVAC) systems, enabling improved energy efficiency by allowing occupants to choose whether to cool or heat only the zones in use, the company says. The LG Multi-V IV builds on the success of its predecessor, the Multi-V III, as LG’s flagship commercial HVAC system in the United States, where demand for high-performance, energy-saving HVAC technology continues to grow.
In addition to being exceptionally energy efficient, the LG Multi-V IV offers users a more compact footprint and is lighter in weight than other models currently on the market, says LG Electronics. Equally significant, the new Multi-V IV model allows for a wider heating and cooling operating range than its competitors.
The LG Multi-V IV also offers other benefits to building owners and managers in the market for a better HVAC system:
- AHRI 1230 Certification: The Multi-V IV is performance-certified. This ensures building owners receive verified ratings that comply with national energy codes.
- Enhanced Energy Efficiency: New compressor design and optimized heat exchanger contribute to enhanced AHRI certified efficiency of up to 28.2 IEER.
- LG Inverter Scroll: A high side shell innovation offers a more compact size for the same capacity output with greater reliability in cold climates.
- Low Ambient Heating: Heating operating range down to -13F, which provides greater comfort and saves on installation and operating costs for additional systems.
- HiPOR: High Pressure Oil Return removes efficiency losses, and Smart Oil return eliminates timed oil recovery cycles.
- Higher Elevation Piping Distances: Owners can reach extra zones further off the same VRF units with an enhanced reach of 131′ IDU to IDU. This eliminates the need to invest in extra systems and saves on installation.
- Compact and Lighter: More indoor zones, less outdoor space. When space or access is at a premium, this equates to significant cost advantages for the owner on large projects.
